4. Clinical particulars
4.1 Therapeutic indications

Oral contraception.

The decision to prescribe Lestramyl®150/20 micrograms tablets should take into consideration the individual woman's current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with Lestramyl®150/20 micrograms tablets compares with other CHCs (see sections 4.3 and 4.4).

4.2 Posology and method of administration


How to take Lestramyl®150/20 micrograms tablets

The tablets must be taken every day at about the same time, if necessary with a little liquid, in the order shown on the blister pack. One tablet is to be taken daily for 21 consecutive days. Each subsequent pack is started after a 7-day tablet-free interval; during which time a withdrawal bleed usually occurs. This usually starts on day 2-3 after the last tablet and may not have finished before the next pack is started.

How to start Lestramyl®150/20 micrograms tablets

No preceding hormonal contraceptive use (in the past month)

Tablet-taking has to start on day 1 of the woman's natural cycle (i.e. the first day of her menstrual bleeding). Tablet intake is also allowed to start on day 2-5, but during the first cycle concurrent use of a barrier method for the first 7 days of tablet intake is advisable.

Changing from a combined hormonal contraceptive (combined oral contraceptive (COC), vaginal ring or transdermal patch)

The woman should start taking Lestramyl®150/20 micrograms tablets preferably on the day after the last active tablet (the last tablet containing the active substances) of her previous COC, but at the latest on the day following the usual tablet-free or placebo tablet interval of her previous COC. In case a vaginal ring or a transdermal patch has been used, the woman should start using Lestramyl®150/20 micrograms tablets preferably on the day of removal, but at the latest when the next application would have been due. Under no circumstances should the hormone-free period of her previous method be extended beyond the recommended duration.

If the woman consistently and correctly used her previous combined hormonal contraceptive during the previous 7 days, and it is reasonably certain that she is not pregnant she may switch to Lestramyl®150/20 micrograms tablets at any day of the cycle of her previous combined hormonal contraceptive method.

It is possible that not all the described methods of contraception (e.g. vaginal ring, transdermal patch) are available in all EU countries.

Changing from a progestogen-only-method (progestogen-only-pill, injection, implant) or from a progestogen-releasing intrauterine system (IUS)

The woman may switch any day from the progestogen-only pills (from an implant or the IUS on the day of its removal; from an injectable when the next injection would be due) but should in all of these cases be advised to additionally use a barrier method for the first 7 days of tablet-taking.

Following first-trimester abortion

The woman may start immediately. When doing so, she need not take additional contraceptive measures.

Following delivery or second-trimester abortion

The woman should be advised to start at day 21 to 28 after delivery or second-trimester abortion. When starting later, the woman should be advised to additionally use a barrier method for the first 7 days. However if intercourse has already occurred, pregnancy should be excluded before the actual start of COC use or the woman has to wait for her first menstrual period.

For breast-feeding women - see section 4.6.

Management of missed tablets

If the user is less than 12 hours late in taking any tablet, contraceptive protection is not reduced.

The woman should take the tablet as soon as she remembers, and should take further tablets at the usual time.

If she is more than 12 hours late in taking any tablet, contraceptive protection may be reduced. The management of missed tablets can be guided by the following two basic rules:

1. tablet-taking must never be interrupted for longer than 7 days

2. 7 days of uninterrupted tablet-taking are required to attain adequate suppression of the hypothalamus-pituitary-ovarian-axis.

Accordingly the following advice can be given in daily practice:

Week 1

The user should take the last missed tablet as soon as she remembers, even if this means taking two tablets at the same time. She then continues to take tablets at her usual time. In addition, a barrier method (such as a condom) should be used for the next 7 days. If intercourse took place in the preceding 7 days, the possibility of a pregnancy should be considered. The more tablets are missed and the closer they are to the regular tablet-free interval, the higher the risk of a pregnancy.

Week 2

The user should take the last missed tablet as soon as she remembers, even if this means taking two tablets at the same time. She then continues to take tablets at her usual time. Provided that the woman has taken her tablets correctly in the 7 days preceding the first missed tablet, there is no need to use extra contraceptive precautions. However, if she has missed more than 1 tablet, the woman should be advised to use extra contraceptive precautions for 7 days.

