This tip comes from a pain management colleague of mine.
If you have a patient on chronic opioid therapy, consider having them take magnesium 500mg twice a day.
Magnesium will help reduce the need to increase the patient’s opioid dose due to developing a tolerance and also help prevent the constipation associated with chronic opioid use.
Additionally, magnesium is a muscle relaxant and could potentially help reduce muscle spasm in chronic pain sufferers.
One of the best parts? Its dirt cheap as well!
