With other drugs

Antibiotics

Combination with Chloramphenicol, macrolide antibiotics or tetracyclines may produce antagonistic effects.

Adsorbents and antacids containing cations (Mg, Al)

Sucralfate and zinc salts

  • May inhibit absorption; separate doses of these drugs.
Theophylline
  • Increases plasma theophylline levels (in humans) - monitor carefully.
NSAIDs (non-steroidal Anti-inflammatory drugs Anti-inflammatory drugs
  • Potential pharmacodynamic interactions in the CNS could lead to seizures (in susceptible animals).
Probenecid
  • Blocks the tubular secretion of fluoroquinolones and may increase circulating concentrations and half-life.
