Before Using This Medicine
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 is not recommended 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:

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.

Continuing dryness of the mouth may increase the chance of developing dental disease, including tooth decay, gum disease, and fungus infections.
