My son started taking singulair in 1999 when he was 12. He was also taking Flonase, Flovent, and Claritin. Currently he is taking Singulair and Clarinex only. He takes these medications year round for asthma and allergy problems. Over the past few years we have gone through an emotional hell that is difficult to describe. Let's just say he has been through counseling and is currently in anger management. I thought that these were life related things.... but he says it isn't and that life isn't bad. He can't name anything he is angry about. Basically, he's a kind, gentle and happy guy. Now he is experiencing blackouts when he is awake. Sounds strange doesn't it. He can't sleep during the night, hears people talking (not to him), sees things that aren't really there but only for a second, and has asked me to get him some help because he feels like he is going crazy. He scares himself. He is 19. I made an appt with a neurologist but the end of February is the soonest we can get in. I would tell him to stop taking it now but just missing one day produces major panic attacks... in a physical sense. I urge parents to try other avenues before singulair, then monitor it closely. It is a dopamine agonist and messing with the receptors or storage modes of dopamine does not appear to be a good idea.