Week 3

The risk of reduced reliability is imminent because of the forthcoming 7-day tablet-free interval. However, by adjusting the tablet-intake schedule, reduced contraceptive protection can still be prevented. By adhering to either of the following two options, there is no need to use extra contraceptive precautions, provided that in the 7 days preceding the first missed tablet the woman has taken all tablets correctly. If this is not the case, she should follow the first of these two options and use extra contraceptive precautions for the next 7 days as well.

1. The user should take the last missed tablet as soon as she remembers, even if this means taking two tablets at the same time. She then continues to take tablets at her usual time. The next blister pack must be started as soon as the current blister pack is finished, i.e. no gap should be left between packs. The user is unlikely to have a withdrawal bleed until the end of the second pack, but she may experience spotting or breakthrough bleeding on tablet-taking days.

2. The user may also be advised to discontinue tablet-taking from the current blister pack. She should then have a tablet-free interval of up to 7 days, including the days she missed tablets, and subsequently continue with the next blister pack.

If the woman missed tablets and subsequently has no withdrawal bleed in the first normal tablet-free interval, the possibility of a pregnancy should be considered.

Advice in case of gastrointestinal disturbances

In case of severe gastrointestinal disturbances (e.g. vomiting or diarrhoea), absorption may not be complete and additional contraceptive measures should be taken.

If vomiting occurs within 3-4 hours after tablet-taking, a new (replacement) tablet should be taken as soon as possible. The new tablet should be taken within 12 hours of the usual time of tablet-taking if possible. If more than 12 hours elapse, the advice concerning missed tablets, under section “Management of missed tablets”, is applicable. If the woman does not want to change her normal tablet-taking schedule, she has to take the extra tablet(s) from another blister pack.

How to postpone a withdrawal bleed

Delaying the monthly bleed is not an indication for the product. However, to delay a period in exceptional cases the woman can continue with another blister pack of Lestramyl®150/20 micrograms tablets without a tablet-free interval. The extension can be carried on for as long as wished, but not longer than the end of the second pack. During the extension the woman may experience breakthrough-bleeding or spotting. Regular intake of Lestramyl®150/20 micrograms tablets is then resumed after the usual 7-day tablet-free interval.

To shift her periods to another day of the week than the woman is used to with her current scheme, she can be advised to shorten her forthcoming tablet-free interval by as many days as she likes. The shorter the interval, the higher the risk that she does not have a withdrawal bleed and will experience breakthrough-bleeding and spotting during the subsequent pack (just as when delaying a period).

Paediatric population

The safety and efficacy of desogestrel/ethinylestradiol in adolescents below 18 years has not yet been established. No data are available.

Method of administration

Oral use.

4.3 Contraindications

Combined hormonal contraceptives (CHCs) should not be used in the following conditions. Should any of the conditions appear for the first time during COC use, the medicinal product should be stopped immediately.

• Presence or risk of venous thromboembolism (VTE)

o Venous thromboembolism – current VTE (on anticoagulants) or history of (e.g. deep venous thrombosis (DVT) or pulmonary embolism (PE))

o Known hereditary or acquired predisposition for venous thromboembolism, such as APC-resistance, (including Factor V Leiden), antithrombin-III-deficiency, protein C deficiency, protein S deficiency

o Major surgery with prolonged immobilisation (see section 4.4)

o A high risk of venous thromboembolism due to the presence of multiple risk factors (see section 4.4)

• Presence or risk of arterial thromboembolism (ATE)

o Arterial thromboembolism – current arterial thromboembolism, history of arterial thromboembolism (e.g. myocardial infarction) or prodromal condition (e.g. angina pectoris)

o Cerebrovascular disease – current stroke, history of stroke or prodromal condition (e.g. transient ischaemic attack, TIA)

o Known hereditary or acquired predisposition for arterial thromboembolism, such as hyperhomocysteinaemia and antiphospholipid-antibodies (anticardiolipin-antibodies, lupus anticoagulant)

o History of migraine with focal neurological symptoms

o A high risk of arterial thromboembolism due to multiple risk factors (see section 4.4) or to the presence of one serious risk factor such as:

o diabetes mellitus with vascular symptoms

o severe hypertension

o severe dyslipoproteinaemia.

- Pancreatitis or a history thereof if associated with severe hypertriglyceridaemia

- Presence or history of severe hepatic disease as long as liver function values have not returned to normal.

- Presence or history of liver tumours (benign or malignant).

- Known or suspected sex steroid-influenced malignancies (e.g. of the genital organs or the breasts)

- Undiagnosed vaginal bleeding.

