Uses for acitretin
Acitretin is used to treat severe skin disorders, such as psoriasis. It works by allowing normal growth and development of the skin. Acitretin will continue to work after you stop taking it, but after a time, the skin condition returns and you may need to take 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 have 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.
Acitretin is available only with your doctor's prescription.
Before using acitretin
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:
Tell your doctor if you have ever had any unusual or allergic reaction to acitretin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of acitretin in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of acitretin in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving acitretin.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Proper use of acitretin
It is very important that you take acitretin only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
Acitretin comes with a patient information form and Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions. You will be asked to sign a consent form before you starting taking acitretin to show that you understand the instructions.
You will be given information about the Do Your P.A.R.T. program, which is also called the Pregnancy Prevention Actively Required During and After Treatment program. This is important information about how to prevent pregnancy while you are using acitretin. Ask your doctor about this program if you have any questions.
Take acitretin with your main meal of the day.
For women—Acitretin may cause birth defects. To make sure that you are not pregnant before beginning treatment, your doctor will ask you to:
- Use two effective forms of birth control (contraception) together for at least 1 month before beginning treatment.
- Report when your menstrual periods are normal.
- Take a pregnancy test within 1 week before beginning 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 acitretin.
Women who are able to bear children must use two effective forms of birth control together for at least 2 to 3 years after they stop taking acitretin to help prevent an unplanned pregnancy. If you do not think this is reasonable or feel like you can not do this, talk to your doctor before you start taking acitretin.
You must not share acitretin with anyone else because of the risk for birth defects and other serious side effects.
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.
The amount of medicine 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 using the medicine.

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Precautions while using acitretin
It is important that your doctor check your progress at regular visits to make sure that acitretin is working properly. Blood tests may be needed to check for unwanted effects.
Using acitretin while you are pregnant can cause very serious birth defects. You must use 2 forms of birth control together for 1 month before starting acitretin, for the entire time that you are being treated with acitretin, and for 3 years after you take your last dose of acitretin. You will need to have 2 negative pregnancy tests to be sure that you are not pregnant before you start using acitretin. You will also need to have pregnancy tests every month during treatment, and every 3 months for 3 years after you stop taking the medicine. If you think you have become pregnant while using acitretin, call your doctor right away.
Do not use methotrexate (Rheumatrex®, Trexall®) or a tetracycline medicine to treat an infection (eg, doxycycline, minocycline, tetracycline, Minocin®, or Vibramycin®) while you are using acitretin. Using these medicines together may cause unwanted side effects.
Do not take vitamin A or any supplement containing vitamin A while you are using acitretin, unless otherwise directed by your doctor. To do so may increase the chance of side effects.
Your skin condition may improve or get worse during the first few 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 doctor if the skin irritation becomes worse or if your skin condition does not improve within 8 to 12 weeks.
Women who are able to bear children must avoid all forms of alcohol while they are taking acitretin and for 2 months after they stop. Do not eat foods, drink beverages, or take medicines that contain alcohol. Drinking alcohol will make the medicine remain in the body for an extended period of time and will increase the chance for side effects. If a woman consumes alcohol during acitretin treatment, she should consider delaying a pregnancy for longer than 2 to 3 years. Talk to your doctor if you have any questions about this.
Do not donate blood during treatment with acitretin, for 3 years following treatment, or as directed by your doctor. Women who are able to bear children must not receive blood containing the medicine.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Acitretin may cause bone or muscle problems, including joint pain, muscle pain or stiffness, or difficulty moving. You may get hurt more easily during rough sports. You may also heal more slowly.
Acitretin may cause blurred vision or a decrease in night vision (night blindness). The night blindness may occur suddenly. Do not drive or do anything else that could be dangerous if you are not able to see well. Check with your doctor right away if you have vision changes.
Acitretin may cause dry eyes. Wearing contact lenses may become uncomfortable while using acitretin. To help relieve dry eyes, check with your doctor about using a lubricating solution, such as artificial tears. If severe eye irritation or inflammation occurs, check with your doctor.
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 dry mouth continues 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 exposing 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. You should not stop taking acitretin, unless the skin irritation becomes too severe. Do not use a sunlamp or tanning bed. Use sunscreen or sunblock lotions with a sun protection factor (SPF) of at least 15 on a regular basis. Wear protective clothing and hats and stay out of direct sunlight, especially between the hours of 10 a.m. and 3 p.m.
Unless your doctor tells you otherwise, you should avoid skin products that can irritate the skin. Some examples are:
- Any topical acne product or skin product containing a peeling agent (eg, 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.
For diabetic patients:
- Acitretin may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests or if you have any questions, check with your doctor.
Pancreatitis may occur while you are using acitretin. Tell your doctor right away if you have sudden and severe stomach pain, chills, constipation, nausea, vomiting, fever, or lightheadedness.
Acitretin may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you or your caregiver notice any of these side effects, check with you doctor right away.
Call your doctor right away if you have a fever, cloudy urine, decrease or increase in the amount of urine, fainting or lightheadedness, nausea, stomach pain, or swelling of the hands, ankles, feet, or lower legs. These may be symptoms of a rare but serious condition called capillary leak syndrome.
Do not take other medicines without checking first with your doctor. This includes vitamins, herbal products, prescription or nonprescription (over-the-counter [OTC]) medicines. Some of these medicines or nutritional supplements (eg, St. John's wort) may make your birth control pills not work.
