What should I discuss with my healthcare provider before taking montelukast (Singulair)?
Do not use this medication if you are allergic to montelukast.
The chewable tablet form of this medication may contain phenylalanine. Talk to your doctor before using this form of montelukast if you have phenylketonuria (PKU).
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether montelukast passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take montelukast (Singulair)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Montelukast is usually taken once daily in the evening for prevention of asthma or allergy symptoms. For exercise-induced bronchoconstriction, take a single dose at least 2 hours before you exercise, and do not take another dose for at least 24 hours. Follow your doctor's instructions.
If you already take this medication to prevent asthma or allergy symptoms, do not use it for exercise-induced bronchoconstriction.
Swallow the regular tablet whole, with a glass of water.
The chewable tablet must be chewed completely before you swallow it.
The oral granules can be placed directly into the mouth and swallowed, or mixed with a spoonful of applesauce, mashed carrots, rice, or ice cream. Oral granules can also be mixed with 1 teaspoon of baby formula or breast milk. Do not use any other type of liquid for mixing the granules. Other liquids can be taken before or after taking the medicine.
After opening or mixing the oral granules, you must use them within 15 minutes. Do not save an open packet or mixed medicine for later use.
Montelukast will not work fast enough to treat an asthma attack that has already begun. Use only a fast-acting inhalation medicine to treat an asthma attack. Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing attacks.
It may take up to several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after several weeks of treatment.
Asthma is usually treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice, even if you have no asthma symptoms.
If you also take a steroid asthma medicine, do not stop using it suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.
Call your doctor right away if you feel that this medicine is not working as well as usual, or if it makes your condition worse. If it seems like you need to use more of any of your medications in a 24-hour period, talk with your doctor.
Store montelukast at room temperature away from moisture and heat. Do not open a packet of oral granules until you are ready to use the medicine.
