Calcium chloride

Updated 2 Feb 2023 | Calcium supplements

Presentation

Sterile aqueous solution of calcium chloride 100mg/ml (10%) for slow intravenous injection (infusion) or intracardiac use.

Each 10 ml pre-filled syringe provides 1g of calcium chloride dihydrate equivalent to 273mg of calcium (6.8mmol of calcium) .

Drugs List

  • calcium chloride 1g/10ml (10%; 6.8mmol/10ml) injection
  • Therapeutic Indications

    Uses

    In cardiopulmonary resuscitation with co-existing hyperkalaemia or hypocalcaemia or calcium channel block activity.

    Hypocalcaemia
    Calcium deficiency states
    Hypocalcaemic tetany (immediate treatment) with other therapy instituted as appropriate.

    As adjunctive therapy in the management of hyperkalaemia, with ECG monitoring.
    As adjunctive therapy in the management of overdosage of magnesium sulfate.

    Dosage

    Adults

    In cardiopulmonary resuscitation: a single dose of 10ml (10%) has been used, however, the use of calcium is generally not recommended unless there is hypokalaemia, hypocalcaemia or the patient is known to be on calcium antagonists. Specialist guidelines should be consulted.

    Hyperkalaemic ECG disturbances of cardiac function:
    Adjust dose by constant monitoring of ECG changes during administration.

    Intracardiac use:
    In cardiac resuscitation, injection may be made into the ventricular cavity. It must not be injected into the myocardium. Dose 2-4ml (200-400mg)

    In acute hypocalcaemia:
    A typical dose is 2.25 - 4.5mmol (3-10ml of the 10% solution) repeated at intervals.
    Alternatively 500mg-1g (5-10ml) at intervals of one to three days, depending upon response.

    Magnesium intoxication:
    5ml (500mg) administered promptly. Observe patient for signs of recovery before giving further doses.

    Elderly

    Children

    Not all brands are licensed for use in children.

    In cardiopulmonary resuscitation: calcium chloride has been used, however, the use of calcium is generally not recommended unless there is hypokalaemia, hypocalcaemia or the patient is known to be on calcium antagonists. Specialist guidelines should be consulted.

    Intracardiac use:
    In cardiac resuscitation, injection may be made into the ventricular cavity. It must not be injected into the myocardium. Dose 0.2ml/kg bodyweight.

    In acute hypocalcaemia:
    The usual dose is 0.2ml/kg of the 10% solution (maximum 1-10ml/day).

    Patients with Renal Impairment

    Use with caution in renal impairment, due to the increased risk of hypercalcaemia and renal calculi.

    Administration

    For slow intravenous and intracardiac use only.

    The IV injection should be given at a rate not exceeding 1ml/minute.

    Inject slowly through a small needle into a large vein to minimise venous irritation and avoid undesirable effects. Calcium chloride is considered to be the most irritant of the injectable calcium salts. Care should be taken to avoid extravasation.

    Other routes are contraindicated due to the risk of necrosis.

    Infant injections should not be given thorough the scalp.

    Incompatibilities

    Calcium salts are incompatible with a wide range of drugs. Complexes may form resulting in the formation of a precipitate. Generally the mixing of calcium with carbonates, citrates, oxidising agents, phosphates, sulfates, tartrates, tetracyclines or parenteral mixtures including total parenteral nutrition should be avoided.

    In patients of any age ceftriaxone must not be mixed or administered simultaneously with any calcium-containing IV solutions, even via different infusion lines or at different infusion sites. However for patients older than 28 days ceftriaxone and calcium-containing solutions may be administer sequentially one after another if infusion lines at different sites are used.

    Contraindications

    Patients receiving cardiac glycosides
    Hypercalcaemia
    Hypercalciuria
    Hypervitaminosis D
    Renal calculi
    History of renal calculi

    Patients with respiratory acidosis or respiratory failure - due to it's acidifying nature.

    Ventricular fibrillation (when employed in cardiac resuscitation).

    For slow intravenous use or intracardiac use only - other routes are contraindicated due to the risk of necrosis.

    Precautions and Warnings

    Renal impairment (see 'Dosage; Renal impairment' section)

    Sarcoidosis

    Cardiac disease

    A moderate fall in blood pressure due to vasodilatation may accompany the injection.

    Not suitable for the treatment of hypocalcaemia caused by renal impairment (due to calcium chloride's acidifying nature).

    Calcium chloride is considered to be the most irritant of the injectable calcium salts. Severe tissue necrosis and sloughing may occur. Care should be taken to avoid extravasation or accidental injection into perivascular tissues.

    Calcium chloride should not be give to infants orally as it can cause irritation to the gastrointestinal tract. Infant injections should not be given thorough the scalp.

    Ceftriaxone is contraindicated in premature newborns up to a corrected age of 41 weeks and full-term newborns if they require IV calcium treatment, because of the risk of precipitation of ceftriaxone-calcium complexes in lungs and kidneys. In patients of any age do not mix or administer both together, even via different infusion lines or at a different infusion sites. However, for patients older than 28 days ceftriaxone and calcium-containing solutions may be administer sequentially one after another if infusion lines at different sites are used.

    Monitoring of calcium and serum electrolytes levels is necessary following intravenous administration of calcium.

    Pregnancy ( see 'Pregnancy' section)

    Breastfeeding ( see 'Lactation' section)

    Pregnancy and Lactation

    Pregnancy

    Evaluate risk / benefit of treatment in pregnancy.

    There are no studies on the effects of calcium chloride on pregnant women. No problems have been documented. However calcium crosses the placenta and absorption of calcium is increased during pregnancy.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14-17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).

    Lactation

    Use with caution in lactation

    Calcium is excreted in breast milk, but there are no data on the effects, if any, on the infant.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
