GLP-1 Drugs Offer Real Hope for People With Pain or Addiction

By Dr. Lynn Webster

In Greek mythology, the goddess Panacea carried a potion that could heal any disease. It’s a seductive image, and it’s how GLP-1 drugs can start to feel as reports pile up about their potential in treating conditions besides diabetes and obesity.

A recent Washington Post article alludes to Panacea before describing the emerging signs that people living with pain or addiction might benefit from GLP-1s.  

The promise is real. So are the risks. If GLP-1s are going to move from metabolic medicine into the worlds of pain and substance use disorders, we should talk about them the way we would talk about any powerful new class: with evidence, not mythology.

What We Know About GLP-1s and Pain

The most solid pain evidence so far involves knee osteoarthritis — a condition where weight, inflammation, and function are tightly linked. In a 68-week placebo-controlled trial, once-weekly semaglutide (Ozempic, Wegovy) injections in people with obesity and moderate knee osteoarthritis produced significantly greater reductions in body weight — along with significant improvements in pain scores and better physical function.  

That is meaningful. But it doesn’t automatically make semaglutide a “pain drug.” Weight reduction can relieve joint pain, and metabolic improvements may dampen inflammation. Researchers are still sorting out what portion of the pain relief is caused by weight loss alone.  

Outside osteoarthritis, the evidence is thinner. Preclinical studies suggest GLP-1 receptor agonists may reduce neuropathic pain through anti-inflammatory and neuroprotective effects.  

One promising real-world signal comes from fibromyalgia. A large analysis of over 96,000 patients found GLP-1 use associated with significantly lower odds of needing an opioid prescription or of being diagnosed with chronic pain and/or fatigue.   

These observational data are hypothesis-generating, but require confirmation in future studies. More rigorous randomized trials for fibromyalgia, diabetic neuropathy, and other chronic pain syndromes are needed.

What We Know About GLP-1s and Addiction

Here the signal is surprisingly strong — but still preliminary. The evidence so far suggests that GLP-1s appear to modulate reward pathways in the brain that shape craving and compulsive drug use.

A large 2026 observational study of over 600,000 U.S. veterans with type 2 diabetes found that GLP-1s were associated with lower risk of developing substance use disorders (SUDs) involving alcohol, cannabis, cocaine, nicotine or opioids. Among those with preexisting SUDs, GLP-1s were linked to lower risks of emergency room visits, hospitalizations, mortality, overdose, and suicidal thoughts or attempts.

Observational data can’t prove causation, but the consistency across substances and outcomes provides a strong rationale for clinical trials.

We also have randomized evidence in alcohol use disorder. A small Phase 2 trial of 48 adults with alcohol use disorder found that once-weekly semaglutides reduced drinking and cravings over nine weeks compared with placebo.

More research is underway. A recent systematic review identified 33 registered trials looking at GLP-1s for SUDs, predominantly for alcohol and nicotine, but with growing interest in opioid and stimulant SUDs.  

The Risks We Can’t Minimize

The common side effects of GLP-1s — nausea, vomiting, diarrhea, constipation and appetite suppression — are often manageable, but they can be therapy-ending. That matters, because many GLP-1 benefits appear to fade when treatment stops.

In pain and addiction care, “stop-start” patterns are common when insurance coverage shifts or supply is disrupted. Those interruptions are often risky.

A 2026 Washington University School of Medicine analysis of veterans with type 2 diabetes found that even brief interruptions of GLP-1 treatment -- as little as six months -- were associated with higher risk of heart attack, stroke, and death compared with continuous use. The risks rise even further the longer the gap, with up to 22% higher risk of a major cardiovascular event after two years off therapy.  

More concerning are rare but serious complications. Reports of severe delayed gastric emptying (stomach paralysis) remain a clinical concern. Cohort studies have also reported an association between semaglutides and neuropathy in patients with diabetes, although causality remains debated and the absolute risks are low.  

Emerging observational data have raised questions about musculoskeletal safety, with special relevance for people already limited by pain. Some analyses link GLP-1 use to modest reductions in bone mineral density and possible increases in osteoporosis or fracture risk in older adults. Tendon injuries have also appeared in some patients with obesity.  

