Important information about MS Contin
You may not be able to take MS Contin unless you are already being treated with a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.
Morphine may be habit-forming and should be used only by the person it was prescribed for. Keep the medication in a secure place where others cannot get to it. Do not drink alcohol while you are using MS Contin. Dangerous side effects or death can occur when alcohol is combined with MS Contin. Check your food and medicine labels to be sure these products do not contain alcohol.
Never take MS Contin in larger amounts, or for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Do not stop using MS Contin suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using MS Contin.
Before using MS Contin
Do not use MS Contin if you have ever had an allergic reaction to a narcotic medicine (examples include methadone, morphine, Oxycontin, Darvocet, Percocet, Vicodin, Lortab, and many others), or to a narcotic cough medicine that contains codeine, hydrocodone, or dihydrocodeine. You should also not take MS Contin if you are having an asthma attack, or if you have a bowel obstruction called paralytic ileus.
Do not use MS Contin if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.

How should I use MS Contin?
Take MS Contin exactly as prescribed. Never take MS Contin in larger amounts, or for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Do not crush, chew, or break an extended-release MS Contin tablet. Swallow the tablet whole. It will release medicine slowly in the body. Breaking the tablet would cause too much of the drug to be released at one time.
Do not stop using MS Contin suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.

After you have stopped using MS Contin, flush any unused pills 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.
