Zemplar is indicated in the treatment and prevention of high levels of parathyroid hormone, a natural substance produced by the body in patients with long-term renal impairment.Â
A lack of calcium and a specific type of vitamin D can cause an excess of parathyroid hormone. If not treated properly, it can lead to high blood calcium levels (hypercalcaemia), which may cause symptoms like:
- Nausea and vomiting
- Drowsiness and confusion
- Dehydration
- Muscle spasms.
- Bone pain
- Joint tenderness or pain
- Irregular heartbeats.
It might also lead to significant bone abnormalities and osteoporosis.
