Side Effects and Conditions Caused By Isotretinoin

Minor discomforts such as dry mouth or nose, dry eyes, dry skin, or itching usually go away as the body adjusts to the drug and do not require medical attention unless they continue or are bothersome.

Other side effects should be brought to a physician’s attention. These include:
•    burning, redness, or itching of the eyes
•    nosebleeds
•    signs of inflammation of the lips, such as peeling, burning, redness or pain

Bowel inflammation is not a common side effect, but it may occur. If any of the following signs of bowel inflammation occur, stop taking isotretinoin immediately and check with a physician:
•    pain in the abdomen
•    bleeding from the rectum
•    severe diarrhea

Conditions Caused By Benzoyl Peroxide and Tretinoin

The most common side effects of antiacne drugs applied to the skin are slight redness, dryness, peeling, and stinging, and a warm feeling to the skin. These problems usually go away as the body adjusts to the drug and do not require medical treatment.
Other side effects should be brought to a physician’s attention. Check with a physician as soon as possible if any of the following side effects occur:

•    blistering, crusting, or swelling of the skin
•    severe burning or redness of the skin>
•    darkening or lightening of the skin (This effect will eventually go away after treatment with an antiacne drug ends.)
•    skin rash

Other side effects are possible with any type of antiacne drug. Anyone who has unusual symptoms while using antiacne drugs should get in touch with his or her physician.
Interactions

Patients using antiacne drugs on their skin should tell their physicians if they are using any other prescription or nonprescription (over-the-counter) medicine that they apply to the skin in the same area as the antiacne drug.

Isotretinoin may interact with other medicines. When this happens, the effects of one or both drugs may change or the risk of side effects may be greater. Anyone who takes isotretinoin should let the physician know about all other medicines being used and should ask whether the possible interactions can interfere with drug therapy.

Among the drugs that may interact with isotretinoin are listed below:
•    Etretinate (Tegison), used to treat severe psoriasis. Using this medicine with isotretinoin increases side effects.
•    Tretinoin (Retin-A, Renova). Using this medicine with isotretinoin increases side effects.
•    Vitamin A or any medicine containing vitamin A. Using any vitamin A preparations with isotretinoin increases side effects. Do not take vitamin supplements containing vitamin A while taking isotretinoin.
•    Tetracyclines (used to treat infections). Using these medicines with isotretinoin increases the chance of swelling of the brain. Make sure the physician knows if tetracycline is being used to treat acne or another infection.

Parental Concerns

Acne comes at a difficult time, the adolescent years. While mild acne can be treated with over-the-counter medications, more severe acne needs medical attention. Experts advise against a wait-and-see attitude. Treatment options can help control acne and avoid scarring.

Isotretinoin can cause serious birth defects, including mental retardation and physical deformities. This medicine should not be used during pregnancy. Sexually active adolescent females who are able to bear children should not use isotretinoin unless they have very severe acne that has not cleared up with the use of other antiacne drugs. In addition, acne treatments that can dry the skin should be used with caution by people with skin of color.
