What should I know about Bacteriostatic Water before using it?

The benzyl alcohol, which is the preservative in Bacteriostatic Water, has been found to be toxic in newborns. Prior to administration of the diluted or dissolved drug, look for clarity, discoloration or any unexpected precipitation in the vial. This is considered a Category C drug, so it is not known if it can harm a fetus or affect a woman's reproductive capacity. Make certain the drug is mixed thoroughly and completely before administering. Also, do not use this intravenously unless the osmolar concentration of ingredients results in an isotonic mixture. That is, it has the same salt concentration as the body and cells.
