Calcium gluconate is a mineral supplement.



It is the form of calcium most widely used in the treatment of hypocalcemia. This form of calcium is superior to calcium lactate, but it only contains 0.93%(930mg/100ml) calcium. Calcium gluconate is a salt of calcium and gluconic acid.

Magnesium sulfate overdose

It is also used to counteract an overdose of magnesium sulfate,[1] which is often administered to pregnant women in order to prophylactically prevent seizures (as in patient experiencing preeclampsia). Magnesium sulfate is also given to pregnant women who are experiencing premature labor in order to slow or stop their contractions. Excess magnesium sulfate results in magnesium sulfate toxicity, which results in both respiratory depression and a loss of deep tendon reflexes (hyporeflexia). Calcium gluconate is the antidote for magnesium sulfate toxicity.

Treatment of HF burns

Gel preparations of calcium gluconate are used to treat hydrofluoric acid burns.[2][3]

Use in Hyperkalemia

Calcium gluconate is also used as a cardioprotective agent in hyperkalemia. Though it does not have an effect on potassium levels in the blood, it reduces the excitability of cardiomyocytes thus lowering the likelihood of developing cardiac arrhythmias.

Side Effects

Calcium gluconate side effects include nausea, constipation, stomach upset. Extravasation of calcium gluconate can lead to cellulitis. It is also reported that this form of calcium increases renal plasma flow, diuresis, natriuresis, [4] [5] glomerular filtration rate,[6] and prostaglandin E2 and F1-alpha levels.[7]

Rapid intravenous injections of calcium gluconate may cause vasodilation, cardiac arrhythmias, decreased blood pressure, and bradycardia. Intramuscular injections may lead to local necrosis and abscess formation. [8]
