Cyproheptadine, sold under the brand name Periactin among others, is a first-generation antihistamine primarily used to treat allergies. This may include itchiness, hay fever, and hives. It may also be used for serotonin syndrome. It is taken by mouth.

Common side effects include sleepiness, dizziness, agitation, and poor coordination. Other side effects may include swelling, problems urinating, and increased weight. There is no evidence of harm with use during pregnancy, however such use has not been well studied. Care should be taken in those at risk of glaucoma.

Cyproheptadine was patented in 1959 and came into medical use in 1961. It is available as a generic medication. In the United Kingdom 30 tablets of 4 mg costs the NHS about 6 pounds in 2020. This amount in the United States costs about 10 USD.