- Endometrial hyperplasia

- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.

Lestramyl®150/20 micrograms tablets is contraindicated for concomitant use with the medicinal products containing ombitasvir/paritaprevir/ritonavir and dasabuvir, (see sections 4.4 and section 4.5).

4.4 Special warnings and precautions for use


If any of the conditions or risk factors mentioned below is present, the suitability of Lestramyl®150/20 micrograms tablets should be discussed with the woman.

In the event of aggravation, or first appearance of any of these conditions or risk factors, the woman should be advised to contact her doctor to determine whether the use of Lestramyl®150/20 micrograms tablets should be discontinued.

Risk of venous thromboembolism (VTE)

The use of any combined hormonal contraceptive (CHC) increases the risk of venous thromboembolism (VTE) compared with no use. Products that contain levonorgestrel, norgestimate or norethisterone are associated with the lowest risk of VTE. Other products such as Lestramyl®150/20 micrograms tablets may have up to twice this level of risk. The decision to use any product other than one with the lowest VTE risk should be taken only after a discussion with the woman to ensure she understands the risk of VTE with Lestramyl®150/20 micrograms tablets, how her current risk factors influence this risk, and that her VTE risk is highest in the first ever year of use. There is also some evidence that the risk is increased when a CHC is re-started after a break in use of 4 weeks or more.

In women who do not use a CHC and are not pregnant about 2 out of 10,000 will develop a VTE over the period of one year. However, in any individual woman the risk may be far higher, depending on her underlying risk factors (see below).

It is estimated1 that out of 10,000 women who use a CHC containing desogestrel, between 9 and 12 women will develop a VTE in one year; this compares with about 62 in women who use a levonorgestrel-containing CHC.

In both cases, the number of VTEs per year is fewer than the number expected during pregnancy or in the postpartum period.

VTE may be fatal in 1-2% of cases.

Number of VTE events per 10,000 women in one year

Extremely rarely, thrombosis has been reported to occur in CHC users in other blood vessels, e.g. hepatic, mesenteric, renal or retinal veins and arteries.

Risk factors for VTE

The risk for venous thromboembolic complications in CHC users may increase substantially in a woman with additional risk factors, particularly if there are multiple risk factors (see table).

Lestramyl®150/20 micrograms tablets is contraindicated if a woman has multiple risk factors that put her at high risk of venous thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors – in this case her total risk of VTE should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).

Table: Risk factors for VTE

Risk factor


Obesity (body mass index over 30 kg/m²)

Risk increases substantially as BMI rises.

Particularly important to consider if other risk factors also present.

Prolonged immobilisation, major surgery, any surgery to the legs or pelvis, neurosurgery, or major trauma

Note: temporary immobilisation including air travel >4 hours can also be a risk factor for VTE, particularly in women with other risk factors

In these situations it is advisable to discontinue use of the patch/pill/ring (in the case of elective surgery at least four weeks in advance) and not resume until two weeks after complete remobilisation. Another method of contraception should be used to avoid unintentional pregnancy.

Antithrombotic treatment should be considered if desogestrel/ethinylestradiol has not been discontinued in advance.

Positive family history (venous thromboembolism ever in a sibling or parent especially at a relatively early age e.g. before 50).

If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use

Other medical conditions associated with VTE

Cancer, systemic lupus erythematosus, haemolytic uraemic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis) and sickle cell disease

Increasing age

Particularly above 35 years

There is no consensus about the possible role of varicose veins and superficial thrombophlebitis in the onset or progression of venous thrombosis.

The increased risk of thromboembolism in pregnancy, and particularly the 6 week period of the puerperium, must be considered (for information on “Pregnancy and lactation” see section 4.6).

Symptoms of VTE (deep vein thrombosis and pulmonary embolism)

In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.

Symptoms of deep vein thrombosis (DVT) can include:

• unilateral swelling of the leg and/or foot or along a vein in the leg;

• pain or tenderness in the leg which may be felt only when standing or walking,

• increased warmth in the affected leg; red or discoloured skin on the leg.

Symptoms of pulmonary embolism (PE) can include:

• sudden onset of unexplained shortness of breath or rapid breathing;

• sudden coughing which may be associated with haemoptysis;

• sharp chest pain;

• severe light headedness or dizziness;

• rapid or irregular heartbeat.

