Baclofen and Alcohol: What You Need to Know

baclofen and alcohol

This article will explore the relationship between baclofen and alcohol. Baclofen is a nervous system depressant and muscle relaxant that is widely prescribed for spasticity disorders:

  • Spinal cord injuries
  • Cerebral palsy
  • Multiple sclerosis

Yet over the past decade, an increasing number of people have used baclofen for alcohol withdrawal and alcohol cravings.

This phenomenon can be traced to the experience of Dr. Olivier Ameisen, who discovered and studied baclofen and alcohol in the early 2000s. Dr. Ameisen used high-dose baclofen to transform himself from a fifth-a-day alcoholic into a teetotaler with no cravings.

Can Baclofen Be Taken With Alcohol?

Some research has shown that heavy social drinkers tolerate baclofen well in combination with alcohol. One study states that, “Baclofen alone has minimal abuse liability in heavy social drinkers and baclofen is relatively well tolerated and safe when given in combination with intoxicating doses of alcohol.” ()

However, there have been case reports of people experiencing serious side effects from mixing baclofen and alcohol, including seizures. (source) Baclofen and alcohol both act on the same neurotransmitter systems, meaning that side effects from taking either may be more pronounced in combination.

Since baclofen may prove useful in ameliorating alcohol withdrawal, it’s best to use a minimum effective dosage while attempting to quit drinking rather than combining them. Combining baclofen and alcohol for recreational purposes is not recommended.

How does baclofen work for alcohol withdrawal?

Like alcohol and benzodiazepines, baclofen activates GABA receptors in the brain. GABA is an inhibitory neurotransmitter associated with feelings of calm. The difference with baclofen is that it activates GABA-B receptors rather than GABA-A receptors.

  • Alcohol – Stimulates GABA-A and GABA-B receptors
  • Benzodiazepines – Stimulates mainly GABA-A receptors
  • Baclofen – Stimulates mainly GABA-B receptors

Baclofen is structurally very similar to phenibut, another GABA-B receptor agonist, which is available in the U.S. as a supplement. The only difference is that baclofen contains a chlorine atom.

What really makes baclofen unique is that dosage tolerance does not seem to build up over time to any significant degree.

For example, a patient that responds well to 40 mg per day of baclofen is likely to obtain the same benefit from the same dosage several years from now.

Most alcoholics know from experience that the amount of alcohol needed to achieve a buzz increases over time. Eventually, the amount of alcohol needed just to prevent alcohol withdrawal symptoms exceeds the body’s ability to repair itself from all of that alcohol.

Under a doctor’s supervision, an alcoholic who quits drinking with the help of baclofen can prevent withdrawal symptoms.

If the patient takes baclofen for a long period of time or indefinitely, the cravings that torture so many so -called “recovering alcoholics” for years can be extinguished.

Because baclofen has anticraving effects, some people even find that they can return to moderate drinking while on long-term baclofen treatment. Many of them find that they simply don’t feel compelled to drink anymore.

baclofen and alcohol

American doctors sometimes refuse to prescribe baclofen for alcohol cravings because there have been no large-scale clinical trials showing that baclofen is effective for alcoholism.

These trials do not exist because baclofen is an old generic drug that cannot be patented. While there are several different brands of baclofen available, there is no incentive for drug companies to spend money on these trials.

In Europe, however, there is a less dismissive attitude toward baclofen.

Over 50,000 people in France are currently taking high-dose baclofen for alcohol disorder treatment.

Like most GABA agonists, baclofen can cause dependence. Patients who have successfully used baclofen for alcohol disorders sometimes take it for the rest of their lives. Others use baclofen primarily for alcohol withdrawal symptoms and then wean off of baclofen slowly.

Dr. Olivier Ameisen’s Story

The relationship between baclofen and alcohol was a serendipitous discovery made by a doctor looking for ways to extinguish the desire to drink.

Dr. Ameisen was a brilliant French-American cardiologist who had suffered from all of the worst symptoms of alcohol addiction. He’d cancelled meetings due to withdrawal anxiety, broken bones during blackouts, and suffered from massive withdrawal-related seizures.

Interestingly, Dr. Ameisen tried the Sinclair Method and reported that it did not work for him.

He continued his search for a cure and eventually found that with the right dose of baclofen, he no longer suffered from alcohol withdrawal symptoms or cravings.

His most controversial finding was that he could take or leave alcohol if he wanted to.

Dr. Ameisen passed away from a heart attack in 2013.

You can read more about Dr. Ameisen’s story, and more about baclofen and alcohol, in his book: The End of My Addiction.

Baclofen For Alcohol Withdrawal

The following information may prove useful if you are considering taking baclofen for alcohol withdrawal:

  • While everyone is different, typically baclofen for alcohol withdrawal treatment lasts no longer than a week.
  • Since the half life of baclofen is only 4 hours, multiple doses are taken each day.
  • Most people begin with 40 mg, and then increase by 20 mg per dose as needed.
  • 40-80 mg per day (in divided doses) of baclofen for alcohol withdrawal is typically effective to mitigate symptoms.
  • For spasticity disorders, up to 300 mg per day of baclofen is commonly used without problems.
  • Only take baclofen under the supervision of a doctor.

