Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional.

This medication contains a female hormone called progesterone. Progesterone is needed to prepare the lining of the uterus so it can receive a fertilized egg. Progesterone and other hormones help you become and stay pregnant. This medication is used to increase the level of progesterone in women taking fertility treatments because these treatments tend to decrease progesterone levels.
