Magnesium
In a case report, a man developed severe magnesium deficiency after long-term treatment with a proton pump inhibitor (pantoprazole or lansoprazole).1 Severe magnesium deficiency as a result of the use of proton pump inhibitors appears to be rare among people who have no other risk factors for magnesium deficiency. However, in a study of hospitalized patients, the prevalence of low serum magnesium levels was significantly greater among users of proton pump inhibitors than among nonusers (23% vs. 11%).2 People taking proton pump inhibitors (PPIs) should ask their doctor whether to take a magnesium supplement or whether to have their magnesium levels monitored.3
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Potential Negative Interaction
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
