Two common over-the-counter medications may elevate urinary phenol to levels exceeding 75 mg/liter (ppm). This study presents data indicating that it is invalid to correct urinary phenol levels to specific gravity of 1.024. Animal studies indicate that having elevated urinary phenol levels secondary to phenyl salicylate ingestion are not harmful.
