Update: I have spent hours searching scientific data bases for articles on Singulair. So far this is the most direct reference to adverse drug reactions and Singular. For anyone who wanted to print the article from the Swedish researchers that stated that their study suggested that montelukast (singulair) should be investigated for adverse psychiatric drug reactions, I was able to find a link with open access to the public. So far, this is the only article that I have found. I am still searching through databases. This link should work if you cut and past. I am sure that all doctors would appreciate the opportunity to read it for themselves to see what they think. http://www.biomedcentral.com/1472-6904/8/1 Individual case safety reports in children in commonly used drug groups – signal detection Gertrud Brunlöf , Carina Tukukino and Susanna M Wallerstedt Department of Clinical Pharmacology and Regional Pharmacovigilance Centre, Sahlgrenska University Hospital, SE-413 45 Göteborg, Sweden author email corresponding author email BMC Clinical Pharmacology 2008, 8:1doi:10.1186/1472-6904-8-1 Conclusion In conclusion, the present study indicates that ADRs are reported for commonly used drugs in children. The number of ICSRs varies in different groups of drugs. A possible signal for montelukast and psychiatric adverse drug reactions was found, which should be further explored. Please don't forget to print the Tables which open on a separate page. Table 2 lists the specific side effects that they found which include anxiety, aggression, night mares, pain, and several others.
