How does this medication work? What will it do for me?
Rupatadine belongs to the class of medications called second-generation antihistamines, specifically the class known as histamine receptor antagonists. It works by blocking the action of one of the body’s natural chemicals known as histamine. Histamine is responsible for many of the symptoms caused by allergies.
Rupatadine is used for the relief of symptoms associated with seasonal and year-round allergies, including sneezing, itchy and runny nose, and tearing and redness of the eyes. It is also used for the relief of symptoms associated with allergic skin conditions, including chronic hives, itching, and other skin disorders
Rupatadine usually starts working within 2 hours and lasts for 24 hours.
