Tell your doctor right away if you have signs of blood vessel inflammation: flu-like symptoms, severe sinus pain, a skin rash, numbness or a "pins and needles" feeling in your arms or legs.
Stop taking this medicine and call your doctor right away if you have any unusual changes in mood or behavior (such as agitation, confusion, depression, sleep problems, compulsive behaviors, hallucinations, or suicidal thoughts or actions).
Montelukast is a leukotriene (loo-koe-TRY-een) inhibitor that is used to prevent asthma attacks in adults and children at least 2 years old. Montelukast is also used to prevent exercise-induced bronchoconstriction (narrowing of the air passages in the lungs) in adults and children who are at least 6 years old.
Montelukast is also used to treat symptoms of seasonal or year-round (perennial) allergies in adults and children at least 2 years old, after other treatments did not work.
If you already take montelukast to prevent asthma or allergy symptoms, do not use an extra dose to treat exercise-induced bronchoconstriction.
Montelukast may also be used for purposes not listed in this medication guide.
You should not use montelukast if you are allergic to it.
Tell your doctor if you have ever had:
The chewable tablet may contain phenylalanine and could be harmful if you have phenylketonuria (PKU).
Tell your doctor if you are pregnant or breastfeeding.
Do not give this medicine to a child without a doctor's advice.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Montelukast is not a fast-acting rescue medicine for asthma attacks. Seek medical attention if your breathing problems get worse quickly, or if you think your medications are not working.
Montelukast is usually taken once every evening, with or without food.
For exercise-induced bronchoconstriction, take a single dose at least 2 hours before exercise, and do not take another dose for at least 24 hours.
Swallow the regular tablet whole, with a glass of water.
You must chew the chewable tablet before you swallow it.
Place the oral granules directly in your mouth and swallow, or mix them with applesauce, mashed carrots, rice, or ice cream. The granules may also be mixed with baby formula or breast milk. Do not use any other type of liquid. Use the mixture within 15 minutes. Do not save for later use.
If you also use an oral steroid medication, you should not stop using it suddenly. Follow your doctor's instructions about tapering your dose.
Do not change your dose or stop using asthma medication without your doctor's advice.
Store at room temperature away from moisture and heat. Do not open a packet of oral granules until you are ready to use the medicine.
Avoid situations or activities that may trigger an asthma attack.
If your asthma symptoms get worse when you take aspirin, avoid taking aspirin or other NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
Get emergency medical help if you have signs of an allergic reaction: hives, blisters, severe itching; difficult breathing; swelling of your face, lips, tongue, or throat.
Tell your doctor right away if you have signs of blood vessel inflammation: flu-like symptoms, severe sinus pain, a skin rash, numbness or a "pins and needles" feeling in your arms or legs.
