How Does It Work?

Claritin-D contains two different medications: loratadine and pseudoephedrine. Allergies occur when the body's immune system reacts to normally harmless substances that do not bother most people. This reaction is partly caused by the release of histamine from certain cells in the body. Loratadine is an antihistamine, which means it blocks histamine from binding to histamine receptors and causing allergy symptoms. Since histamine is responsible for many of the symptoms of allergies, blocking it can be helpful. However, antihistamines are not helpful for nasal congestion, which is why loratadine is combined with pseudoephedrine.
 
Pseudoephedrine is a nasal decongestant that works by constricting the blood vessels in the nose, helping to relieve nasal congestion. It is useful for relieving nasal congestion due to many causes, including allergies and the common cold.
