Usage of MS Contin

MS Contin (morphine) is a strong prescription pain medicine used for around-the-clock, long-term treatment of moderate to severe pain in adults. MS Contin is used when other pain treatments do not treat the pain well enough or cannot be tolerated.

MS Contin should not be used to treat pain that can be controlled by medication that is taken as needed.

MS Contin belongs to a class of medicines called opiate (narcotic) analgesics. Morphine works by changing the way the brain and nervous system respond to pain.

MS Contin side effects

Get emergency medical help if you have signs of an allergic reaction to MS Contin: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Opioid medicine can slow or stop your breathing, and death may occur, especially if you drink alcohol or use other drugs that cause drowsiness or slow breathing. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Morphine may cause serious side effects. Call your doctor at once if you have:

slow heart rate, weak pulse, fainting, slow breathing (breathing may stop);

chest pain, fast or pounding heartbeats;

extreme drowsiness, feeling like you might pass out; or

decreased adrenal gland hormones - nausea, vomiting, stomach pain, loss of appetite, feeling tired or light-headed, muscle or joint pain, skin discoloration, craving salty foods.

Serious breathing problems may be more likely in older adults and people who are debilitated or have wasting syndrome or chronic breathing disorders.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Common MS Contin side effects may include:

drowsiness, dizziness, tiredness, anxiety;

nausea, vomiting, stomach pain, gas, or constipation;

sweating, low oxygen levels (shortness of breath), feeling light-headed; or

feelings of extreme happiness or sadness.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking MS Contin

You should not take MS Contin if you have ever had an allergic reaction to morphine or other opioid medicines, or if you have:

severe asthma or breathing problems;

a stomach or bowel obstruction (including paralytic ileus); or

if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, or tranylcypromine.

To make sure MS Contin is safe for you, tell your doctor if you have ever had:

chronic obstructive pulmonary disease (COPD), sleep apnea, or other breathing disorder;

a head injury, brain tumor, high pressure inside the skull, or seizures;

a drug or alcohol addiction, or mental illness;

urination problems;

problems with your bile duct, gallbladder, pancreas, thyroid, or adrenal gland; or

liver or kidney disease.

Tell your doctor if you also use stimulant medicine, other opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with morphine could cause a serious condition called serotonin syndrome.

Morphine may harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. If you use MS Contin during pregnancy, your baby could be born with life-threatening withdrawal symptoms, and may need medical treatment for several weeks.

Long-term morphine use may affect fertility in men or women. Pregnancy could be harder to achieve while either parent is using MS Contin.

Do not breastfeed. Morphine in breast milk can cause life-threatening side effects in a nursing baby.
