The primary use of Desloratadine is for managing allergic conditions such as allergic rhinitis (also known as hay fever) and urticaria (hives). It belongs to the class of second-generation non-sedating antihistamines.
This medication is also used for perennial allergic rhinitis, which is a year-round allergy caused by indoor allergens like dust mites, mould, and pet dander. It is also indicated for chronic idiopathic urticaria, which refers to itching and hives with an unknown cause that lasts over six weeks.

Desloratadine is a second-generation, non-sedating antihistamine.
It works by selectively binding to histamine H1 receptors, which are proteins on the surface of cells. This blocks histamine, a chemical produced by the body during an allergic reaction, from attaching to these receptors and causing allergy symptoms.
Additionally, this medicine inhibits the release of pro-inflammatory cytokines like interleukins and tumour necrosis factor. These substances are produced by the immune system, causing inflammation and worsening allergy symptoms. By inhibiting these substances, Desloratadine reduces inflammation, and thus, the symptoms of allergy.
