Butorphanol Nasal Spray
How does this medication work? What will it do for me?
Butorphanol belongs to the family of medications known as narcotic analgesics (pain-relievers). It is used for the relief of moderate-to-severe acute pain. It works by affecting the pain centers of the central nervous system (the nerves that carry pain signals back and forth to the brain). Butorphanol nasal spray works within 15 to 30 minutes to relieve pain.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each mL of clear, colourless aqueous solution contains 10 mg of butorphanol tartrate. Nonmedicinal ingredients: 0.2 mg/mL benzethonium chloride as a preservative, citric acid, purified water with hydrochloric acid and sodium hydroxide.
How should I use this medication?
The dose depends on your response to the medication. The usual recommended adult dose for starting nasal therapy is one spray in one nostril (1 mg). A repeat dose may be allowed if there is inadequate pain relief within 60 to 90 minutes of the initial dose.
This dosing sequence can be repeated every 3 to 4 hours as needed for pain relief. The dose may be increased as directed by your doctor, but doses of more than 16 mg daily are not normally recommended. The effectiveness of butorphanol for periods longer than 3 days has not been established.
For people who experience more severe pain, their doctor may prescribe an initial dose of one spray in each nostril. If this is the case, ensure there is a place for you to lie down, as drowsiness or dizziness may occur. The next dose should not be used for 3 or 4 hours. Seniors and those with kidney or liver damage may require different dosing as prescribed by their doctor.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
This medication may be habit-forming if taken for long periods of time. Do not stop taking this medication without talking with your doctor. If this medication is stopped suddenly, you may experience withdrawal symptoms such as anxiety, sweating, trouble sleeping, shakiness, nausea, tremors, diarrhea, or hallucinations. If you plan on stopping the medication, your doctor may want you to reduce the dose gradually to reduce the severity of withdrawal effects.
It is important to use this medication exactly as prescribed by your doctor. Do not take more of this medication than your doctor has recommended. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abdominal (stomach) conditions: Butorphanol, like other narcotic medications, can cause constipation. It may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have stomach problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Accidental Use: When butorphanol nasal spray is used by anyone other than the person for whom it was prescribed, it can have dangerous and even fatal side effects. Keep this medication out of sight and reach of children.
Alcohol use: Alcohol increases the risk of severe side effects from butorphanol, such as decreased blood pressure, seizures, breathing problems, severe drowsiness, and potentially death. Consuming alcohol while you are taking butorphanol is not recommended.
Breathing: Butorphanol can suppress breathing. If you are at risk for breathing difficulties, such as asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dependence and withdrawal: Physical dependence, psychological dependence, and abuse have occurred with the use of butorphanol. People with a history of past or current substance use problems may be at greater risk of developing abuse or addiction while taking this medication.
Abuse is not a problem with people who require this medication for pain relief. If you suddenly stop taking this medication, you may experience withdrawal symptoms such as anxiety, agitation, diarrhea, and hallucinations. If you have been taking this medication for a while, it should be stopped gradually as directed by your doctor.
Dizziness: Butorphanol can cause severe dizziness, especially when rising from a sitting or lying position. This is more likely to occur within the first hour of butorphanol being used or when other medications with similar side effects are being taken. People taking medications that can cause dizziness should rise slowly from sitting or lying down to reduce the possibility of severe dizziness or fainting.
Drowsiness/reduced alertness: This medication may cause drowsiness or dizziness. Do not drive, operate machinery, or perform other potentially hazardous tasks until you have determined how this medication affects you.
Head injury: If you have had a head injury or have increased pressure in the head, you may have a higher risk of experiencing side effects (breathing problems) or worsening of your condition while taking this medication. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Decreased kidney function can cause a buildup of butorphanol in the body, resulting in more severe side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Decreased liver function can cause a buildup of butorphanol in the body, resulting in more severe side effects. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood pressure: Butorphanol can cause low blood pressure or make low blood pressure worse. If you experience severe dizziness, especially when standing from a lying or sitting position, contact your doctor.
Serotonin Syndrome: Severe reactions are possible when butorphanol is combined with medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors, medications used to treat depression. These combinations can cause an increase in the amount of serotonin in the body. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, changes in mental state including delirium and agitation. Coma and death are possible.
If you are taking antidepressants, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately. Withdrawal symptoms have been noted in newborns of mothers who used butorphanol during pregnancy.
Breast-feeding: This medication may pass into breast milk. If you are a breast-feeding mother and are using butorphanol, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of this medication have not been established for children and adolescents under 18 years of age.
Seniors: Seniors may be more sensitive to the side effects of butorphanol, particularly dizziness.
