'"`UNIQ--vote-00000016-QINU`"' Bicarbonate is not benign: high-volume use produces hypernatremia, metabolic alkalosis, hypokalemia, and (in arrest) paradoxical intracellular acidosis'"`UNIQ--ref-00000017-QINU`"'. (1) · '"`UNIQ--vote-00001302-QINU`"' Renally cleared; accumulation in advanced CKD can produce neuromuscular and cardiac depression. Hypomagnesemia frequently co-exists with hypokalemia and is often the reason refractory potassium loss does not correct until magnesium is repleted. (1)

IV: 1 mEq/kg bolus in arrest indication, then titrated to ABG and clinical status; PO: 325-2000 mg up to QID as antacid (1) · Replacement oxide 400-800 mg/d in divided doses (high diarrhea rate); citrate 200-400 mg/d (better tolerated, better absorbed); IV sulfate 1-2 g over 5-60 minutes for hypomagnesemia or torsades; eclampsia 4-6 g IV loading then 1-2 g/h (1)

Indication-specific; renal clearance limits tolerable cumulative dosing (1) · No fixed maximum; titrated to pH and bicarbonate level; chronic high oral doses cause metabolic alkalosis and volume overload (1)
