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 expats and travellers distant from a well stocked pharmacy.

No. Periactin is the originator brand name, made by MSD, and Yasabai uses it to identify the medicine: you receive a generic with the same active ingredient (cyproheptadine) at the same dose, mostly a recognised Indian branded generic. The exact brand depends on stock.

Periactin comes in a 4mg strength, in packs of 30 to 360 tablets, and the price per tablet for every option is shown above, in US dollars or the currency you choose. Larger packs cost less per tablet. Paying with Bitcoin or Ethereum gives you an extra 10% off.
