Do You Need Phenobarbital for Alcohol Withdrawal? Complete Guide

Phenobarbital is given to individuals when they are not responding well to standard treatment (benzodiazepines) for alcohol withdrawal. It quickly balances the overactive brain by its dual-action mechanism (enhancing GABA receptor activity and inhibiting glutamate). Its long half-life means fewer peaks and crashes, less frequent dosing, and more stable sedation. 

ChoicePoint offers phenobarbital for alcohol withdrawal as part of its MAT while flushing alcohol out of your system safely. If you are struggling with alcohol withdrawal syndrome (AWS), call 844.445.2565 to schedule your consultation with our licensed professionals today for medically supervised alcohol detox!

What Is Phenobarbital?

• A long-acting medication belonging to the barbiturate class of drugs 
• Treats seizures and extreme cases of epilepsy 
• Helps with mental health diagnoses like insomnia and anxiety
• Best for the emergency department as an immediate care option
• Offered only in inpatient care under medical supervision  
• Medication administration includes intravenous and oral phenobarbital.¹

Why Do We Give Phenobarbital for Alcohol Withdrawal?

Phenobarbital is considered a reliable alternative to standard alcohol withdrawal syndrome (AWS) medications like benzodiazepines because of:

• Long half-life 
• No risk of cross-tolerance 
• Reliable ADME (Absorption, Distribution, Metabolism, and Excretion) processes 
• Dual response to GABA and glutamate receptors²

Medical professionals give phenobarbital to critically ill patients with severe alcohol withdrawal symptoms (shakes, sweating, dehydration, inflammation) to:

• Reduce risk of ICU admission 
• Decrease the duration of hospital stays 
• Eliminate the need for extreme medical procedures like intubation caused by resistance to benzodiazepines
• Manage withdrawal effectively via neural stabilization 

The clinical benefits of phenobarbital administration during alcohol detox make it a viable MAT option.³ However, clinicians deem it unsuitable for outpatient alcohol detox programs due to overdose risks.

Addiction specialists at ChoicePoint can help you find a suitable MAT option based on your alcohol withdrawal timeline and alcohol triggers. Call 844.445.2565 for an online alcohol evaluation to start your recovery journey today! 

How Does Phenobarbital Work for Alcohol Withdrawal?

Gamma-aminobutyric acid is a neurochemical that binds with GABA receptors to calm your nerves. Alcohol is a depressant, so it increases the number of GABA receptors, forcing the body to counter with increased glutamate receptors for a stimulant effect.⁴ 

At this stage, quitting alcohol cold turkey instead of tapering off triggers acute alcohol withdrawal. Phenobarbital for severe alcohol withdrawal helps:

• Inhibit the stimulant effects of glutamate receptors
• Increase the number of GABA receptors 
• Restore the balance to the hyper-sensitive nervous system⁵

If you are looking for a MAT option to quit alcohol safely, ChoicePoint is the top-rated luxury alcohol treatment offering long-term solutions like 30-day inpatient alcohol rehab, as well as step-down options like alcohol outpatient rehab, IOP alcohol treatment, for working professionals. Call 844.445.2565 for details. 

When to Give Phenobarbital for Alcohol Withdrawal?

Phenobarbital is administered as an emergency response at inpatient alcohol rehabs to stabilize patients’ nervous systems. For better clinical outcomes, phenobarbital patients must have an active AWS and be enrolled in:

• ICU (intensive care unit)
• Emergency department 

Individuals who have used lorazepam (20 mg) or its equivalents, diazepam (100 mg), or midazolam (40 mg) in the last 8 or 10 hours should avoid phenobarbital for alcohol withdrawal.⁶ 

When to Use Phenobarbital in Alcohol Withdrawal Safely

How Much Phenobarbital for Alcohol Withdrawal?

The standard phenobarbital loading dose for alcohol withdrawal is 15 mg/kg. It is most effective when followed by a phenobarbital taper in general care. Mixing benzodiazepines with alcohol medication like phenobarbital is inadvisable. Discontinue all benzodiazepines before starting phenobarbital for alcohol treatment. 

Phenobarbital Loading Dose for Alcohol Withdrawal

The table explains the different stages of medical administration:

Clinical Notes

• The phenobarbital loading dose for AWS is based on ideal body weight (IBW). 
• Addiction specialists adjust the dosage based on patients’ actual weight. 
• Intravenous phenobarbital is preferred over intramuscular phenobarbital because of minimal side effects (respiratory depression, overdose risks, and over-sedation).^{7 8}

How Does Phenobarbital Compare to Other Medications for Alcohol Withdrawal?

