Too much MS Contin could be very harmful. 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 tablet. Swallow the pill whole. It will release medicine slowly in the body.

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

Since MS Contin is sometimes used as needed, you may not be on a dosing schedule. If you are using the medication regularly, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.
