Interactions

with other drugs

  • Synergistic with beta-lactam antibacterials agents.
  • May precipitate when in contact with other pharmaceutical agents if given through and IV infusion set.
  • Care when used in conjunction with phenylbutazone since some studies have indicated that phenylbutazone can change some of the kinetic parameters of gentamicin, eg a reduction in the half-life.
  • Diuretics can increase risk of ototoxicity.
  • Gentamicin can potentiate neuromuscular blockade with non-depolarizing muscle relaxants.
  • Increased risk of nephrotoxicity with amphotericin B and cisplatin.
