Baclofen is a prescription medication in a class known as skeletal muscle relaxants. It was first introduced in the 1960s as an anti‑seizure drug and later reintroduced in the 1970s for the treatment of muscle spasticity.(Source) Today it is most commonly prescribed to reduce muscle spasms, stiffness, and pain related to conditions such as multiple sclerosis (MS), spinal cord injury, and other neurological disorders.(Source)

Baclofen is available under brand names such as Lioresal and Gablofen, as well as in generic form. It can be given as an oral tablet or liquid, or delivered directly into the spinal fluid through an implanted pump for people with severe spasticity.(Source)

Baclofen acts on the central nervous system, particularly on nerves in the spinal cord, to reduce the abnormal reflexes that cause muscle spasms. It works primarily by activating gamma‑aminobutyric acid type B (GABA‑B) receptors, which inhibit certain nerve signals and help relax muscles.(Source) By dampening these signals, baclofen can decrease involuntary jerking, twitching, and painful muscle contractions that may interfere with walking, balance, and daily activities.(Source)

Because GABA is also involved in anxiety and reward pathways in the brain, researchers have explored whether baclofen’s effects on GABA‑B receptors might also help reduce anxiety, cravings, and compulsive behaviors in conditions such as post‑traumatic stress disorder (PTSD) and substance use disorders.(Source)

Over the past two decades, baclofen has been studied as a potential medication for alcohol use disorder (AUD). Some clinical trials and case reports suggest that baclofen can reduce alcohol cravings, decrease the number of drinks consumed, and support abstinence in certain individuals.(Source)

Baclofen’s possible benefit in AUD appears to come from its action on GABA‑B receptors in the brain’s reward system. By modulating dopamine and other neurotransmitters involved in reinforcement and stress, baclofen may blunt the rewarding effects of alcohol and reduce the anxiety and tension that often trigger drinking.(Source)

However, baclofen does not work the same way for everyone. Studies have found that its effectiveness may be influenced by:

• Co‑occurring mental health conditions such as depression, anxiety disorders, bipolar disorder, or PTSD
• Concurrent use of other psychotropic medications, including benzodiazepines, antidepressants, antipsychotics, mood stabilizers, or stimulants
• Medical conditions that limit how high the dose can be safely increased
• Side effects that make it difficult to reach or maintain a therapeutic dose
• Motivation level and engagement in counseling or behavioral therapies

Because of these variables, most experts view baclofen as a possible adjunct to, not a replacement for, comprehensive treatment that includes therapy, support, and lifestyle changes.(Source)

Baclofen’s role in treating alcohol addiction remains controversial. Interest in high‑dose baclofen for AUD grew after French cardiologist Dr. Olivier Ameisen published his personal account in 2008 describing dramatic reductions in his alcohol cravings while taking baclofen.(Source) His story and subsequent patient reports led to a surge of off‑label prescribing in parts of Europe.

Since then, multiple randomized controlled trials (RCTs) and observational studies have evaluated baclofen for AUD, using a wide range of doses—from about 30 mg per day up to more than 300 mg per day.(Source) For comparison, typical maximum oral doses for spasticity in neurological conditions are around 80 mg per day.(Source)

A 2018 systematic review identified at least 17 randomized controlled trials of baclofen for alcohol dependence, including several high‑dose studies.(Source) Some trials found that baclofen increased rates of abstinence, reduced heavy drinking days, or decreased anxiety compared with placebo, while others showed little or no benefit.

Research from the Netherlands and other countries has raised safety concerns about very high doses of baclofen, noting that evidence for superior effectiveness at these doses is limited and that side effects and serious adverse events become more common as the dose increases.(Source)

One of the largest studies, the French Bacloville trial, enrolled several hundred adults with alcohol dependence and compared flexible‑dose baclofen (up to 300 mg per day) with placebo over one year.(Source) The trial found that baclofen was more effective than placebo in reducing alcohol consumption, but it also reported a higher rate of adverse events and serious side effects in the baclofen group.(Source)

Overall, meta‑analyses published through the mid‑2020s conclude that baclofen may help some people with AUD, particularly those with severe dependence or liver disease who cannot take other medications, but the evidence is inconsistent and the optimal dosing strategy is unclear.(Source) As of 2026, major professional guidelines in the United States do not recommend baclofen as a first‑line medication for AUD, instead prioritizing FDA‑approved options such as naltrexone, acamprosate, and disulfiram.(Source)

Because of the mixed data and safety concerns at higher doses, many clinicians who use baclofen for AUD do so cautiously, at moderate doses, and only as part of a broader treatment plan that includes psychosocial support.(Source)

In the United States, baclofen is FDA‑approved only for the treatment of spasticity related to conditions such as multiple sclerosis and spinal cord injury.(Source) It does not have FDA approval for alcohol use disorder or other addictions as of 2026.(Source)

When a medication is used for a condition that is not part of its official FDA‑approved labeling, this is called “off‑label” use. Off‑label prescribing is legal and common in many areas of medicine, but it requires careful clinical judgment, informed consent, and close monitoring.(Source)

In some European countries, including France, health authorities have issued specific guidance or temporary recommendations for baclofen use in alcohol dependence, often with strict dosing limits and monitoring requirements due to safety concerns.(Source) Even in these settings, baclofen is generally considered a second‑line or alternative option rather than a standard first‑choice treatment.(Source)

If you are considering baclofen for alcohol addiction, it is important to work with a physician who is experienced in addiction medicine, understands the current evidence, and can explain the potential benefits, risks, and alternatives in the context of your overall treatment plan.(Source)

Like all medications that affect the central nervous system, baclofen can cause side effects. Some are mild and temporary, while others can be serious, especially at higher doses or when combined with other sedating substances.

