A GLP-1 receptor agonist was started in a patient who reports gastrointestinal issues. What is the best way to manage these common side effects?

• A. switch to glimepiride
• B. titrate GLP-1 RA dose slowly
• C. switch to semaglutide PO
• D. change to shorter acting GLP-1 RA

Answer: (B)

GI side effects from GLP-1 receptor agonists come from their tendency to slow gastric emptying and affect appetite. These effects are highly dose-dependent and most pronounced when the dose is started high or increased quickly. The best way to manage this common issue is to start with a very low dose and titrate upward gradually over several weeks. This slow ramp allows the gut to adapt, reducing nausea, vomiting, and diarrhea while still delivering the drug’s benefits. In practice, use a stepwise titration schedule—begin at the minimum dose and increase at intervals (often weekly or biweekly) to the target dose as tolerated. If symptoms persist despite optimal titration, consider alternatives rather than pushing a higher dose, since dose-related GI intolerance is the primary issue in this scenario.
