    OTHER INFORMATION

    IV postoperative use: Give 1.5–3 micrograms/kg; if response inadequate, increments of 100 micrograms every 2 minutes. Further dose by IM injection if neededOR dilute 400 micrograms in 100 mL sodium chloride 0.9% or glucose 5% (4 micrograms/mL) and give by continuous infusion. Titrate dose according to responseOpioid overdosage: initial dose of 400– 2000 micrograms IV; may be repeated at 2–3 minute intervals if the desired degree of counteraction and improvement in respiratory function is not obtained. (If no response after 10 mg then question the diagnosis of opioid induced toxicity.) OR give as an infusion: 4 mg in 20 mL (200 mcg/mL solution)
