There is no generic version of Singulair available in a 100mg strength. Singulair, with the active ingredient Montelukast, is commonly prescribed in 10mg tablets for asthma and allergic rhinitis. As a leukotriene receptor antagonist, Singulair works by blocking the action of leukotrienes, reducing inflammation in the airways. It is not a rescue medication but is used for long-term asthma control. Common side effects include headache and upper respiratory infections. It’s crucial to adhere to the prescribed dosage and consult a healthcare professional for guidance on usage and potential side effects.

This medication is much better than the other generic medication. Generic Singulair is really a wonderful and effective medication that definitely gave me relief from the complication.
