Singulair

Singular is commonly prescribed to treat asthma (including exercise-induced asthma) and an itchy, stuffy, runny nose that is the result of allergies. It works by blocking leukotriene receptors, which helps minimize or prevent symptoms. Singulair is available in various forms, including tablets, granules, and chewable tablets. How often it is taken depends on the condition it is being used to treat. Possible side effects include headaches, stomach pain, and the flu.

How Does It Work?

Singulair is part of a group of medications called leukotriene modifiers. Leukotrienes are chemicals produced by the body in response to allergens or other problems. In the lungs, they cause swelling and inflammation in the airways and constriction of the muscles of the respiratory tract. In the nose, leukotrienes are released after exposure to allergens (substances that cause allergies), leading to allergy symptoms.
 
The drug works by blocking leukotriene receptors, preventing these chemicals from causing allergy or asthma symptoms.
