What Is Clonidine?

What Is Clonidine?

Clonidine is a prescription medicine commonly classified as a centrally acting alpha-2 adrenergic agonist used for the treatment of hypertension (high blood pressure). It is also used to manage attention-deficit/hyperactivity disorder (ADHD) in children when using extended-release formulations.

Clonidine lowers blood pressure by activating alpha-2 receptors in the brain, which reduces sympathetic nervous system activity. It can also help manage certain neurological symptoms associated with these conditions.

Clonidine is available in various forms and strengths approved by the FDA. Currently, our pharmacy provides 0.1 mg and 0.2 mg immediate‑release tablet strengths. It should only be used with a valid prescription from a licensed healthcare provider.

What Is the Drug Clonidine Used For?

What Is the Drug Clonidine Used For?

Clonidine is an FDA-approved prescription medication used to treat:

  • Hypertension (immediate‑release tablets and transdermal patch)
  • ADHD (Attention‑Deficit/Hyperactivity Disorder) in adolescents and children ≥6 years (extended‑release tablets)

Other off-label uses, such as opioid or nicotine withdrawal, or certain pain conditions, are not FDA‑approved indications. These uses should only occur when specifically recommended and closely supervised by a licensed physician or healthcare provider.

What Is the Mechanism of Action of Clonidine?

What Is the Mechanism of Action of Clonidine?

Clonidine tablets work as a centrally acting alpha-2 adrenergic agonist. Clonidine stimulates alpha‑2 receptors in the brain, reducing sympathetic nervous system activity. This slows heart rate, relaxes blood vessels, lowers blood pressure, and reduces cardiac stress. In ADHD, Clonidine’s calming effect on the central nervous system helps improve attention, impulse control, and hyperactivity.

The following information outlines important precautions, warnings, and situations in which Clonidine use may require caution or be inappropriate:

  • Always follow your doctor’s instructions and consult your provider before making any changes to your dosage regimen.