As an AWS medication, phenobarbital is known for its dual effect on the human nervous system. It has a low risk of relapse and dependency as it is only available for inpatient alcohol rehab under medical supervision. 

If you are looking to eliminate alcohol from your system, it is best to consider all MAT options of alcohol detox for recovery.  

What Is the Difference Between Phenobarbital and Benzodiazepines?

• Benzodiazepines are the standard first-line AWS treatment, whereas phenobarbital is an evolving alternative with minimal withdrawal symptoms. 
• Both medications require medical supervision; however, benzodiazepines have familiar and widely tested protocols. Phenobarbital requires close monitoring, especially during the loading dose.⁹

A detailed comparison table on phenobarbital vs benzodiazepines for alcohol withdrawal is as follows:

Phenobarbital versus Benzodiazepine for Alcohol Withdrawal Syndrome

ChoicePoint offers benzodiazepines for alcohol withdrawal as a first-line treatment for AWS. Our DEA-certified and licensed professionals follow a strict hierarchy of care to ensure safe recovery. Call 844.445.2565 to understand what level of care you need today!

Is Phenobarbital Stronger Than Diazepam?

Yes. Phenobarbital is considered stronger than diazepam for treating alcohol withdrawal syndrome seizures. As a CNS depressant, it has a higher calming effect (enhanced GABA) than diazepam, which helps with seizure intensity.

Despite the benefit, diazepam is the first line of medication for alcohol withdrawal because of its safer administration. Phenobarbital has a narrow therapeutic window, increasing the risk of overdose.¹⁰

Is Phenobarbital Better Than Ativan for Alcohol Withdrawal?

Yes, if you are looking to decrease the duration of your hospital stays and ICU admissions. It also shows better clinical outcomes than Ativan (lorazepam) for the management of AWS, owing to its dual CNS effects. Phenobarbital is also less likely than most benzos to cause respiratory complications under controlled administration.11

How Much Phenobarbital for Alcohol Withdrawal Costs?

Phenobarbital costs up to $20 or less for 30 tablets. Despite the cost, it is only available for inpatient rehab for alcoholism and requires medical supervision. People looking for quick fixes to flush alcohol out of their body cannot use it without clinical guidance.  

Does Insurance Cover MAT for Acute Alcohol Withdrawal?

Yes, almost all commercial insurances cover medication-assisted treatment to manage withdrawal symptoms during alcohol detox. Note that alcohol treatment centers that accept Aetna or any other type of alcohol rehab insurance may vary in:

• Coverage
• Services offered
• Out-of-pocket costs

Usually, insurance benefits for MAT depend on:

• Plan type and monthly premium 
• Medication type and duration
• Prior authorization for usage  
• Medical necessity based on the severity of symptoms 
• Polysubstance disorders 
• Co-occurring mental health issues and alcohol disorders (anxiety disorder substance abuse, post-drinking depression, postpartum depression, and alcohol)

Verify your insurance before accepting any treatment or medication to avoid out-of-pocket expenses. ChoicePoint offers free nationwide insurance verification to help you access the support you need promptly.

Frequently Asked Questions About Phenobarbital for Alcohol Withdrawal 

Find the answers to the most searched questions about phenobarbital and alcohol withdrawal here: 

1. Is there a substitute for phenobarbital?

Yes, there are substitutes for phenobarbital, but usage depends on medical necessity. If you are looking to substitute phenobarbital for alcohol withdrawal, then try benzodiazepines. They are already part of standard treatment for alcohol withdrawal syndrome. 

Phenobarbital also has substitutes as a sleeping medication (Lunesta, Sonata, and Ambien) and as an antiepileptic drug (Gabapentin and Valproic acid). Note that in all usage cases, phenobarbital is never a first-line or standard treatment due to overdose and toxicity risks. 

2. Can someone stop taking pentobarbital after using it for a long time?

No, quitting phenobarbital cold turkey can trigger extreme seizures and respiratory issues. Phenobarbital detox requires medical supervision and a medical taper to minimize health complications. As a scheduled controlled drug, it has addictive potential and should not be used for a long time if there is no medical necessity. 

3. How long does phenobarbital stay in the system?

As a long-acting barbiturate, phenobarbital has a half-life of 3 to 5 days (80 to 120 hours). An adult might take 16 days (compared to 23 days in children) to eliminate a single loading dose from their system. The detection timeline depends on the test and can range from 2 days (swab test) to 7 days (blood test), 15 days (urine test), and 90 days (hair test).¹²
