Clonidine For Anxiety Disorders: Uses, Dosage & Side Effect 2023

Anxiety disorders are a common mental health problem affecting millions of people all over the world. They can manifest in various forms, including Generalized Anxiety Disorder (GAD), Social Phobia, Obsessive-Compulsive Disorder (OCD), and Separation Anxiety Disorder. Panic disorders and Post-Traumatic Stress Disorder (PTSD) also fall under this category.
Anxiety comes with feelings of excessive worry, restlessness, and sleep disturbances can interfere with work, school, relationships, and practically every aspect of your life. These symptoms can make it difficult to navigate everyday tasks and responsibilities. Fortunately, there are certain medications that can help alleviate some of the symptoms associated with anxiety.
Clonidine is among the many pharmacological treatment options being studied for its anti-anxiolytic effects. Emerging evidence suggests its efficacy in addressing certain symptoms of anxiety. If you are considering taking this medication, it is important to have a proper understanding of how it could help, the correct Clonidine for anxiety dose, and its potential side effects.
Clonidine For Anxiety: Does It Work?
Clonidine is primarily used for its antihypertensive effects. It has also been prescribed to treat certain symptoms of anxiety such as PTSD-associated nightmares,[1] insomnia,[2] stress, and agitation.[3] There is very little research supporting the effectiveness of this medication in treating other anxiety symptoms.
Due to the lack of evidence and concerns regarding hypotension and sedation, the practical use of Clonidine in treating patients with anxiety disorders is limited. This medication has been found to be more effective in treating high blood pressure. To find the most appropriate treatment for anxiety management, it is most helpful to consult with a licensed mental health professional.
How Does It Work?
Clonidine works by modulating the activity of norepinephrine, a neurotransmitter in the brain. Norepinephrine is a neurotransmitter that affects blood pressure, heart rate, attention, and arousal. By stabilizing specific brain regions and reducing their excitability, Clonidine can work to decrease feelings of anxiety and improve quality of sleep.
The following strategies can help enhance how Clonidine works for anxiety disorders:
- Discover techniques to deal with stress, like practicing meditation and looking into different types of therapy.
- Prioritize sleep. Find the best sleeping position for anxiety that works for you. If you continue to have trouble sleeping, it is best to speak with your doctor about it.
- Psychotherapy or talk therapy can help reduce anxiety and improve the effectiveness of your medication. Get affordable online therapy.
- Join groups online or offline where people with anxiety problems talk about their experiences and ways to deal with them. Talkspace reviews can help you locate one.
- Exercise frequently and consume a nutritious, well-balanced diet.
What Is Clonidine?
Clonidine is classified as an imidazole or central alpha agonist because of its effect on the central nervous system. Drug companies usually package Clonidine in different forms, such as extended release tablets, immediate release tablets, transdermal patches, and liquid solutions. The medicine is also available as a cream and injection.
Clonidine can be found under several brand names including:
- Catapres.
- Catapres-TTS.
- Kapvay.
- Duraclon.
- Nexiclon XR.
In addition to hypertension and anxiety, Clonidine may also have potential benefits for conditions such as:
- Attention Deficit/ Hyperactivity Disorder (ADHD).
- Opioid withdrawal.
- Post-traumatic stress disorder (PTSD).
- Tourette’s syndrome.
- Menopause.[4]
- Migraine headaches.
- Diabetic neuropathy.
Clonidine Dosage For Anxiety
It is important to seek guidance from a licensed medical professional to know the appropriate dose of clonidine for anxiety. Dosage will highly depend on each individual’s unique response to the drug. When it comes to finding the right dosage for you, you may require frequent adjustments along the way.
Clonidine Oral Tablets
There are two types: immediate-release and extended-release tablets. Clonidine tablets are available in three strength levels: 0.1mg, 0.2mg, and 0.3mg. The extended release usually comes in 0.1 mg tablets.
It’s common for adults to take a Clonidine dose for anxiety ranging from 0.1mg to 0.4mg, once or twice daily. The usual starting dose of the extended release tablet is 0.1 mg, taken twice daily. If you believe Clonidine might be beneficial in addressing your anxiety symptoms, it’s important to consult with your doctor to ensure that it is a safe and suitable treatment option for you.
Clonidine Transdermal Patches
The transdermal Clonidine patch is typically applied to the skin once a week for continuous medication delivery. Individuals who take multiple oral medications daily may opt for Clonidine patches as an alternative to help reduce their medication load. For the drug to be absorbed the most effectively, place the patch on the chest or upper arm area.
