Interactions with Medications

Along with their needed effects, progestins used in high doses sometimes cause some unwanted effects such as blood clots, heart attacks, and strokes, or problems of the liver and eyes. Although these effects are rare, some of them can be very serious and cause death. It is not clear if these problems are due to the progestin. They may be caused by the disease or condition for which progestins are being used.

The following side effects may be caused by blood clots. Although not all of these side effects may occur, if they do occur they need immediate medical attention.

Get emergency help immediately if any of the following side effects occur:


Symptoms of blood clotting problems, usually severe or sudden, such as:
