Why is Singulair prescribed?

Singulair relieves itchy, red, irritated, watery eyes; runny nose; sneezing; and itchy skin caused by hay fever and allergies. It also is used for motion sickness, before and after surgery as a sedative to relieve apprehension, and to prevent and treat nausea and vomiting.

Promethazine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should Singulair be used?

Singulair comes as a tablet, oral liquid, and rectal suppository. For allergies, Singulair usually is taken at bedtime or before meals and at bedtime. For motion sickness, it is taken 30-60 minutes before departure and again if needed in 8-12 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Promethazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. To insert a suppository, follow these steps:

• If the suppository feels soft, hold it under cold, running water for 1 minute. Remove the wrapper.
• Dip the tip of the suppository in water.
• Lie down on your left side and raise your right knee to your chest. (A left-handed person should lie on the right side and raise the left knee.)
• Using your finger, insert the suppository into the rectum, about 1/2 to 1 inch in infants and children and 1 inch in adults. Hold it in place for a few moments.
• Stand up after about 15 minutes. Wash your hands thoroughly and re sume your normalactivities
