Antibiotics in renal impairment – RGH Pharmacy E-Bulletin


Confusion surrounds the prescribing of antimicrobials in renal impairment; whether to reduce the dose or extend the dosing interval. Suggested dose adjustments in renal impairment for many commonly used antibiotics are provided here, based on tables which can be found in the Therapeutic Guidelines (TG) Antibiotic, 14th edition.

No dose adjustment is required for some agents – these include azithromycin, roxithromycin, ceftriaxone, cefaclor, clindamycin, doxycycline, linezolid, moxifloxacin, phenoxymethylpenicillin, metronidazole among others.
