Patient Education: Clonidine

Clonidine is prescribed by your healthcare provider based on current guidelines to address specific mental health conditions. While effective, all medications have potential side effects. It's crucial to be informed about these risks and benefits. It's also important to understand strategies to reduce their occurrence or manage them effectively. It's vital to know when to contact your healthcare provider or seek immediate medical attention. This guide aims to empower you with this knowledge, ensuring a well-informed approach to your child's treatment. If you are still unsure, always reach out to your healthcare provider for further guidance.

What is Clonidine?

Clonidine belongs to a group of medicines known as alpha-2A adrenergic receptor agonists. It works by stimulating these receptors in the brain, which helps the brain manage signals better. This makes it easier to concentrate and control impulses.

Your doctor may prescribe Clonidine  for:

• Attention Deficit Hyperactivity Disorder (ADHD)
• Insomnia, especially in children with ADHD

What can be the possible

side-effects from the medication?

Your child may experience some side effects from the medication initially. Most of these side effects are mild and improve over time. The medication is started at a low dose to minimize these side effects. If side effects persist, consult your healthcare provider.
