Looking for a montelukast sodium coupon? Montelukast sodium is the low-cost generic version of Singulair, a once-daily tablet used to help control asthma and ease allergy symptoms. Because it is a well-established generic, the cash price is usually modest, but what you pay can vary a lot from one pharmacy to the next, so comparing matters. Rx.com checks prices at more than 60,000 pharmacies, and our free discount card works whether or not you have insurance. Enter your ZIP above to see today's price near you.
What is montelukast sodium and how does it work?
Montelukast sodium is a leukotriene receptor antagonist (LTRA). Leukotrienes are natural substances the body releases that can cause airway tightening, swelling, and mucus in the lungs, along with allergy symptoms. Montelukast blocks these leukotrienes, which helps keep airways open and calms allergic inflammation. It is taken by mouth once a day and is used for long-term, ongoing control, not for stopping an attack that is already happening.
The FDA has approved montelukast for the prevention and long-term maintenance treatment of asthma in adults and children 12 months and older, for preventing exercise-induced breathing problems (exercise-induced bronchoconstriction) in people 6 years and older, and for relieving symptoms of seasonal allergic rhinitis (age 2 and older) and perennial (year-round) allergic rhinitis (age 6 months and older).
How much does montelukast sodium cost without insurance?
As a widely available generic, montelukast sodium is one of the more affordable long-term asthma and allergy medicines, but the cash price still swings widely between pharmacies in the same town. That is exactly why comparing prices pays off. With the free Rx.com discount card, you may pay less than a typical insurance copay, and the card can be used with or without coverage.

Montelukast vs. Singulair and other allergy options
Montelukast sodium is the same active ingredient as the brand-name product Singulair. The FDA-approved generic is substitutable and typically costs far less, so most people do well on the generic. Because it treats allergic rhinitis as well as asthma, some people compare it with common antihistamines and nasal sprays.
- Cetirizine, loratadine, and fexofenadine are once-daily antihistamine tablets for allergy symptoms.
- Fluticasone is a steroid nasal spray for nasal allergy symptoms.
These medicines work differently, and the right choice depends on your symptoms and health history. Because of montelukast's boxed warning (see below), the FDA advises reserving it for allergic rhinitis only in people who do not respond to or cannot tolerate other allergy therapies. Ask your provider or pharmacist which option fits you.
Safety and the boxed warning
Montelukast carries an FDA boxed warning for serious mental health (neuropsychiatric) side effects. These can include agitation, aggression, depression, sleep problems, and suicidal thoughts or actions. Patients and caregivers should watch for any new or changing mood or behavior and report it to a healthcare provider right away. Because of this warning, the benefits and risks should be weighed carefully, especially when it is being considered for mild allergy symptoms.
A few other points to know: montelukast is not for treating a sudden asthma attack, since it does not relieve acute bronchospasm, so keep your rescue inhaler on hand. The chewable tablets contain phenylalanine (from aspartame), which matters for people with phenylketonuria. Rare eosinophilic conditions (such as Churg-Strauss/eosinophilic granulomatosis) have been reported, often as a steroid dose is lowered, and you should not abruptly replace an inhaled or oral corticosteroid with montelukast. This is general information, not medical advice; talk with your provider about your situation.
