You’re asking about the possibility of high blood calcium (hypercalcemia) when using Gemcal nasal spray and Shelcal HD together.

• Medications involved:

  • Gemcal nasal spray contains calcitonin, a hormone that helps lower blood calcium levels by reducing calcium release from bones.
  • Shelcal HD contains calcium and cholecalciferol (vitamin D3), which increase calcium levels by promoting calcium absorption from the gut.

• How they affect calcium levels:
  Calcitonin generally works to decrease calcium in the blood, while calcium supplements with vitamin D increase calcium levels.

• Risk of hypercalcemia:
  Using these together usually balances out because calcitonin lowers calcium, and Shelcal HD raises it. However, if calcium intake is very high or if there are underlying conditions affecting calcium metabolism, there could be a risk of elevated calcium levels.

• Advice:
  It’s important to monitor calcium levels through blood tests if you are on these medications simultaneously. Watch for symptoms of hypercalcemia such as nausea, vomiting, confusion, or excessive thirst. Always follow your doctor’s guidance on dosage and report any unusual symptoms promptly.

Please consult an endocrinologist or your prescribing doctor to ensure safe use and appropriate monitoring tailored to your health needs.
