Generic Name:morphine sulfate controlled-release tablets: MS Contin
What is MS Contin?
MS Contin (morphine) is an opioid pain medication. An opioid is sometimes called a narcotic.
Extended-release MS Contin tablets are used when around-the-clock pain relief is needed. This form of morphine is not for use on an as-needed basis for pain.
MS Contin may also be used for purposes not listed in this medication guide.
You should not take MS Contin 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, especially when you start using this medicine or whenever your dose is changed. Never take MS Contin in larger amounts, or for longer than prescribed. Do not crush or break an extended-release tablet. Swallow it whole to avoid exposure to a potentially fatal dose.
MS Contin may be habit-forming, even at regular doses. Take this medicine exactly as prescribed by your doctor. Never share MS Contin with another person. MISUSE OF NARCOTIC PAIN MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Tell your doctor if you are pregnant. Morphine may cause life-threatening addiction and withdrawal symptoms in a newborn.
Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with MS Contin.
Before using MS Contin
You should not take MS Contin if you have ever had an allergic reaction to morphine or other narcotic medicines, or if you have:
severe asthma or breathing problems;
a blockage in your stomach or intestines; or
a bowel obstruction called paralytic ileus.
Do not use MS Contin 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.
You may not be able to take MS Contin if you are NOT already being treated with a similar opioid (narcotic) pain medicine and are tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.
Morphine may be habit-forming. Never share morphine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. Selling or giving away MS Contin to any other person is against the law.
To make sure MS Contin is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
a history of head injury, brain tumor, or seizures;
a history of drug abuse, alcohol addiction, or mental illness;
liver or kidney disease; or
problems with your gallbladder, pancreas, or thyroid.
MS Contin is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.
FDA pregnancy category C. It is not known whether MS Contin will harm an unborn baby. Morphine may cause breathing problems, behavior changes, or life-threatening addiction and withdrawal symptoms in your newborn if you use the medication during pregnancy. Tell your doctor if you are pregnant.

Morphine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How should I use MS Contin?
Morphine may be habit-forming, even at regular doses. Take MS Contin exactly as prescribed by your doctor. MISUSE OF NARCOTIC PAIN MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH.
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 take MS Contin in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Always check your bottle to make sure you have received the correct pills (same brand and type) of medicine prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
Stop taking all other around-the-clock narcotic pain medications when you start taking MS Contin.
Do not crush, chew, or break a MS Contin 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 a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Take the medicine at the same time each day.
Do not stop using MS Contin suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using MS Contin.
Never crush or break a MS Contin tablet to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death.
Store at room temperature, away from heat, moisture, and light.
Keep track of the amount of medicine used from each new bottle. Morphine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
After you have stopped using MS Contin, flush any unused tablets down the toilet. Disposal of medicines by flushing is recommended to reduce the danger of accidental overdose causing death. This advice applies to a very small number of medicines only. The FDA, working with the manufacturer, has determined this method to be the most appropriate route of disposal and presents the least risk to human safety.
What happens if I miss a dose?
MS Contin is normally taken 2 or 3 times per day. Since MS Contin is used for pain, you are not likely to miss a dose. If you do miss a dose, take the medicine as soon as you remember. Then take your next dose as follows:
If you take MS Contin 3 times per day: Take your next dose 8 hours after taking the missed dose.
If you take MS Contin 2 times per day: Take your next dose 12 hours after taking the missed dose.
Do not take extra medicine to make up a missed dose. Do not take more than your prescribed dose in a 24-hour period.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A morphine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, and fainting.
What should I avoid?
Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with morphine. Check your food and medicine labels to be sure these products do not contain alcohol.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how MS Contin will affect you. Dizziness or severe drowsiness can cause falls or other accidents.

What other drugs will affect MS Contin?
Taking this medicine with other drugs that make you sleepy or slow your breathing can cause dangerous or life-threatening side effects. Ask your doctor before taking MS Contin with a sleeping pill, other narcotic pain medicine, muscle relaxer, or medicine for anxiety, depression, or seizures.
