What is Cyproheptadine used for?
Cyproheptadine is an antihistamine and antiserotonergic medication. It is primarily used to treat allergic reactions such as hives and angioedema. It is also sometimes used to stimulate appetite in individuals experiencing weight loss or poor appetite [1][3].
How does Cyproheptadine work?
Cyproheptadine functions by blocking the action of histamine, a substance produced by the body during an allergic reaction. Histamine causes symptoms like itching, swelling, and hives. Cyproheptadine also has antiserotonergic properties, which may contribute to its appetite-stimulating effects. The exact mechanism for appetite stimulation is not fully understood but is thought to involve its effects on serotonin pathways [1][3].
