miscarriage and of serious birth defects in babies whose mothers took the
medicine during pregnancy. Doctors may prescribe these medicines only for a
female who is not pregnant and who does not intend to become pregnant while
taking the medicine. You must also use two methods of birth control and have
pregnancy tests on a regular basis while using this medicine.
The FDA has announced that the companies that make
isotretinoin have a program to register doctors who prescribe isotretinoin and
the people who take it. The program is to ensure that women taking this drug
understand the risk of birth defects, take precautions to avoid pregnancy, and
know what to do if they become pregnant. If your doctor suggests that you take
isotretinoin, you must be registered with iPLEDGE in order to get the drug. You
can get more information and register at www.ipledgeprogram.com or by telephone
at 1-866-495-0654 (toll-free).
