High blood calcium levels (hypercalcemia) can increase the risk for irregular heartbeat and seizures among people who have a history of these conditions. Hypercalcemia can also increase the effects of digitalis. Let your doctor know right away if you develop any of the following symptoms while taking Zemplar:

You can help prevent hypercalcemia by taking Zemplar exactly as directed by your doctor. Do not take any other forms of vitamin D, such as over-the-counter supplements or other vitamin D prescription medicines, unless directed by your doctor. Taking too much vitamin D can lead to hypercalcemia and other serious problems. Hypercalcemia caused by an overdosage of vitamin D can become severe and may require emergency medical attention. In addition, you should follow your doctor's recommendations for controlling your intake of calcium and phosphorus. High intake of calcium and phosphorus during treatment with Zemplar can also lead to hypercalcemia.
