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.

Clonidine is an FDA-approved prescription medication used to treat:
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.
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.
Clonidine dosage depends on the indication, patient age, and formulation. Always follow your doctor’s instructions exactly.
| Indication | Formulation | Typical Starting Dose | Titration / Max Dose | FDA Notes |
|---|---|---|---|---|
| Hypertension (Adults) | Immediate‑release tablets | 0.1 mg twice daily | Increase by 0.1 mg/day at weekly intervals; usual range 0.2–0.6 mg/day divided | Monitor blood pressure and heart rate; taper gradually to avoid rebound hypertension |
| Hypertension (Transdermal Patch) | Weekly patch | 0.1 mg/day patch applied once weekly | May increase to 0.2 or 0.3 mg/day patch | Provides smoother BP control; rotate application sites |
| ADHD (Children ≥6 years) | Extended‑release tablets | 0.1 mg at bedtime | Increase by 0.1 mg/day at weekly intervals; max 0.4 mg/day (divided doses) | Approved for children ≥6 years; monitor for sedation and hypotension |
| Off‑label Uses (withdrawal syndromes, pain adjunct) | IR tablets | Variable, typically 0.1 mg 2–3 times daily | Adjust based on clinical response | Not FDA‑approved; use only under specialist guidance |
