Historical source: not automatically current. Review current official labeling and separately attributed additions before use.

Usual dosing source scope

The original usual-dosing section links to a separate magnesium-supplement guide rather than supplying a specific regimen. No numeric replacement dose is inferred from that link.

Renal Dosing

Magnesium is eliminated by the kidneys. Severe impairment (CrCl below 30 mL/min) requires lower doses and frequent serum-level monitoring in the GlobalRPh discussion. Use caution when replacing magnesium in any degree of renal insufficiency.

GlobalRPh physiological comments

Magnesium balance is regulated primarily by the kidneys; intake itself is not regulated. Dietary intake is approximately 20-30 mEq/day, with net absorption around 7 mEq/day. Normal urinary excretion equals net intake; during deficiency minimum urinary excretion is approximately 2 mEq/day.

About 30% of filtered magnesium is reabsorbed proximally and 65% in the thick ascending limb of Henle. Reabsorption is saturable: increased intake produces a proportionate increase in excretion. Consequently, hypermagnesemia is difficult to produce with normal renal function.

Hemodialysis

The source refers back to its preceding comments; no separate dialysis replacement regimen is supplied.

Import versus clinical validation
Source-section locators identify where retained content came from. A source-section identifier does not assert that every numeric statement has been independently corroborated. The local text hash is not a hash of original HTML, an FDA PDF or SPL XML.

The original individual GlobalRPh pages commonly cite NIH/NLM DailyMed and instruct readers to review the applicable package insert for updates. That historical reference is preserved as context; it is not counted as an independently retrieved current label.
