How Much Clonidine Should I Take For Opiate Withdrawal?

Usually, people go for the traditional drugs for Opiate withdrawal like Naloxone and Naltrexone, but now people have discovered various other medications for Opiate withdrawal.

One of these drugs is Clonidine. It is the drug of choice for hypertension and attention deficit hyperactivity disorder (ADHD), but now people take it for Opiate withdrawal too.

In this article, we will understand how clonidine can help with Opiate withdrawal, its mechanism of action, duration of action, dosage, contraindications, and complications. Let’s have a look at the article.

What is Clonidine?

What is ClonidineClonidine is a drug that acts by lowering the blood pressure and treating the symptoms of ADHD. It is also helpful in anxiety disorders, withdrawal from Opiates, alcohol or smoking.

It also helps in ailments like a migraine, diarrhea, menopausal flushing and chronic pain. It is an alpha2 adrenergic agonist as well as imidazoline receptor agonist.

It stimulates the alpha2 receptors, and this helps in decreasing the peripheral vascular resistance, thus lowering blood pressure.

This is achieved as the binding of clonidine to alpha2 receptors inhibits the release of norepinephrine which is responsible for vasoconstriction and elevation of systemic blood pressure.

It increases the noradrenergic tone of the prefrontal cortex, and this is how it alleviates the symptoms of ADHD.

What is Opiate withdrawal?

What is Opiate withdrawalFrequent consumption of large doses of Opiates results in Opiate addiction.

This occurs as the body gets accustomed to the exogenous supply of Opiates and for its normal functioning it requires a continuous supply of Opiates.

If the Opiates are not taken, the body goes into a state of withdrawal. Opiate withdrawal occurs due to sudden cessation of Opiates leading to specific complications.

Now that we know that the body is dependent on Opiates which means it will only produce dopamine, serotonin and sympathetic neurotransmitters in the presence of Opiates, the person starts experiencing symptoms.

No dopamine means the person will feel low. No enkephalins, endorphins, and dynorphins mean he will begin to have cramps and pain. No sympathetic discharge means lethargy and easy fatigability.

The patient presents with a complaint of constipation, aggression, runny nose, irritability, depression and increased lacrimation.

How does, Clonidine help with Opiate withdrawal?

Clonidine is not a narcotic. It acts by reducing the noradrenergic hyperactivity that is associated with Opiate withdrawal. It alleviates the symptoms of anxiety and agitation.

It doesn’t mitigate cravings for Opiates. It also helps in reducing muscle cramps, sweating and runny nose. It helps in lowering the Opiate withdrawal symptoms without causing tolerance or dependence.

During the Opiate withdrawal phase, the patient experiences both physical and psychological symptoms which can be alleviated by clonidine without extending the detox period from more than two weeks.

This is in contrast to methadone and buprenorphine which continue the detox process. Clonidine acts by lowering heart and blood pressure thus reducing the sensation of anxiety and improving attention.

It suppresses impulsivity and enhances mood. Clonidine, however, is not effective in treating withdrawal symptoms like muscle aches, insomnia and physical craving for Opiates.

Peak clonidine doses are administered on the second, third and fourth day. The daily regimen of oral Clonidine dosage is stated below;

Day 1: 0.1 to 0.2mg of oral clonidine every 4 hours. Total clonidine intake per day=1mg

Day 5 to completion of detox process: Reduce your dose 0.2mg daily. The night time dose should be reduced at last.

If you are using Clonidine patch you can use any of the three types; #1, #2 and #3. It delivers clonidine over a period of 1 week. #2 patch is equal to 0.2mg oral clonidine.

If the patient is under 100lbs apply one #2 patch. If the patient is over 100lbs, use #2 two patches and if the patient is over 200lbs apply #2 three patches.
