RCT 68 post-COVID-19 outpatients showing improvement in cough severity measures with montelukast treatment. The montelukast group had a greater reduction in number of cough paroxysms per day, cough severity visual analog scale, cough severity index, and improved cough quality of life scores compared to the control group. The montelukast group also had a shorter duration of cough.

Value of montelukast as a potential treatment of post-COVID-19 persistent cough: a non-randomized controlled pilot study

Background: This pilot study included 68 cases with post-COVID-19 persistent cough (> 8 weeks), randomly allocated into two groups; intervention group (32 patients) received standard cough therapy, and montelukast 10 mg/ day for 14 days and control group (36 patients) received only cough sedatives. Results: We found a significant improvement in the number of cough paroxysms/day, cough severity visual analog scale, cough severity index and cough quality of life, shorter duration improvement, and minimal side effects in the interventional group. Conclusions: We suggest that montelukast may be effective to reduce the duration and severity of the persistent post-COVID-19 cough and further improve quality of life.
