singulair and menstrual

Hello! I started taking singulair like 4 months ago and I have noticed some change in my menstrual periods. They became heavier, like prolonged with severe abdominal pain. Is there anybody who has experienced similar effects with singulair?

Hello! It is a bit strange for singulair to influence periods. I have never heard of that but hey, one never knows how singulair can affect you. Similar to yours I have only had abdominal pain but it had nothing to do with periods. You never said how old you are, maybe you are experiencing some normal hormonal changes and singulair is just a coincidence.

I had bled for a few days, maybe 4 - heavy and ended up in the hospital for a D&C - - almost near death - thought it was from my IUD but it wasn't - then I read about the singulair and here I am doing research on the side effects of singulair.

I had the same problem with Singulair. I recommend having your doctor report this as an adverse event on Medwatch at http://www.fda.gov/medwatch. It is currently not listed as a side effect of the drug, but if enough people report this symptom, it will. Please consult your doctor before going off the drug as you might suffer from withdrawal symptoms such as severe coughing.
