Allergies Home > Singulair for Allergies

Singulair® (montelukast sodium) is a prescription medicine commonly used for treating asthma. Healthcare providers may prescribe Singulair for allergies as well (to treat nasal allergy symptoms such as irritated, itchy, stuffy, or runny nose).
By blocking leukotriene receptors, the drug can prevent leukotrienes (chemicals produced by the body in response to allergens or other problems) from causing allergy or asthma symptoms. Singulair has been shown to be safe and effective for adults and children as young as two years old (for seasonal allergies) or as young as six months old (for year-round allergies).
Although using Singulair for allergies is very common and considered relatively safe, you should tell your healthcare provider about any existing medical conditions you have before starting treatment. It is important to talk to your healthcare provider prior to using Singulair if you have phenylketonuria, liver disease, or any allergies (including allergies to food, dyes, or preservatives).
