Abstract
Background
Montelukast’s new boxed warning for neuropsychiatric events questions its use in the setting of coronavirus disease 2019 (COVID-19) due to increased risk for new-onset psychiatric diagnoses.
Objective
We aim to evaluate the impact of using montelukast in patients hospitalized with COVID-19 on neuropsychiatry-related healthcare utilization and depression.
Methods
This retrospective nationwide observational cohort study using the Veterans Health Administration database included patients from January 1, 2020, through July 1, 2021. The treatment cohorts consisted of patients with and without montelukast use prior to COVID-19 hospitalization and matched using propensity score (PS) to two control cohorts: patients with COVID-19-related hospitalization without prior montelukast use and patients with prior montelukast use who were hospitalized for reasons other than COVID-19. The primary outcome of psychiatric hospitalizations at 90 days and 180 days and mental health visits at 180 days were compared using Poisson or negative binomial regression. Secondary outcomes of new-onset depression and new use of antidepressants were analyzed using multivariable logistic regression.
Results
After PS matching, a total of 415 patients were included in COVID-19 with and without montelukast matched cohort and 409 patients in montelukast with and without COVID-19-related hospitalization matched cohorts. For the primary outcomes, inpatient psychiatric hospitalization at 90 days [incidence rate ratio (IRR) 95% CI 1.79 (1.36–2.36)] and 180 days [IRR 95% CI 1.79 (1.32–2.25)] and mental health visits at 180 days [IRR 95% CI 1.72 (1.45–2.03)] were significantly higher in the montelukast with COVID-19 hospitalization group compared with those hospitalized without COVID-19. No difference in primary outcomes were noted in patients hospitalized with COVID-19 with and without use of montelukast. No significant difference was found in the secondary outcomes between either comparator group.
Conclusions
Patients with prior montelukast use who were hospitalized with COVID-19 appeared to have increased rate of neuropsychiatry-related healthcare utilization.
