Almost every symptom you listed in your post is on Singulair's label as a side effect. Dyspepsia (indegestion) was reported in the clinical trials more commonly in Singulair than placebo.

In June 2009, the FDA recognized Singulair's neuropsychiatric side effects and recommended that: "Patients and healthcare professionals should be aware of the potential for neuropsychiatric events with these medications. Patients should talk with their healthcare providers if these events occur. Healthcare professionals should consider discontinuing these medications if patients develop neuropsychiatric symptoms."

Please visit www.parentsforsafety.org for comprehensive information about Singulair and help us raise awareness of Singulair's side effects by sharing the information on our site with your son's doctors. We have a printable "Singulair Side Effect Alert" you can mail along with a copy of the FDA's January 09 announcement.

The 10 mg dose is only approved for adults and adolescents 15 years and older.

Highly unlikely,well we must all be crazy,this drug is awful,10mg is an adult dosage,my 14 yr old was on 5mg,and what it did to him was devastating,your doctor needs an education in this drug,i think you should give it to him.Good luck

You're right, this dr. is an idiot. I have put way too much trust in the doctors. Time to follow my gut. Think this practice will be getting a letter letting them know what I think................

Just curious if you have found anything for your son's exercised induced asthma conditions? My son has been put on it and has been complaing as well with stomache pains and is pretty aggressive.
