Melatonin Side Effects in Dogs
Melatonin is the active ingredient in the brand name Melatonex. It's usually given to dogs with epilepsy, hyperactivity or severe anxiety problems, such as panicking during thunderstorms. Sometimes it's also given to older dogs with dementia that may be awake all night. This is a human drug that is currently not approved for use in dogs, but many veterinarians prescribe it as an off-label use.
