Singulair Medicine Information

Singulair® (

Although most people respond well to Singulair, information about the medicine should still be discussed with your healthcare provider before treatment begins. It is also important to let your healthcare provider know beforehand if you are pregnant, have phenylketonuria, or liver disease.

When side effects do occur, they are often minor and either do not require medical attention or can be treated easily.
 
Singulair is typically taken by mouth once a day and is available in the form of tablets, chewable tablets, and oral granules (which can be dissolved in liquids or soft foods).
