Cyproheptadine for dogs is an antihistamine used to control allergy symptoms. Veterinarians more commonly prescribe it for cats, though they may use it to treat dogs, as well. In cats, the drug helps stimulate the appetite, but this does not happen in dogs.
Cyproheptadine is sometimes known by the brand name Periactin, and you can only get it with a prescription from a vet, though the FDA has not approved it for veterinary use. Side effects of the drug are typically minimal, which can make it useful for dogs who suffer side effects from other antihistamines.
