What is Cycrin?
Cycrin is a progestin (a form of progesterone), a female hormone that helps regulate ovulation (the release of an egg from an ovary) and menstrual periods.
Cycrin is used to treat conditions such as absent or irregular menstrual periods, or abnormal uterine bleeding. Medroxyprogesterone is also used to decrease the risk of endometrial hyperplasia (a condition that may lead to uterine cancer) while taking estrogens.
Cycrin is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.
Cycrin may also be used for other purposes not listed in this medication guide.
What is the most important information I should know about Cycrin?
You should not use this medication if you are pregnant, or if you have liver disease, a hormone-related cancer such as breast or uterine cancer, a history of stroke or blood clot, or abnormal vaginal bleeding that has not been checked by a doctor.
Cycrin will not prevent heart disease, breast cancer, or dementia, and may actually increase the risk of developing these conditions in post-menopausal women. Medroxyprogesterone may also increase the risk of uterine or ovarian cancer in some women. Long-term treatment with estrogens and progestins (such as medroxyprogesterone) may also increase your risk of heart attack, blood clot, or stroke.
Talk to your doctor about your specific risks and benefits of taking this medication, especially if you smoke or are overweight. Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.
