Science has NOT conclusively ruled out a link between Singulair and suicide. In fact, science DID reveal a link between Singulair and depression (a risk factor for suicide). In the clinical trials one montelukast participant dropped out and the investigator cited the reason as depression that was "drug related". Additionally, in the primary and Phase II/BIII Studies, 12 out of 1955 participants taking montelukast reported depression, vs. 5 out of 1108 on placebo, and 1 out of 251 on beclomethasone. This information is presented in the FDA's medical review for Singulair and is available on the FDA website. Depression was not only reported post-marketing as some would like us to believe. As the FDA explained in their update to the investigation, Singulair's clinical trials were not designed to measure neuropsychiatric events so some may not have been reported. Using clinical trial data to prove that Singulair cannot cause a particular symptom or outcome is as foolish as discounting post-marketing reports that show that some neuropsychiatric events associated with Singulair are consistent with a drug-induced effect.
