| Name | Calcium Gluconate |
| Uses | Electrolyte supplement used to support nerve conduction, muscle contraction, bone health, and calcium replenishment. In wellness settings, it may be included in IV formulations for patients needing calcium support, particularly in those with dietary deficiencies or increased demands (e.g., athletes). |
| Route Of Administration | Intravenous (IV) |
| Frequency Of Use | Administered as needed based on clinical assessment. In wellness protocols, typically given once weekly if indicated, with re-evaluation after 4 to 6 weeks. |
| Concentration(s) | Common concentration: 100 mg/mL (calcium gluconate, providing approximately 9.3 mg elemental calcium per mL). |
| Maximum Dosage (Day, Wk) (g/mL)/mL | Maximum dose per infusion: 2 g (20 mL of 100 mg/mL solution). Maximum weekly dose: 4 g (40 mL). Higher doses are not recommended for elective wellness patients due to risk of hypercalcemia. |
| Contraindications | Hypercalcemia. Severe renal impairment. Ventricular fibrillation. Known hypersensitivity to calcium gluconate or any formulation component. Digitalis toxicity. Use caution in patients with sarcoidosis or calcium metabolism disorders. |
| Possible Side Effects | Flushing, nausea, metallic taste, or warmth during infusion. Injection site irritation if extravasation occurs. Hypercalcemia symptoms (confusion, muscle weakness, constipation) with excessive use. Rare: allergic reaction (rash, itching, anaphylaxis). |
| Compatibility With Other Drugs | Incompatible with phosphate-containing solutions (risk of precipitation). May precipitate with magnesium if not properly diluted. Always confirm compatibility before mixing with vitamins, minerals, or amino acids. |
| Allergies | True allergy to calcium gluconate is rare. Reactions are more often related to preservatives in compounded formulations. |
| Administration Time | Typical infusion time: 30 to 60 minutes for doses up to 2 g. Slower infusion improves tolerability and reduces risk of flushing or discomfort. |
| IV Dosing | For general calcium support: 1 g to 2 g IV once weekly, adjusted based on dietary intake and clinical assessment. |
| IM/Push | Slow IV push is possible for small doses (e.g., 1 g over 5 to 10 minutes). IM administration is not recommended due to risk of local irritation and tissue necrosis. |
| What To Do If Adverse Reaction Occurs | 1. Stop the infusion immediately if a reaction occurs. 2. Assess vital signs (blood pressure, heart rate, oxygen saturation). 3. If flushing, nausea, or metallic taste occurs, slow the infusion rate and provide supportive care. 4. If extravasation occurs, stop the infusion and manage the site with local care (cold compress, elevation). 5. For allergic reactions (rash, itching, shortness of breath), administer antihistamines and consider epinephrine if severe. 6. If hypercalcemia symptoms develop (confusion, muscle weakness, constipation), check serum calcium and provide hydration and supportive care. 7. If symptoms persist or worsen, arrange for emergency transfer to a higher level of care (call 911 if necessary). |
