For female patients:
Do not take acitretin if you are pregnant or plan to become pregnant within the next 3 years. Acitretin may harm the fetus. You should not begin taking acitretin until you have taken two pregnancy tests with negative results. You must use two acceptable forms of birth control for 1 month before you begin taking acitretin, during your treatment with acitretin, and for 3 years after treatment. Your doctor will tell you which methods of birth control are acceptable. You do not need to use two methods of birth control if you have had a hysterectomy (surgery to remove the womb), if your doctor tells you that you have finished menopause (change of life), or if you practice total sexual abstinence.
If you plan to use oral contraceptives (birth control pills) while taking acitretin, tell your doctor the name of the pill you will use. Acitretin interferes with the action of microdosed progestin ('minipill') oral contraceptives (Ovrette, Micronor, Nor-QD). Do not use this type of birth control while taking acitretin.
If you plan to use hormonal contraceptives (birth control pills, patches, implants, injections, and intrauterine devices), be sure to tell your doctor about all the medications, vitamins, and herbal supplements you are taking. Many medications interfere with the action of hormonal contraceptives. Do not take St. John's wort if you are using any type of hormonal contraceptive.
You will need to take pregnancy tests regularly while taking acitretin. Stop taking acitretin and call your doctor immediately if you become pregnant, miss a menstrual period, or have sex without using two forms of birth control. In some cases, your doctor can prescribe emergency contraception ('the morning after pill') to prevent pregnancy.
Do not consume foods, drinks, or prescription or nonprescription medications that contain alcohol while taking acitretin and for 2 months after treatment. Alcohol and acitretin combine to form a substance that remains in the blood for a long time and can harm the fetus. Read medication and food labels carefully and ask your doctor or pharmacist if you are not sure whether a medication contains alcohol.
Your doctor will give you a Patient Agreement/Informed Consent to read and sign before you begin treatment. Be sure to read this carefully and ask your doctor if you have any questions.
For male patients:
A small amount of acitretin is present in the semen of male patients who take this medication. It is not known whether this small amount of medication can harm the fetus. Talk to your doctor about the risks of taking this medication if your partner is pregnant or plans to become pregnant.
For male and female patients:
Do not donate blood while taking acitretin and for 3 years after treatment.
Acitretin may cause liver damage. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: upset stomach, extreme tiredness, unusual bruising or bleeding, lack of energy, loss of appetite, pain in the upper right part of the stomach, yellowing of the skin or eyes, dark urine, or flu-like symptoms.
WHY is this medicine prescribed?
Acitretin is used to treat severe psoriasis (abnormal growth of skin cells that causes red, thickened, or scaly skin). Acitretin is in a class of medications called retinoids. The way acitretin works is not known.
HOW should this medicine be used?
Acitretin comes as a capsule to take by mouth. It is usually taken once a day with the main meal. Take acitretin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acitretin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of acitretin and gradually increase your dose.
Acitretin controls psoriasis but does not cure it. It may take 2-3 months or longer before you feel the full benefit of acitretin. Your psoriasis may get worse during the first few months of treatment. This does not mean that acitretin will not work for you, but tell your doctor if this happens. Continue to take acitretin even if you feel well. Do not stop taking acitretin without talking to your doctor.
After you stop taking acitretin, your symptoms may come back. Tell your doctor if this happens. Do not use leftover acitretin to treat a new flare-up of psoriasis. A different medication or dose may be needed.
Are there OTHER USES for this medicine?
Acitretin is sometimes also used to treat Darier's disease (a type of skin disease); palmoplantar pustulosis (pus-filled blisters and red patches on the hands and feet); lichen sclerosus et atrophicus of the vulva (redness, scaling, and easy bleeding of the genital area in females); palmoplantar lichen nitidus (clusters of bumps on the hands and feet); and lichen planus (red, itchy bumps in various places on the body). It is also used to treat lamellar ichthyosis (scaly patches of skin that fall off the body); Sjogren-Larsson syndrome (dry, scaling skin, mental retardation, and trouble walking); and bullous and nonbullous ichthyosiform erythroderma (red, blistering, or peeling skin) in children. Talk to your doctor about the possible risks of using this drug for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