Before taking baclofen for alcohol withdrawal, make sure to review the following:

Baclofen For Alcohol Cravings

The long-term use of high-dose baclofen for alcohol cravings may cause dependence on baclofen. Many people find that this is an acceptable trade-off for two reasons:

  • After trying everything else, baclofen finally ends their alcohol cravings and relapses
  • Baclofen tolerance does not typically increase over time

Dr. Ameisen’s dosing schedule is typically used for individuals who use baclofen for alcohol cravings:

  • 30 mg of baclofen per day, adding 20 mg every third day.
  • Within 5 weeks, he reached 270 mg per day (in divided doses).
  • At 270 mg per day, Dr. Ameisen found he became totally indifferent toward alcohol.
  • Once he reached this dose, he maintained it for 12 days, and then gradually cut down to 120 mg per day for a long time.
  • He eventually cut his dose to 30-50 mg per day, which he then maintained until the end of his life.
  • The optimal dosing strategy may be different for everyone due to biochemical individuality.

Dangers of Mixing Baclofen and Alcohol

Despite limited research showing that baclofen and alcohol are well tolerated together, serious side effects are always possible when combining alcohol with prescription medications.

Care should always be taken to avoid alcohol while taking medications that target the GABA system. These drugs include baclofen along with benzodiazepines, barbiturates, and sleep medications including Ambien.

Side effects from mixing baclofen and alcohol may include:

  • Muscle weakness
  • Extreme fatigue
  • Confusion
  • Loss of balance
  • Agitation

What can you not take with Baclofen?

Drugs that should not be taken with baclofen include:

  • Opioid pain relievers
  • Codeine
  • Marijuana
  • Benzodiazepines
  • Zolpidem (Ambien)
  • Muscle relaxants (carisoprodol, cyclobenzaprine)
  • Antihistamines (cetirizine, diphenhydramine)

Research Studies

baclofen and alcohol

The effectiveness of baclofen for alcohol withdrawal and alcohol cravings is now well-established in the scientific literature:

  • In a two-year study of 100 patients, long-term baclofen treatment caused an effortless decrease of alcohol withdrawal and post-acute withdrawal symptoms (source)
  • In a 12-week study of 56 alcoholic patients receiving either high dose baclofen or a placebo, 68% of those given baclofen remained abstinent, compared to 23% on the placebo (source)
  • High-dose baclofen produces a “remarkable state of indifference to alcohol” (source)
  • Baclofen reduces the severity of relapses and extinguishes alcohol cravings through its action on GABA-B receptors (source)

Interestingly, baclofen seems to work best for individuals with the worst cases of alcoholism.

Dr. Ameisen could attest to this, and this finding has even been replicated in baclofen studies with alcoholic rats:

“Data from alcohol self-administration studies suggest that treatment with non-sedative doses of baclofen effectively reduced—beside alcohol consumption—the reinforcing and motivational properties of alcohol. Since operant procedures of alcohol self-administration in rodents possess predictive validity for human craving for alcohol (see Markou et al., 1993), these data bear translational relevance. In terms of translation “from lab bench to bedside,” it may be worth noting that baclofen resulted to be more potent and effective in those rats (either selectively bred or made physically dependent on alcohol) seeking and taking larger amounts of alcohol (Walker and Koob, 2007; Maccioni et al., 2012).”

Further Considerations

Here are some other things to consider before using baclofen for alcohol withdrawal or alcohol cravings:

  • Because we are all biochemically different, some people do not respond well to baclofen.
  • Even if baclofen works for you, make sure you have support and that you repair your body proactively! Nutrient deficiencies can contribute to health problems down the road.
  • Regardless of how you quit drinking, it helps to renew your sense of purpose in life.

Like the Sinclair Method, the use of baclofen for alcohol disorders is a little-known but highly effective treatment that our medical establishment has all but hidden from patients.

While not everyone responds well to baclofen, I believe that greater awareness of baclofen can improve recovery odds for chronic relapsers and individuals who do not benefit from traditional recovery methods.

There is no one-size-fits-all approach for alcohol detox and recovery. Most people who quit drinking are not enlightened about nutrient repair, pharmacological options like Sinclair or baclofen, or any holistic strategies for improving quality of life.

Hi Mehdi, I’m not aware of any interactions between these two compounds! To be sure, you can ask your doctor who prescribed baclofen about it. Good luck to you!

Hey so, I’ve read this 3x. Is Bsclofen for acute alcohol withdrawals (aka interchagable with benzos) is it this a longer term solution for reducing cravings and become “indifferent” to alcohol over time. Thank you~~!! 🙂

Hi Michael, there are doctors who have successfully prescribed baclofen for acute withdrawal, although benzodiazepines are still preferred, especially in severe cases. In Europe, baclofen is often used long-term with the goal of becoming indifferent to alcohol – and this is the method that Dr. Ameisen used himself and promoted.
