A recent study sheds light on an unexpected benefit of GLP-1 agonist medications, commonly used for managing diabetes and weight loss. These drugs, such as Ozempic, may also reduce the risk of opioid overdose and alcohol intoxication in individuals with substance use disorders.
The research, published in Addiction, examined health data from 1.3 million people over a span of nearly nine years, gathered from 136 U.S. hospitals. Among those analyzed were 500,000 individuals with opioid use disorder and more than 800,000 with alcohol use disorder. The study found that people using GLP-1 drugs experienced significant reductions in risk—40% lower for opioid overdose and 50% lower for alcohol intoxication—compared to those who weren’t on these medications.
“It helps to underline another significant benefit of this class of medication,” said Dr. Angela Fitch, co-founder and chief medical officer at knownwell, a healthcare provider that promotes weight-inclusive care. Her comments emphasize the potential these drugs hold for addressing addiction, in addition to their established roles in diabetes and weight management.
The appeal of these medications, according to experts, stems from the fact that they offer a less stigmatized alternative for treating addiction. “The existing medications for treating substance use disorder are underutilized and stigmatized,” said Fares Qeadan, an associate professor of biostatistics at Loyola University in Chicago. He noted that medications like Ozempic, originally intended for diabetes and weight loss, offer a way to tackle addiction without the negative associations often attached to traditional treatments.
GLP-1 drugs work by mimicking a hormone in the body that helps regulate blood sugar and insulin. These medications also slow digestion and curb appetite, which aids in weight loss and managing diabetes. While the exact mechanism isn’t fully understood, some studies suggest that GLP-1 drugs may influence brain pathways involved in the reward system, possibly reducing cravings for substances like alcohol and opioids.
A previous study reinforced this theory, showing that adding the GLP-1 agonist exenatide helped people with obesity and alcohol use disorder reduce their drinking. However, the recent findings from Addiction don’t definitively prove a direct cause-and-effect relationship between GLP-1 drugs and reduced overdose or intoxication risk. The research focused solely on hospitalizations, so it remains unclear how the drugs might perform in less severe cases.
At present, GLP-1 drugs are not approved by the U.S. Food and Drug Administration (FDA) for treating addiction. Dr. Fitch highlighted this limitation, saying, “One of the challenges that we have as clinicians is we know that some of these benefits help patients. And not being able to get them access is very challenging.”
Substance use disorder, defined by the inability to stop using drugs or alcohol despite its harmful effects, continues to be a major public health issue. According to the Centers for Disease Control and Prevention (CDC), excessive alcohol use contributes to 178,000 deaths annually, while over 75% of drug overdose deaths in 2022 involved opioids.
