Bronsky EA, Kemp JP, Zhang J, Guerreiro D, Reiss TF "Dose-related protection of exercise bronchoconstriction by montelukast, a cysteinyl leukotriene-receptor antagonist, at the en of a once-daily dosing interval. Singulair is indicated for prevention of exercise-induced bronchoconstriction EIB in patients 6 years of age and older. The effect of Singulair on eosinophils in the peripheral blood was examined in clinical trials. In patients with asthma aged 2 years and older who received Singulair, a decrease in mean peripheral blood eosinophil counts ranging from 9% to 15% was noted, compared with placebo, over the double-blind treatment periods.
Importance of contacting clinician promptly if asthma is not well controlled; seek medical attention if short-acting, inhaled β 2-adrenergic bronchodilators are needed more often than usual or if the maximum number of inhalations for a 24-hour period are exceeded.

This sometimes happens in people who also take a steroid medicine by mouth that is being stopped or the dose is being lowered.
Patients should be advised that, while using Singulair, medical attention should be sought if short-acting inhaled bronchodilators are needed more often than usual, or if more than the maximum number of inhalations of short-acting bronchodilator treatment prescribed for a 24-hour period are needed. If you have any questions about Singulair chewable tablets, please talk with your doctor, pharmacist, or other health care provider. Am J Respir Crit Care Med.