Some of these symptoms (e.g. “shortness of breath”, “coughing”) are non-specific and might be misinterpreted as more common or less severe events (e.g. respiratory tract infections).

Other signs of vascular occlusion can include: sudden pain, swelling and slight blue discoloration of an extremity.

If the occlusion occurs in the eye symptoms can range from painless blurring of vision which can progress to loss of vision. Sometimes loss of vision can occur almost immediately.

Occurrence of one or more of these symptoms may be a reason for immediate discontinuation of Lestramyl®150/20 micrograms tablets usage.

Risk of arterial thromboembolism (ATE)

Epidemiological studies have associated the use of CHCs with an increased risk for arterial thromboembolism (myocardial infarction) or for cerebrovascular accident (e.g. transient ischaemic attack, stroke). Arterial thromboembolic events may be fatal.

Risk factors for ATE

The risk of arterial thromboembolic complications or of a cerebrovascular accident in CHC users increases in women with risk factors (see table). Lestramyl®150/20 micrograms tablets is contraindicated if a woman has one serious or multiple risk factors for ATE that puts her at high risk of arterial thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors - in this case her total risk should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).

Table: Risk factors for ATE

Risk factor


Increasing age

Particularly above 35 years


Women should be advised not to smoke if they wish to use a CHC. Women over 35 who continue to smoke should be strongly advised to use a different method of contraception


Obesity (body mass index over 30 kg/m2)

Risk increases substantially as BMI increases.

Particularly important in women with additional risk factors

Positive family history (arterial thromboembolism ever in a sibling or parent especially at relatively early age e.g. below 50).

If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use


An increase in frequency or severity of migraine during CHC use (which may be prodromal of a cerebrovascular event) may be a reason for immediate discontinuation

Other medical conditions associated with adverse vascular events

Diabetes mellitus, hyperhomocysteinaemia, valvular heart disease and atrial fibrillation, dyslipoproteinaemia and systemic lupus erythematosus.

Symptoms of ATE

In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.

Symptoms of a cerebrovascular accident can include:

• sudden numbness or weakness of the face, arm or leg, especially on one side of the body;

• sudden trouble walking, dizziness, loss of balance or coordination;

• sudden confusion, trouble speaking or understanding;

• sudden trouble seeing in one or both eyes;

• sudden, severe or prolonged headache with no known cause;

• loss of consciousness or fainting with or without seizure.

Temporary symptoms suggest the event is a transient ischaemic attack (TIA).

Symptoms of myocardial infarction (MI) can include:

• pain, discomfort, pressure, heaviness, sensation of squeezing or fullness in the chest, arm, or below the breastbone;

• discomfort radiating to the back, jaw, throat, arm, stomach;

• feeling of being full, having indigestion or choking;

• sweating, nausea, vomiting or dizziness;

• extreme weakness, anxiety, or shortness of breath;

• rapid or irregular heartbeats.

The presence of one serious risk factor or multiple risk factors for venous or arterial disease, respectively, can also constitute a contra-indication. The possibility of anticoagulant therapy should also be taken into account. COC users should be specifically pointed out to contact their physician in case of possible symptoms of thrombosis. In case of suspected or confirmed thrombosis, COC use should be discontinued. Adequate alternative contraception should be initiated because of the teratogenicity of anticoagulant therapy (coumarins).


Epidemiological studies indicate that the long-term use of oral contraceptives displays a risk factor for the development of cervical cancer in women infected with human papillomavirus (HPV). However, there is still uncertainty about the extent to which this finding is influenced by confounding effects (e.g. differences in number of sexual partners or in use of barrier contraceptives).

A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk (RR = 1.24) of having breast cancer diagnosed in women who are currently using COC. The excess risk gradually disappears during the course of the 10 years after cessation of COC use. Because breast cancer is rare in women under 40 years of age, the excess number of breast cancer diagnoses in current and recent users of COC is small in relation to the overall risk of breast cancer. These studies do not provide evidence for causation. The observed pattern of increased risk may be due to an earlier diagnosis of breast cancer in users of COC, the biological effects of COCs or a combination of both. The breast cancers diagnosed in ever-users tend to be less advanced clinically than the cancers diagnosed in never-users.

In rare cases, benign liver tumours, and even more rarely malignant liver tumours have been reported in users of COCs. In isolated cases, these tumours have led to life-threatening intra-abdominal haemorrhages. A hepatic tumour should be considered in the differential diagnosis when severe upper abdominal pain, liver enlargement or signs of intra-abdominal haemorrhage occur in women taking COCs.

