Desloratadine is prescribed to treat symptoms caused by an allergic reaction. Allergic reactions happen when your body thinks that harmless substances, like pet dander or peanuts, are actually pathogens that could make you sick. When this happens, your body prompts an immune response - which causes the symptoms like itchy eyes, itchy or runny nose, and scratchy throat that make allergic reactions troublesome.
Seasonal allergy symptoms can include allergic rhinitis (sneezing, runny nose, itchy nose, sinus pressure or pain, nasal congestion), and swollen or red itchy eyes. There is no cure for allergies, but a treatment plan can manage the symptoms listed above.
Desloratadine is also prescribed for the treatment of hives. Hives, also known as urticaria, are red, itchy bumps on the skin caused by exposure to an irritant or allergen. The size and severity of these welts will vary, but they often migrate to various areas of the body. All sorts of things can trigger hives. Exposure to an irritating substance (known as an allergen) will trigger your immune system’s allergic response, a release of chemicals called histamines. This reaction may result in hives and swelling. Pollen, pet dander, mold spores, and food allergies can all cause hives.
