Short answer
Yes, they're often prescribed together, but the combination increases the risk of low blood sugar. Your insulin or sulfonylurea dose may need to be lowered.
Why it happens
GLP-1 medicines like semaglutide lower blood sugar. Insulin and sulfonylureas (like glipizide) do too, so together blood sugar can drop too far.
What to do
- Check your blood sugar more often when starting or increasing a GLP-1.
- Ask your prescriber whether your insulin or sulfonylurea dose should change.
- Keep a fast-acting sugar source with you.
Signs to watch for
- Shakiness, sweating or a pounding heart
- Confusion or sudden hunger
- Dizziness
If symptoms are severe, call 911 or go to the nearest emergency room.
