Morphine Injection

(mor' feen)

Brand Name(s): Astramorph® PF, Duramorph®, Infumorph®; also available generically

IMPORTANT WARNING:

Morphine injection may be habit forming, especially with prolonged use. Use morphine injection exactly as directed. Do not use more of it, use it more often, or use it in a different way than directed by your doctor. While you are using morphine, discuss with your health care provider your pain treatment goals, length of treatment, and other ways to manage your pain. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse morphine if you have or have ever had any of these conditions. Talk to your health care provider immediately and ask for guidance if you think that you have an opioid addiction or call the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-HELP.

Morphine may cause serious or life-threatening breathing problems, especially during the first 24 to 72 hours of your treatment and any time your dose is increased. Your doctor will monitor you carefully during your treatment. Tell your doctor if you have or have ever had slowed breathing or asthma. Your doctor will probably tell you not to use morphine injection. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways), a head injury, or any condition that increases the amount of pressure in your brain. The risk that you will develop breathing problems may be higher if you are an older adult or are weak or malnourished due to disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.

Taking certain medications during your treatment with morphine injection may increase the risk that you will experience serious or life-threatening breathing problems, sedation, or coma. Tell your doctor if you are taking or plan to take any of the following medications: benzodiazepines such as alprazolam (Xanax), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), and triazolam (Halcion); medications for mental illness nausea or pain; muscle relaxants; sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you use morphine injection with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.

Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with morphine injection increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol, take prescription or nonprescription medications that contain alcohol, or use street drugs during your treatment.

Do not allow anyone else to use your medication. Morphine may harm or cause death to other people who use your medication, especially children.

Tell your doctor if you are pregnant or plan to become pregnant. If you use morphine regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.

Talk to your doctor about the risks of using morphine injection.

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: https://bit.ly/3hzDavc, 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: https://bit.ly/3hx8tXG, 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.

RECOMMENDATION:

Patients:

  • 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: https://www.usa.gov/state-health, 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.

WHY is this medicine prescribed?

Morphine injection is used to relieve moderate to severe pain. Morphine is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Morphine injection comes as a solution (liquid) to inject intramuscularly (into a muscle) or intravenously (into a vein). It is usually injected once every 4 hours as needed. Use morphine injection at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use morphine injection exactly as directed.

Your doctor may adjust your dose of morphine injection during your treatment, depending on how well your pain is controlled and on the side effects that you experience. Talk to your doctor about how you are feeling during your treatment with morphine injection.

If you have used morphine injection for longer than a few days, do not stop using it suddenly. If you suddenly stop using morphine injection, you may experience withdrawal symptoms including restlessness; teary eyes; runny nose; yawning; sweating; chills; muscle, back or joint pain; widening of the pupils; irritability; anxiety; weakness; stomach cramps; difficulty falling asleep or staying asleep; nausea; loss of appetite; vomiting; diarrhea; fast breathing; or fast heartbeat.

What should I do in case of OVERDOSE?

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

While you are using morphine injection, you may be told to always have a rescue medication called naloxone available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. You will probably be unable to treat yourself if you experience an opiate overdose. You should make sure that your family members, caregivers, or the people who spend time with you know how to tell if you are experiencing an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If someone sees that you are experiencing symptoms of an overdose, he or she should give you your first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.

Symptoms of overdose may include the following:

  • slow, shallow, or irregular breathing
  • sleepiness
  • loss of consciousness
  • cold, clammy skin
  • small pupils
  • slow heartbeat
  • blurred vision
  • nausea
  • fainting

What OTHER INFORMATION should I know?

Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your body's response to morphine.

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

This prescription is not refillable. If you are using morphine to control your pain on a long term basis, be sure to schedule appointments with your doctor so that you do not run out of medication. If you are using morphine on a short-term basis, call your doctor if you continue to experience pain after you finish the medication.

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