What is Butorphanol Tartrate?
From the FDA label:Butorphanol tartrate is a synthetically derived opioid agonist-antagonist analgesic of the phenanthrene series. The chemical name is (-)-17-(cyclobutylmethyl)morphinan-3,14-diol[S-(R*,R*)]-2,3-dihydroxybutanedioate (1:1) (salt). The molecular formula is C 21 H 29 NO 2 •C 4 H 6 O 6 , which corresponds to a molecular weight of 477.55 g/mol and the following structural formula: Butorphanol tartrate is a white crystalline substance. The dose is expressed as the tartrate salt. One milligram of the salt is equivalent to 0.68 mg of the free base. The n-octanol/aqueous buffer partition coefficient of butorphanol is 180:1 at pH 7.5. Butorphanol tartrate nasal spray, USP is an aqueous solution of butorphanol tartrate for administration as a metered spray to the nasal mucosa. Each bottle of butorphanol tartrate nasal spray, USP contains 2.5 mL of a 10 mg/mL solution of butorphanol tartrate with sodium chloride, citric acid, and benzethonium chloride in purified water with sodium hydroxide and/or hydrochloric acid added to adjust the pH to 5.0. The pump reservoir must be fully primed [see PATIENT INSTRUCTIONS ] prior to initial use. After initial priming each metered spray delivers an average of 1.0 mg of butorphanol tartrate and the 2.5 mL bottle will deliver an average of 14 to 15 doses of butorphanol tartrate nasal spray, USP. If not used for 48 hours or longer, the unit must be…
How to use
Butorphanol Tartrate is sold in more than one form (Injectable, Spray/Inhaler and Spray/Inhaler, metered), and each is dosed differently. The instructions below come from the FDA label for application ANDA075499 — follow the label that came with the product you were actually prescribed.
Important Dosage and Administration Instructions Butorphanol tartrate nasal spray should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see WARNINGS ]. Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of butorphanol tartrate nasal spray for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. There is variability in the opioid analgesic dose and duration needed to adequately manage pain due both to the cause of pain and to individual patient factors. Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse [see WARNINGS ]. Respiratory depression can occur at any time during opioid therapy,…
Side effects
Clinical Trial Experience A total of 788 patients were studied in premarketing clinical trials of butorphanol tartrate nasal spray. In nearly all cases the type and incidence of side effects with butorphanol were those commonly observed with opioid analgesics. The adverse experiences described below are based on data from short-term and long-term clinical trials in patients receiving intranasal butorphanol, except acute studies in normal subjects. There has been no attempt to correct for placebo effect or to subtract the frequencies reported by placebo-treated patients in controlled trials. The most frequently reported adverse experiences across all clinical trials with Butorphanol Tartrate Nasal Spray were somnolence (49%), dizziness (23%), nausea and/or vomiting (8%). In long-term trials with butorphanol tartrate nasal spray only, nasal congestion (13%) and insomnia (11%) were frequently reported. The following adverse experiences were reported at a frequency of 1% or greater in clinical trials and were considered to be probably related to the use of butorphanol. Body as a Whole: Asthenia/lethargy, headache, sensation of heat, pain. Cardiovascular: Hypertension, hypotension Digestive: Anorexia, constipation, dry mouth, nausea and/or vomiting, diarrhea. Nervous: Anxiety, confusion, dizziness, euphoria, floating feeling, insomnia, nervousness, paresthesia, somnolence, tremor…
FDA Boxed Warning (the FDA’s most serious warning)
Boxed (black-box) warning — from the FDA label
Addiction, Abuse, and Misuse Because the use of butorphanol tartrate nasal spray exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient’s risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions [see WARNINGS ]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of butorphanol tartrate nasal spray, especially during initiation or following a dose increase. To reduce the risk of respiratory depression, proper dosing and titration of butorphanol tartrate nasal spray are essential [see WARNINGS ]. Accidental Exposure Accidental exposure of even one dose of butorphanol tartrate nasal spray, especially in children, can result in a fatal overdose of butorphanol tartrate[see WARNINGS ]. Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of butorphanol tartrate nasal spray and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see WARNINGS , PRECAUTIONS ; Drug Interactions ]. Neonatal Opioid Withdrawal Syndrome If opioid use is required for an extended period of time in a pregnant woman, advise the patient of the risk of NOWS, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see WARNINGS] . Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS): Healthcare providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription [see WARNINGS ].
Warnings
Important safety information
