From the Guidelines
Semaglutide is not currently FDA-approved for treating alcoholism, though emerging research suggests it may help reduce alcohol consumption in some individuals. Semaglutide (brand names Ozempic, Wegovy, Rybelsus) is a GLP-1 receptor agonist primarily approved for type 2 diabetes and weight management 1. Some patients taking semaglutide have reported decreased interest in alcohol, and preliminary studies indicate it may reduce alcohol cravings by affecting reward pathways in the brain and reducing the dopamine response to alcohol.
Key Points to Consider
- The typical dosing for semaglutide starts at 0.25mg weekly by injection, gradually increasing to 1.0-2.4mg weekly depending on the indication, though no established protocol exists specifically for alcohol use disorder.
- Side effects include nausea, vomiting, diarrhea, and constipation.
- Anyone considering semaglutide for alcohol reduction should consult their healthcare provider, as this would be an off-label use requiring medical supervision.
- Traditional FDA-approved medications for alcohol use disorder include naltrexone, acamprosate, and disulfiram, which remain the standard treatments alongside behavioral therapy and support groups 1.
Important Considerations for Treatment
- The management of alcoholic liver disease is critical, and identifying hazardous drinkers is essential to prevent or slow the progression of the disease 1.
- Alcohol use disorder is diagnosed based on psychological, social, and physical problems, and disability caused by alcohol consumption in the past 12 months, rather than on the amount of alcohol consumed or the drinking habit.
- The APA’s Diagnostic and Statistical Manuals of Mental Disorders, 4th Edition (DSM-IV) divides alcohol use disorder into two categories: alcohol abuse and alcohol dependence, while the recently revised DSM-V defines it as mild, moderate, or severe based on the severity.
From the Research
Semaglutide and Alcoholism
- Semaglutide, a glucagon-like peptide-1 receptor agonist, has been studied for its potential effects on alcohol consumption and craving in adults with alcohol use disorder (AUD) 2.
- A phase 2, double-blind, randomized, parallel-arm trial found that low-dose semaglutide reduced the amount of alcohol consumed during a posttreatment laboratory self-administration task, with medium to large effect sizes for grams of alcohol consumed and peak breath alcohol concentration 2.
- Semaglutide treatment also significantly reduced drinks per drinking day and weekly alcohol craving, and predicted greater reductions in heavy drinking over time relative to placebo 2.
- The study suggests that semaglutide may be a potential treatment for alcohol use disorder, but larger clinical trials are needed to evaluate its effectiveness 2.
Mechanism of Action
- Semaglutide's mechanism of action is thought to involve its effects on glucose and lipid metabolism, as well as its anti-inflammatory and anti-neuroinflammatory properties 3, 4.
- These effects may contribute to its potential benefits in reducing alcohol consumption and craving, although the exact mechanisms are not fully understood 2.
Safety and Efficacy
- Semaglutide has been shown to be effective in improving glycemic control, weight loss, and reducing cardiovascular risks associated with diabetes mellitus 5, 3, 4, 6.
- However, it is also associated with potential adverse effects, such as acute pancreatitis, anesthetic risks, acute kidney injury, and diabetic retinopathy 5, 3.
- The safety and efficacy of semaglutide for the treatment of alcohol use disorder are still being studied, and more research is needed to fully understand its potential benefits and risks 2.
