Sipriva is a medication that contains the active ingredient desloratadine, which is an antihistamine used to relieve allergy symptoms such as sneezing, runny nose, and itchy eyes. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Sipriva is often used in the treatment of allergic rhinitis and chronic urticaria (hives). As with any medication, it’s essential to follow a healthcare provider’s guidance on its use.
