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 has had an overdose, 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, brain tumor, 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 and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you use morphine injection with other 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.
Why is this medicine prescribed?
Morphine injection is used to relieve severe pain that cannot be controlled by the use of alternative pain medications, including oral opioid pain medications. 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 intravenously (into a vein) or intramuscularly (into a muscle). Morphine injection also may be injected intrathecally (into the fluid-filled space of the spinal canal) or by epidural injection (injection just outside of the fluid-filled space of the spinal canal) by a doctor in a medical office or clinic. If morphine is injected intravenously or intramuscularly, 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. Tell your doctor if you feel that your pain is not controlled or if your pain increases, becomes worse, or if you have new pain or an increased sensitivity to pain during your treatment with morphine. Do not use more of it or use it more often than prescribed by your doctor.
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. Your doctor will probably decrease your dose gradually.
What special precautions should I follow?
Before using morphine injection,
- tell your doctor and pharmacist if you are allergic to morphine, any other medications, or ingredients in morphine injection. Ask your pharmacist for a list of the ingredients.
- tell your doctor if you have or have ever had any of the conditions mentioned in the IMPORTANT WARNING section, a blockage or narrowing of your stomach or intestines, or paralytic ileus (condition in which digested food does not move through the intestines). Your doctor may tell you not to use morphine.
- tell your doctor if you have or have ever had seizures; low blood pressure; problems urinating; adrenal insufficiency (condition in which the adrenal glands do not produce enough of certain hormones needed for important body functions);or pancreas, gallbladder, heart, liver, or kidney disease.
- tell your doctor if you are breastfeeding. You should not breastfeed while you are using morphine. Morphine can cause shallow breathing, difficulty or noisy breathing, confusion, more than usual sleepiness, trouble breastfeeding, or limpness in breastfed infants.
- you should know that this medication may decrease fertility in men and women. Talk to your doctor about the risks of using morphine.
- you should know that this medication may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- you should know that morphine may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
- you should know that morphine may cause constipation. Talk to your doctor about changing your diet or using other medications to prevent or treat constipation while you are using morphine.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are using morphine.
What special dietary instructions should I follow?
Unless your doctor tells you otherwise, continue your normal diet.
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 using morphine injection, you should talk to your doctor about having a rescue medication called naloxone readily 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. Your doctor may also prescribe you naloxone if you are living in a household where there are small children or someone who has abused street or prescription drugs. Ask your doctor about other ways that you can obtain naloxone (directly from a pharmacy or as part of a community based program). You should make sure that you and your family members, caregivers, or the people who spend time with you know how to recognize 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 symptoms of an overdose occur, a friend or family member should give the 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
- difficulty breathing
- excessive sleepiness
- unable to respond or wake up
- limp or weak muscles
- cold, clammy skin
- narrowing or widening of the pupils (dark circle in the eye)
- slow heartbeat
- unusual snoring
What side effects can this medicine cause?
Morphine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- headache
- dizziness
- lightheadedness
- mood changes
- difficulty urinating
Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately or get emergency medical treatment:
- seizures
- slowed breathing

Morphine may cause other side effects. Call your doctor if you have any unusual problems while you are using this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online ( http://www.fda.gov/Safety/MedWatch ) or by phone (1-800-332-1088).
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, out of reach of children, and in a location that is not easily accessible by others, including visitors to the home. Store it at room temperature and away from excess heat and moisture (not in the bathroom). You must immediately dispose of any medication that is outdated or no longer needed through a medicine take-back program. If you do not have a take-back program nearby or one that you can access promptly, flush any meperidine injection solution that is outdated or no longer needed down the toilet. Talk to your pharmacist about the proper disposal of your medication.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
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.
