How Loratadine Affects Patients
Desloratadine is a type of medicine that helps reduce allergy symptoms. It works by blocking one type of receptor (the H1 receptor) that histamine, a chemical released during an allergic reaction, attaches to. This prevents histamine from activating cells and producing the symptoms associated with allergies. Unlike other antihistamines, desloratadine does not enter the brain and does not cause drowsiness.
How Loratadine works in the body
Desloratadine helps to reduce allergy symptoms by blocking the effects of histamine. It does this by competing with histamine for binding to receptors in the body, keeping histamine from activating these receptors and causing symptoms. This provides temporary relief from symptoms like nasal congestion and watery eyes.

The advised dose of Loratadine is contingent upon the diagnosed condition, including Hay Fever, Nasal Congestion and non-nasal manifestations. The amount of dosage alters according to the technique of conveyance (e.g. Oral or Tablet, orally disintegrating - Oral) specified in the table below.
