Desloratadine 

(des lor at' a deen)

WHY is this medicine prescribed?

Desloratadine is used to relieve hay fever and allergy symptoms, including sneezing; runny nose; and red, itchy, tearing eyes. It is also used to treat hives. Desloratadine is in a class of medications called antihistamines. It works by blocking histamine, a substance in the body that causes allergic symptoms.

HOW should this medicine be used?

Desloratadine comes as a tablet, oral solution (liquid), and an orally disintegrating tablet to take by mouth. It is usually taken once a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take desloratadine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

To take the orally disintegrating tablet, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it on your tongue. The tablet will quickly dissolve and can be swallowed with saliva. Orally disintegrating tablets may be taken with or without water.
