Baclofen

Baclofen is sometimes used off-label to support alcohol abstinence. Its evidence is mixed across outcomes, and sedation, kidney function and serious withdrawal risks make careful clinical review essential.

Baclofen is a medicine used to reduce muscle spasticity and is also considered in some alcohol-treatment plans. Its alcohol use is often off-label. Research suggests it can help with maintaining abstinence in some circumstances, but findings differ across outcomes and do not establish that it reliably removes craving or anxiety.

It can cause sleepiness, dizziness or weakness. Alcohol, opioids and other sedating medicines can increase the risk of dangerous sedation and breathing problems. Slow or difficult breathing, a seizure, collapse or an inability to wake after possible medicine or substance exposure requires emergency medical help. Sudden confusion needs immediate medical help.

Kidney function matters because baclofen leaves the body largely through the kidneys. Interest in its use for people with liver disease does not make it safe for everyone with liver disease or remove the need for an individual assessment.

Do not abruptly stop or change baclofen on your own. Withdrawal can be serious, including hallucinations and seizures. Contact the prescriber about gaps, unwanted effects or a wish to stop. New suicidal thoughts need prompt support and clinical review; immediate danger requires emergency help. Baclofen is not a substitute for medically assessed alcohol-withdrawal care. If physical alcohol dependence may be present, seek medical advice before suddenly stopping or sharply reducing drinking.
