Mechanism of Furosemide-Neomycin Interaction (Severity Level: Major)
Increased risk of nephrotoxicity Click to Show/Hide Mechanism Graph
Drug Name		Furosemide				Neomycin
Mechanism 1		Nephrotoxicity				Nephrotoxicity
Key Mechanism Factor 1
		Factor Name		Nephrotoxicity
		Factor Description		The combination of drugs that can induce nephrotoxicity may increase the risk of kidney injury. When kidney injury occurs, the inability to remove excess urine and waste from the body can lead to high levels of urea nitrogen, creatinine, and electrolytes (such as potassium and magnesium) in the blood.
Mechanism Description		Increased risk of nephrotoxicity by the combination of Furosemide and Neomycin
Increased risk of ototoxicity Click to Show/Hide Mechanism Graph
Drug Name		Furosemide				Neomycin
Mechanism 2		Ototoxicity				Ototoxicity
Key Mechanism Factor 2
		Factor Name		Ototoxicity
		Factor Description		Ototoxicity is the damage to the organs of hearing and/or balance following exposure to drugs or chemicals that affect the inner ear. Ototoxic drugs can impair hearing, balance, or both.
Mechanism Description		Increased risk of ototoxicity by the combination of Furosemide and Neomycin

Recommended Action
Management		The use of aminoglycoside antibiotics in combination with loop diuretics or intravenous mannitol should generally be avoided. Renal function tests and serial, vestibular, and audiometric tests should be performed as appropriate for the type of diuretic before and during therapy if coadministration is necessary.
