What the labels, MedlinePlus and one trial state
- Hydrochlorothiazide label: thiazides increase magnesium loss in urine and may cause low magnesium.[1]
- Lasix label: furosemide may lower serum magnesium.[2]
- Omeprazole label: low magnesium has been reported rarely after at least three months of PPI use, mostly after a year, and most patients needed magnesium replacement and to stop the PPI.[3]
- MedlinePlus: side effects from high magnesium intake are uncommon except with significantly reduced kidney function; excess usually comes from supplements or magnesium laxatives.[4]
- In adults with low magnesium and insulin resistance, magnesium chloride 2.5 g daily lowered mean HOMA-IR from 4.6 to 2.6 over 3 months; placebo did not.[5]

Questions for your clinician or pharmacist
