Does Singulair Cause Leg Cramps?

Singulair seems to help the lungs and coughing, but the muscle cramps are horrible. Keeps me up all night.

Answer

Muscle cramps are not a common side effect but a post approval study suggested that Singulair might be able to cause muscle cramps in some people. If they are bad enough to prevent you from sleeping you should definitely call your physician to see if there's another substitute or something that can help with them. You might try drinking a good amount of water/fluids before sleeping to ensure that you are well hydrated. Massage/heat before bed to relax the muscles can sometimes help as well. Good luck!
