Abstract

Study objective: To estimate the rate of suicide in patients taking montelukast.

Design: Population-based cohort study.

Data source: United Kingdom General Practice Research Database.

Patients: A total of 23,500 patients who had received at least one prescription for montelukast in the cumulative data from February 1998-March 2007.

Measurements and main results: Rate of suicide was to be calculated as number of suicides divided by person-time at risk. Person-time of montelukast exposure was accrued for each patient as a cumulative duration of all prescriptions. The 23,500 patients had received 252,593 prescriptions for montelukast, representing 21,050 person-years at risk for suicide. We then sought to identify all cases that had a computer-recorded diagnosis of suicide; however, no cases of suicide were found in patients exposed to montelukast during our time frame.

Conclusion: The risk of suicide attributable to montelukast, if present at all, is extremely low in users.
