4.4. Special Warnings and Precautions for Use

Injections of calcium chloride are extremely irritant, and so dilution is recommended. Only the intravenous route may be employed. Patients treated for hypocalcaemia should be adequately monitored, including serum calcium. It should be given with caution to patients with cardiac disease or sarcoidosis.

4.5. Interactions with other Medicaments and other forms of Interaction

With digitalis or potassium there is an increased risk of arrhythmias. Thiazide diuretics can reduce the excretion of calcium leading to elevated plasma levels. The effect of administered magnesium may be neutralised by calcium. The absorption of tetracyclines is reduced by calcium.

4.6. Pregnancy and Lactation

There is no evidence of safety of the drug in human pregnancy, but it has been in use for many years without ill consequence. If it is needed in pregnancy, the use of this drug is acceptable.

Parenteral calcium can cause dizziness and drowsiness, if affected, patients should not drive or operate machinery.

4.9. Overdose

Symptoms:

The early signs of overdose include severe constipation, drowsiness, continuous headache, loss of appetite, metallic taste, dry mouth, tiredness and weakness. Later signs include confusion, hypertension, increased light sensitivity, thirst, muscle or bone pain, nausea, vomiting and polyuria.

Treatment:

A diuretic such as bumetanide, ethacrynic acid or frusemide will assist in the excretion of excessive calcium, but in very severe cases, EDTA may be necessary.

Pharmacological Properties

5.1. Pharmacodynamic Properties

Calcium is essential to the function of the nervous, muscular and skeletal systems. It also plays a part in cardiac function, renal function, respiration and blood coagulation.

5.2. Pharmacokinetic Properties

Calcium is distributed throughout the body, but is in large amounts in the skeleton as the hydroxyapatite complex.Ca2+ is 45% plasma protein bound. Elimination is mainly faecal, with small amounts excreted in the urine.

None stated.
