Physicians should expect side effects and treat patients accordingly.

All opioids, including MS Contin, put patients at risk for the serious breathing condition, respiratory depression. During respiratory depression, the lungs do not adequately exchange oxygen, carbon dioxide and other blood gases. Symptoms of respiratory depression include slow or shallow breathing, unusual breathing patterns, gasping or wheezing, and a bluish tint around the eyes, mouth and fingertips.

Most Frequently Observed

The most frequently observed MS Contin side effects are constipation, lightheadedness, dizziness, sedation, nausea, vomiting, sweating, sadness and euphoria. Consumers who are able to walk on their own, or who were not in significant pain when they took MS Contin, are more likely to experience these side effects than are those confined to a bed or wheelchair. Lying down usually eases these side effects.

Nervous system

MS Contin works directly on the part of the brain responsible for breathing, increasing the risk for respiratory depression. Doctors treat respiratory depression with naloxone to lower MS Contin levels.

MS Contin frequently causes other CNS side effects, including drowsiness and sedation. Less frequently, MS Contin consumers have reported delirium, seizures, tremors, dizziness, muscle twitches or muscle rigidity, malaise and confusion. Other CNS side effects include weakness, headache, agitation and changes in mood such as nervousness or depression.
