GLP-1 medicines alongside a second GLP-1 medicine: the verdict
Avoid together
The labels for Wegovy and Zepbound say not to take either medicine alongside another GLP-1 medicine or a different product with the same ingredient.
What the label says about interactions
Every interaction that the Ozempic label lists. Any question about a second GLP-1 medicine falls under one of these.
| Named in the label | The risk | What the label tells doctors |
|---|---|---|
| Insulin or sulfonylureas | Low blood sugar | Using it with insulin or a sulfonylurea, such as glipizide or glimepiride, makes low blood sugar more likely; your doctor may lower those doses. |
| Oral medicines | Pills absorbed differently | It slows the emptying of your stomach, and that can change how other pills are absorbed. |
