Singulair Drug Information

Singulair® (montelukast sodium) is a prescription medicine often used for the treatment of asthma and allergic rhinitis.
 
By blocking leukotrienes (chemicals produced by the body in response to allergens or other problems), the drug can help reduce asthma symptoms and stuffy, itchy, or runny nose due to allergies.
 
Before you start taking Singulair, drug information should be discussed with your healthcare provider to help minimize risks. If you have phenylketonuria, liver disease, or any allergies, make sure to let your healthcare provider know before you begin treatment. It is also important to know that side effects are possible with this medication, including abdominal pain, headaches, and the flu.
 
Singulair comes in tablet form and is taken by mouth once a day (in the evening, if used for asthma), although some people take it only before exercising (for treating exercise-induced asthma). For younger children, it is also available in the form of chewable tablets and oral granules.
