Cannabidiol (CBD)

What is cannabidiol?

Cannabidiol, also known as CBD, is a naturally occurring cannabinoid (a compound found in the Cannabis plant). Cannabidiol is used as an analgesic (pain reliever) and anticonvulsant. It is used to treat osteoarthritic pain and to help control seizures in dogs and other species. Cannabidiol should only be given under the direction of a veterinarian. Some products contain ingredients other than cannabidiol that may be harmful to your pet – discuss product selection with your veterinarian.

It is used “off label” or “extra label” in animals. Many drugs are commonly prescribed for off-label use in veterinary medicine. In these instances, follow your veterinarian’s directions and cautions very carefully.

How do I give my pet cannabidiol?

Cannabidiol comes in a variety of forms, including capsule, tablet, and liquid suspension.

This medication will take effect quickly, in about 1 to 5 hours. It is short-acting, meaning that effects should stop after 24 hours, though effects may be prolonged in pets with liver disease.

What if I miss giving my pet the medication?

Give the missed dose as soon as you remember and then continue with the regular dosing schedule. If it is almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not give the pet two doses at once.

Are there any potential side effects from cannabidiol?
