Acitretin (a-si-TRE-tin) is used to help relieve and control severe skin disorders, such as severe psoriasis. It works by allowing normal growth and development of the skin. Acitretin may continue to work after you stop taking it, but usually after a time, the skin condition returns and you may need to begin taking it again.

Acitretin must not be used to treat women who are able to bear children unless other forms of treatment have been tried first and failed. Acitretin must not be taken during pregnancy because it causes birth defects in humans. If you are able to bear children, it is very important that you read, understand, and follow the pregnancy warnings for acitretin .

You must take important precautions while taking acitretin and continue with them for a period of time after you stop taking the medicine . The precautions are:

• Women should not become pregnant and should use two methods of very effective birth control. The birth control methods should begin 1 month before starting the medicine and continue for at least 2 or 3 years after discontinuing the medicine or as directed by your doctor.
• Men and women should not donate blood for transfusion purposes during treatment and for 2 or 3 years after discontinuing the medicine or as directed by your doctor.
• Men and women should not drink alcohol during treatment and for 2 months after discontinuing the medicine.

If you do not think these precautions are reasonable, you should discuss this with your doctor before starting to take this medicine.

This medicine is available only with your doctor's prescription, in the following dosage form(s):

Oral
• Capsules (U.S. and Canada)

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For acitretin, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual reaction to acitretin, etretinate, isotretinoin, tretinoin, or vitamin A–like preparations, including vitamin A supplements. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Diet—Make certain your health care provider knows if you are on any special diet, such as a low-sodium, low-cholesterol, or low-sugar diet. Discuss with your doctor how often you drink alcohol, even if it is only an occasional drink.

Pregnancy—Acitretin must not be taken during pregnancy. It has been shown to cause serious birth defects and other problems in humans.

Before taking this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant. Beginning at least 1 month before you start to take acitretin, you should plan on using two effective forms of birth control to prevent pregnancy. In addition, since it is not known how long pregnancy should be avoided after treatment stops, you should plan not to become pregnant for at least 2 or 3 years after you stop taking acitretin or as directed by your doctor. If you become pregnant, stop taking the medicine and tell your doctor.

Breast-feeding—It is not known whether acitretin passes into the breast milk. However, use of acitretin should not be used during breast-feeding because it may cause unwanted effects in nursing babies. You also should plan not to breast-feed for at least 2 or 3 years after you stop taking acitretin.

Children—This medicine has been tested in some children and has been shown not to cause different side effects or problems in children than it does in adults. However, children may be more sensitive to some of the medicine's effect on bones, which may prevent normal bone growth during puberty. This can cause them to grow up to be shorter adults than expected. Therefore, it is especially important that you discuss with the child's doctor the good that this medicine may do as well as the risks of using it.

Older adults—This medicine has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults. However, some older patients may have higher levels of the medicine in the blood stream as compared to younger adults, and they may be more sensitive to its effects. This may increase their chance of developing side effects during treatment.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together, even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking acitretin, it is especially important that your health care professional know if you are taking any of the following:

• Alcoholic beverages—Drinking alcohol may convert acitretin to a much longer-acting product that can stay in the body 60 times longer than acitretin does. This may result in a greater chance of developing side effects for months or years, depending on how much and how often one drinks. This unusual effect can occur even after you stop taking acitretin, especially for the first 2 months after you stop taking this medicine

• Cyclosporine (e.g., Sandimmune or Neoral) or
• Phenytoin (e.g., Dilantin)—Acitretin may increase the effects of this medicine

• Etretinate (e.g., Tegison) or
• Isotretinoin (e.g., Accutane) or
• Tretinoin (oral) (e.g., Vesanoid) or
• Tretinoin (topical) (e.g., Avita, Renova, or Retin A) or
• Vitamin A, including vitamin supplements—Etretinate, isotretinoin, and tretinoin are not used together with acitretin; problems in skin, vision, and bone may be more likely to occur when they are used at the same time. If vitamin A is taken with acitretin, the dose of vitamin A should not exceed the minimum recommended daily allowance (RDA)

• Methotrexate (e.g., Rheumatrex, Trexall)—Should not be used with acitretin

• Oral contraceptives, progestin-only or “mini pills” (birth control pills) (e.g., Micronor, Nor-QD, Ovrette)—Acitretin may prevent progestin-only oral contraceptives from working properly and may result in an unplanned pregnancy. This does not occur with oral contraceptives containing both estrogens and progestins

• Tetracyclines (demeclocycline [e.g., Declomycin], doxycycline [e.g., Doxycin] minocycline [e.g., Minocin] oxytetracycline [e.g., Terramycin] tetracycline [e.g., Symycin])—Should not be used with acitretin

Other medical problems—The presence of other medical problems may affect the use of acitretin. Make sure you tell your doctor if you have any other medical problems, especially:

• Diabetes mellitus (sugar diabetes) or
• High cholesterol or triglycerides, uncontrollable (or history of) or
• Inflammation of pancreas (or history of)—Acitretin may make these conditions worse or increase cholesterol or triglyceride problems

• Hypervitaminosis A (or history of)—If you have past or current problems with toxic symptoms from vitamin A, acitretin may increase the chance that they will occur again

• Kidney disease, severe or
• Liver disease, severe—May cause acitretin to stay in the body for a longer period of time and increase the chance of side effects

Patient information is usually provided with acitretin. Read it carefully before using this medicine.

Take acitretin with a main meal or with a glass of milk.

