Montelukast sodium is a medication that belongs to a class of drugs known as leukotriene receptor antagonists. It is used to treat asthma and seasonal allergies, including hay fever (allergic rhinitis).
Montelukast sodium works by blocking the action of leukotrienes, which are chemicals that contribute to inflammation and constriction of the airways in the lungs. By blocking the action of leukotrienes, montelukast sodium helps to reduce inflammation and open up the airways, making it easier to breathe.
Montelukast sodium is usually taken orally, once a day, with or without food. The dosage and duration of treatment will depend on the individual's condition and response to treatment. It may take several days or weeks for the full effects of montelukast sodium to be felt.
Common side effects of montelukast sodium include headache, upset stomach, and fatigue. More serious side effects are rare but can include allergic reactions, mood changes, and suicidal thoughts.
Montelukast sodium may interact with other medications, so it is important to inform your healthcare provider of all medications you are taking before starting treatment. It is also important to continue using any other asthma or allergy medications as prescribed by your healthcare provider, unless instructed otherwise.
Montelukast sodium is a prescription medication and should only be used under the guidance of a healthcare provider. It is important to follow the instructions provided by your healthcare provider for using this medication, including the proper dosage and frequency of use.
