i have really been concerned about my hair loss for couple of months. to the point that am seeing thinning hair all over my body. i just read this forum online and started to realize that i have been on singulair for about 1 and 1/2 year. i have noticed excessive hiar loss since last year july. I first thought that i was just stressed out ut reading all you guys's comments on singulair i am starting to think that it could be the reason. i have noticed that i have to unclog drain a couple of times while taking a shower. I am horrified. My eyelashes have started thinning and it is noticeable. I am having mood swing and sudden outburst of uncontrollable anger. Is there any one else having similar hair loss problem. i am going to talk to my primary physician in july but i am not sure that i should quit taking it until then or go ahead and ask physician at my appointmemt. please somebody help me if you know any more information about singulair and hair loss?
