Pregnancy Prevention Programme
This medicinal product is TERATOGENIC.
Acitretin is contraindicated in women of childbearing potential unless all of the following conditions of the Pregnancy Prevention Programme are met:
• Acitretin is indicated for (see section 4.1 “Therapeutic indications”):
o Extensive and severe refractory forms of psoriasis;
o Pustulous psoriasis of the hands and feet;
o Sever congenital ichtyosisand ichthyosiform dermatitis;
o Lichten ruber planus of skin and mucous membranes;
o Other severe and refractory forms of dermatitis characterised by dyskeratosis and/or hyperkeratosis.
• The potential for pregnancy must be assessed for all female patients.
• She understands the teratogenic risk.
• She understands the need for rigorous follow-up on a monthly basis.
• She understands and accepts the need for effective contraception, without interruption, 1 month before starting treatment, throughout the entire duration of treatment and for 3 years after the end of treatment. At least one highly effective method of contraception (i.e. a user-independent form) or two complementary user-dependent forms of contraception should be used.
• Individual circumstances should be evaluated in each case, when choosing the contraception method, involving the patient in the discussion, to guarantee her engagement and compliance with the chosen measures.
• Even if she has amenorrhea she must follow all the advice on effective contraception.
• She is informed and understands the potential consequences of pregnancy and the need to rapidly consult if there is a risk of pregnancy or if she might be pregnant.
• She understands the need and accepts to undergo regular pregnancy testing before, ideally monthly during treatment and periodically with 1-3 monthly intervals for a period of 3 years after stopping treatment.
• She has acknowledged that she has understood the hazards and necessary precautions associated with the use of acitretin.
These conditions also concern women who are not currently sexually active unless the prescriber considers that there are compelling reasons to indicate that there is no risk of pregnancy.
The prescriber must ensure that:
• The patient complies with the conditions for pregnancy prevention as listed above, including confirmation that she has an adequate level of understanding.
• The patient has acknowledged the aforementioned conditions.
• The patient understands that she must consistently and correctly use one highly effective method of contraception (i.e. a user-independent form) or two complementary user-dependent forms of contraception, for at least 1 month prior to starting treatment and is continuing to use effective contraception throughout the treatment period and for at least 3 years after cessation of treatment.
• Negative pregnancy test results have been obtained before, during and periodically with 1-3 monthly intervals for a period of 3 years after stopping treatment. The dates and results of pregnancy tests should be documented.
If pregnancy occurs in a woman treated with acitretin, treatment must be stopped and the patient should be referred to a physician specialised or experienced in teratology for evaluation and advice.
If pregnancy occurs after stopping treatment there remains a risk of severe and serious malformation of the foetus. This risk persists until the product has been completely eliminated, which is within 3 years following the end of treatment.
Contraception
Female patients must be provided with comprehensive information on pregnancy prevention and should be referred for contraceptive advice if they are not using effective contraception. If the prescribing physician is not in a position to provide such information the patient should be referred to the relevant healthcare professional
As a minimum requirement, female patients of childbearing potential must use at least one highly effective method of contraception (i.e. a user-independent form), or two complementary user-dependent forms of contraception. Contraception should be used for at least 1 month prior to starting treatment, throughout treatment and continue for at least 3 years after stopping treatment with acitretin, even in patients with amenorrhea.
Individual circumstances should be evaluated in each case, when choosing the contraception method involving the patient in the discussion, to guarantee her engagement and compliance with the chosen measures.
Pregnancy testing
According to local practice, medically supervised pregnancy tests with a minimum sensitivity of 25mUI/mL are recommended to be performed, as follows.
Prior to starting therapy
At least one month after the patient has started using contraception, and shortly (preferably a few days) prior to the first prescription, the patient should undergo a medically supervised pregnancy test. This test should ensure the patient is not pregnant when she starts treatment with acitretin.
Follow-up visits
Follow-up visits should be arranged at regular intervals, ideally monthly. The need for repeated medically supervised pregnancy tests every month should be determined according to local practice including consideration of the patient's sexual activity, recent menstrual history (abnormal menses, missed periods or amenorrhea) and method of contraception. Where indicated, follow-up pregnancy tests should be performed on the day of the prescribing visit or in the 3 days prior to the visit to the prescriber.
End of treatment
Women should undergo pregnancy test periodically with 1-3 monthly intervals for a period of 3 years after stopping treatment.
Prescribing and dispensing restrictions
For women of childbearing potential, the prescription duration of this medicine should ideally be limited to 30 days in order to support regular follow up, including pregnancy testing and monitoring. Ideally, pregnancy testing, issuing a prescription and dispensing of this medicine should occur on the same day.
This monthly follow-up will allow ensuring that regular pregnancy testing and monitoring is performed and that the patient is not pregnant before receiving the next cycle of medication.
Male patients
The available data suggest that the level of maternal exposure from the semen of the patients receiving this medicine is not of a sufficient magnitude to be associated with the teratogenic effects of acitretin. Male patients should be reminded that they must not share their medication with anyone, particularly not females.
Additional precautions
Patients should be instructed never to give this medicinal product to another person and to return any unused capsules to their pharmacist at the end of treatment.
