What is Desloratadine?

Desloratadine belongs to a class of drugs called antihistamines. These drugs inhibit the histamine, one of the mediators of allergic reactions and reduce the associated symptoms, e.g., hives, running nose, itchy eyes, sneezing etc. These 5mg tablets also work well for chronic allergies. 

How does it work?

The body releases a chemical called histamine in response to allergic reactions. Desloratadine inhibits this chemical and reduces the symptoms associated with allergic reactions. 

Is Disloratadine suitable for me?

It is suitable for men and women who show acute or chronic allergy symptoms. It is, however, not to be used if you are allergic to the drug or the excipients used in the tablets.

Desloratadine is the biologically active metabolite of loratadine and is significantly more potent than it.
