Clonidine
In StockClonidine is a prescription medicine used to treat high blood pressure (hypertension) and may also be prescribed for certain conditions involving the nervous system, such as attention-related disorders or withdrawal symptoms. It works by stimulating specific receptors in the brain that reduce nerve signals controlling blood vessel tension, helping lower blood pressure and heart workload. Use as directed on the product label or by a healthcare professional.
What is Clonidine?
Clonidine is a prescription medication used to treat high blood pressure and certain other medical conditions. It belongs to a class of medicines called **centrally acting alpha-2 adrenergic agonists**.
Drug Class
* Alpha-2 adrenergic agonist (central acting antihypertensive)
Approved Uses
Clonidine is commonly prescribed for:
* High blood pressure (hypertension)
* Attention-deficit/hyperactivity disorder (ADHD) (extended-release form)
* Management of withdrawal symptoms (such as opioid withdrawal)
* Certain pain or anxiety-related conditions (in selected cases under specialist supervision)
Available Formulations and Strengths
Clonidine is available in:
* Oral tablets (immediate-release)
* Extended-release tablets
* Transdermal patch (applied to the skin)
Tablet strengths may include:
* 0.1 mg
* 0.2 mg
* 0.3 mg
Patches are available in different weekly delivery strengths.
The specific form and strength depend on the condition being treated.
What is the Recommended Dosage of Clonidine?
Clonidine dosing varies based on:
* The condition being treated
* Age
* Body weight (especially in children with ADHD)
* Kidney function
* Response to treatment
It may be taken once or multiple times daily depending on the formulation. The transdermal patch is typically changed once weekly.
Important Dosing Principles
* Treatment often starts at a low dose.
* Doses are increased gradually if needed.
* Blood pressure and heart rate must be monitored.
* Clonidine must not be stopped suddenly, as this may cause a rapid rise in blood pressure (rebound hypertension).
Exact dosing must follow specialist instructions. Never adjust or stop the medication without medical supervision.
How Clonidine Works
Clonidine works by stimulating alpha-2 receptors in the brain. These receptors help control signals that regulate blood pressure and heart rate.
When clonidine activates these receptors:
* The brain sends fewer signals that tighten blood vessels.
* Blood vessels relax.
* Heart rate may slow.
* Blood pressure decreases.
In ADHD, clonidine may help regulate certain brain pathways involved in attention and impulse control.
Clonidine helps manage symptoms but does not cure high blood pressure or ADHD.
