Common questions about butorphanol
Below you’ll find answers to a few commonly asked questions about butorphanol.
Can butorphanol be prescribed for dogs?
Yes, veterinarians may recommend butorphanol for dogs and other animals for pain relief and other uses. That said, you should never administer this medication or any others to a pet without your veterinarian’s recommendation. Doing so could be harmful.
For more information about butorphanol for dogs, talk with your vet.
Is butorphanol a controlled substance?
Yes, butorphanol is a controlled substance. This means it carries the risks of misuse and addiction. Misuse refers to using a drug in a way other than how a doctor prescribes it. Addiction refers to feeling unable to stop using a drug, even though it may be causing harm.
In fact, butorphanol has a boxed warning about the risks of misuse and addiction. Boxed warnings are serious warnings from the Food and Drug Administration (FDA). To learn more, see the “Interactions and warnings for butorphanol” section below.
If you have concerns about treatment with a controlled substance, or misuse or addiction with butorphanol, talk with your doctor or pharmacist.
Does butorphanol have a reversal process?
Yes, similar to other opioids, the effects of butorphanol can be reversed. This can be done with a drug called an opioid antagonist. Naloxone is an example of an opioid antagonist.
Talk with your doctor or pharmacist to learn more about using an opioid antagonist to reverse butorphanol’s effects.
How does butorphanol work? And how long does it take to start working?
Butorphanol works by binding to sites in the brain and spinal cord called opioid receptors. This causes the pain-relieving effects of the drug.
How quickly butorphanol starts to work depends on how it’s administered. For the nasal (nose) spray, pain relief usually starts within 15 minutes of administering a dose. It’ll also start working within 15 minutes when you receive it as an injection into a muscle. An injection into a vein will start working within a few minutes.
To find out more about what you can expect with butorphanol, ask your doctor or pharmacist.

Interactions and warnings for butorphanol
Below, you’ll find information about butorphanol’s possible interactions and warnings.
Interactions of butorphanol
For some medications, certain things may affect how the drug works. These include getting vaccines, consuming alcohol or certain foods, or taking the drug with other medications. This effect is called a drug interaction.
Before starting butorphanol, ask your doctor to check for possible interactions. They can check for interactions these items may cause with butorphanol. Be sure to tell them about any of the following you take or use:
- prescription drugs
- over-the-counter medications
- vitamins, herbs, or supplements
To learn about drug-condition interactions, see the “Warnings for butorphanol” section below.
Warnings for butorphanol
Butorphanol should not be administered to or should be administered cautiously by certain people.
Boxed warnings
Butorphanol has boxed warnings about the following risks. Boxed warnings are serious warnings from the Food and Drug Administration (FDA).
To learn more about these warnings, read below. You can also talk with your doctor or pharmacist.
Risk of addiction and misuse. With misuse, you use the drug in a way other than how a doctor prescribes it. This can lead to addiction. Addiction means continuing to use a drug even though it may be causing harm. It’s unknown how often these side effects were reported in studies* of butorphanol.
If you have concerns about treatment with butorphanol, tell your doctor. They’ll likely recommend ways to get help with misuse or addiction.
Risk of neonatal opioid withdrawal syndrome. With neonatal opioid withdrawal syndrome, withdrawal symptoms can occur in your baby if you were treated with butorphanol for a long time during pregnancy. (Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.) It’s unknown how often this side effect was reported in studies* of butorphanol.
Symptoms may include a high pitched cry, tremor, vomiting, and diarrhea in the newborn. These and other withdrawal symptoms can be life threatening.
If you become pregnant while taking butorphanol, tell your doctor. They’ll help you decide whether you should continue treatment with the drug.
Risk of serious respiratory depression. With serious respiratory depression, you have slowed or stopped breathing. This can be life threatening or fatal. This side effect was rarely reported in studies* of butorphanol.
The risk is highest when you first start treatment with butorphanol and after dosage increases. The risk is also higher for older adults (ages 65 years or over).
If you experience slowed or stopped breathing, seek immediate medical care or have someone call 911 for you.
Risk of serious accidental ingestion. With serious accidental ingestion, you can overdose on butorphanol. This can be life threatening. Accidentally ingesting butorphanol can be very dangerous in children.
Symptoms may include very small eye pupils, slow or shallow breathing, limp muscles, extreme sleepiness, or coma.
If you or someone else experiences accidental ingestion, seek immediate medical care or call 911.
Risk of harm if administered with benzodiazepines. If you administer benzodiazepines with butorphanol, you are at risk of coma and death. Benzodiazepines are central nervous system (CNS) depressants. This means they slow down your brain function. Other CNS depressants carry this same risk of harm if you use them with butorphanol. These CNS depressants include alcohol, other opioid pain relievers, and several other medications, such as zolpidem.
It’s unknown how often this side effect was reported in studies* of butorphanol. Symptoms may include slowed or stopped breathing, losing consciousness, and coma. In some cases, these symptoms can lead to death.
If you take benzodiazepines or drink alcohol, tell your doctor. They’ll likely recommend you stop taking benzodiazepines or stop consuming alcohol during butorphanol treatment.
Risk of harm if administered with certain other medications. With certain other medications, there is a risk of dangerous drug interactions. This includes drugs that affect the way your body processes and gets rid of butorphanol. Certain drugs can cause a high level of butorphanol in the body and increase the risk of serious side effects.
Certain other drugs can cause your butorphanol level to become too low. This could lead to withdrawal side effects and cause the drug not to work as well as it should. When you stop treatment with these types of drugs, the level of butorphanol could increase, raising the risk of serious side effects.
If you take other medications, tell your doctor. They’ll likely recommend changes to your dosage.
