Who should not take Zemplar?

  • You should not take Zemplar if you have signs of toxic levels of vitamin D or an abnormally high amount of calcium in your blood.
  • It is important for you and your doctor to be aware of the symptoms of too much calcium, (e.g., weakness, headache, excessive sleepiness, nausea, vomiting, dry mouth, constipation, muscle spasm or bone pain). If you have these symptoms, your doctor may want to lower the dose of Zemplar or stop the drug until your calcium level returns to normal.

General Precautions with Zemplar: 

Your doctor will monitor you closely if you are taking the drug digoxin along with Zemplar.

Zemplar is administered as an injection during dialysis treatment, no more than every other day.

In order to ensure Zemplar’s effectiveness, diet is important. Your doctor may want you to:

What should I tell my doctor or health care provider?

Because certain other medications can interact with Zemplar, (e.g., digoxin), review all medications that you are taking with your health care provider, including those that you take without a prescription.
