What is Accutane?

Accutane is a form of vitamin A. It reduces the amount of oil released by oil glands in your skin, and helps your skin renew itself more quickly.

Accutane is used to treat severe nodular acne that has not responded to other treatments, including antibiotics.

Accutane is available only from a certified pharmacy under a special program called iPLEDGE.


Accutane in just a single dose can cause severe birth defects or death of a baby. Never use this medicine if you are pregnant or able to become pregnant.

You must have a negative pregnancy test before taking Accutane. You will also be required to use two forms of birth control to prevent pregnancy while taking this medicine.

Women of child-bearing potential must agree in writing to use two specific forms of birth control and have regular pregnancy tests before, during, and after taking Accutane. Stop using Accutane and call your doctor at once if you think you might be pregnant.

Accutane is available only under a special program called iPLEDGE. It is dangerous to try and purchase this medicine on the Internet or from vendors outside of the United States.

Do not take vitamin supplements containing vitamin A while you are taking Accutane. Do not donate blood while taking Accutane and for at least 30 days after you stop taking it.

Before taking this medicine

Accutane can cause miscarriage, premature birth, severe birth defects, or death of a baby if the mother takes this medicine at the time of conception or during pregnancy. Even one dose of isotretinoin can cause major birth defects of the baby's ears, eyes, face, skull, heart, and brain. Never use Accutane if you are pregnant or able to become pregnant.

For Women: Unless you have had your uterus and ovaries removed (total hysterectomy) or have been in menopause for at least 12 months in a row, you are considered to be able to get pregnant. You must have 2 negative pregnancy tests before you start taking Accutane, before each prescription is refilled, right after you take your last dose, and again 30 days later. All pregnancy testing is required by the iPLEDGE program.

You must agree in writing to use two specific forms of birth control beginning 30 days before you start taking Accutane and ending 30 days after your last dose. Both a primary and a secondary form of birth control must be used together.

Primary forms of birth control include:

Secondary forms of birth control include:

Stop using Accutane and call your doctor at once if you have unprotected sex, if you quit using birth control, if your period is late, or if you think you might be pregnant. If you get pregnant while taking isotretinoin, call the iPLEDGE pregnancy registry at 1-866-495-0654.

Not having sexual intercourse (abstinence) is the most effective method of preventing pregnancy.
