Singulair Medication Information

Singulair® (
 montelukast sodium) is a drug often used for treating nasal allergy symptoms and asthma. It belongs to a class of medicines known as leukotriene modifiers and works by inhibiting the effects of a certain chemical in the body that causes allergy or asthma symptoms.
 
The medicine, which is typically taken once a day, is available by prescription only and comes in the form of tablets, chewable tablets, and oral granules (which can be dissolved and mixed with liquids or soft foods).
 
Before you begin treatment with Singulair, medication information should be reviewed with your healthcare provider to help minimize risks and to ensure a safe treatment process. Most people respond well to this drug, but you should let your healthcare provider know if you have any other existing medical conditions before taking it. Talk to your healthcare provider if you are pregnant, have liver disease, or have phenylketonuria.
