Before you start using Lizinna you should read the information on blood clots in section 2.1. It is particularly important to read the symptoms of a blood clot - see Section 2.1 ‘The Pill and blood clots’.
It is important that you understand the benefits and risks of taking Lizinna before you start taking it, or when deciding whether to carry on taking it. Although Lizinna is suitable for most healthy women it is not suitable for everyone.
Using a Pill such as Lizinna increases your risk of developing a blood clot compared with not using one. In rare cases a blood clot can block blood vessels and cause serious problems.
Blood clots can develop
- in veins (referred to as ana ‘venous thrombosis’, ‘venous thromboembolism’ or VTE)
- in the arteries (referred to as an ‘arterial thrombosis’, ‘arterial thromboembolism’ or ATE)
Recovery from blood clots is not always complete. Rarely, there may be serious lasting effects or very rarely they may be fatal.
It is important to remember that the overall risk of a harmful blood clot caused by Lizinna is small.
How to recognise a blood clot
Seek urgent medical attention if you notice any of the following signs or symptoms.
Do you have any of these signs?
- swelling of one leg or along a vein in the leg or foot especially with:
- pain or tenderness in the leg which may be felt only when standing or walking
- increased warmth in the affected leg
- change in colour of the skin on the leg such as turning pale, red or blue.
What could you be suffering from?
Deep vein thrombosis (DVT) (blood clot in the large vein of the leg)
Do you have any of these signs?
- sudden unexplained breathlessness or rapid breathing
- sudden cough without an obvious cause, which may bring up blood
- sharp chest pain which may increase with deep breathing
- severe light headedness or dizziness
- rapid or irregular heartbeat
- severe pain in your stomach
If you are unsure, talk to a doctor as some of these symptoms such as coughing or being short of breath may be mistaken for a milder condition such as a respiratory tract infection (like a common cold).
What could you be suffering from?
Pulmonary embolism (PE) (blood clot in the lungs)
Do you have any of these signs?
symptoms most commonly in one eye:
- immediate loss of vision or
- painless blurring of vision which can become a loss of vision.
What could you be suffering from?
Retinal vein thrombosis (blood clot in the eye)
Do you have any of these signs?
- chest pain or discomfort, pressure,
- heaviness
- sensation of squeezing or fullness in the chest, arm or below the breastbone
- fullness, indigestion or choking feeling
- upper body discomfort spreading out to the back, jaw, throat, arm and stomach
- sweating, nausea, vomiting or dizziness
- extreme weakness, anxiety, or shortness of breath
- rapid or irregular heartbeats.
What could you be suffering from?
Heart attack
Do you have any of these signs?
- sudden weakness or numbness of the face, arm or leg, especially on one side of the body
- sudden confusion, trouble speaking or understanding
- sudden trouble seeing in one or both eyes
- sudden trouble walking, dizziness, loss of balance or coordination
- sudden, severe or prolonged headache with no known cause
- loss of consciousness or fainting with or without seizure.
Sometimes the symptoms of a stroke can be brief with an almost immediate and full recovery, but you should still seek urgent medical attention as you may be at risk of another stroke.
What could you be suffering from?
Stroke
(blood clot in the brain)
Do you have any of these signs?
- swelling and slight blue discolouration of an extremity such as hands and feet
- severe pain in your stomach (acute abdomen)
What could you be suffering from?
Blood clots blocking other blood vessels
Blood clots in a vein
What can happen if a blood clot forms in a vein?
- The use of combined hormonal contraceptives has been connected with an increase in the risk of blood clots in the vein (venous thrombosis). However, these side effects are rare. Most frequently, they occur in the first year of use of a combined hormonal contraceptive.
- If a blood clot forms in a vein in the leg or foot it can cause a deep vein thrombosis (DVT)
- If a blood clot travels from the leg and lodges in the lung it can cause a pulmonary embolism
- Very rarely a clot may form in a vein in another organ such as the eye (retinal vein thrombosis).
When is the risk of developing a blood clot in a vein highest?
The risk of developing a blood clot in a vein is highest during the first year of taking the Pill for the first time. The risk may also be higher if you restart taking the Pill (the same product or a different product) after a break of 4 weeks or more.
After the first year, the risk gets smaller but is always slightly higher than if you were not using the Pill.
When you stop using Lizinna your risk of a blood clot returns to normal within a few weeks.
What is the risk of developing a blood clot?
The risk depends on your natural risk of VTE and the type of Pill you are taking.
The overall risk of a blood clot in the leg or lung (DVT or PE) with Lizinna is small.
- Out of 10,000 women who are not using any combined hormonal contraceptive and are not pregnant, about 2 will develop a blood clot in a year.
- Out of 10,000 women taking a Pill containing levonorgestrel or norethisterone, or norgestimate such as Lizinna, about 5-7 will develop a blood clot in a year.
- The risk of having a blood clot will vary according to your personal medical history (see “Factors that increase your risk of a blood clot” below).
