Desloratadine — Uses, Dosage, Side Effects & Safety

Drug class: Second-generation antihistamine

Overview

Desloratadine is a non-drowsy antihistamine used to relieve allergy symptoms such as sneezing, runny or itchy nose, itchy or watery eyes, and itching of the throat or skin. It is commonly prescribed for allergic rhinitis (hay fever) and chronic idiopathic urticaria (hives). Desloratadine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Unlike some older antihistamines, it is less likely to cause drowsiness because it does not easily cross into the brain. Key points: Desloratadine is taken once daily, with or without food. It provides 24-hour relief from allergy symptoms and is suitable for adults and children over 6 months (oral solution). Always follow your healthcare provider’s instructions and do not exceed the recommended dose.
