BUTORPHANOL TARTRATE - NASAL
(bue-TOR-fa-nol TAR-trate)
COMMON BRAND NAME(S): Stadol NS
WARNING: Butorphanol has a risk for abuse and addiction, which can lead to overdose and death. Butorphanol may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you use the smallest dose of butorphanol that works, and use it for the shortest possible time. See also How to Use section for more information about addiction.The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you use the wrong dose/strength. Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Also, other medications can affect the removal of butorphanol from your body, which may affect how butorphanol works. Be sure you know how to use butorphanol and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.Keep this medicine in a safe place to prevent theft, misuse, or abuse. If someone accidentally swallows or uses this drug, get medical help right away.Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits. Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It may slightly increase the risk of birth defects if used during the first two months of pregnancy. Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, use the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms. Tell the doctor right away if you notice any symptoms in your newborn baby such as crying that doesn't stop, slow/shallow breathing, irritability, shaking, vomiting, diarrhea, poor feeding, or difficulty gaining weight.
USES: This medication is used to treat moderate to severe pain, including pain from surgery, muscle pain, and migraine headaches. Butorphanol is an opioid pain reliever similar to morphine. It acts on certain centers in the brain to give you pain relief.Butorphanol can also block the effects of opioids and can cause withdrawal symptoms in people dependent on opioids. If possible, people who have recently used opioids in high doses or for a long time should not use butorphanol. (See also Side Effects section.)
HOW TO USE: Read the Medication Guide and the Patient Information Leaflet provided by your pharmacist before you start using butorphanol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.This medication is a nasal spray. Have your doctor or pharmacist show the proper way to use the nasal spray. For best results, blow your nose gently before using. Follow the patient instruction leaflet for priming the pump before first use. If the spray has not been used in 48 hours, you may need to prime the pump again before use.Use 1 spray in 1 nostril or as directed by your doctor. If you still have pain after 60-90 minutes, your doctor may direct you to use a second spray in the other nostril. If needed, butorphanol may be used again in 3-4 hours after the second spray or as directed by your doctor. Some people will need 2 sprays (1 in each nostril) at the same time. In this case, they should remain lying down because there is a higher risk of drowsiness and dizziness with this higher dose. Follow your doctor's directions carefully.The dosage is based on your medical condition and response to therapy. Do not increase the dose or use it more often than directed by your doctor. Pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.This drug can cause a drop in blood pressure, especially within the first hour after use. This can cause dizziness, lightheadedness, and fainting. To lower this risk, remain sitting or lying down after using this medication.If you use a nasal decongestant spray (e.g., oxymetazoline), the decongestant may make this pain medication work more slowly. Ask your doctor or pharmacist about using these 2 medications.If you have nausea, ask your doctor or pharmacist about ways to decrease it (such as lying down for 1 to 2 hours with as little head movement as possible).Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.Though it helps many people, this medication may sometimes cause addiction. This risk may be higher if you have a substance use disorder (such as overuse of or addiction to drugs/alcohol). Use this medication exactly as prescribed to lower the risk of addiction. Ask your doctor or pharmacist for more details.When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.Tell your doctor if your pain does not get better or if it gets worse.
SIDE EFFECTS: See also Warning section.Drowsiness, dizziness, blurred vision, flushing, headache, nausea, vomiting, constipation, nasal irritation/congestion, trouble sleeping, dry mouth, and sweating may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.To prevent constipation, eat dietary fiber, drink enough water, and exercise. You may also need to take a laxative. Ask your pharmacist which type of laxative is right for you.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Butorphanol can cause withdrawal reactions in people who are physically dependent on opioids. The seriousness of the withdrawal symptoms depends on the level of dependence and the dose of butorphanol. Tell your doctor right away if you develop symptoms such as anxiety, agitation, trouble sleeping, sweating, stomach cramps, and diarrhea.Tell your doctor right away if you have any serious side effects, including: bleeding from the nose, interrupted breathing during sleep (sleep apnea), mental/mood changes (e.g., anxiety, confusion, hallucinations), fast/slow/irregular heartbeat, severe stomach/abdominal pain, difficulty urinating, signs of your adrenal glands not working well (such as loss of appetite, unusual tiredness, weight loss).Get medical help right away if you have any very serious side effects, including: difficult/slow/shallow breathing, severe drowsiness/difficulty waking up, seizures.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.

This product may contain inactive ingredients (such as benzethonium chloride), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: abdominal problems (e.g., gallbladder disease, pancreatitis), adrenal gland problems (e.g., Addison's disease), brain disorders (e.g., seizures, head injury, tumor, increased intracranial pressure), heart problems (e.g., irregular heartbeat, chest pain, recent heart attack), high blood pressure, kidney disease, liver disease, breathing problems (e.g., asthma, chronic obstructive pulmonary disease-COPD, sleep apnea), mental/mood disorders (e.g., toxic psychosis), a certain spinal problem (kyphoscoliosis), stomach/intestinal problems (such as diarrhea due to infection, paralytic ileus), personal or family history of a substance use disorder (such as overuse of or addiction to drugs/alcohol), difficulty urinating (e.g., due to enlarged prostate or urethral stricture), underactive thyroid (hypothyroidism).This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).To lower your risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Older adults may be more sensitive to the side effects of this drug, especially confusion, dizziness, drowsiness, and slow/shallow breathing.During pregnancy, this medication should be used only when clearly needed. It may harm an unborn baby. Discuss the risks and benefits with your doctor. (See also Warning section.)This drug passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: See also Warning section.Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug include: MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine), naltrexone, nasal decongestants (e.g., oxymetazoline).The risk of serious side effects (such as slow/shallow breathing, severe drowsiness/dizziness) may be increased if this medication is used with other products that may also cause drowsiness or breathing problems. Tell your doctor or pharmacist if you are taking other products such as other opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.Other medications can affect the removal of butorphanol from your body, which may affect how butorphanol works. Examples include azole antifungals (such as ketoconazole), macrolide antibiotics (such as erythromycin), HIV medications (such as ritonavir), rifamycins (such as rifabutin, rifampin), certain drugs used to treat seizures (such as carbamazepine, phenytoin), among others.This medication may interfere with certain laboratory tests (including amylase/lipase levels), possibly causing false test results.
