This medicine is a leukotriene receptor antagonist used for the prevention and long-term treatment of asthma. It is used to prevent asthma attacks caused by exercise and to relieve allergy symptoms (eg, itchy, runny, or stuffy nose; sneezing) in certain patients. This medicine works by blocking substances in the body called leukotrienes. Blocking leukotrienes improves asthma and seasonal or perennial allergy symptoms. It may also be used to treat other conditions as determined by your doctor.
