How does claritin work?

Allergies are the body’s reaction to normally harmless substances that do not have unusual effects on other people. This is the result of the release of histamine from some cells in the human body. The Claritin drug is an antihistamine. It therefore blocks histamine from binding with histamine receptors that induce the allergic reaction in the body.

Normally people will experience nasal congestions because of their allergies. But antihistamines do not work on this particular symptom of an allergy. So to treat these congestions, nasal decongestants are added to the Claritin drug just for this purpose.

The Claritin drug is also able to block the same histamines that cause the formation of hives. These hives may be brought about but allergies or some other external factor.
