Important Information

SINGULAIR is indicated for prophylaxis and chronic treatment of asthma in patients aged 12 months and older.

SINGULAIR should not be used as rescue medication to treat acute asthma episodes. Patients should be advised to have appropriate rescue medication available.

Use of SINGULAIR may not eliminate the need for inhaled or systemic corticosteroids. Patients should not decrease the dose or stop taking any other anti-asthma medications unless instructed by a physician.

Safety and effectiveness of SINGULAIR in patients younger than 12 months with asthma have not been established.

Patients should be advised to take SINGULAIR daily as prescribed, even when they are asymptomatic, as well as during periods of worsening asthma, and to contact their physician if their asthma is not well controlled.
