How should Singulair be used to relieve my allergies?
Singulair comes as a tablet and as a chewable tablet to take by mouth. It is usually taken once a day in the evening. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Singulair exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Singulair controls asthma but does not cure it. Continue to take Singulair even if you feel well. Do not stop taking Singulair without talking to your doctor.
What special precautions should I follow if I start taking Singulair?
Before taking Singulair,
- tell your doctor and pharmacist if you are allergic to Singulair or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially phenobarbital (Solfoton), rifampin (Rifadin, Rimactane), and vitamins.
- tell your doctor if you have or have ever had phenylketonuria or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking Singulair, call your doctor.
What should I do if I forget a dose of Singulair?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What storage conditions are needed for Singulair?
Keep Singulair in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
