Amoxicillin Crystalluria: A Rare Side-Effect of a Commonly Prescribed Antibiotic

Abstract

Although crystalluria is a frequent finding in the routine examination of urine, amoxicillin crystalluria is a rare event whose incidence remains unknown. Crystalluria caused by amoxicillin is very uncommon and may be asymptomatic or have severe renal implications. The authors describe the case of an 87-year-old female patient who presented with massive amoxicillin crystalluria due to poor hydration, low urinary pH and high intravenous amoxicillin dosage.
