TOPIC: Opioid Pain Relievers or Medicines to Treat Opioid Use Disorder: MedWatch Safety Alert – FDA Recommends Health Care Professionals Discuss Naloxone with All Patients when Prescribing.

AUDIENCE: Patient, Health Professional, Pharmacy

ISSUE: FDA is requiring drug manufacturers for all opioid pain relievers and medicines to treat opioid use disorder (OUD) to add new recommendations about naloxone to the prescribing information. This will help ensure that health care professionals discuss the availability of naloxone and assess each patient’s need for a naloxone prescription when opioid pain relievers or medicines to treat OUD are being prescribed or renewed. The patient Medication Guides, available at:, will also be updated.

BACKGROUND: Opioid pain relievers are medicines that can help manage pain when other treatments and medicines are not able to provide enough pain relief. Certain opioids are also used to treat OUD. Opioids have serious risks, including misuse and abuse, addiction, overdose, and death. Naloxone can help reverse opioid overdose to prevent death.

The misuse and abuse of illicit and prescription opioids and the risks of addiction, overdose, and death are a public health crisis in the United States. As a result, FDA is committed to encouraging health care professionals to raise awareness of the availability of naloxone when they are prescribing and dispensing opioid pain relievers or medicines to treat OUD. FDA held discussions about naloxone availability with the Anesthetic and Analgesic Drug Products and the Drug Safety and Risk Management Advisory Committees, available at:, which recommended that all patients being prescribed opioids for use in the outpatient setting would benefit from a conversation with their health care professional about the availability of naloxone.



  • Talk to your health care professionals about the benefits of naloxone and how to obtain it.
  • Recognize the signs and symptoms of a possible opioid overdose. These include slowed, shallow, or difficult breathing, severe sleepiness, or not being able to respond or wake up. If you know or think someone is overdosing, give the person naloxone if you have access to it, and always call 911 or go to an emergency room right away. Naloxone is a temporary treatment, so repeat doses may be required. Even if you give naloxone, you still need to get emergency medical help right away.
  • If you have naloxone, make sure to tell your caregivers, household members, and other close contacts that you have it, where it is stored, and how to properly use it in the event of an overdose. When using opioid medicines away from home, carry naloxone with you and let those you are with know you have it, where it is, and how to use it. Read the Patient Information leaflet or other educational material and Instructions for Use that comes with your naloxone because it explains important information, including how to use the medicine.

Health Care Professionals:

  • Discuss the availability of naloxone with all patients when prescribing or renewing an opioid analgesic or medicine to treat OUD.
  • Consider prescribing naloxone to patients prescribed medicines to treat OUD and patients prescribed opioid analgesics who are at increased risk of opioid overdose.
  • Consider prescribing naloxone when a patient has household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose.
  • Additionally, even if the patients are not receiving a prescription for an opioid analgesic or medicine to treat OUD, consider prescribing naloxone to them if they are at increased risk of opioid overdose.
  • Educate patients and caregivers on how to recognize respiratory depression and how to administer naloxone. Inform them about their options for obtaining naloxone as permitted by their individual state, available at:, dispensing and prescribing requirements or guidelines for naloxone. Emphasize the importance of calling 911 or getting emergency medical help right away, even if naloxone is administered.

What should I know about storage and disposal of this medication?

If you are using Stadol at home, keep the medicine in the container it came in, tightly closed, and out of the reach of children. Store at room temperature and away from light, excess heat, and moisture (not in the bathroom). Throw away any medicine that is out of date or no longer needed. Talk to your pharmacist about the correct way to dispose of your medicine.

Store Stadol in a safe place so that no one else can use it accidentally or on purpose. Keep track of how much medicine is left to see if any are missing.

It is important to keep all medicines out of the sight and reach of children, as many containers (such as those containing weekly pills and those for eye drops, creams, patches, and inhalers) are not child-resistant and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach.

In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at

If the victim collapsed, had a seizure, has trouble breathing, or cannot wake up, immediately call 911 for emergency services.

While using Stadol, you may be told to always have a rescue medicine called naloxone available (for example, at home, in the office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opioids to relieve dangerous symptoms caused by high levels of opiates in the blood. You will probably not be able to treat yourself if you experience an opioid overdose. You should make sure that your family members, caregivers, or the people who spend time with you know how to know if you are experiencing an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will teach you and your family members how to use the medicine. Ask your pharmacist for instructions or visit the manufacturer’s website for instructions. If someone sees that you are experiencing symptoms of an overdose, they should give you your first dose of naloxone, call 911 immediately, stay with you, and monitor you closely until emergency medical help arrives. Your symptoms may return within minutes after receiving naloxone. If their symptoms return, the person should give them another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms reappear before medical help arrives.

Symptoms of overdose may include the following:

  • slow or shallow breathing
  • coma (loss of consciousness for a period of time)
  • death

What other information should I know?

Keep all appointments with your doctor and laboratory. Your doctor will order certain laboratory tests to check your body’s response to butorphanol (Stadol).

Before having any laboratory test (especially those that involve methylene blue), tell your doctor and the laboratory personnel that you are receiving butorphanol (Stadol).

Do not let anyone use your medicine. If you continue to have pain after you finish your Stadol, call your doctor.

It is important that you keep a written list of all prescription and over-the-counter (over-the-counter) medications you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should take this list with you each time you visit a doctor or if you go into hospital. It is also important information to take with you in case of emergencies.
