Butorphanol is a narcotic analgesic (pain medicine) that is sprayed into the nose. It is used to relieve moderate or severe pain. It is also used to relieve pain that occurs after an operation.
Narcotic analgesics act in the central nervous system (CNS) to relieve pain. Some of their side effects are also caused by actions in the CNS.
If a narcotic is used for a long time, it may become habit-forming (causing mental or physical dependence). Physical dependence may lead to withdrawal side effects when you stop taking the medicine.
butorphanol is available only with your doctor's or dentist's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For butorphanol, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to butorphanol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Studies on butorphanol have been done only in adult patients, and there is no specific information comparing use of butorphanol in children with use in other age groups.
Elderly people are especially sensitive to the effects of butorphanol. This may increase the chance of side effects, especially dizziness, during treatment. Studies in older adults show that butorphanol stays in the body for a longer time than it does in younger adults. Your doctor will consider this when deciding on your dose.

Using butorphanol with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of butorphanol. Make sure you tell your doctor if you have any other medical problems, especially:
You will be given an instruction sheet with your prescription for butorphanol that explains how to use the pump spray unit. If you have any questions about using the unit, ask your health care professional.
The dose of butorphanol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of butorphanol. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of butorphanol, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Butorphanol will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; other prescription pain medicines, including other narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Do not drink alcoholic beverages, and check with your medical doctor or dentist before taking any of the medicines listed above, while you are using butorphanol.
butorphanol may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to butorphanol before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert and clearheaded.
Dizziness, lightheadedness, or fainting may occur, especially in the first hour after use or when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem.
Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using butorphanol.
Butorphanol may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
If you have been using butorphanol regularly for several weeks or more, do not suddenly stop using it without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are using before stopping completely, in order to lessen the chance of withdrawal side effects.
If you think you or someone else may have used an overdose, get emergency help at once. Using an overdose of butorphanol or taking alcohol or CNS depressants with butorphanol may lead to unconsciousness or death. Signs of overdose include convulsions (seizures), confusion, severe nervousness or restlessness, severe dizziness, severe drowsiness, slow or troubled breathing, and severe weakness.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Get emergency help immediately if any of the following symptoms of overdose occur:
