Does any one know is Singulair allergy medication cause headache?
I have had really bad headache for a while, and I was wondering if that medication could be the cause.
Thanks for the help!
Answers: The soft Singulair gave my daughter headaches and also caused her to stutter when she be 5. The docs said "no way".. but when she was off the side effects went away. When on they would return withink 4 days. The doctors still speak it wasn't the singulair. I think it was.
