Overview of Clomipramine (Clomicalm®) for Dogs and Cats
- Clomipramine, also known by the brand names of Clomicalm® and Anafranil®, is approved for the treatment of canine behavioral disorders classified as separation anxiety. It has also been used to modify owner-directed dominance aggression in dogs. Clomipramine is also used in cats for urine spraying.
- Behavioral disorders in dogs and cats are a common reason for veterinary visits. Unacceptable or dangerous animal behavior problems may lead some owners to elect euthanasia as an ultimate solution to the problems they face with their pets.
- Recently, veterinarians have placed greater emphasis on proper training and behavior modification practices, and specialists working in the field of animal behavior have increasingly adopted drugs used in human behavior for animal use. Clomipramine is one of these drugs, and one of the very few specifically approved for use in dogs.
- Clomipramine belongs to a class of drugs known as tricyclic antidepressants. It is thought to have effects on serotonin, an important “chemical messenger” found within the brain.
- Clomipramine is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
