Singulair? Singular drug is a common misspelling of Singulair.
Singular® uses include the prevention of asthma (including exercise-induced attacks) and nasal allergies that cause an itchy, stuffy, or runny nose. It blocks leukotriene receptors, which prevents them from causing symptoms. How often it is taken depends on the condition it is being used to treat. The Singulair drug is available in various forms, including tablets, granules, and chewable tablets.