Other conditions

Women with hypertriglyceridaemia or a family history thereof, may be at an increased risk of pancreatitis when using COCs.

Although small increases in blood pressure have been reported in many women taking COCs, clinically relevant increases are rare. Only in these rare cases an immediate discontinuation of COC use is justified. A systematic relationship between COC use and clinical hypertension has not been established. However, if sustained clinically significant hypertension develops during the use of a COC then it is prudent for the physician to withdraw the COC and treat the hypertension. Where considered appropriate, COC use may be resumed if normotensive values can be achieved with antihypertensive therapy.

The following conditions have been reported to occur or deteriorate with both pregnancy and COC use, but the evidence of an association with COC use is inconclusive: jaundice and/or pruritus related to cholestasis; gallstone formation; porphyria; systemic lupus erythematosus; haemolytic uraemic syndrome; Sydenham's chorea; herpes gestationis; otosclerosis-related hearing loss.

In women with hereditary angioedema exogenous estrogens may induce or exacerbate symptoms of angioedema.

Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal. Recurrence of cholestatic jaundice which occurred first during pregnancy or and/or cholestasis-related pruritus which previously occurred during pregnancy or during previous use of sex steroids necessitates the discontinuation of COCs.

Although COCs may have an effect on peripheral insulin resistance and glucose tolerance, there is no evidence for a need to alter the therapeutic regime in diabetics using COCs. However, diabetic women should be carefully observed while taking COCs, particularly in the early stage of COC use.

Worsening of endogenous depression, of epilepsy, of Crohn's disease and ulcerative colitis have been associated with COC use.

Chloasma may occasionally occur, especially in women with a medical history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation whilst taking COCs.

When counselling the choice of contraceptive method(s), all the above information should be taken into account.

ALT elevations

During clinical trials with patients treated for hepatitis C virus infections (HCV) with the medicinal products containing ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin, transaminase (ALT) elevations higher than 5 times the upper limit of normal (ULN) occurred significantly more frequent in women using ethinylestradiol-containing medications such as combined hormonal contraceptives (CHCs) (see sections 4.3 and 4.5).

Medical Examination/Consultation

Prior to the initiation or reinstitution of Lestramyl®150/20 micrograms tablets a complete medical history (including family history) should be taken and pregnancy must be ruled out. Blood pressure should be measured and if clinically indicated a physical examination should be performed, guided by the contraindications (see section 4.3) and warnings (see section 4.4). It is important to draw a woman's attention to the information on venous and arterial thrombosis, including the risk of Lestramyl®150/20 micrograms tablets compared with other COCs, the symptoms of VTE and ATE, the known risk factors and what to do in the event of a suspected thrombosis.

The woman should also be instructed to carefully read the user leaflet and to adhere to the advice given. The frequency and nature of further periodic examinations should be based on established practice guidelines and be adapted to the individual woman.

Women should be advised that oral contraceptives do not protect against HIV infections (AIDS) and other sexually transmitted diseases.

Reduced efficacy

The efficacy of COCs may be reduced in the event of e.g. missed tablets (see section 4.2 “Management of missed tablets”), gastro-intestinal disturbances (see section 4.2 ”Advice in case of gastrointestinal disturbances") or concomitant use with other medicinal products that reduce the plasma concentration of ethinylestradiol and/or etonogestrel, the active metabolite of desogestrel(see section 4.5).

Herbal preparations containing St. John's wort (Hypericum perforatum) should not be used while taking Lestramyl®150/20 micrograms tablets due to the risk of decreased plasma concentrations and reduced clinical effects of Lestramyl®150/20 micrograms tablets (see section 4.5).

Reduced cycle control

With all COCs, irregular bleeding (spotting and breakthrough bleeding) may occur, especially during the first months of use. Therefore, the evaluation of any irregular bleeding is only meaningful after an adaptation interval of about 3 cycles.

If bleeding irregularities persist or occur after previously regular cycles, then non-hormonal causes should be considered and adequate diagnostic measures are indicated to exclude malignancy or pregnancy. These may include curettage.

In some women withdrawal bleeding may not occur during the tablet-free interval. If the COC has been taken according to the directions described in section 4.2, it is unlikely that the woman is pregnant. However, if the COC has not been taken according to these directions prior to the first missed withdrawal bleed or if two withdrawal bleeds are missed, pregnancy must be ruled out before COC use is continued.

