I have an 8 yr old son that has allergies and asthma. The allergist recently prescribed Singulair which my son had taken when he was 5. We took him off of it back then due to anger outbursts. By the way, the Dr. said that was not a side effect, but nonetheless the issues subsided. When it was recently added back to his medication list, within 3 days he had anaphylactic type episodes 2 days in a row. The attack started with stomach pains, chest pains and then he couldn't breath AT ALL and turned blue! There was no time to call 911 so I gave him an Epi Pen. The attacks are still occurring yet milder and all his Dr.'s swear by Singulair and think I am crazy. I took him off Singulair immediately and we are still waiting for it to leave his system. I think that is why the recent episodes have been milder. He has been tested for all sorts of allergens which he did not come in to contact with prior to the anaphylactic events. We still have no answers and if I hear one more Dr. talk about how great Singulair is, I am going to freak out!! To heck with these drug companies and doctor's who get perks for prescribing medications without informing us of side effects.
