Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances, both toxic chemicals and medications, on kidney function. There are various forms, and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity.

Nephrotoxicity should not be confused with some medications predominantly excreted by the kidneys needing their dose adjusted for the decreased kidney function (e.g., heparin, lithium).

Types of toxicity


Direct tubular effect

Acute interstitial nephritis

Main article : Acute interstitial nephritis

Chronic interstitial nephritis

Acute glomerulonephritis

Drug-induced glomerular disease is not common but there are a few drugs that have been implicated. Glomerular lesions occur primarily through immune-mediated pathways rather than through direct drug toxicity.

Causes of diabetes insipidus

Other nephrotoxins


Nephrotoxicity is usually monitored through a simple blood test. A decreased creatinine clearance indicates poor kidney function. In interventional radiology, a patient's creatinine clearance levels are all checked prior to a procedure.[citation needed]

Serum creatinine is another measure of kidney function, which may be more useful clinically when dealing with patients with early kidney disease. Normal creatinine level is between 80 - 120 μmol/L.[citation needed]


The word nephrotoxicity (/ˌnɛfroʊtɒkˈsɪsɪti/) uses combining forms of nephro- + tox- + -icity, yielding "kidney poisoning".[citation needed]
