Novocain and MS-Contin



I am taking MS-Contin under a doctors care for chronic pain. Does this medicine interfere with novacain used in a dentists office for a filling? If so what does a dentist use to numb the patients mouth?


MS-Contin is a long-acting form of morphine, taken by mouth, which is often used for chronic pain conditions. Novocain is the trade name for the local anesthetic procaine. Procaine was one of the first local anesthetics developed, and the trade name has become synonymous with local anesthetics in general. Novocain, and other commonly used local anesthetics do not interfere with morphine. Pain killers may of course help to dull any dental pain that occurs after the dentist is done. You are unlikely to have a problem relating to your use of MS-Contin at the dentist`s office.
