Important Safety Information for Acitretin Capsules:

What is the most important information I should know about acitretin capsules?
Acitretin capsules can cause serious side effects, including:

• Severe birth defects. If you are a female who can get pregnant, you should use acitretin capsules only if:
• you are not pregnant now
• you can avoid becoming pregnant while taking acitretin capsules and for at least 3 years after stopping acitretin capsules and
• other medicines do not work for your severe psoriasis or you cannot use other psoriasis medicines

• Liver problems, including abnormal liver function tests and inflammation of your liver (hepatitis). Your prescriber should do blood tests to check how your liver is working before you start taking and during treatment with acitretin capsules. Stop taking acitretin capsules and call your prescriber right away if you have any of the following signs or symptoms of a serious liver problem:
• yellowing of your skin or the whites of your eyes
• nausea and vomiting
• loss of appetite
• dark urine

• You must not take acitretin capsules if you are pregnant or might become pregnant during treatment or at any time for at least 3 years after you stop treatment, because acitretin capsules can cause severe birth defects.
• You must use 2 effective forms of birth control (contraception) at the same time while you are taking acitretin capsules. You must use birth control for at least 1 month before you start taking acitretin capsules, during treatment, and for at least 3 years after you stop treatment.
  • Avoid progestin-only birth control pills ("minipills"). This type of birth control pill may not work while you take acitretin capsules. Ask your prescriber if you are not sure what type of pills you are using.

• During treatment and for 2 months after you stop acitretin capsules, you must avoid drinks, foods, and all medicines that contain alcohol. This includes over-the-counter products that contain alcohol. Avoiding alcohol is very important because alcohol changes acitretin capsules into a drug that may take longer than 3 years to leave your body.
• You and your prescriber must be sure you are not pregnant before you start acitretin capsules. Do not start acitretin capsules until you have negative results from 2 pregnancy tests.
• After you start taking acitretin capsules, you must have a pregnancy test repeated each month that you are on treatment. You must have a pregnancy test repeated every 3 months for at least 3 years after you stop taking acitretin capsules to make sure that you are not pregnant.

• Do not take acitretin capsules if you are breastfeeding. Acitretin can pass into your milk and may harm your baby. You will need to choose either to breastfeed or to take acitretin capsules, but not both.
• You should receive the MyMAC brochure from your prescriber. The brochure contains information about preventing pregnancy, birth control options, side effects, and the importance of avoiding products containing alcohol.

It is very important to stop taking acitretin capsules and call your prescriber right away if you develop such problems.
• visual changes, frequent urination, great thirst, or hunger. These can be signs of high blood sugar.
• blood vessel problems. Acitretin capsules can cause fluid to leak out of your blood vessels into your body tissues. Call your prescriber right away if you have any of the following symptoms: sudden swelling in one part of your body or all over your body, weight gain, fever, lightheadedness or feeling faint, or muscle aches. If this happens, your prescriber will tell you to stop taking acitretin capsules.

• dry eyes. Acitretin capsules may dry your eyes. Wearing contact lenses may be uncomfortable during and after treatment with acitretin capsules because of the dry feeling in your eyes. If this happens, remove your contact lenses and call your prescriber.
• rise in blood fats (lipids). Acitretin capsules can cause your blood fats (lipids) to rise. Most of the time this is not serious. But sometimes the increase can become a serious problem (see information under "Serious side effects"). You should have blood tests as directed by your prescriber.

Psoriasis gets worse for some patients when they first start treatment with acitretin capsules. Some patients have more redness or itching. If this happens, tell your prescriber.

These are not all the possible side effects of acitretin capsules. For more information, ask your prescriber or pharmacist.

What else should I avoid while taking acitretin capsules?

• Avoid dietary supplements containing vitamin A. Acitretin capsules are related to vitamin A. Therefore, do not take supplements containing vitamin A because they may add to the unwanted effects of acitretin capsules. Check with your prescriber or pharmacist if you have any questions about vitamin supplements.
