What should be done if myoclonus occurs during morphine treatment?

In cases where myoclonus develops as a side effect of morphine treatment, switching to another opioid is a recommended course of action. Myoclonus, which refers to sudden, involuntary muscle jerks, can be exacerbated by morphine in some patients, indicating that the individual may not tolerate this medication well.

Different opioids have distinct pharmacologic profiles and side effect management potentials. By changing to another opioid, the healthcare provider can potentially find an alternative that minimizes the risk of myoclonus while still effectively managing pain. This adjustment can also provide relief from other side effects that may be associated with morphine.

The other options presented have drawbacks that make them less appropriate. Increasing the dose of morphine may worsen myoclonus, so it is generally not advised. Applying heat to the affected area may provide temporary relief but does not address the underlying cause, and continuing treatment as prescribed without modification risks further complications and discomfort for the patient. Thus, switching to another opioid is a targeted response that seeks to mitigate the specific side effect experienced.
