Zavert is a medication primarily used to treat symptoms of allergies, such as hay fever and other allergic reactions. It contains the active ingredient desloratadine, which is an antihistamine that helps reduce sneezing, runny nose, and itchy eyes. Zavert is available in various forms, including tablets and syrup, making it easy to administer for both adults and children. This medication works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Zavert is generally well-tolerated, with few side effects, and is often preferred for its non-drowsy formulation, allowing individuals to carry on with their daily activities without sedation.
