Montelukast (Montelukast sodium) — Uses, Dosage, Side Effects & Safety

Drug class: Leukotriene receptor antagonist (LTRA)

Overview

Montelukast is a prescription medication used to help prevent and manage symptoms of asthma and allergic rhinitis (hay fever) in adults and children. It is also sometimes prescribed to prevent exercise-induced bronchoconstriction (narrowing of the airways caused by exercise). Montelukast works by blocking leukotrienes, which are chemicals in the body that cause inflammation, swelling, and tightening of the airways. By reducing the effects of leukotrienes, montelukast helps to decrease asthma attacks, improve breathing, and relieve allergy symptoms such as sneezing, runny nose, and nasal congestion. It is not a rescue medication and should not be used to treat sudden asthma attacks. Key points: Take montelukast regularly as prescribed, even if you feel well. It is important to continue other asthma medications unless your doctor tells you to stop. Always carry your rescue inhaler for acute symptoms.
