“…Consistent compatibility has been demonstrated with solutions of vancomycin, at concentrations ranging from 0.1 to 10 mg/ mL, and heparin sodium 100-5000 units/mL for ALT. 33,[35][36][37]47,[52][53][54][55] There are anecdotal reports of visual haze with the use of higher concentrations of vancomycin (≥5 mg/mL) and heparin sodium (≥5000 units/ mL) in solution, but agitation appears to alleviate this concern; the clinical significance of these findings is unknown, and the phenomenon may be manufacturer specific. Vancomycin and heparin sodium at lower concentrations (0.025-0.5 mg/mL and 10-100 units/mL, respectively) have been evaluated, with no reported incompatibilities, but this research entailed less wellvalidated methodologies.…”
