Background

Cyproheptadine is a potent competitive antagonist of both serotonin and histamine receptors. It is used primarily to treat allergic symptoms, though it is perhaps more notable for its use in appetite stimulation and its off-label use in the treatment of serotonin syndrome.

Indication

In the US, prescription cyproheptadine is indicated for the treatment of various allergic symptomatologies - including dermatographia, rhinitis, conjunctivitis, and urticaria - as well as adjunctive therapy in the management of anaphylaxis following treatment with epinephrine. In Canada, cyproheptadine is available over-the-counter and is indicated for the treatment of pruritus and for appetite stimulation. In Australia, cyproheptadine is additionally indicated for the treatment vascular headaches.

Cyproheptadine is also used off-label for the treatment of serotonin syndrome.
