About Clonidine

Clonidine is considered an antiadrenergic agent, or an alpha blocker, which helps lower blood pressure by decreasing the levels of certain chemicals in your blood. In turn, your blood vessels relax, and your heart can beat more easily.

Clonidine is a generic prescription drug used to treat high blood pressure (hypertension). The brand name Catapres also has the active ingredient clonidine.

Kapvay, another brand of clonidine, may be prescribed in young children to treat attention deficit hyperactivity disorder (ADHD). Although the exact mechanism is unknown, there’s something about the relaxation of blood vessels in that manner that can lead to a calming and focusing effect in children.

Clonidine may be prescribed as an oral tablet, oral suspension, transdermal patch, or extended-release tablet. In hospital settings, it can also be provided as an injection. Always follow your doctor's specific instructions on your prescription.

If you are prescribed clonidine, be sure to take as directed unless your doctor specifically tells you to stop. Stopping clonidine will result in a return of symptoms, as both high blood pressure and ADHD are chronic conditions.
