No Direct Interaction

Most common antibiotics do not interact with semaglutide (Ozempic, Wegovy). These include:

  • Amoxicillin
  • Azithromycin (Z-Pak)
  • Cephalexin (Keflex)
  • Doxycycline
  • Augmentin

Ozempic works by mimicking GLP-1 hormone. Antibiotics work by killing bacteria. They do not affect each other directly.
