Calcium gluconate is available under several brand names and formulations. Below are some of the most commonly used medications in this drug class:
- Calcium Gluconate 10% (Calcium Gluconate)
- Calcijex (Calcium Gluconate)
- K-Cin (Calcium Gluconate)
- NeoCalglucon (Calcium Gluconate)
- PediaCal (Calcium Gluconate)
The generic name of a medication refers to its active ingredient, which is listed in parentheses. While generic names are standardized and universally recognized, brand names can vary depending on the manufacturer.
How Does Calcium Gluconate Work? (Mechanism of Action)
Calcium gluconate works by increasing calcium levels in the bloodstream, which supports a variety of essential bodily functions. Calcium is vital for muscle contractions, nerve communication, blood clotting, and maintaining healthy bones. When administered, calcium gluconate provides a bioavailable form of calcium that the body can absorb and use efficiently. Although all medications in this class share the same active ingredient, differences in formulation or concentration may affect how they are administered, whether orally or intravenously.
Calcium Gluconate Benefits
Calcium gluconate is primarily used to treat hypocalcemia, a condition marked by insufficient calcium levels in the blood. It is also employed in emergency situations, such as cardiac arrest caused by hyperkalemia (elevated potassium levels) or magnesium toxicity. This medication is often preferred over other calcium supplements in specific cases due to its tolerability and the option for intravenous administration, which allows for rapid action.

Potential Side Effects of Calcium Gluconate
When used as directed, calcium gluconate is generally well-tolerated. However, like all medications, it may cause side effects, which can range from mild to severe. Below is a detailed overview of potential side effects, categorized by their frequency. If you experience any side effects, contact your healthcare provider promptly. Severe side effects require immediate medical attention.
Common Side Effects (≥1%)
- Injection site reactions (up to 10%): Intravenous administration may lead to redness, swelling, or discomfort at the injection site, particularly in individuals with sensitive skin or those receiving repeated doses.
- Hypotension (low blood pressure) (2-5%): Rapid IV administration can cause a drop in blood pressure, which may result in symptoms such as dizziness, lightheadedness, or fainting.
- Nausea or vomiting (1-3%): Some individuals may experience nausea or an upset stomach, especially when taking the medication orally or in higher doses.
Less Common Side Effects (<1%)
Although less frequent, the following side effects are still possible:
- Constipation
- Excessive thirst
- Dry mouth
- Increased urination
- Metallic taste
- Tingling sensations
- Flushing
- Headache
Severe Side Effects
Severe side effects are rare but can occur and require immediate medical attention. These include:
- Hypercalcemia (high calcium levels): Symptoms may include confusion, fatigue, irregular heartbeat, muscle weakness, and kidney problems. This is more likely to occur in individuals receiving high doses or those with pre-existing kidney conditions.
- Cardiac arrhythmias: Rapid or irregular heartbeats may develop, particularly if calcium gluconate is administered too quickly via IV.
- Tissue necrosis: Leakage of calcium gluconate from the vein during IV administration can result in severe tissue damage.
If you experience any severe side effects, stop using the medication and seek emergency medical care immediately. Always share your medical history and current medications with your healthcare provider before starting calcium gluconate. Our telemedicine providers are available to help determine whether this medication is appropriate for your needs.
Drug-to-Drug Interactions with Calcium Gluconate
Calcium gluconate can interact with a variety of medications, potentially affecting their effectiveness or increasing the likelihood of side effects. Being aware of these interactions is crucial for ensuring safe and effective use. Below are some of the most common drug-to-drug interactions associated with calcium gluconate:
Digoxin: When calcium gluconate is combined with digoxin, particularly when administered intravenously (IV), it may increase the risk of cardiac arrhythmias. This interaction requires careful monitoring by a healthcare provider.
Calcium Channel Blockers: Calcium gluconate can diminish the effectiveness of calcium channel blockers, such as amlodipine or verapamil, which are commonly prescribed for managing high blood pressure and certain heart conditions.
Bisphosphonates: Calcium can interfere with the absorption of bisphosphonates, such as alendronate, which are used to treat osteoporosis. To reduce this interaction, it is recommended to take bisphosphonates at least two hours before or after calcium gluconate.
Tetracycline and Fluoroquinolone Antibiotics: Calcium binds to these antibiotics in the stomach, which can reduce their absorption and effectiveness. To avoid this interaction, take these antibiotics at least two hours apart from calcium gluconate.
Thiazide Diuretics: Thiazide diuretics can increase calcium levels in the blood, raising the risk of hypercalcemia when used alongside calcium gluconate. This combination should be monitored closely by a healthcare provider.
To minimize the risk of potential interactions, always inform your healthcare provider about all medications, supplements, and over-the-counter products you are currently taking. Our telemedicine providers are available to review your medication list and help ensure the safe use of calcium gluconate.
