Achieved symptoms and conditions

Has anyone ever had tons of weight gain while taking Singulair? I have been on this drug for about four years now and my weight has increased to more than 50 pounds of weight gain! I have a lot of aches and pains, leg cramps at night, insomnia, but the asthma has improved. I still get my once a year very bad attack with bronchitis, etc, but the improvement was great.

I have had everything else checked out for my weird continued weight gain and everything is normal. So I am checking out this drug and one other I am on for thyroid. (No, it's not my thyroid, my thyroid tests are normal now). It doesn't matter what I do I gain weight. Just wondering if this drug is causing it. My doc told me it was the cause of my insomnia and suggested moving it to the A.M..

I am tired of this weight gain, and it is starting more physical problems, like my bad knees. I ahve always been active and my eating habits haven't changed. Dieting is not working either. Any suggestions? Anyone else gaining unexplained weight?

Thanks!

Been on Singulair since 98. I am 53. I too get heart palpitations and difficulty breathing for a short period a few minutes after taking it but only once in a while. It helps my asthma but if I go off of it for a while my breathing is quite impaired for 4 or 5 days then improves but not to the level achieved with the Singulair. I dream more and have some nasty nightmares especially if I take ibuprofin at bed time. The reason I go off of the drug periodically and take Ibuprofin is that I am much more succeptible to muscle cramping, spasms, hip pain and tendonitis while on this drug. I used to be a runner/racer but had to quit race training because my back and neck would cramp up. I get tendonitis easily in my forarms from activities that never bothered me before. I have had back spasms for 2 months that did not improve with ice, heat, Ibuprofin, chiropractic or physical therapy until I remembered the Singulair connection two days ago and stopped taking it. Today I am noticing improvement for the first time. Once my back heals up I think I will try reducing the dosage to 5 mg and see if it is enough to help my breathing without the muscle problems.
