What is Clarinex-D 24 Hour?

Clarinex-D 24 Hour contains a combination of desloratadine and pseudoephedrine. Desloratadine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Clarinex-D 24 Hour is used to treat sneezing, runny or stuffy nose, itchy or watery eyes, hives, skin rash, itching, and other symptoms of allergies and the common cold.

Clarinex-D 24 Hour is for adults and children who are at least 12 years old.
