Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction you experienced, including any symptoms that occurred.
If you have elevated calcium levels in your blood.
If you are currently taking ceftriaxone or digoxin.
Please note that this is not an exhaustive list of all potential interactions with this medication. To ensure your safety, it is crucial to discuss all of your:
Prescription and over-the-counter (OTC) medications
Natural products
Vitamins
* Health problems
with your doctor and pharmacist. This will help determine whether it is safe to take this medication in conjunction with your other treatments. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
This medication may contain aluminum, which can pose a risk of aluminum toxicity if taken for an extended period. This risk is particularly higher if you have kidney problems or if you are a premature infant. It is vital to discuss this potential risk with your doctor.
If you are pregnant, planning to become pregnant, or breastfeeding, you must consult your doctor to weigh the benefits and risks of taking this medication, both for you and your baby.
Overdose Information
Overdose Symptoms:
- Severe hypercalcemia (calcium levels too high)
- Nausea, vomiting, constipation
- Muscle weakness, lethargy, confusion
- Polyuria, polydipsia
- Bradycardia (slow heart rate)
- Hypotension (low blood pressure)
- Cardiac arrhythmias (irregular heartbeats)
- Coma
- Cardiac arrest
What to Do:
Immediate medical attention is required. Treatment involves stopping calcium administration, IV fluids (saline), loop diuretics (e.g., furosemide) to promote calcium excretion, and potentially calcitonin or bisphosphonates in severe cases. Dialysis may be necessary. Call 1-800-222-1222 (Poison Control) for further guidance.
Drug Interactions
Contraindicated Interactions
- Ceftriaxone (in neonates, due to risk of precipitation in lungs and kidneys)
- IV phosphate solutions (risk of calcium phosphate precipitation)
- Bicarbonate solutions (risk of calcium carbonate precipitation)
Major Interactions
- Digoxin (increased risk of cardiac arrhythmias, especially with rapid IV calcium administration or hypercalcemia)
- Calcium channel blockers (calcium may antagonize the effects of CCBs, requiring higher doses of CCBs or reducing their efficacy)
Moderate Interactions
- Thiazide diuretics (may decrease calcium excretion, leading to hypercalcemia)
- Corticosteroids (may decrease intestinal absorption of calcium)
- Tetracyclines and fluoroquinolones (oral calcium can chelate these antibiotics, reducing absorption; not relevant for IV calcium gluconate but important if oral calcium is also given)
- Iron supplements (oral calcium can interfere with iron absorption; not relevant for IV calcium gluconate)
Monitoring
Baseline Monitoring
Rationale: To establish baseline calcium status and guide initial dosing.
Timing: Prior to administration.
Rationale: To assess overall electrolyte balance, especially in conditions like hyperkalemia or hypomagnesemia, and to identify potential for precipitation.
Timing: Prior to administration.
Rationale: To assess kidney's ability to excrete calcium and guide dosing in renal impairment.
Timing: Prior to administration.
Rationale: To assess cardiac rhythm and identify pre-existing abnormalities, especially important in hyperkalemia or patients on digoxin.
Timing: Prior to administration, especially for rapid infusions or cardiac indications.
Routine Monitoring
Frequency: Every 1-6 hours initially, then daily or as clinically indicated, depending on patient stability and indication.
Target: Normal range (e.g., total calcium 8.5-10.5 mg/dL, ionized calcium 1.12-1.32 mmol/L), or target based on clinical indication.
Action Threshold: Hypocalcemia (below target) or Hypercalcemia (above target); adjust infusion rate or discontinue.
Frequency: Continuous during rapid infusion, then periodically as clinically indicated, especially in patients with cardiac disease or on digoxin.
Target: Normal sinus rhythm, absence of arrhythmias or conduction abnormalities.
Action Threshold: Development of bradycardia, arrhythmias, or QT interval changes; slow infusion, discontinue, or administer antidote if severe.
Frequency: Every 15-30 minutes during infusion, then every 1-4 hours.
Target: Within patient's normal range.
Action Threshold: Significant bradycardia, hypotension, or hypertension; adjust infusion rate or investigate cause.
Frequency: Continuously during infusion.
Target: No signs of swelling, pain, redness, or blanching.
Action Threshold: Signs of extravasation; stop infusion immediately, elevate limb, consider hyaluronidase.
Symptom Monitoring
- Signs of hypercalcemia: Nausea, vomiting, constipation, abdominal pain, muscle weakness, lethargy, confusion, polyuria, polydipsia, cardiac arrhythmias.
- Signs of hypocalcemia (if treatment is insufficient): Tetany, muscle cramps, paresthesias, seizures, prolonged QT interval.
- Signs of extravasation: Pain, swelling, redness, blanching at the injection site.
Special Patient Groups
Pregnancy
Calcium gluconate is classified as Pregnancy Category C. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Calcium requirements increase during pregnancy, and calcium is essential for fetal skeletal development. However, excessive calcium administration can lead to hypercalcemia in the mother and potentially affect the fetus.
Trimester-Specific Risks:
Lactation
Calcium is a normal component of breast milk. While calcium gluconate is generally considered compatible with breastfeeding, caution is advised. Monitor the infant for any signs of adverse effects, though systemic absorption by the infant from breast milk is unlikely to cause issues.
Pediatric Use
Dosing is weight-based and requires careful calculation. Neonates and infants are particularly susceptible to rapid changes in calcium levels and extravasation. Close monitoring of serum calcium, heart rate, and IV site is essential. Avoid rapid IV push in neonates and infants due to risk of bradycardia and cardiac arrest.
Geriatric Use
Elderly patients may have age-related decreases in renal function, increasing the risk of hypercalcemia. They may also be more susceptible to cardiac arrhythmias. Use with caution and monitor serum calcium and ECG closely. Start with lower doses and titrate carefully.
Clinical Information
Clinical Pearls
- Calcium gluconate 10% solution contains 93 mg (4.65 mEq) of elemental calcium per 10 mL vial. This is less elemental calcium than calcium chloride (which contains 272 mg elemental calcium per 10 mL of 10% solution), making it less irritating to veins.
- Administer slowly via IV infusion to avoid bradycardia, hypotension, and cardiac arrhythmias. Rapid IV push is generally discouraged, especially in patients on digoxin or with cardiac disease.
- Always dilute calcium gluconate if administering via central line, and ensure proper mixing if adding to IV fluids.
- Do NOT mix with bicarbonate or phosphate solutions in the same IV line due to precipitation risk.
- Monitor ECG continuously during rapid infusions, especially for hyperkalemia or in patients on digoxin.
- Extravasation can cause severe tissue necrosis and calcification. Ensure proper IV access and monitor the site closely. If extravasation occurs, stop infusion immediately, aspirate residual drug, and consider local hyaluronidase injection.
- Correct hypomagnesemia if present, as magnesium is essential for parathyroid hormone function and calcium homeostasis.
Alternative Therapies
- Calcium chloride (provides more elemental calcium per gram, but is more irritating to veins and should be administered via central line if possible).
- Oral calcium supplements (for chronic hypocalcemia, not acute emergencies).
- Vitamin D supplementation (for chronic calcium deficiency related to vitamin D deficiency).
