Selegiline for Dogs
Selegiline is used to treat canine cognitive dysfunction associated with aging. Symptoms of brain aging in the dog include loss of responsiveness, alterations in general awareness, memory loss, and loss of previously learned behaviors. Selegiline works by increasing dopamine levels in the brain. This drug is used in human medicine to treat Parkinson’s disease. It may take up to a month before you see any real change or improvement in your pet’s cognitive status, and there may be continued gradual improvement over time. Selegiline does not cure canine cognitive dysfunction but can improve quality of life for your pet. Selegiline is also used to treat some forms of Cushing’s disease in the dog.
Selegiline is FDA approved for use in the dog but it has not been FDA approved in the cat. When the appropriate form or dose of this drug is not available through a veterinary pharmaceutical manufacturer, it may be compounded by a specialty pharmacy.
