Proper Use

Isotretinoin comes with a patient information form and medication guide. It is very important that you read and understand this information. Be sure to carefully follow these instructions and ask your doctor if you have any questions.

Women of reproductive age must sign up for a pregnancy risk program called iPLEDGE™ in order to receive their isotretinoin prescription each month. You can sign up on the internet (www.ipledge.com) or by telephone (1-866-495-0654). Be sure to ask your doctor if you have any questions about this program. It is very important that you understand and follow all of the requirements. You will not get another prescription unless you follow the instructions for the program.

Isotretinoin must not be taken by women of reproductive age unless two effective forms of contraception (birth control) have been used for at least 1 month before the beginning of treatment. Contraception must be continued during the period of treatment, which is up to 20 weeks, and for 1 month after isotretinoin is stopped. Be sure you have discussed this information with your doctor.

If you are a woman who is able to have children, you must have a pregnancy blood test within 1 week before beginning treatment with isotretinoin to make sure you are not pregnant. Treatment with isotretinoin will then be started within the week, on the second or third day of your next normal menstrual period. In addition, you must have a pregnancy blood test each month while you are taking this medicine and one month after treatment is completed.

Swallow the capsule whole, with food and a full glass (8 ounces) of water or other liquid. Do not break, crush, or chew the capsule.

It is very important that you take isotretinoin only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.

It is very important that you not share this medicine with anyone else because of the risk of birth defects and other serious side effects.
