Can teriparatide injection cause hypercalcemia?

Teriparatide injection may cause hypercalcemia, which is a common adverse reaction. Teriparatide promotes bone formation and calcium release by mimicking the effects of parathyroid hormone. While this effect has a positive impact on the treatment of osteoporosis, it may also lead to increased concentrations of calcium in the blood. The occurrence of hypercalcemia is usually temporary, but if the calcium concentration is too high, it will have certain negative effects on the body.

Symptoms of hypercalcemia may include nausea, vomiting, loss of appetite, thirst, constipation, muscle weakness, fatigue, and frequent need to urinate. These symptoms may appear as mild symptoms or may be severe and affect the patient's quality of life. The effects of hypercalcemia on the kidneys are also of concern, as it may lead to the formation of kidney stones or other kidney function problems. Therefore, patients should regularly monitor blood calcium levels when using teriparatide injection, especially at the beginning of treatment and after drug dose adjustment.

To reduce the risk of hypercalcemia, doctors usually perform regular blood calcium testing during treatment. Once an increase in blood calcium is detected, the doctor may adjust the dose of teriparatide or suspend treatment. In addition, patients should avoid taking teriparatide with other drugs that may increase blood calcium levels, especially calcium-containing supplements or certain steroid drugs. Concomitant use of these drugs may increase the risk of hypercalcemia.

Although hypercalcemia is a possible side effect, not all patients taking teriparatide will develop this problem. For most patients, blood calcium levels remain within normal limits and no serious side effects occur. However, in order to ensure the safety of treatment, patients should use teriparatide under the guidance of a doctor and undergo regular examinations to detect and respond to the possible risk of hypercalcemia early.