Commonly reported side effects of baclofen include:(Source)

• Drowsiness, dizziness, or feeling sedated
• Fatigue or weakness
• Nausea or upset stomach
• Dry mouth
• Headache
• Insomnia or sleep disturbances
• Constipation
• Low blood pressure (which can cause lightheadedness or fainting)
• Confusion or difficulty concentrating

These effects can impair your ability to drive, operate machinery, or perform tasks that require alertness. The sedative effects of baclofen are significantly increased when it is taken with alcohol, opioids, benzodiazepines, or other medications that depress the central nervous system, raising the risk of falls, accidents, and overdose.(Source)

Less common but more serious side effects can include:(Source)

• Severe drowsiness or unresponsiveness
• Breathing difficulties, especially when combined with other sedatives
• Hallucinations or changes in mood or behavior
• Seizures (particularly in people with a history of seizure disorders)
• Worsening of psychiatric symptoms in some individuals

Baclofen may need to be avoided or used at reduced doses in people with certain medical conditions, such as:(Source)

• Significant kidney disease or reduced kidney function, because baclofen is primarily eliminated by the kidneys
• A history of stroke or brain injury, where central nervous system side effects may be more pronounced
• Epilepsy or seizure disorders
• Neurological conditions like MS where some degree of muscle tone is needed to maintain posture and balance
• Pregnancy or breastfeeding, unless the potential benefits clearly outweigh the risks

Because baclofen can interact with many medications and supplements, it is essential to tell your prescriber about everything you are taking, including over‑the‑counter products and herbal remedies.(Source)

Side effects often improve when the dose is adjusted or increased more slowly. Never change your dose or stop baclofen suddenly without medical guidance.

Baclofen should not be stopped abruptly, especially after long‑term use or at higher doses. Suddenly discontinuing baclofen can lead to a withdrawal syndrome that may be serious and, in rare cases, life‑threatening.(Source)

Reported symptoms of baclofen withdrawal include:(Source)

• Agitation, anxiety, or restlessness
• Insomnia
• Confusion or disorientation
• Hallucinations or psychosis
• Rapid heart rate and high blood pressure
• Fever (hyperthermia)
• Increased muscle spasticity or rigidity
• Seizures

To reduce these risks, clinicians typically recommend “tapering” or titrating the dose down gradually over days to weeks, depending on how long you have been taking baclofen and at what dose.(Source) The same principle applies when starting baclofen: most prescribers begin with a low dose and slowly increase it to allow your body to adjust and to monitor for side effects.

If you miss a dose, do not double up without talking to your provider. If you experience new or worsening confusion, hallucinations, severe anxiety, or seizures while changing your baclofen dose, seek emergency medical care immediately.(Source)

Compared with many other medications that act on the brain, reports of baclofen misuse and addiction are relatively uncommon, but they do occur.(Source) Case reports describe individuals who escalated their doses far beyond what was prescribed, sometimes in an attempt to enhance mood or reduce anxiety, and then developed cravings and withdrawal symptoms when they tried to cut back.(Source)

Because baclofen can produce relaxation, reduced anxiety, or mild euphoria in some people, there is a risk that it may be misused, particularly among individuals with a history of substance use disorders.(Source) Taking more baclofen than prescribed or combining it with alcohol, opioids, or benzodiazepines can be dangerous and may lead to overdose, respiratory depression, or coma.(Source)

Physical dependence—a state in which your body adapts to the presence of a drug and withdrawal symptoms occur if it is stopped too quickly—can develop with long‑term baclofen use, even when taken exactly as prescribed.(Source) Physical dependence is not the same as addiction, which also involves compulsive use despite harm, loss of control, and continued use despite negative consequences.(Source)

To minimize risks:

• Take baclofen only as prescribed and never increase your dose on your own.
• Avoid using baclofen to “self‑medicate” stress, anxiety, or insomnia outside of your treatment plan.
• Store your medication safely and do not share it with others.
• Work closely with your prescriber if you have a history of substance use disorder or mental health conditions.

If you are concerned that you or a loved one may be misusing baclofen, talk with a healthcare professional or an addiction specialist as soon as possible.

No single medication is a cure for alcohol addiction. Alcohol use disorder is a chronic, relapsing condition influenced by genetics, brain chemistry, mental health, environment, and life experiences.(Source) Because of this complexity, effective treatment usually involves a combination of approaches rather than relying on one drug alone.

Even in studies where baclofen has shown benefits, it works best when combined with counseling, behavioral therapies, and ongoing support.(Source) Medications can help reduce cravings, ease withdrawal symptoms, or make drinking less rewarding, but they do not address the underlying emotional, psychological, and social factors that drive addiction.

Evidence‑based treatment for alcohol use disorder often includes:(Source)

• Medical detoxification, when needed, to manage withdrawal safely
• FDA‑approved medications such as naltrexone, acamprosate, or disulfiram, when appropriate
• Individual counseling (for example, cognitive behavioral therapy or motivational interviewing)
• Group therapy and peer support, including 12‑step or alternative recovery groups
• Family therapy and education
• Treatment for co‑occurring mental health conditions, such as depression, anxiety, PTSD, or bipolar disorder
• Aftercare and relapse‑prevention planning, including outpatient therapy, recovery coaching, or sober living

Baclofen may be considered as an off‑label option in specific situations—for example, when first‑line medications are not tolerated or are contraindicated due to liver disease—but it should be part of a comprehensive, individualized treatment plan rather than viewed as a stand‑alone solution.(Source)
