What is morphine?
Morphine is an opioid pain medication. An opioid is sometimes called a narcotic.
Morphine is used to treat moderate to severe pain. Short-acting formulations are taken as needed for pain.
The extended-release form of morphine is for around-the-clock treatment of pain. This form of morphine is not for use on an as-needed basis for pain.
You should not take morphine if you have severe asthma or breathing problems, a blockage in your stomach or intestines, or a bowel obstruction called paralytic ileus.
Morphine can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not take this medicine if you have ever had an allergic reaction to morphine or other narcotic medicines, or if you have:
- severe asthma or breathing problems; or
- a blockage in your stomach or intestines.
Do not use morphine if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
To make sure morphine is safe for you, tell your doctor if you have ever had:
- any type of breathing problem or lung disease;
- a head injury, brain tumor, or seizures;
- a drug or alcohol addiction, or mental illness;
- urination problems;
- liver or kidney disease;
- problems with your gallbladder, pancreas, or thyroid; or
- if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others).
Some medicines can interact with morphine and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
How should I use morphine?
Take morphine exactly as prescribed by your doctor. Follow all directions on your prescription label. Morphine can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never use this medicine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Morphine may be habit-forming. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away morphine is against the law.
Stop taking all other around-the-clock narcotic pain medications when you start taking morphine.
Do not crush, chew, or break an extended-release tablet. Swallow it whole to avoid exposure to a potentially fatal dose.
To make swallowing easier, you may open the extended-release capsule and sprinkle the medicine into a spoonful of applesauce. Swallow right away without chewing. Do not save the mixture for later use.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Do not stop using morphine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Never crush or break a tablet or capsule to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death with the misuse of morphine and similar prescription drugs.
Store at room temperature, away from heat, moisture, and light. Keep track of your medicine. Morphine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover pills or liquid. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush any unused pills or liquid medicine down the toilet.
