AUDIENCE: Pharmacy, Internal Medicine, Psychiatry, Neurology, Family Practice
ISSUE: FDA review has found that the growing combined use of opioid medicines with benzodiazepines or other drugs that depress the central nervous system (CNS) has resulted in serious side effects, including slowed or difficult breathing and deaths. Opioids are used to treat pain and cough; benzodiazepines are used to treat anxiety, insomnia, and seizures. In an effort to decrease the use of opioids and benzodiazepines, or opioids and other CNS depressants, together, FDA is adding Boxed Warnings, our strongest warnings, to the drug labeling of prescription opioid pain and prescription opioid cough medicines, and benzodiazepines. See the Drug Safety Communication, available at: http://www.fda.gov/Drugs/DrugSafety/ucm518473.htm, for a listing of all approved prescription opioid pain and cough medicines, and benzodiazepines and other CNS depressants.
FDA conducted and reviewed several studies showing that serious risks are associated with the combined use of opioids and benzodiazepines, other drugs that depress the CNS, or alcohol (see the FDA Drug Safety Communication, available at: http://www.fda.gov/Drugs/DrugSafety/ucm518473.htm, for a Data Summary). Based on these data, FDA is requiring several changes to reflect these risks in the opioid and benzodiazepine labeling, and new or revised patient Medication Guides. These changes include the new Boxed Warnings and revisions to the Warnings and Precautions, Drug Interactions, and Patient Counseling Information sections of the labeling.
FDA is continuing to evaluate the evidence regarding combined use of benzodiazepines or other CNS depressants with medication-assisted therapy (MAT) drugs used to treat opioid addiction and dependence. FDA is also evaluating whether labeling changes are needed for other CNS depressants, and will update the public when more information is available.
BACKGROUND: Opioids are powerful prescription medicines that can help manage pain when other treatments and medicines cannot be taken or are not able to provide enough pain relief. Benzodiazepines are a class of medicines that are widely used to treat conditions including anxiety, insomnia, and seizures.
RECOMMENDATION: Health care professionalsshould limit prescribing opioid pain medicines with benzodiazepines or other CNS depressants only to patients for whom alternative treatment options are inadequate. If these medicines are prescribed together, limit the dosages and duration of each drug to the minimum possible while achieving the desired clinical effect. Warn patients and caregivers about the risks of slowed or difficult breathing and/or sedation, and the associated signs and symptoms. Avoid prescribing prescription opioid cough medicines for patients taking benzodiazepines or other CNS depressants, including alcohol.
Patients taking opioids with benzodiazepines, other CNS depressant medicines, or alcohol, and caregivers of these patients, should seek medical attention immediately if they or someone they are caring for experiences symptoms of unusual dizziness or lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness.

Why is this medication prescribed?
Butorphanol nasal spray is used to relieve moderate to severe pain. Butorphanol is in a class of medications called opioid agonist-antagonists. It works by changing the way the body senses pain.
How should this medicine be used?
Butorphanol nasal spray comes as a solution (liquid) to spray in the nose. It is usually used as needed for pain, but not more often than once every 3 to 4 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Butorphanol nasal spray should relieve your pain soon after you use it. If you are using a low starting dose of butorphanol nasal spray, your doctor may tell you that you may use a second dose if you still have pain 60 to 90 minutes after your first dose. Do not use this second dose unless your doctor tells you that you may. Call your doctor if you still have pain after using butorphanol nasal spray as prescribed. Also call your doctor if you have used butorphanol nasal spray for some time and find that it no longer works as well as it did at the beginning of your treatment.
Butorphanol nasal spray may be habit-forming. Use butorphanol nasal spray exactly as directed. Do not use a larger dose or use it more often or for a longer time than prescribed by your doctor. Call your doctor if you develop a strong desire to use more medication than prescribed.
Do not stop using butorphanol nasal spray without talking to your doctor. If you suddenly stop using butorphanol nasal spray, you may experience withdrawal symptoms such as nervousness, agitation, shakiness, diarrhea, chills, sweats, difficulty falling asleep or staying asleep, loss of coordination,confusion, or hallucinations (seeing things or hearing voices that do not exist). Your doctor will probably decrease your dose gradually.
Before you use butorphanol nasal spray for the first time, read the written directions provided by the manufacturer. Ask your doctor or pharmacist if you have any questions about how to use butorphanol nasal spray.
To use butorphanol nasal spray, follow these directions:
- Wash your hands.
- Gently blow your nose.
- Remove the clear cover and protective clip from the bottle.
- If you are using a new pump or a pump that has not been used in 48 hours or longer, you must prime the pump before use. Hold the bottle so that the nozzle is between your first and second fingers and your thumb is on the bottom. Be sure that the bottle is aimed away from you, other people, and animals. Pump the bottle firmly and quickly (up to 8 strokes) until a fine spray appears.
- Insert the tip of the sprayer approximately 1/4 inch (0.6 cm) into one nostril, pointing the tip toward the back of your nose.
- Close your other nostril with your finger and tilt your head slightly forward.
- Pump the spray firmly and quickly one time and sniff gently with your mouth closed.
- Remove the sprayer from your nose. Tilt your head backward and sniff gently for a few seconds.
- Replace the protective clip and cover on the spray bottle. Put the bottle back in the child-resistant storage container.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with butorphanol nasal spray and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/cder) to obtain the Medication Guide.
