Esomeprazole and Magnesium Glycinate, a caution.
Long-term esomeprazole use can cause hypomagnesemia, sometimes severe enough to trigger tetany, seizures, or arrhythmia. The FDA has issued a class warning for PPIs after multiple case series, and meta-analyses confirm a near-doubling of hypomagnesemia risk in chronic users. Supplemental magnesium often only partially corrects the deficit while the PPI is continued.

Caution
What is happening. Long-term esomeprazole use can cause hypomagnesemia, sometimes severe enough to trigger tetany, seizures, or arrhythmia. The FDA has issued a class warning for PPIs after multiple case series, and meta-analyses confirm a near-doubling of hypomagnesemia risk in chronic users. Supplemental magnesium often only partially corrects the deficit while the PPI is continued.
Mechanism. Prolonged acid suppression appears to impair active magnesium uptake in the small intestine via TRPM6/TRPM7 channels, which depend on luminal proton gradients. The defect reverses within days of stopping the PPI and recurs on rechallenge.
Recommendation. If you take esomeprazole for more than a year, ask your prescriber to check serum magnesium periodically. If levels are low, a daily magnesium glycinate supplement is reasonable, but persistent or symptomatic hypomagnesemia usually requires stopping the PPI to fully resolve.
