Also known as: Vancocin®
Use
Monitor therapeutic drug level
Special Instructions
Not provided.
Limitations
The use of gel-barrier tubes is not recommended due to the slow absorption of vancomycin by the gel, which could lead to decreased drug levels that may be clinically significant. High trough concentrations greater than 20 µg/mL are associated with nephrotoxicity.
