A little over 5 months ago I started taking Montelukast (Singulair). Shortly after my hair began falling out. I think I'm about 30-35% bald. Years ago I quit using singulair because I lost my insurance but it worked so well for me so I was happy to go back on it. I never had any side effects before and hair loss was not included on the list of possible side effects. About 2 weeks ago I quit taking it due to other side effects but have noticed my hair has started to come back a little in the bald areas. I googled Alopecia and Singulair and found some other people that seemed to have same issue. Anyone else??
