Buy Periactin online


Periactin belongs to a group of drugs known as antihistamines and is used to lower the effects of histamine which is a natural chemical in the body. Periactin primarily relieves allergy symptoms such as runny the nose, itchy and watery eyes, hayfever and sneezing.


The active ingredient in Periactin is cyproheptadine hydrochloride. Inactive ingredients include sodium starch glycolate, magnesium stearate, microcrystalline cellulose, and lactose monohydrate.

Pharmacological Action

Periactin categorized as a first generation antihistamine works by inhibiting the effects of histamine. When allergic reactions happen in the body, histamine is released by body cells and in some cases, during viral infections such as common colds. When histamine binds receptors to other cells, it promotes changes within the cells that trigger a release of chemicals that cause itching, sneezing and an increase in mucus.


Periactin is used to relieve allergy symptoms such as runny the nose, hayfever, sneezing, itchy and watery eyes. This drug also helps to relieve itching common with skin conditions such as eczema, rash, hives, dermatitis, chickenpox and mild reactions as a result of insect bites. Periactin can also be used to treat migraines and other kinds of headaches that haven’t been cured by previous medications.
