GLP-1 medications have become increasingly common as treatments for Type 2 diabetes and weight management. Medications such as semaglutide and tirzepatide are now used by millions of people across the country. As their popularity grows, defense attorneys and medical experts are paying closer attention to how these medications may intersect with DUI investigations and defense strategies.
It is important to understand that taking a GLP-1 medication does not provide an automatic defense to a DUI charge. However, a medication’s effects on the body may raise questions that are relevant in certain cases.
GLP-1 medications may affect the integrity of BAC testing
One of the primary ways GLP-1 medications work is by slowing gastric emptying. This means food and liquids remain in the stomach longer than they otherwise would. Some users also experience side effects such as nausea, vomiting, acid reflux and regurgitation. These symptoms can become important when a DUI case relies heavily on breath-test evidence.
Breath-testing devices are designed to measure alcohol from deep lung air. However, alcohol that reaches the mouth through reflux or regurgitation may potentially affect test results. In some cases, a defense attorney may investigate whether a driver’s medical condition, medication use or gastrointestinal symptoms could have influenced the reliability of a breath test.
GLP-1 medications may also cause side effects that could be misinterpreted by law enforcement. Fatigue, dizziness, nausea, difficulty concentrating and other symptoms sometimes associated with these medications may resemble signs that officers commonly associate with impairment. This does not mean officers acted improperly, but it may create issues worth exploring during the defense of a case.
As research regarding GLP-1 medications continues to evolve, their potential role in DUI cases may receive increasing attention and benefit from increasing relevance. Anyone facing DUI charges while taking these medications should inform their legal team as early as possible as a result.
