Singulair is a prescription medicine used in treatment and prevention of asthma. Doctors prescribe Singulair to decrease the number of asthma attacks and minimize the symptoms.
Singulair, however, is not intended to relieve an attack that already started.
Apart from asthma, Singulair is also used in prevention of exercise-induced bronchoconstriction (EIB). Singulair is also used to treat symptoms of allergic rhinitis such as runny nose, sneezing, wheezing, and itching.
Singulair can only be purchased with doctor's prescription.

In order for Singulair to work properly, it has to be taken at the same time each day, regardless if the condition gets better. Singulair may be taken with or without food. If you are using Singulair oral granules, do not open the packet unless you are ready to use it.
For children, Singulair granules may be dissolved in 5 ml of breast milk or baby formula; or mixed with a tablespoon of soft food like rice, ice cream, applesauce, or mashed carrots. Do not mix Singulair granules with any other liquid; only use breast milk or formula in dissolving the granules. Once the medicine is mixed, it should be taken within 15 minutes.
