Resumo

Concurrent use of cefalexin with an aminoglycoside such as kanamycin has been associated with an increased risk of kidney injury in some reports. Aminoglycosides themselves are nephrotoxic and ototoxic, so any added renal impairment can raise drug exposure and toxicity.

O que esta interação significa em palavras simples

Cefalexin and Kanamycin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Nível de evidência: Low

Por que acontece

Additive nephrotoxic potential, with reduced renal function leading to higher aminoglycoside accumulation and ototoxicity risk.

O que fazer

Monitor serum creatinine and urine output, and measure aminoglycoside levels where applicable. Adjust the kanamycin dose to renal function and report hearing or balance changes promptly.
