Overview

Clonidine is a prescription medication primarily used to treat high blood pressure (hypertension). It is also prescribed for attention deficit hyperactivity disorder (ADHD), certain pain conditions, and withdrawal symptoms from opioids or alcohol. Available in oral tablet and transdermal patch forms, clonidine works by affecting specific receptors in the brain to reduce heart rate and relax blood vessels. Clonidine is often prescribed as a standalone treatment or in combination with other medications. Its use requires professional medical supervision because of potential side effects and interactions. The dosage and form of administration depend on the condition being treated and individual patient factors. It is essential to adhere strictly to a healthcare provider's instructions when using clonidine.
