IMPORTANT SAFETY INFORMATION

SINGULAIR will NOT replace fast-acting inhalers for sudden symptoms. You should still have rescue medication available and continue to take your other asthma medications unless your doctor tells you to stop. For asthma, SINGULAIR should be taken once a day, in the evening as prescribed, whether or not you have asthma symptoms. If your symptoms get worse or you need to increase the use of your rescue inhaler, call your doctor at once.

Side effects are generally mild and vary by age, and may include headache, ear infection, sore throat, and upper respiratory infection. Side effects generally did not stop patients from taking SINGULAIR. Check with your doctor if you're pregnant or nursing. SINGULAIR should be taken once a day, as prescribed. SINGULAIR is available by prescription only.
