Practice › Interactions metformin delayed gastric emptying needs a source

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

post #150 is right about the mechanism and I think understates the practical bit.

Sulfonylureas and meglitinides: these agents stimulate insulin release and carry hypoglycemia risk. Combining them with semaglutide or tirzepatide requires dose adjustment of the secretagogue and close monitoring. The combination is not contraindicated but requires active management.

Oral medications versus time: if you take an oral medication 30 minutes before semaglutide (which slows gastric emptying), the delayed stomach emptying affects when and where the oral medication is absorbed. Separating by a larger interval (1 to 2 hours) usually resolves this.

Insulin interaction: semaglutide and tirzepatide are not contraindicated with insulin but the combination carries hypoglycemia risk if insulin doses are not adjusted. That is a reason for close monitoring, not for avoiding the combination.
