Renal Impairment
- IV (Adults): An initial loading dose of 750 mg–1 g (not less than 15 mg/kg); serum level monitoring is optimal for choosing maintenance dose in patients with renal impairment; these guidelines may be helpful. CCr 50–80 mL/min: 1 g every 1–3 days; CCr 10–50 mL/min: 1 g every 3–7 days; CCr <10 mL/min: 1 g every 7–14 days.
Endocarditis Prophylaxis in Penicillin-Allergic Patients
- IV (Adults and Adolescents): 1 g single dose 1 hr preprocedure.
- IV (Children): 20 mg/kg single dose 1 hr preprocedure.
Diarrhea Due to C. difficile
- PO (Adults): 125 mg every 6 hr for 10 days.
- PO (Children): 40 mg/kg/day divided into 3 or 4 doses for 7–10 days (not to exceed 2 g/day).
Staphylococcal Enterocolitis
- PO (Adults): 500–2000 mg/day in 3–4 divided doses for 7–10 days.
- PO (Children): 40 mg/kg/day in 3–4 divided doses for 7–10 days (not to exceed 2 g/day).
Therapeutic Classification: anti-infectives
Absorption: Poorly absorbed from the GI tract.
Distribution: Widely distributed to tissues. Some penetration (20–30%) of CSF.
Metabolism/Excretion: Oral doses excreted primarily in the feces; IV vancomycin eliminated almost entirely by the kidneys.
Half-life: Neonates: 6–10 hr; Children 3 mo–3 yr: 4 hr; Children >3 yr: 2–2.3 hr; Adults: 5–8 hr (↑ in renal impairment).
