What is desloratadine and pseudoephedrine (Clarinex-D 12 Hour, Clarinex-D 24 Hour)?
Desloratadine is an antihistamine that reduces the 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).
The combination of desloratadine and pseudoephedrine is used to treat sneezing, cough, runny or stuffy nose, itchy or watery eyes, hives, skin rash, itching, and other symptoms of allergies and the common cold.
Desloratadine and pseudoephedrine is for use in adults and children who are at least 12 years old.
