Butorphanol (Nasal route)



Brand Names:

  • Stadol NS

Dosage Forms:

  • Spray





Opioid Agonist/Antagonist



Uses of This Medicine:

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.

This medicine is available only with your doctor's or dentist's prescription.

Before Using This Medicine:

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 this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Studies on this medicine 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.

Proper Use of This Medicine:

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.

To use:

  • Use this medicine only as directed by your medical doctor or dentist. Do not use more of it, do not use it more often, and do not use it for a longer time than your medical doctor or dentist told you. This is especially important for elderly patients, who may be more sensitive to the effects of butorphanol. If too much is used, the medicine may become habit-forming (causing mental or physical dependence) or lead to medical problems because of an overdose.
  • Remove the protective cover and clip. Before you use each new bottle of butorphanol, the spray pump needs to be started. To do this, point the sprayer away from you and other people or pets. Pump the spray unit firmly about 7 or 8 times. A fine, wide spray should come out by the seventh or eighth time you pump the unit. If the unit is not used for 48 hours or longer, the spray pump should be started again by pumping it 1 or 2 times only.
  • Before each use, blow your nose gently.
  • For a 1-mg dose, insert the spray tip into one nostril. Close off the other nostril by pressing the side of your nose with your index finger. Tilt your head slightly forward and spray one time. Sniff gently with your mouth closed.
  • Remove the spray tip from your nostril. Tilt your head back and sniff gently.
  • For a 2-mg dose, repeat these steps using the other nostril.
  • Replace the protective cover and clip after each use.


The dose of this medicine 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 this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

  • For nasal dosage form:

This dosing procedure may be repeated in three to four hours as needed. However, if pain is severe, a 2-mg dose (one spray in each nostril) may be used every three to four hours, but it is important to remain lying down if drowsiness or dizziness occurs.
      • Children and teenagers Use and dose must be determined by your doctor.

Precautions While Using This Medicine:

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 this medicine.

This medicine 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 this medicine 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 this medicine.

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 this medicine 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 this medicine or taking alcohol or CNS depressants with this medicine 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.