Lestramyl®150/20 micrograms tablets contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicinal product.

1 These incidences were estimated from the totality of the epidemiological study data, using relative risks for the different products compared with levonorgestrel-containing CHCs.

2 Mid-point of range of 5-7 per 10,000 WY, based on a relative risk for CHCs containing levonorgestrel versus non-use of approximately 2.3 to 3.6

4.5 Interaction with other medicinal products and other forms of interaction

Note: The prescribing information of concomitant medications should be consulted to identify potential interactions.

Pharmacodynamic interactions

Concomitant use with the medicinal products containing ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without ribavirin may increase the risk of ALT elevations (see sections 4.3 and 4.4). Therefore, Lestramyl®150/20 micrograms tablets -users must switch to an alternative method of contraception (e.g., progestagen-only contraception or non-hormonal methods) prior to starting therapy with this combination drug regimen. Lestramyl®150/20 micrograms tablets can be restarted 2 weeks following completion of treatment with this combination drug regimen.

Effects of other medicinal products on desogestrel/ethinylestradiol

Interactions may occur with medicinal products or herbal remedies, that induce microsomal enzymes, in particular the cytochrome P450 enzymes (CYP), which can result in increased clearance of sex hormones and which may lead to breakthrough bleeding, and/or pregnancy.


Enzyme induction can already be observed after a few days of treatment. Maximal enzyme induction is generally seen within a few weeks. After the cessation of drug therapy enzyme induction may be sustained for about 4 weeks.

Short-term treatment

Women on treatment with enzyme-inducing medicinal or herbal products should temporarily use a barrier method or another method of contraception in addition to the COC.

The barrier method must be used during the whole time of the concomitant drug therapy and for 28 days after stopping treatment. If the drug therapy runs beyond the end of the tablets in the COC pack, the next COC pack should be started right after the previous one without the usual tablet-free interval.

Long-term treatment

In women on long-term treatment with enzyme-inducing active substances, another reliable, non-hormonal, method of contraception is recommended.

The following interactions are known in the literature.

Substances that increase the clearance of desogestrel/ethinylestradiol (enzyme induction), for example:

Phenytoin, phenobarbital, primidone, bosentan, carbamazepine, rifampicin, some HIV protease inhibitors (e.g. ritonavir) and non-nucleoside reverse transcriptase inhibitors (e.g. efavirenz, nevirapine) and possibly also oxcarbazepine, topiramate, rifabutin, felbamate, griseofulvin and products that include the herbal remedy St John's Wort (Hypericum perforatum).

Substances with variable effects on the clearance of desogestrel/ethinylestradiol

When co-administered with hormonal contraceptives, many combinations of HIV protease inhibitors (e.g. nelfinavir) and non-nucleoside reverse, transcriptase inhibitors (for example nevirapine) and/or combinations with hepatitis C virus (HCV) inhibitors (for example boceprevir, telaprevir) may increase or decrease the plasma concentrations of progestogens, including etonogestrel or oestrogens. In some cases, the net effect of these changes may be clinically relevant.

Therefore, the prescribing information of concomitant HIV/HCV medication should be consulted to identify possible interactions and any related recommendations. In case of any doubt, an additional barrier contraceptive should be used by women treated with protease inhibitors or non-nucleoside reverse transcriptase inhibitors.

Substances that reduce the clearance of desogestrel/ethinylestradiol (enzyme inhibitors)

The clinical relevance of possible interactions with enzyme inhibitors remains unknown. Concomitant use of strong (e.g. ketoconazole, itraconazole, clarithromycin) or moderate (e.g. fluconazole, diltiazem erythromycin) CYP3A4-inhibitors may increase the plasma concentrations of oestrogens or progestogens, including etonogestrel.

Doses of etoricoxib of 60 to 120 mg/day have been shown to increase plasma concentrations of ethinylestradiol 1.4 to 1.6-fold, respectively when taken concomitantly with a combined hormonal contraceptive that contained 0.035 mg ethinylestradiol.

Influence of desogestrel/ethinylestradiol on other medicinal products

Combined oral contraceptives may affect the metabolism of certain other medicinal products. Accordingly, plasma and tissue concentrations may either increase (e.g. ciclosporin) or decrease (e.g. lamotrigine).