Risk of developing a blood clot in a year
Women who are not using a combined hormonal Pill/patch/ring and are not pregnant About 2 out of 10,000 women
Women using a Pill containing levonorgestrel, norethisterone or norgestimate About 5-7 out of 10,000 women
Women using Lizinna About 5-7 out of 10,000 women
Factors that increase your risk of a blood clot in a vein
The risk of a blood clot with Lizinna is small but some conditions will increase the risk. Your risk is higher:
- if you are very overweight (body mass index or BMI over 30 kg/m2)
- if one of your immediate family has had a blood clot in the leg, lung or other organ at a young age (such as, below the age of about 50 years old). In this case you could have a hereditary blood clotting disorder
- if you need to have an operation or if you are off your feet for a long time because of an injury or illness, or you have your leg in a cast. The use of Lizinna may need to be stopped for several weeks before surgery or while you are less mobile. If you need to stop Lizinna ask your doctor when you can start using it again
- as you get older (particularly above about 35 years)
- if you gave birth less than a few weeks ago.
The risk of developing a blood clot increases the more conditions you have.
Air travel (for longer than 4 hours) may temporarily increase your risk of a blood clot, particularly if you have some of the other risk factors listed.
- It is important to tell your doctor if any of these risk factors apply to you, even if you are unsure. Your doctor may decide that Lizinna needs to be stopped.
If any of the above conditions change while you are using Lizinna, for example a close family member has a thrombosis for no known reason or you gain a lot of weight, tell your doctor.
Blood clots in an artery
What can happen if a blood clot forms in an artery?
Like a blood clot in a vein, a clot in an artery can cause serious problems. For example, it can cause a heart attack or a stroke.
Factors that increase your risk of a blood clot in an artery
It is important to note that the risk of a heart attack or stroke from using Lizinna is very small but can increase:
- with increasing age (particularly above about 35 years old)
- if you smoke. When using a Pill like Lizinna you are advised to stop smoking. If you are unable to stop smoking and are older than 35, your doctor may advise you to use a different type of contraceptive
- if you are overweight
- if you have high blood pressure
- if a member of your immediate family has had a heart attack or stroke at a young age (less than about 50). In this case you could also have a higher risk of having a heart attack or stroke
- if you or someone in your immediate family has a high level of fat in the blood (cholesterol or triglycerides)
- if you get migraines, especially migraines with aura
- if you have a problem with your heart (valve disorder, disturbance of the rhythm called atrial fibrillation)
- if you have diabetes.
If you have more than one of these conditions or if any of them are particularly severe the risk of developing a blood clot may be increased even more.
- Tell your doctor if any of these risk factors applies to you. If any of the above conditions change while you are using Lizinna, for example you start smoking, a close family member has a thrombosis for no known reason, or you gain a lot of weight, tell your doctor. Taking the Pill may add to these risks so Lizinna may not be suitable for you.
If you ever need to take another medicine at the same time as being on the Pill, always tell your doctor, pharmacist or dentist that you’re taking Lizinna. Also check the leaflets that come with all your medicines to see if they can be taken with hormonal contraceptives.
Some medicines can stop Lizinna from working properly – for example:
- some medicines used to treat epilepsy (such as topiramate, carbamazepine, phenytoin, fosphenytoin, oxcarbazepine, felbamate, primidone, eslicarbazepine acetate, rufinamide)
- bosentan (for high blood pressure in the blood vessels of the lungs)
- certain medicines for tuberculosis such as rifampicin and rifabutin
- anti-HIV medicines
- boceprevir and telaprevir (for treatment of Hepatitis C infections)
- aprepitant and fosaprepitant (for prevention of nausea and vomiting caused by certain cancer drug treatment)
- griseofulvin (for fungal infections)
- modafinil (for excessive daytime sleepiness)
- certain sedatives (called ‘barbiturates’)
- St. John’s Wort (a herbal remedy)
- metoclopramide (to increase movement through the gut)
- charcoal
- colesevelam (to treat high cholesterol levels)
- etoricoxib (to help with pain and inflammation of arthritis)
If you do need to take one of these medicines, Lizinna may not be suitable for you or you may need to use extra contraception for a while. Your doctor, pharmacist or dentist can tell you if this is necessary and for how long.
Lizinna can also affect other medicines- for example:
- ciclosporin (to prevent transplant rejection and for rheumatoid arthritis or some skin problems)
- lamotrigine (for epilepsy)
- prednisolone (a steroid to reduce inflammation)
- selegiline (for Parkinson’s disease)
- theophylline (for asthma, bronchitis and emphysema)
- tizanidine (used to relax muscles)
Talk to your doctor before having Lizinna if you are taking any of these medicines. They may have to change how much of these medicines you are taking.
Do not use Lizzina Tablets if you have hepatitis C and are taking the medicinal products containing ombitasvir/paritaprevir/ritonavir, dasabuvir, glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir, as these products may cause increases in liver function blood test results (increase in ALT liver enzyme). Your doctor will prescribe another type of contraceptive prior to start of the treatment with these medicinal products. Lizzina Tablets can be restarted approximately 2 weeks after completion of this treatment. See section 2.3 ‘Do not take Lizzina if any of the following applies to you:’
