Myth-buster
In a 104-patient trial, 250 mg of magnesium daily led to significantly higher narcotic use than a common painkiller after anorectal surgery.
This single, small RCT suggests magnesium may not be a straightforward opioid-sparing option in this specific surgical context — but the finding is preliminary and contradicts broader expectations, so it doesn't settle the question.
Patients who took 250 mg of oral magnesium after anorectal surgery ended up using more narcotic pain medication than those who took the NSAID ketorolac, a difference the researchers called statistically significant. While magnesium matched ketorolac's pain relief after the first few days, the higher narcotic consumption in the magnesium group is a surprising and cautionary result that needs replication before drawing firm conclusions.
