About GLP-1 Drug Interactions

Major Interactions

Can cause serious harm. Do not combine without explicit doctor approval and monitoring.

Moderate Interactions

May require dose adjustment or monitoring. Consult your healthcare provider.

Minor Interactions

Generally safe but may cause mild side effects. Monitor as directed.

How GLP-1 Medications Interact with Other Drugs

GLP-1 medications (Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda) work by slowing gastric emptying, reducing appetite, and improving blood sugar control. These mechanisms can affect how your body processes other medications.

Most Common Interaction Categories:

  • Diabetes medications: Insulin and sulfonylureas can cause hypoglycemia when combined with GLP-1s
  • Blood thinners: Warfarin and DOACs may need monitoring due to absorption changes
  • Oral contraceptives: May be less effective due to delayed gastric emptying
  • Thyroid medications: Levothyroxine absorption may be affected
  • Blood pressure medications: May need dose adjustment as weight loss occurs