Clinical data suggest that ethinylestradiol suppresses the clearance of CYP1A2 substrates, which leads to a weak (e.g. theophylline) or moderate (e.g. tizanidine) increase in the plasma concentrations of these medicinal products.

Laboratory Tests

The use of contraceptive steroids may influence the results of certain laboratory tests, including biochemical parameters of liver, thyroid, adrenal and renal function; plasma levels of (carrier) proteins, e.g. corticosteroid-binding globulin and lipid/lipoprotein fractions, parameters of carbohydrate metabolism and parameters of coagulation and fibrinolysis. Changes generally remain within the normal laboratory range.

4.6 Fertility, pregnancy and lactation


Lestramyl®150/20 micrograms tablets is not indicated in pregnancy.

If pregnancy occurs during treatment with Lestramyl®150/20 micrograms tablets, further intake should be stopped. However, most epidemiological studies have revealed neither an increased risk of birth defects in children born to women who used COCs prior to pregnancy, nor a teratogenic effect when COCs were taken inadvertently during early pregnancy.

The increased risk of VTE during the postpartum period should be considered when re-starting Lestramyl®150/20 micrograms tablets (see sections 4.2 and 4.4).


Lactation may be influenced by COCs as they may reduce the quantity and change the composition of breast milk. Therefore, the use of COCs should generally not be recommended until the nursing mother has completely weaned her child. Small amounts of the contraceptive steroids and/or their metabolites may be excreted in the milk however, there is no evidence that this has a detrimental effect on the child's health.

4.7 Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed.

No effects on ability to drive and use machines have been observed in users of COCs.

4.8 Undesirable effects

As with all COCs, changes in vaginal bleeding patterns may occur, especially during the first months of use. These may include changes in bleeding frequency (absent, less, more frequent or continuous), intensity (reduced or increased) or duration.

Possibly related undesirable effects that have been reported in users of desogestrel/ethinylestradiol, or COC users in general are listed in the table below1. All ADRs are listed by system organ class and frequency: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100) and rare (<1/1,000).

1 The most common appropriate MedDRA term to describe a certain adverse reaction is listed. Synonyms or related conditions are not listed, but should be taken into account as well.

Description of selected adverse reactions

An increased risk of arterial and venous thrombotic and thromboembolic events, including myocardial infarction, stroke, transient ischaemic attacks, venous thrombosis and pulmonary embolism has been observed in women using CHCs, which are discussed in more detail in section 4.4.

The following serious adverse events have been reported in women using COCs and are also discussed in section 4.4:

- Hypertension;

- Hormone-dependent tumours (e.g. liver tumours, breast cancer, cervical cancer);

- Occurrence or deterioration of conditions for which an association with OC use is not conclusive: Crohn's disease, ulcerative colitis, epilepsy, migraine, endometriosis, uterine myoma, porphyria, systemic lupus erythematosus, herpes gestationis, Sydenham's chorea, haemolytic uraemic syndrome, cholestatic jaundice;

- Chloasma;

- Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal.

- In women with hereditary angioedema exogenous estrogens may induce or exacerbate symptoms of angioedema.

The frequency of diagnosis of breast cancer is very slightly increased among OC users. As breast cancer is rare in women under 40 years of age the excess number is small in relation to the overall risk of breast cancer. Causation with COC use is unknown. For further information, see sections 4.3 and 4.4.


Breakthrough bleeding and/or reduced reliability may be the result of interactions of other medicinal products (enzyme inducers) with oral contraceptives (see section 4.5).

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at:

4.9 Overdose

There have been no reports of serious deleterious effects from overdose.

Symptoms that may occur in this case are: nausea, vomiting and, in young girls, slight vaginal bleeding. There are no antidotes and further treatment should be symptomatic.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Sex hormones and modulators of the genital system. Progestogens and estrogens, fixed combinations, ATC code: G03AA09

The contraceptive action of COCs is based on interaction of different factors, out of which the most important is the inhibition of ovulation and changes in the cervical secretion. Besides protection against pregnancy, COCs have several positive properties which, next to the negative properties (see sections 4.4 and 4.8), can be useful in deciding on the method of birth control. The cycle is more regular and the menstruation is often less painful and bleeding is lighter. The latter may result in a decrease in the occurrence of iron deficiency. In the largest multicenter trial (n=23 258 cycles), the uncorrected Pearl Index is estimated at 0.1 (95% confidence interval 0.0-0.3). Furthermore, 4.5% of the women reported absence of withdrawal bleeding and 9.2% reported occurrence of irregular bleeding after 6 treatment cycles.