Patients should not donate blood during therapy and for 3 years following discontinuation of acitretin because of the potential risk to the foetus of a pregnant transfusion recipient.
Educational material
In order to assist prescribers, pharmacists and patients in avoiding foetal exposure to acitretin the Marketing Authorisation Holder will provide educational material to reinforce the warnings about the teratogenicity of acitretin, to provide advice on contraception before therapy is started and to provide guidance on the need for pregnancy testing.
Full patient information about the teratogenic risk and the strict pregnancy prevention measures as specified in the Pregnancy Prevention Programme should be given by the physician to all patients, both male and female.
Psychiatric disorders
Depression, depression aggravated, anxiety, mood alterations and psychotic disorder have been reported in patients treated with systemic retinoids, including acitretin. Particular care should be taken in patients with a history of depression. Patients should be monitored for signs of depression and referred for appropriate treatment if necessary. Awareness by family or friends may be useful to detect mental health deterioration.
Other warnings
Clinical evidence has shown that etretinate can be formed with concurrent ingestion of acitretin and alcohol. Etretinate is highly teratogenic and has a longer half-life (approximately 120 days) than acitretin. Women of childbearing age must therefore not consume alcohol (in drinks, food or medicines) during treatment with acitretin and for 2 months after cessation of acitretin therapy. Contraceptive measures and pregnancy tests must also be taken for 3 years after completion of acitretin treatment (see section 4.6 and 5.2).
Women of childbearing potential must not receive blood from patients being treated with acitretin. Donation of blood by a patient being treated with acitretin is prohibited during and for 3 years after completion of treatment with acitretin.
Due to the risk of foetal malformations, the medicine must not be passed on to other people. Unused or expired products should be returned to a pharmacy for disposal.
In view of possible effects on liver function, this must be monitored regularly during treatment. Hepatic function should be checked before starting treatment with Acitretin, every 1 - 2 weeks for the first 2 months after commencement and then every 3 months during treatment. If abnormal results are obtained, weekly checks should be instituted. If hepatic function fails to return to normal or deteriorates further, Acitretin must be withdrawn. In such cases it is advisable to continue monitoring hepatic function for at least 3 months.
Serum cholesterol and serum triglycerides (fasting values) must be monitored before starting treatment, one month after the commencement and then every 3 months during treatment. Acitretin treatment should be discontinued in case of uncontrolled levels of hypertriglyceridemia or if symptoms of pancreatitis occur.
In diabetic patients, retinoids can alter glucose tolerance. Blood sugar levels should therefore be checked more frequently than usual at the beginning of the treatment period.
Before and during long-term therapy, x-rays (e.g. of the vertebral column, long bones, including ankles and wrists) must be taken at regular intervals (every year) in view of possible ossification abnormalities (see section 4.8). In the event of hyperostosis, the discontinuation of therapy must be discussed with the patient. The risks must be carefully weighed against the therapeutic benefit to be expected.
Since there have been occasional reports of bone changes in children, including premature epiphyseal closure, fractures, skeletal hyperostosis and extraosseous calcification after long-term treatment with etretinate, these effects may be expected with its active metabolite acitretin. Acitretin therapy in children is not, therefore, recommended unless, in the opinion of the physician, the benefits significantly outweigh the risks and all other alternative treatments have failed. If, in exceptional circumstances, such therapy is undertaken the child should be regularly monitored for any abnormalities of musculo-skeletal development and growth. Any symptoms that suggest possible bone changes (restricted mobility, bone pain) should be carefully investigated. As soon as the medical condition allows, the use of acitretin should be interrupted.
The dosage should be based on bodyweight (b.w.). An initial daily dose of 0.5 mg acitretin per kg b.w. is recommended. Higher doses up to 1 mg acitretin per kg b.w. per day may be necessary for a limited period in some cases. The maximum dose of 35 mg acitretin per day should not be exceeded.
The fixed-dose capsule formulations of 10 and 25 mg may not provide sufficient flexibility to cover the proposed paediatric dosing schedule per kg b.w. In this case preparation of a suitable dosage form (e.g. powders or capsules) made of the capsule content of Acitretin by qualified pharmaceutical personnel in a public or hospital pharmacy is suggested.
The mean maintenance dose lies at 0.1 mg acitretin per kg b.w. per day. The maintenance dose should be kept as low as possible and should generally not exceed 0.2 mg acitretin per kg b.w. per day (dosing every other day may be considered).
The effects of UV light are enhanced by retinoid therapy, therefore patients should avoid excessive exposure to sunlight and the unsupervised use of sun lamps.
Decreased night vision has been reported with acitretin therapy. Patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night. Visual problems should be carefully monitored (see sections 4.7 and 4.8).
Wearing of contact lenses might become impossible due to dryness of the eyes. Patients who wear contact lenses should be excluded from treatment or wear glasses throughout the treatment period.
Very rare cases of Capillary Leak Syndrome / retinoic acid syndrome have been reported from world-wide post marketing experience.
Very rare cases of Exfoliative dermatitis have been reported from world-wide post marketing experience.
This medicine contains less than 1mmol sodium (23mg) per tablet, that is to say essentially “sodium-free”.
