Who should not be treated with Hectorol?

  • People with a high level of calcium in the blood.
  • People with signs of extremely high levels of vitamin D.

Special Warnings with Hectorol:

  • Periodic monitoring of your condition by your doctor is important while being treated with Hectorol.
  • Because Hectorol affects the absorption of calcium be the body, it is important for you and your doctor to be aware of the early symptoms of too much calcium in your blood, including weakness, headache, excessive sleepiness, nausea, vomiting, dry mouth, constipation, muscle pain, bone pain and metal taste in your mouth. If you have these symptoms, contact your doctor right away. Later symptoms include frequent need to urinate, loss of appetite, weight loss, pink eye, sensitivity to sunlight, nasal discharge, skin itching, and fever.

General Precautions with Hectorol:

  • Do not take Hectorol with magnesium containing antacids, because these may cause too much magnesium to build up in your body.
  • Do not take Hectorol with mineral oil or cholesterol-lowering drugs containing cholestyramine, because these may reduce the amount of Hectorol absorbed by your body.

What should I tell my doctor or health care provider?

Because certain other medications can interact with Hectorol, review all medications that you are taking with your health care provider, including those that you take without a prescription.

Tell your health care provider if you are trying to become pregnant, are already pregnant, or are breast-feeding.
