Generic name: isotretinoin. A prescription-only drug derived from vitamin A, and which is taken orally. It essentially stops the oil production in sebaceous glands (the oil-producing structures of the skin) and literally shrinks these glands to the size of a baby's. This prevents sebum (oil) from clogging the hair follicle, mixing with dead skin cells, and rupturing the follicle wall to create an environment where a bacterium (Propionibacterium acnes) can thrive, which can result in pimples or cysts. Normal oil production resumes when treatment is completed, and the sebaceous glands slowly begin to grow larger again, but rarely as large as they were before treatment. "Because of its relatively rapid onset of action and its high efficacy with reducing more than 90% of the most severe [acne] inflammatory lesions, Accutane has a role as an effective treatment in patients with severe acne that is recalcitrant to other therapies".
However, Accutane is controversial for many reasons, principally because of its most insidious side effect: It has been proven to cause severe birth defects in nearly 90% of the babies born to women who were pregnant while taking it. Other commonly reported, although temporary, side effects of Accutane include dry skin and lips, mild nosebleeds (your nose can get really dry for the first few days), hair loss, aches and pains, itching, rash, fragile skin, increased sensitivity to the sun, headaches, and peeling palms and hands. More serious, although much less common, side effects include severe headaches, nausea, vomiting, blurred vision, changes in mood, depression, severe stomach pain, diarrhea, decreased night vision, bowel problems, persistent dryness of eyes, calcium deposits in tendons, an increase in cholesterol levels, and yellowing of the skin.
