How do leukotriene modifiers work to treat allergies?

ANSWER

Leukotriene modifiers are prescription drugs that treat asthma and nasal allergy symptoms. They block the effects from a chemical called leukotrienes, which your body releases in response to an allergic reaction. The chemicals cause inflammation, or swelling. This medication comes in pills, chewable tablets, and granules you take by mouth. They sometimes can cause side effects that include heartburn, upset stomach, stuffy nose, fever, cough, and rash.
