Indications & Uses

Calcitonin is used to treat active Paget's disease when other treatments haven't worked or aren't suitable for the patient, as well as to treat hypercalcaemia (high calcium levels in the blood).

Pharmacology

Calcitonin is a polypeptide hormone made naturally by the ultimobranchial gland in non-mammalian vertebrates, and by the parafollicular cells of the thyroid gland in mammals. It works by inhibiting osteoclast-driven bone resorption, which lowers the overall rate of bone turnover. It also acts on the kidneys, reducing tubular reabsorption and increasing the renal excretion of calcium, chloride, sodium, magnesium, potassium and phosphate.

Cautions & Contraindications

Warnings & Precautions

Skin testing is recommended before starting treatment. Use with caution in heart failure or kidney impairment. Not recommended in pregnancy, breastfeeding, or children.

Contraindications

Hypersensitivity to the drug, and low blood calcium levels.

Pregnancy & Breastfeeding

Pregnancy Category C. This means either animal studies have shown some risk to the developing baby (such as birth defects or fetal loss), but there are no well-controlled studies in pregnant women, or no studies have been done in either women or animals. Because of this uncertainty, salmon calcitonin should be used during pregnancy only if the potential benefit to the mother is judged to outweigh the possible risk to the unborn child.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

Renal Impairment: Salmon Calcitonin needs a dosage adjustment.

Overdose

An overdose of Salmon Calcitonin can cause flushing, nausea, vomiting and dizziness. Treatment is symptomatic and supportive.
