MS Contin (morphine) is an opioid pain medication. An opioid is sometimes called a narcotic.
MS Contin extended-release tablets are a strong prescription pain medicine used to treat moderate to severe pain that requires around-the-clock, long-term treatment. MS Contin is used when other pain treatments such as non-opioid pain medicines or immediate-release opioid medicines do not treat the pain well enough or cannot be tolerated.
MS Contin extended-release tablets are 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 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, 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.
