Vancomycin, Serum, Peak
Also known as: Vancocin®
Use
Use of intravenous vancomycin should be restricted to serious infections caused by susceptible staphylococci or other gram-positive bacteria when other antibiotics are ineffective or not tolerated.
Special Instructions
Not provided.
Limitations
Vancomycin is poorly absorbed from the gastrointestinal tract and does not penetrate the uninflamed meninges well. Dosage reductions are necessary for patients with renal insufficiency. The use of gel-barrier tubes is not recommended due to slow absorption of the drug by the gel. Hemolysis, lipemia, and gross bacterial contamination can cause rejection of specimens.
