Cyclogest 400 mg, 1 x 15 Pessaries
Why is this medication prescribed?
Progesterone is used as a part of hormone replacement therapy in women who have passed menopause (the change of life) and have not had a hysterectomy (surgery to remove the uterus). Hormone replacement therapy usually includes estrogen, which is used to treat symptoms of menopause and reduce the risk of developing certain diseases. However, estrogen can also cause abnormal thickening of the lining of the uterus and increase the risk of developing uterine cancer. Progesterone helps to prevent this thickening and decreases the risk of developing uterine cancer. Progesterone is also used to bring on menstruation (period) in women of childbearing age who have had normal periods and then stopped menstruating. Progesterone is in a class of medications called progestins (female hormones). It works as part of hormone replacement therapy by decreasing the amount of estrogen in the uterus. It works to bring on menstruation by replacing the natural progesterone that some women are missing.
How should this medicine be used?
Progesterone comes as a capsule to take by mouth. It is usually taken once a day in the evening or at bedtime. You will probably take progesterone on a rotating schedule that alternates 10 to 12 days when you take progesterone with 16 to 18 days when you do not take the medication. Your doctor will tell you exactly when to take progesterone. To help you remember to take progesterone, take it around the same time in the evening. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take progesterone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take progesterone as directed even if you feel well. Do not stop taking progesterone without talking to your doctor.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
