Abstract

Hydroxocobalamin causes reddish discoloration of the urine, mimicking hematuria. Clinicians should be aware of this common side effect of the rarely used drug to prevent unnecessary consultations and work-up. Additional benign causes of red urine include foods such as beets, rhubarb, and medications such as rifampin, phenazopyridine.
