US Brand Name
Butorphanol injection is used to relieve pain. It may also be given before a surgery, when giving birth, or with general anesthesia before an operation. It belongs to the group of medicines called narcotic analgesics (pain medicines). Butorphanol acts on the central nervous system (CNS) to relieve pain.
When butorphanol injection is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
This medicine is to be given only by or under the direct supervision of your doctor.
