Side effects due to ingestion of nalidixic acid in a 46 year old patient with phenacetine-induced interstitial nephritis and severe renal failure are reported. This observation underlines the point that, besides the direct neurotoxic effect of nalidixic acid, disturbance of the acid-basic equilibrium could be seen in patients with renal failure in particular. A hypothetical pharmacokinetic model suggests that two metabolites of nalidixic acid could provide enough hydrogen ion to induce acidosis in cases of renal failure.
