Singulair: Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options Introduction: Singulair, also known as Montelukast, is a medication used for various respiratory conditions such as asthma, allergic rhinitis, and exercise-induced bronchoconstriction. This medication belongs to a group of drugs called leukotriene modifiers. It works by blocking certain substances called leukotrienes that cause inflammation, swelling, and narrowing of airways in the lungs. Uses: Singulair is primarily used for asthma in patients who are not well controlled by their current medication. It can also be used for allergic rhinitis to prevent symptoms such as runny nose, sneezing, and nasal congestion. This medication can also be used to prevent exercise-induced bronchoconstriction. Dosage: The recommended dosage for Singulair varies depending on the age of the patient and the condition being treated. For asthma in adults and children over the age of 15, the recommended dosage is 10 mg once daily. For children aged 6 to 14 years old, the recommended dosage is 5 mg once daily. For children aged 2 to 5 years old, the recommended dosage is 4 mg once daily. The dosage for allergic rhinitis and exercise-induced bronchoconstriction may vary, so it is important to consult with your doctor. Demographic: Singulair is approved for use in adults and children aged 2 years and older. It is typically prescribed for patients who have not responded well to other asthma medications or who have allergic rhinitis. Side Effects: Like any medication, Singulair may cause side effects.

It is important to tell your doctor about all the medications you are taking before starting Singulair. Some medications that may interact with Singulair include phenobarbital, rifampin, and some anti-seizure medications. Generic Options: The generic name for Singulair is Montelukast. This medication is available in a generic form, which is typically less expensive than the brand-name version. However, it is important to talk to your doctor before switching to a generic version of Singulair.
