Patient summary
Cyproheptadine 4mg tablets, used for allergic rhinitis and urticaria. A first-generation antihistamine that also blocks serotonin at its receptors.
Mechanism of action
Cyproheptadine is an antihistamine and antiserotonergic agent. It competes with histamine and serotonin at receptor sites, thereby reducing inflammation and allergic symptoms, while also possessing significant anticholinergic effects.
Periactin is the established brand name for cyproheptadine, a histamine antagonist used to treat symptoms of allergic rhinitis and urticaria. The medication serves as a reliable option for managing allergic responses. It is supplied as a 4mg tablet, offering a straightforward way to address symptoms throughout the day.
Buying Periactin online
Generic cyproheptadine, largely produced in India, offers a far more affordable option than the original brand for people in Australia who are distant from a well-stocked pharmacy.