For women— This medicine may cause birth defects . To make sure you are not pregnant before beginning treatment, your doctor will ask you to:

• Use two effective forms of birth control (contraception) for at least 1 month before beginning treatment.
• Report when your menstrual periods are normal .
• Take a pregnancy test within 1 week before beginning the treatment to make sure you are not pregnant.
• Begin your acitretin treatment on Day 2 or Day 3 of your next menstrual period.
• Sign a paper to show that you understand the importance of not becoming pregnant for at least 2 to 3 years after you stop taking this medicine, according to the advice of your doctor.

Using two effective forms of birth control for at least 2 or 3 years after you stop taking acitretin, according to the advice of your doctor, is very important to help prevent an unplanned pregnancy. If you do not think this is reasonable, you should discuss this with your doctor before you start taking this medicine .

Dosing—

Take acitretin with food. Taking with food is important for getting the right amount of medicine out of your stomach.

The dose of acitretin will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of acitretin. If your dose is different, do not change it unless your doctor tells you to do so.

It is important that you do not share this medicine with anyone else because of the risk of birth defects and other serious side effects.

The number of tablets that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are taking acitretin.

• For oral dosage form (tablets):
  • For severe psoriasis:
    • Adults—25 to 50 milligrams (mg) a day as a single dose. After four weeks, your doctor may increase your dose depending on how well this medicine is working for you
    • Children—Use and dose must be determined by your doctor.
  • For other severe skin disorders (such as bullous or nonbullous erythroderma, lamellar ichthyoses, and keratosis follicularis):
    • Adults—25 milligrams (mg) a day. After four weeks, a dose of 10 to 75 mg a day is used.
    • Children—Use and dose must be determined by your doctor.

Missed dose—

Take the missed dose as soon as possible. However, if you do not remember the missed dose until the next day, skip the missed dose and go back to your regular dosing schedule. Do not double doses. If you have any questions about this, check with your doctor.

Storage—

To store this medicine:

• Keep out of the reach of children.
• Store away from heat and direct light.
• Do not store in the bathroom, near the kitchen sink, or in other damp places. Heat or moisture may cause the medicine to break down.
• Do not keep outdated medicine or medicine no longer needed. Be sure that any discarded medicine is out of the reach of children.

It is important that your doctor check your progress at regular visits while you are taking this medicine. If your condition has improved and you are no longer taking acitretin, your progress must still be checked. This is especially important for children or elderly patients, who may be more sensitive to the effects of this medicine, and for women who want to become pregnant after they stop taking the medicine.

It is important that you check with your doctor before taking any medicines including vitamins, herbal products or over-the-counter (OTC) medicines. Some of these medicines or nutritional supplements (e.g., St. John's wort) may make your birth control pills not work.

Your skin condition may improve or get worse during the first 3 weeks of treatment and you also may notice some skin irritation from the medicine. With continued use, the expected skin irritation will lessen after a few weeks. Check with your health care professional any time skin irritation becomes severe or if your skin condition does not improve within 8 to 12 weeks.

Do not drink alcohol while taking this medicine or for at least 2 months after discontinuing treatment.

• Drinking alcohol can change the medicine in the body to a product that stays in your body for an extended period of time. This can increase your chance of developing side effects for a longer period of time than if you hadn't consumed alcohol.
• If a woman consumes alcohol during acitretin treatment, she should consider delaying a pregnancy for longer than 2 or 3 years or as directed by her doctor.

Do not donate blood during treatment with acitretin, for 2 or 3 years following treatment, or as otherwise directed by your doctor . Although problems resulting from a blood transfusion are not likely, this precaution prevents the possibility that your blood would be used in pregnant women.

Acitretin can cause dryness of the eyes, blur your vision, or cause other vision problems. Be aware that while using acitretin you may see a sudden decrease in your night vision (ability to see before the sun rises or after the sun goes down). Also, acitretin may cause your eyes to be more sensitive to light, including sunlight, than they are normally. These effects can make certain activities dangerous, such as driving or operating machines.

Check with your doctor if you experience any vision or eye problem. Wearing contact lenses may become uncomfortable. Your doctor may suggest using artificial tears to keep your eyes from getting too dry.

Acitretin may cause dryness of the mouth, nose, and throat. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of developing dental disease, including tooth decay, gum disease, and fungus infections.

Avoid overexposing your skin to wind, cold weather, and sunlight, even on cloudy days. Your skin will be more prone to sunburn, dryness, or irritation, especially during the first 2 or 3 weeks. However, you should not stop taking this medicine, unless the skin irritation becomes too severe. For best results:

• Wear sunglasses that can block ultraviolet (UV) light. Ordinary sunglasses may not protect your eyes.
• Regularly use sunscreen or sunblocking lotions with a sun protection factor (SPF) of at least 15.
• Wear protective clothing and hats and stay out of direct sunlight, especially between the hours of 10 a.m. and 3 p.m.
• Apply creams, lotions, or moisturizers often. Your health care professional can help you choose the right skin products for you to reduce skin dryness and irritation.
• Do not use an artificial light, such as a sunlamp, unless directed otherwise by your doctor.

Unless your doctor tells you otherwise, it is especially important to avoid using the following skin products:

• Any topical acne product or skin product containing a peeling agent (such as benzoyl peroxide, resorcinol, salicylic acid, or sulfur).
• Hair products that are irritating, such as permanents or hair removal products.
• Skin products that cause sensitivity to the sun, such as those containing spices or limes.
• Skin products containing a large amount of alcohol, such as astringents, shaving creams, or after-shave lotions.
• Skin products that are too drying or abrasive, such as some cosmetics, soaps, or skin cleansers.

Using these products when taking acitretin may cause mild to severe irritation of the skin.

Do not take doses of vitamin A or any vitamin supplement containing vitamin A that exceeds the minimum recommended allowance (RDA) while you are taking this medicine. To do so may increase the chance of developing side effects.
