How Does This Medication Work?
Montelukast belongs to a group of medications known as leukotriene receptor antagonists. It is used to prevent and manage asthma symptoms and to relieve the symptoms of seasonal allergies, also known as seasonal allergic rhinitis or hay fever. It may also be used to treat asthma symptoms caused by exercise (exercise-induced bronchoconstriction). It works by blocking the effects of leukotrienes, a substance produced by the body in response to certain "triggers" that cause narrowing and swelling of airways in the lungs. It may be taken alone or in addition to other asthma medications. Montelukast usually starts to work within one day.
When used to prevent and manage asthma, it is important to understand that montelukast should not be used to relieve an asthma attack once it has started. People with asthma should always have their fast-acting asthma relief medication on hand to treat an asthma attack.
Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
