Healthcare products regulatory agency symptoms and conditions

Has anyone experienced vision problems ? Seeing red and green dots ?

Does anyone know if Singulair can cause heart valve problems? I just found out that I have Mitral Valve Prolapse, and have never had any problems until after taking Singulair. Any info would be greatly appreciated...especially from Concerned Citizen if he's out there...

Thanks,

K.

May 16 y.o. daughter has chronic sinus infections and sever headaches. They said it was allergies and put her in Allegra D and Singulair. Headaches seemed better with slightly fewer sinus infections. Once I heard about the mood swings and Singulair I took her off. Then the Allegra did not seem to be able to keep up with keeping the sinus infections at bay. We finally figured out that she has a deviated septum and will need surgery. Anyway, we put her back on Singulair so we can get though the season with as few sinus infection until we can schedule surgery around high school and sports. Then we were noticing how her hair has become so thin. She used to have really thick hair and now her pony tail is to thin and small. After doing internet searching, we found out that other people are having this problem with Singulair. I took her off of it 4 days ago and already the shower has less hair in it. You can't tell a teenager that she needs to stay on a medication and lose a ton of hair. I am hoping that her hair will grow back quickly.
