Drug
Isotretinoin
Pronounced
"eye-so-tret-ih-NO-in"
Uses
This medication is used to treat severe cystic acne (also known as nodular acne) that has not responded to other treatment (such as benzoyl peroxide or clindamycin applied to the skin or tetracycline or minocycline taken by mouth). It belongs to a class of drugs known as retinoids. It works by decreasing facial oil (sebum) production. High amounts of sebum can lead to severe acne. If left untreated, severe acne may cause permanent scarring.
Warning
Women who are pregnant must not use isotretinoin. Women must avoid becoming pregnant while taking this medication. Serious (sometimes fatal) birth defects, miscarriages, and premature births have occurred when this drug has been used during pregnancy.
For female patients, two effective forms of birth control (or complete avoidance of sexual intercourse) must be used for 1 month before starting isotretinoin, during use, and for 1 month after stopping this drug. You must also have monthly pregnancy-avoidance counseling from your doctor. Do not use "minipills" for birth control (non-estrogen-containing pills) since they may not work as well with isotretinoin. If you are late in having your period, or if you have sexual intercourse at any time without using two effective forms of birth control, stop taking this medication and contact your doctor right away. (See also the Precautions section.)
