My M.D had prescribed Singulair approximately 3 months ago. I was extremely hesitant to take it and did research online before i made my final decision. I am/was fortunate not to have many of the side effects as stated in the other postings. Upon filing the second refill, I noticed I was putting on weight. My eating habits and daily routine has not changed prior to taking Singular or during taking the course of taking the pill. I started to become very concerned and I too found this site. I can tell you for a fact, that there is a very definite side effect of weight gain. I have gained weight all over my body, not only limited to the stomach area. As a result, I too, will NOT continue taking this pill, not only because of the weight gain, but in addition to the fact that my allergies are still bothering me. I am going to try Zyrtec, which is now an over- the -counter allergy pill. Zyrtec, until last year, was by prescription only. In final, to all those that are complaining of weight gain and various serious side effects, you are not crazy, The symptoms you are experiencing are real. Good luck to all of you.