These findings need replication. Because GLP-1s can slow stomach emptying, clinicians must plan around procedures. The American Society of Anesthesiologists recommends individualized perioperative strategies, including temporary liquid diets for some higher-risk patients.

A Measured Path Forward

GLP-1s may end up helping people with pain and addiction — and if they do, that would be a genuine advance. But we should not rush from “promising” to “proven,” or expand GLP-1 use without a clear plan for monitoring and safety.

Panacea was a Greek myth about curing everything. The modern task — identifying who benefits, who is harmed, and how to use powerful medicines in ways that reduce suffering without creating new forms of it — is harder.

That will require larger, dedicated randomized trials in addiction, targeted studies in pain syndromes beyond knee osteoarthritis, longer-term musculoskeletal safety data, and honest communication about both the promise and the risks of GLP-1s.

Could a Popular Weight Loss Drug Reduce Pain?

By Madora Pennington

“When I look around at this room, I can't help but wonder. Is Ozempic right for me?” Jimmy Kimmel quipped to his audience of beautiful people when he hosted the Academy Awards last year.

It seems like everyone is taking Ozempic or drugs like it and losing weight. That class of drugs, known as GLP-1 medications for the hormones they enhance, slow digestion and promote feelings of satiety or fullness. As a result, people eat less and lose weight without the struggle of trying to stick to a diet. You feel fuller more quickly, eat less, and shed pounds.

GLP-1s are proving to have a lot more beneficial effects on the body than just weight loss. A recently published study found that low doses of semaglutide (the active ingredient in Ozempic and Wegovy) reduced alcohol cravings in people diagnosed with alcohol use disorder. When taking the weight-loss drugs, their alcohol intake was less.

In addition to food and alcohol, semaglutides also seem to reduce cravings for nicotine, cocaine, amphetamines and opioids, as well as problematic behaviors like gambling and compulsive shopping. Because the drugs reduce the reward chemical dopamine in the brain, those taking them are less motivated by their own brain signals to have another drink, put another item in their cart, have a hit of a drug, and so on.

Could GLP-1s also help pain patients?

The most obvious way a GLP-1 might reduce pain is through weight loss. Carrying excess weight causes additional wear-and-tear on the back and joints in the lower body. Every extra pound translates to four pounds of force on the knees, so even a modest amount of weight loss has the potential to reduce joint damage and pain.

Excess weight also limits range of motion, restricting joints and making it difficult for a person to exercise. Losing weight can lead to more physical activity, which can lessen pain and help keep the brain, joints and body healthy.

Another benefit of GLP-1 medications is that they lessen inflammation. In a recent study published in The New England Journal of Medicine, semaglutide provided substantial pain relief for patients with obesity and knee osteoarthritis. The exact mechanism of action is unclear, but researchers think its because the drug reduces inflammation and loss of cartilage in the knee joint.

“The findings confirm that substantial weight loss causes an often dramatic reduction in pain. If the effects shown in this trial are mediated by factors other than weight loss alone, new therapeutic avenues may be available,” David Felson, MD, a Professor of Rheumatology at Boston University School of Medicine, wrote in an editorial.

Other studies suggest that semaglutide could be a possible treatment for Alzheimer’s and Parkinson’s disease, as it lowers neuroinflammation, reduces plaque deposits in the brain, and helps generate new neurons. However, it’s only a supposition at this point that GLP-1s could mitigate the damage that chronic pain causes to the brain.

GLP-1s might help modulate pain in other ways. Both humans and animals turn to sweets and fat rich foods when in pain. Because GLP-1s regulate hunger and digestion, it’s possible they can improve pain. Tests on mice indicate that these drugs influence a certain nerve pain receptor. While definite answers and proof are a long way off, this discovery suggests new approaches to treating pain.

Before you run out to try them, be aware that Ozempic and other GLP-1 drugs carry risks. They often cause nausea and vomiting, and rare but serious problems such as pancreatitis, gastroparesis (paralysis of the stomach), and blindness.

They are also expensive. Insurance tends to limit semaglutide coverage to diabetics, so if you pay in cash without any discounts, 2 mg of Ozempic will cost about $1,050. Cheaper, generic semaglutides made overseas are available, as well as compounded versions made in-house by pharmacies. But those formulations have not been evaluated by the FDA and their quality is uncertain.