Addiction, Abuse, and Misuse Butorphanol tartrate nasal spray contains butorphanol, a Schedule IV controlled substance. As an opioid, butorphanol tartrate nasal spray exposes users to the risks of addiction, abuse, and misuse [see DRUG ABUSE AND DEPENDENCE ]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed butorphanol tartrate nasal spray. Addiction can occur at recommended dosages and if the drug is misused or abused. Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing butorphanol tartrate nasal spray, and reassess all patients receiving butorphanol tartrate nasal spray for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as butorphanol tartrate nasal spray, but use in such patients necessitates intensive counseling about the risks and proper use of butorphanol tartrate nasal spray along with frequent reevaluation for signs of addiction, abuse, and misuse. Consider prescribing naloxone for the emergency treatment of opioid overdose (see WARNINGS , Life-Threatening Respiratory Depression ; DOSAGE AND ADMINISTRATION , Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose ). Opioids are sought for non-medical use and are subject to diversion from legitimate prescribed use. Consider these risks when prescribing or dispensing butorphanol tartrate nasal spray. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and proper disposal of unused drug. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status [see OVERDOSAGE ]. Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of butorphanol tartrate nasal spray, the risk is greatest during the initiation of therapy or following a dosage increase of butorphanol. To reduce the risk of respiratory depression, proper dosing and titration of butorphanol tartrate nasal spray are essential [see DOSAGE AND ADMINISTRATION ]. Overestimating the butorphanol tartrate nasal spray dosage when converting patients from another opioid product can result in a fatal overdose with the first dose. Accidental exposure to even one dose of butorphanol tartrate nasal spray, especially by children, can result in respiratory depression and death due to an overdose of butorphanol. Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose (see PRECAUTIONS , Information for Patients ). Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper [see DOSAGE AND ADMINISTRATION ]. Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing treatment with butorphanol tartrate nasal spray. Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program). Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help, even if naloxone is administered (see PRECAUTIONS , Information for Patients ). Consider prescribing naloxone, based on the patient’s risk factors for overdose, such as concomitant use of other CNS depressants, a history of opioid use disorder, or prior opioid overdose. The presence of risk factors for overdose should not prevent the proper management of pain in any given patient. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose. If naloxone is prescribed, educate patients and caregivers on how to treat with naloxone (see WARNINGS , Addiction, Abuse, and Misuse , Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants ; PRECAUTIONS , Information for Patients ). Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants Profound sedation, respiratory depression, coma, and death may result from the concomitant use of butorphanol tartrate nasal spray with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [see PRECAUTIONS; Drug Interactions ]. If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Inform patients and caregivers of this potential interaction, educate them on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose (see WARNINGS , Life-Threatening Respiratory Depression ; DOSAGE AND ADMINISTRATION , Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose ). Advise both patients and caregivers about the risks of respiratory depression and sedation when butorphanol tartrate nasal spray is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and…
Who should not take Butorphanol Tartrate
Butorphanol tartrate nasal spray is contraindicated in: Patients with significant respiratory depression [see WARNINGS ] Patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see WARNINGS ] Patients with known or suspected gastrointestinal obstruction, including paralytic ileus [see WARNINGS ] Patients with hypersensitivity to butorphanol tartrate, the preservative benzethonium chloride, or any of the formulation excipients (e.g., anaphylaxis) [see WARNINGS ])
Overdose — what happens if you take too much
Clinical Presentation Acute overdose with butorphanol tartrate nasal spray can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations. Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. Opioid antagonist, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to butorphanol tartrate overdose, administer an opioid antagonist. As butorphanol is a mixed opioid agonist/antagonist, larger doses of naloxone may be needed to reverse the effects of an overdose. Because the duration of opioid reversal is expected to be less than the duration of action of butorphanol in butorphanol tartrate nasal spray, carefully monitor…

Frequently asked questions
- What does Butorphanol Tartrate treat?
- Butorphanol Tartrate (Butorphanol Tartrate) may be used to treat pain, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
- How is Butorphanol Tartrate rated?
- pharmaranks gives Butorphanol Tartrate a composite score of 3.1 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.
- How much does Butorphanol Tartrate cost?

What IS published is what the pharmacy paid to acquire it: about $14.77 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Akten — about $0.23 on the same basis.
- Is there a coupon or discount for Butorphanol Tartrate?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Butorphanol Tartrate. To pay less, Butorphanol Tartrate is already a generic — usually the lowest-cost version — so the main levers are comparing cash prices between pharmacies and using a pharmacy discount-card service. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.

What people report to the FDA about Butorphanol Tartrate
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 393 reports naming Butorphanol Tartrate, and the FDA flagged 41% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- drug hypersensitivity48 reports
- nausea34 reports
- headache25 reports
- migraine20 reports
- pruritus17 reports
- vomiting17 reports
- anxiety15 reports
- dizziness15 reports
Read these as a signal, not a rate. A report does not mean Butorphanol Tartrate caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
