Do you need a prescription for Singulair?
Yes. In the US, Singulair (montelukast) is prescription-only, and there’s no over-the-counter version. Before prescribing it, a doctor checks:
- Whether you have asthma, allergies, or both, and how well they’re controlled
- Any history of depression, anxiety, sleep problems, or other mood or behavior changes
- Whether other allergy treatments, such as nasal sprays or antihistamines, have worked for you
- Other medicines you take
With Your Doctors Online, a doctor can review this by chat and send your Singulair prescription to your local pharmacy if it’s right for you.

What is Singulair (montelukast) and what does it treat?
Montelukast belongs to the leukotriene modifier class of drugs. It reduces airway inflammation and hence helps treat asthma and allergies. In the US, it’s available as brand-name Singulair and as generic montelukast. It’s taken by mouth as a regular tablet, a chewable tablet, or oral granules. Zafirlukast and Zileuton are two other examples of drugs in this category. Montelukast should not be used as a first line of treatment for allergic rhinitis.
Available forms and strengths:
FDA boxed warning: Montelukast can cause serious mental health and behavior changes, including agitation, aggression, depression, nightmares, sleepwalking, hallucinations, and suicidal thoughts or actions. These can happen while taking it or after stopping it. Because of this risk, the FDA advises using montelukast for allergies only when other treatments don’t work well or can’t be used. Stop taking it and contact your doctor right away if you or your child notice any of these changes.

Contraindications and precautions
- Do not take Singulair if you are allergic to Montelukast or its ingredients.
- Closely monitor any serious mood changes or behavior while taking Montelukast, and tell your doctor about any history of depression or other mental health conditions before starting it.
- Some medicines, such as phenobarbital and rifampin, can lower montelukast levels and make it less effective. Tell your doctor about all the medicines you take.
- If your asthma is triggered by aspirin or NSAIDs (such as ibuprofen), keep avoiding them. Singulair doesn’t prevent this type of reaction.
- Chewable tablets contain phenylalanine, which matters for people with phenylketonuria (PKU).
- If you’re pregnant, planning a pregnancy, or breastfeeding, talk to your doctor. Montelukast is generally considered an option when it’s needed, but your doctor will weigh the benefits and risks.
- Don’t stop or reduce your other asthma medicines, such as inhaled steroids, unless your doctor tells you to.
