This document provides dosing guidelines for various antibiotics in patients with renal impairment. It lists the usual adult dose, and recommended adjustments based on creatinine clearance ranges for HD, CAPD, and different levels of renal failure estimated by CrCl. For most antibiotics, the usual dose is reduced and dosing interval increased as renal function declines. HD and CAPD patients may require additional supplemental doses or dose adjustments.
