Singulair, also known by its generic name montelukast, is a medication commonly prescribed to treat asthma and allergic rhinitis. It belongs to a class of drugs called leukotriene receptor antagonists, which work by blocking the action of leukotrienes in the body. Leukotrienes are chemicals in the body that can cause inflammation, bronchoconstriction, and mucus production in the airways, leading to asthma symptoms.

Singulair is typically taken orally in the form of a tablet or chewable tablet, and is usually taken once daily in the evening. It is important to follow your healthcare provider’s instructions on how to take this medication, as well as any specific dosing recommendations.

This medication is often used as a maintenance treatment for asthma, helping to prevent asthma attacks and improve lung function. It can also be used to help manage symptoms of allergic rhinitis, such as sneezing, runny nose, and nasal congestion.

As with any medication, Singulair may cause side effects in some individuals. Common side effects may include headache, stomach pain, and fatigue. It is important to discuss any concerns or side effects with your healthcare provider.

It is important to note that Singulair is not a rescue medication and should not be used to treat acute asthma attacks. If you are experiencing sudden or severe asthma symptoms, you should seek immediate medical attention.

Overall, Singulair can be an effective and well-tolerated medication for many individuals with asthma or allergic rhinitis. If you have any questions or concerns about this medication, be sure to speak with your healthcare provider.