Lestramyl®150/20 micrograms tablets is a COC with ethinylestradiol and the progestogen desogestrel. Ethinylestradiol is a well known synthetic estrogen. Desogestrel is a synthetic progestogen. After oral administration it has a strong ovulation-inhibiting activity.

With the use of the higher-dosed COCs (50 μg ethinylestradiol) the risk of endometrial and ovarian cancer is reduced. Whether this also applies to lower-dosed COCs remains to be confirmed.

Paediatric population

No clinical data on efficacy and safety are available in adolescents below 18 years.

5.2 Pharmacokinetic properties



After oral administration of Lestramyl®150/20 micrograms tablets, desogestrel is rapidly and completely absorbed and converted to etonogestrel. Peak plasma levels of approximately 2 ng/mL are reached after 1.5 hours. Bioavailability is 62-81 %.


Etonogestrel is bound to the plasma proteins, mainly serum albumin and to sex hormone-binding globulin (SHBG). Only 2-4 % of the total serum concentrations are present as free steroid; 40-70 % are specifically bound to SHBG. The ethinylestradiol-induced increase in SHBG influences the distribution over the serum proteins, causing an increase of the SHBG-bound fraction and a decrease of the albumin-bound fraction. The volume of distribution of desogestrel is 1.5 L/kg.


Etonogestrel is completely metabolised by the known pathways of steroid metabolism. Etonorgestrel is reduced and its degradation products are conjugated to sulfate and glucuronides.

The metabolic clearance rate of etonogestrel from serum is about 2 mL/min/kg. Animal studies indicate that the enterohepatic circulation has no relevance for the gestagenic activity of desogestrel. No interaction was found with co-administered ethinylestradiol.


The serum concentration of etonogestrel decreases in two phases. The terminal elimination phase is characterised by a half-life of approximately 30 hours and plasma clearance varies from 5.0-9.5 l/hour. Desogestrel and its metabolites are excreted at a urinary/biliary ratio of approximately 6:4.

Steady-State Conditions

Etonogestrel pharmacokinetics are influenced by SHBG levels, which are increased by a factor of three by ethinylestradiol. Following daily ingestion, serum levels increase by a factor of two to three, reaching steady-state conditions during the second half of a treatment cycle.



Ethinylestradiol is rapidly and completely absorbed after oral administration. Following ingestion of a single dose peak plasma levels of approximately 80 pg/mL are reached after 1-2 hours. Absolute bioavailability as a result of presystemic conjugation and first-pass metabolism is approximately 60 %.


Ethinylestradiol is highly but non-specifically bound to serum albumin (approximately 98.5 %) and induces an increase in the serum concentrations of SHBG. Distribution volume has been determined as approximately 5 L/kg.


Ethinylestradiol is subject to presystemic conjugation in both small bowel mucosa and the liver. Ethinylestradiol is primarily metabolised by aromatic hydroxylation, but a wide variety of hydroxylated and methylated metabolites are formed, which occur as free metabolites or as glucuronide or sulfate conjugates. The metabolic clearance rate of ethinylestradiol from serum is approximately 5 mL/min/kg. In vitro ethinylestradiol is a reversible inhibitor of CYP2C19, CYP1A1 and CYP1A2, and is also a mechanism based inhibitor of CYP3A4/5, CYP2C8 and CYPP2J2.


Ethinylestradiol serum concentration decreases in two phases; the terminal disposition phase is characterised by a half-life of approximately 24 hours. Unchanged ethinylestradiol is not excreted. The metabolites of ethinylestradiol are excreted at a urinary/biliary ratio of 4:6. The half-life of metabolite excretion is approximately 1 day.

Steady-state conditions

Steady-state conditions are obtained after 3 to 4 days, when the serum drug level is approx. 30 to 40 % higher than after the administration of a single dose.

5.3 Preclinical safety data

Preclinical data shows no particular risk to humans when COCs are used according to instructions. This conclusion is based on conventional studies of repeated dose toxicity, genotoxicity, carcinogenic studies and reproduction toxicity studies. However, it must be remembered that sex hormones can promote the growth of certain hormone-dependent tissues and tumours.
