Relationship of continuous infusion lorazepam to serum propylene glycol concentration in critically ill adults. Each milliliter of Ativan injection (2 mg of lorazepam per milliliter, Wyeth–Ayerst Laboratories) contains 0.8 ml of propylene glycol. There have been reports of possible propylene glycol toxicity (e.g., lactic acidosis, hyperosmolality, hypotension) and possible polyethylene glycol toxicity (e.g., acute tubular necrosis) during administration of Lorazepam Injection at higher than recommended doses. This implies that a dose of 5 mg/kg/day of IV diazepam would have the same potential for toxicity as 1 mg/kg/day of lorazepam. 2008. 2005 Nov;6(7):745-8. doi: 10.2174/138945005774574416.
