Does Singulair Help with Allergies?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Yes, Singulair effectively treats allergic rhinitis and helps control seasonal and year-round allergy symptoms. This prescription medication belongs to a class called leukotriene receptor antagonists, which block inflammatory chemicals that cause nasal congestion, sneezing, and runny nose. Clinical studies show Singulair reduces allergy symptoms by approximately 15-20% compared to placebo. The medication is FDA-approved for treating both seasonal allergies (like pollen) and perennial allergic rhinitis (dust mites, pet dander). Unlike antihistamines that provide immediate relief, Singulair may take 2-4 weeks to reach full effectiveness. It's particularly beneficial for people with both asthma and allergies, as it addresses both conditions simultaneously.
