Progesterone Micronized

This form:

Warning

Progesterone is sometimes used with another medication (a type of estrogen) as combination hormone replacement therapy (HRT) in women after menopause. Combination HRT can rarely cause very serious side effects such as heart disease (such as heart attacks), stroke, serious blood clots (such as in the lungs and legs), dementia, and breast cancer. Some of these risks appear to depend on the length of treatment and other factors. Combination HRT should be used for the shortest possible length of time at the lowest effective dose so you can obtain the benefits and minimize the chance of serious side effects from long-term treatment. Combination HRT should not be used to prevent heart disease or dementia. Discuss the risks and benefits of treatment and your personal health history with your doctor. If you take combination HRT, check with your doctor regularly (such as every 3-6 months) to see if you still need to take it.

If you use this medication for an extended period, you should have a complete physical exam at regular intervals (such as once a year) or as directed by your doctor. See also Notes section.
