Patients who receive Ativan Injection as a premedicant should be cautioned that driving a motor vehicle, operating machinery, or engaging in hazardous or other activities requiring attention and coordination, should be delayed for 24 to 48 hours following the injection or until the effects of the drug, such as drowsiness, have subsided, whichever is longer. Sedatives, tranquilizers and narcotic analgesics may produce a more prolonged and profound effect when administered along with injectable Ativan. This effect may take the form of excessive sleepiness or drowsiness and, on rare occasions, interfere with recall and recognition of events of the day of surgery and the day after.
50 mg/m2 IV 30 to 60 minutes prior to induction of anesthesia, with repeat doses of 50 mg/m2/dose IV every 6 hours or as a continuous infusion until the patient has recovered, has been recommended. For patients with congenital adrenal hyperplasia (CAH), 2 mg/kg/dose IV at induction of anesthesia with repeat doses every 4 hours or as a continuous IV infusion for prolonged procedures or recovery times has also been recommended. Alternatively, an initial stress dose of 25 mg IM followed by IV doses equivalent to 3 to 4 times the daily maintenance dose divided every 6 hours has been recommended.
