Adverse Effects
Adverse effects of calcium gluconate include syncope, bradycardia, and paresthesias.;One of the most concerning adverse effects of calcium gluconate is extravasation from intravenous sites. Calcium can induce tissue necrosis through calcium-induced vasoconstriction of capillaries and intracellular fluid retention, leading to deep tissue damage and late-onset calcifications. Stop the infusion for extravasation injury treatment and gently aspirate the extravasated fluid.;In early or acute calcium extravasation, a hyaluronidase antidote is an option in addition to cold, dry compresses and extremity elevation. Between 1 and 1.7 mL of hyaluronidase may be given intradermally into the border of the extravasated area as 5 separate injections. Injection into the catheter that caused the infiltration is also appropriate.
Toxicity Summary
Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org
Calcium gluconate is a vesicant that can cause extravasation injury leading to tissue necrosis; see “Adverse Effects” above.;Systemic toxicity due to calcium gluconate is identical to the systemic effects of hypercalcemia. Hypercalcemia typically manifests as nonspecific symptoms such as fatigue, muscle weakness, anorexia, and polydipsia. Hypercalcemia causes ECG changes, including short QT interval, prolonged PR interval, widened QRS, T wave abnormalities, and variable degrees of heart block.
Ecotoxicity Excerpts
/AQUATIC SPECIES/ Daphnia are highly sensitive to sodium metabolism disruption caused by aquatic acidification and ionoregulatory toxicants, due to their finely balanced ion homeostasis. Nine different water chemistries of varying pH (4, 6 and 8) and calcium concentration (0, 500 and 1000 umol/L) were used to delineate the mechanism of sodium influx in Daphnia magna. Lowering water pH severely inhibited sodium influx when calcium concentration was high, but transport kinetic analysis revealed a stimulated sodium influx capacity (J(max)) when calcium was absent. At low pH increasing water calcium levels decreased J(max) and raised K(m) (decreased sodium influx affinity), while at high pH the opposite pattern was observed (elevated J(max) and reduced K(m)). These effects on sodium influx were mirrored by changes in whole body sodium levels. Further examination of the effect of calcium on sodium influx showed a severe inhibition of sodium uptake by 100 umol/L calcium gluconate at both low (50 umol/L) and high (1000 umol/L)) sodium concentrations. At high sodium concentrations, stimulated sodium influx was noted with elevated calcium levels. These results, in addition to data showing amiloride inhibition of sodium influx (K(i)=180 umol/L), suggest a mechanism of sodium influx in Daphnia magna that involves the electrogenic 2Na(+)/1H(+) exchanger.
Human Toxicity Excerpts
/SIGNS AND SYMPTOMS/ Potential toxicity in neonates: Bradycardia, sloughing and calcification with IV infiltration; potentiates digitalis effect
/CASE REPORTS/ A 43-year-old man developed septic shock and acute lung injury after surgery to drain an ischiorectal abscess. In the intensive care unit he initially improved but developed severe hypoxaemia, right ventricular failure and pulmonary hypertension 90 min after receiving intravenous calcium gluconate and potassium phosphate, best explained by the formation of a calcium-phosphate precipitant that resulted in aggregate anaphylaxis. His rapid deterioration and lack of response to conventional therapies necessitated support with extracorporeal membrane oxygenation that was life saving. This adverse event has altered local practice regarding calcium and phosphate replacement and has implications for all intensive care units.
Non-Human Toxicity Excerpts

Antidote and Emergency Treatment
A serum calcium concentration exceeding 2.6 mmol per liter (10.5 mg per 100 mL) is considered a hypercalcemic condition. Withholding additional administration of calcium and any other medications that may cause hypercalcemia usually resolves mild hypercalcemia in asymptomatic patients, when patient renal function is adequate. /Calcium supplements/
When serum calcium concentration are greater than 2.9 mmol per liter (12 mg per 100 mL), immediate measures may be required with possible use of the following: Hydrating with intravenous 0.9% sodium chloride injection. Forcing diuresis with furosemide or ethacrynic acid may be used to rapidly increase calcium and sodium excretion when saline overload occurs. Monitoring of potassium and magnesium serum concentrations and starting replacement early to prevent complications of therapy. ECG monitoring and the possible use of beta-adrenergic blocking agents to protect the heart against serious arrhythmias. Possibly including hemodialysis, calcitonin, and adrenocorticoids in the treatment. Determining serum calcium concentration at frequent intervals to guide therapy adjustments. /Calcium supplements/
Topical application of calcium gluconate gel is the first-line emergency department treatment for Hydrofluoric acid burns after irrigation.
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... .

Pharmacodynamics
Calcium Gluconate is the gluconate salt of calcium. An element or mineral necessary for normal nerve, muscle, and cardiac function, calcium as the gluconate salt helps to maintain calcium balance and prevent bone loss when taken orally. This agent may also be chemopreventive for colon and other cancers.
Mechanism of Action
Calcium is essential for the functional integrity of the nervous, muscular, and skeletal systems. It plays a role in normal cardiac function, renal function, respiration, blood coagulation, and cell membrane and capillary permeability. Also, calcium helps to regulate the release and storage of neurotransmitters and hormones, the uptake and binding of amino acids, absorption of vitamin B 12, and gastrin secretion. The major fraction (99%) of calcium is in the skeletal structure primarily as hydroxyapatite, Ca 10(PO 4) 6(OH) 2; small amounts of calcium carbonate and amorphous calcium phosphates are also present. The calcium of bone is in a constant exchange with the calcium of plasma. Since the metabolic functions of calcium are essential for life, when there is a disturbance in the calcium balance because of dietary deficiency or other causes, the stores of calcium in bone may be depleted to fill the body's more acute needs. Therefore, on a chronic basis, normal mineralization of bone depends on adequate amounts of total body calcium.
FDA Pharmacological Classification

Cations, Divalent [CS]; Calcium [CS]; Phosphate Chelating Activity [MoA]; Increased Coagulation Factor Activity [PE]; Phosphate Binder [EPC]; Blood Coagulation Factor [EPC]
Absorption, Distribution and Excretion
Approximately one-fifth to one-third of orally administered calcium is absorbed in the small intestine, depending on presence of vitamin D metabolites, pH in lumen, and on dietary factors, such as calcium binding to fiber or phytates. Calcium absorption is increased when a calcium deficiency is present or when a patient is on a low-calcium diet. In patients with achlorhydria or hypochlorhydria, calcium absorption, especially with the carbonate salt, may be reduced.
Renal (20%) - The amount excreted in the urine varies with degree of calcium absorption and whether there is excessive bone loss or failure of renal conservation. Fecal (80%) - Consists mainly of nonabsorbed calcium, with only a small amount of endogenous fecal calcium excreted.
