About Clonidine
Clonidine is considered an antiadrenergic agent, 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).
Clonidine may be prescribed as an oral tablet, injectable solution, oral suspension, transdermal patch, or extended-release tablet. Always follow your doctor's specific instructions on your prescription.
If you are prescribed clonidine, be sure to complete the full course of medication unless your doctor specifically tells you to stop. If you don’t complete your prescription, your symptoms won't be treated.
