The inhibition of 5-HT by cyproheptadine improves cognitive function in schizophrenia disorder. Cyproheptadine is effective for treating functional gastrointestinal disorders (FGIDs). Food and Drug Administration (FDA) approved cyproheptadine, has antidepressant and antiplatelet functionality. It may be effective in treating thromboembolic disorders. Cyproheptadine inhibits lysine methyltransferase 7/9 (Set7/9) leading to a decrease in estrogen receptor (ERα) expression and growth arrest in breast cancer cells.

Veterinary Drugs and Treatments

Cyproheptadine may be useful in cats as an appetite stimulant. It potentially may be of benefit in the treatment of feline asthma or pruritus in cats, but clinical experience is marginal for this indication.
Cyproheptadine is an antihistamine but its efficacy is questionable for this indication in dogs. The drug may be useful as adjunctive therapy for Cushing’s syndrome probably as result of its antiserotonin activity, however one study demonstrated efficacy in less than 10% of dogs treated for pituitary dependent hyperadrenocorticism.
Cyproheptadine may be useful as adjunctive treatment in dogs or cats with serotonin syndrome.
In horses, cyproheptadine has been used for treating photic head shaking and pars intermedia dysfunction (Equine Cushing’s Disease).
