Vancomycin dosage varies depending on the patient's age, weight, kidney function, and the severity of the infection being treated [1]. For adults with normal kidney function, a typical intravenous dose is 1 gram every 12 hours, or 500 mg every 6 hours [1]. For severe infections, the dose may be increased to 1.5 grams every 12 hours, or 750 mg every 8 hours [1].
What are the recommended vancomycin doses for children?
Pediatric dosing for vancomycin is also weight-based. For children over 1 month old, the recommended intravenous dose is typically 10 mg per kilogram of body weight every 6 hours, or 15 mg per kilogram every 8 hours [1]. For neonates, doses are usually lower and more frequent, often starting at 15 mg per kilogram every 48 hours for the first week of life, then adjusting based on weight and age [1].
How is vancomycin dosing adjusted for kidney problems?
Patients with impaired kidney function require reduced vancomycin doses to prevent accumulation and toxicity [1]. Dosing adjustments are based on the estimated glomerular filtration rate (eGFR) or measured creatinine clearance [1]. For example, if a patient's kidney function is significantly reduced, the dose might be given less frequently, such as every 24 to 96 hours, or the dose size may be decreased [1].
What is the target blood level for vancomycin?
Therapeutic drug monitoring of vancomycin blood levels is crucial to ensure effectiveness and minimize toxicity [2]. The target trough concentration, measured just before the next dose, is generally between 10 and 20 mcg/mL for most infections [2]. For serious or methicillin-resistant Staphylococcus aureus (MRSA) infections, a higher trough level of 15 to 20 mcg/mL may be targeted [2].
Are there different forms of vancomycin available?
Vancomycin is primarily administered intravenously for systemic infections [1]. It is also available in oral form, which is used to treat Clostridioides difficile colitis in the intestines, as it is not absorbed into the bloodstream from the gut [1][3].
