acitretin

What is the most important information I should know about acitretin?

You must use effective birth control to avoid getting pregnant while taking acitretin and for at least 3 years after your last dose. You will need pregnancy tests at regular intervals to make sure you are not pregnant.

What is acitretin?

Acitretin is a retinoid, which is a form of vitamin A.

Acitretin is used to treat severe psoriasis in adults. Acitretin is not a cure for psoriasis, and you may relapse after you stop taking this medication.

Acitretin may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking acitretin?

• you have severe liver disease or severe kidney disease;
• you have high levels of triglycerides (a type of fat) in your blood;
• you are pregnant or breast-feeding;
• you are also using methotrexate; or
• you also use a tetracycline antibiotic (such as demeclocycline, doxycycline, minocycline, tetracycline, and others).

Acitretin is available to women only under an agreement that you will use approved birth control methods and undergo required pregnancy testing while taking this medicine and for at least 3 years after your last dose.

For women taking acitretin who have not had a hysterectomy or have not gone completely through menopause: Before you start taking acitretin you must have 2 negative pregnancy tests (when your doctor first prescribes acitretin, and again during the first 5 days of your menstrual period just before you start taking this medicine). You will also need pregnancy tests every month while you are taking acitretin, and every 3 months for at least 3 years after your last dose.

The first birth control method should include one of the following forms:

• birth control pills (but not the "mini-pill");
• an intrauterine device (IUD);
• birth control shots, inserts, skin patches, or implants;
• a tubal ligation; or
• your male partner's vasectomy.

The second birth control method should include one of the following forms:

• a diaphragm or cervical cap used with a spermicide;
• a latex condom used with or without a spermicide; or
• a vaginal sponge that contains a spermicide.

Start using both forms of birth control at least 1 month before you start taking acitretin. Continue using both forms while you are taking acitretin and for at least 3 years after your last dose. Use both forms of birth control together every time you have sex.

If you are not menstruating, you should have a pregnancy test at least 11 days after you last had sex without using 2 effective forms of birth control.

To make sure acitretin is safe for you, tell your doctor if you have ever had:

• phototherapy;
• kidney or liver disease;
• heart disease;
• high cholesterol or triglycerides (a type of fat in the blood);
• diabetes (you may need to check your blood sugar more often);
• a habit of drinking large amounts of alcohol;
• depression; or
• if you have ever used a medicine called etretinate (Tegison, Tigason).

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

While using acitretin, you may need frequent blood tests. If you use this medicine long-term, you may need additional medical tests, including x-rays.

What happens if I miss a dose?
