Description
Morphine injection is used to treat pain severe enough to require opioid treatment and when other pain medicines did not work well enough or cannot be tolerated. It may also be used before or during surgery with an anesthetic (medicine that puts you to sleep). Morphine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.
When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
This medicine is to be given only by or under the immediate supervision of your doctor.
This product is available in the following dosage forms:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of morphine injection in children 1 month of age and older. Safety and efficacy in infants younger than 1 month of age have not been established.
Appropriate studies have not been performed on the relationship of age to the effects of morphine injection in the pediatric population. Safety and efficacy have not been established. Use of morphine epidural injection is not recommended in children.
Geriatric

Proper Use
A nurse or other trained health professional will give you this medicine in a hospital. This medicine may be given as a shot under the skin, as a shot into one of your muscles, or through an IV catheter placed in one of your veins. It can also be given through a needle or catheter into your back.
Your doctor will give you a few doses of this medicine until your condition improves, and then switch you to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
Precautions
It is very important that your doctor check the progress of you or your child while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to use it. Blood and urine tests may be needed to check for unwanted effects.
Do not use this medicine if you are using or have used an MAO inhibitor (MAOI) such as isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.
Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.
This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea while using this medicine.
Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn baby. Check with your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.
Call your doctor right away if you have worsening of pain, increased sensitivity to pain, or new pain after taking this medicine. These may be symptoms of opioid-induced hyperalgesia and allodynia.
This medicine may be habit-forming. If you or your child feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you or your child to take laxatives, drink a lot of fluids, or increase the amount of fiber in the diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.
This medicine may cause adrenal gland problems. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.
Dizziness, lightheadedness, or fainting may occur when you or your child get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.
This medicine may make you dizzy, drowsy, confused, or disoriented. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you or your child are using this medicine. Serious unwanted effects can occur if certain medicines are given together with morphine injection.
If you or your child have been using this medicine regularly for several weeks or longer, do not suddenly stop using it without checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, including stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble with sleeping.
Check with your doctor right away if you or your child have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.
Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
