Key Mechanism Factor 1
		Factor Name		Nephrotoxicity
		Factor Description		Drug-induced nephrotoxicity is a common and potentially serious complication of medication use. The kidneys are the primary organ for drug excretion, and when they are damaged can lead to decreased drug excretion.
Mechanism Description		Decreased renal excretion of Entecavir caused by Amphotericin B (cholesteryl sulfate) mediated nephrotoxicity

Recommended Action
Management		Caution is advised if entecavir is prescribed in combination with potentially nephrotoxic drugs (e.g., aminoglycosides polypeptide, glycopeptide, and polymyxin antibiotics amphotericin B adefovir cidofovir tenofovir foscarnet cisplatin deferasirox gallium nitrate lithium mesalamine certain immunosuppressants intravenous bisphosphonates intravenous pentamidine high intravenous dosages of methotrexate high dosages and/or chronic use of nonsteroidal anti-inflammatory agents).
