Levorphanol, brand name Levo-Dromoran, is an opioid medication used to treat moderate to severe pain. Levorphanol is indicated for the management of moderate to severe pain where an opioid analgesic
is appropriate. It is a potent synthetic opioid mu-receptor agonist similar in action to morphine. Like other opioid
mu-receptor agonists, it is believed to act at receptors in both the brain and spinal cord to alter the transmission
and perception of pain. The onset and peak analgesic effects following administration of levorphanol are similar to
morphine when administered at equal analgesic doses. Levorphanol produces a degree of respiratory depression
similar to that produced by morphine at equal analgesic doses, and like many opioid mu-receptor agonists,
levorphanol produces euphoria or has a positive effect on mood in many individuals.

Usual Adult Dose for Light Sedation
Premedication for Anesthesia:
1 to 2 mg IM or subcutaneously, administered 60 to 90 minutes before surgery. Older or debilitated patients usually require less drug. Two mg of levorphanol is approximately equivalent to 10 to 15 mg of morphine or 100 mg of meperidine.
Usual Adult Dose for Pain
IV: 1 mg every 3 to 6 hours as needed.
IM or subcutaneous: 1 to 2 mg every 6 to 8 hours as needed.
Oral: 2 mg every 6 to 8 hours as needed.
May be increased to 3 mg every 6 to 8 hours.
