Vancomycin is an antibiotic drug used to treat serious, life-threatening infections by gram-positive bacteria that are resistant to less-toxic agents. The reference range for vancomycin trough levels is 5-15 mcg/mL. The reference range for vancomycin peak levels is 20-40 mcg/mL.
Do you give vancomycin if trough is low?
The 2020 vancomycin therapeutic guidelines recommends a move away from monitoring vancomycin trough levels to targeting an AUC24:MIC (24-hour area under the curve (AUC) to minimum inhibitory concentration ratio). Dosing vancomycin using trough-only monitoring is no longer recommended.
When should trough levels be drawn for vancomycin?
Trough: just before 4th dose of a new regimen (prior to 3rd dose for dosing intervals ≥ 24 hours or changing renal function) – Trough levels should be obtained within 30 minutes before the next scheduled dose. – Weekly vancomycin levels should be obtained for long-term vancomycin use with stable renal function.
What level of vancomycin is toxic?
It has been described that vancomycin trough plasma levels >20 μg/mL or AUC0–24 h >700 μg/mL*h are related to nephrotoxicity.
What is trough and peak level?
The trough level is the lowest concentration in the patient’s bloodstream, therefore, the specimen should be collected just prior to administration of the drug. The peak level is the highest concentration of a drug in the patient’s bloodstream.
What color tube is a Vanco trough?
Red-top tube, lavender-top (K2- or K3- EDTA) tube, or green-top (heparin) tube. Do not use a gel-barrier tube. The use of gel-barrier tubes is not recommended due to slow absorption of the drug by the gel.
When should peak levels be drawn?
A trough level is drawn immediately before the next dose of the drug is administered. A peak level is drawn 1 to several hours after the drug is administered (depending on the drug).
When should peak and trough levels be drawn?
When should trough levels be taken?
What is peak level in phlebotomy?
The peak for a drug is when the level of the drug in the patient’s body is the highest. To assess drug concentrations during the trough phase, blood should be drawn immediately before the next dose.

What is the therapeutic range for vancomycin?
ers concluded that vancomycin dosages of 500 mg every 6. hours or 1 g every 12 hours provide AUC/MIC values of f. 100–250 and suggested that values around 500 may enhance. the therapeutic effectiveness of vancomycin in humans.
What is the maximum dose of vancomycin?
The usual dose is 40 milligrams per kilogram of body weight per day, divided into three or four doses and taken for seven to 10 days. The total daily dose usually does not exceed 2000 milligrams. Intravenous (IV) treatment with vancomycin is highly variable.
When to check Vanco trough?
Typically, the medication reaches peak concentration between one and two hours after administration. Depending on the size of the dose, the patient’s general health, and other factors, the timing of the trough may vary. A doctor can request a peak reading after administration and check back to see when the patient hits the trough.
When to check Vanco level?
Peak levels are collected 1 to 2 hours after the completion of the intravenous vancomycin dose. The trough and sometimes peak values are used by clinical pharmacists and healthcare practitioners to calculate rates of absorption and clearance of the drug.
