Warning: Nephrotoxicity, Ototoxicity, Neuromuscular Blockade and Fetal HarmNephrotoxicity has been reported with plazomicin. The risk of nephrotoxicity is greater in patients with impaired renal function, the elderly, and in those receiving concomitant nephrotoxic medications. Assess creatinine clearance in all patients prior to initiating therapy and daily during therapy. Therapeutic drug monitoring (TDM) is recommended for complicated urinary tract infection (cUTI) patients with CrCl less than 90 mL/min to avoid potentially toxic levels.Ototoxicity, manifested as hearing loss, tinnitus, and/or vertigo, has been reported with plazomicin. Symptoms of aminoglycoside-associated ototoxicity may be irreversible and may not become evident until after completion of therapy. Aminoglycoside-associated ototoxicity has been observed primarily in patients with a family history of hearing loss, patients with renal impairment, and in patients receiving higher doses and/or longer durations of therapy than recommended.Aminoglycosides have been associated with neuromuscular blockade. During therapy with plazomicin, monitor for adverse reactions associated with neuromuscular blockade, particularly in high-risk patients, such as patients with underlying neuromuscular disorders (including myasthenia gravis) or in patients concomitantly receiving neuromuscular blocking agents.Aminoglycosides, including plazomicin, can cause fetal harm when administered to a pregnant woman .
