What is the most important information I should know about butorphanol (Stadol)?
You should not use butorphanol if you have recently used narcotic medications and have become dependent on them.
Butorphanol may be habit-forming and should be used only by the person it was prescribed for. Butorphanol should never be given to another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
Do not drink alcohol while you are using butorphanol. Dangerous side effects or death can occur when alcohol is combined with a narcotic pain medicine. Check your food and medicine labels to be sure these products do not contain alcohol.
Butorphanol can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Never use more than your prescribed dose of butorphanol. Tell your doctor if the medicine seems to stop working as well in relieving your pain. Do not stop using butorphanol suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.
