June 16,2004 I started taking Singulaire about 3 months ago , along with three blood pressure medications and a couple of other medications. I started having extreme weakness in my legs and couldn't trace it to anything I"d done or not done. This was the only new drug I was on. When i get off it, the weakness subsides but the allergy, coughing etc comes back. it's wonderful for my allergies, but I can't walk any distance without this weakness in my legs practically stopping me in my tracks. i"m off it again for awhile.
