Although you did not indicate which medication you are on, a number of medications (including psychiatric medications) can disrupt the menstrual cycle. Of course, a number of other factors can also influence the menstrual cycle, including significant weight loss, high levels of physical activity/exercise, chronic illnesses, medications, and abnormal functioning of the ovaries and the areas in the brain that control ovarian function (among other potential causes).

I would recommend that you discuss these concerns with both your psychiatrist and your primary physician, so that they can evaluate you further and advise you.

Sincerely/ Robert A. Wascher, MD, FACS
