I'd rather have allergies than take this medication again. Actually, I'm going to appeal for an Rx for Allegra, which gave me no problem.
The side eeks from Singulair I experienced were: clenched teeth, hard time falling asleep, racing thoughts, awful body aches, hard time waking up and a feeling of general malaise.
I'm sure this drug works miracles for some folks, but for me? I'd rather sneeze and drip.
