How does Rocaltrol compare to nutritional supplements containing either calcium, vitamin D or both?
The goal of treatment with Rocaltrol in chronic kidney disease and hypoparathyroidism is to normalize the levels of calcium and phosphorus in your body. The vitamin D contained in vitamins or other nutritional supplements has to be activated after it is absorbed. Activated forms of vitamin D such as Rocaltrol (calcitriol) have a longer duration of action and are more potent than other forms of this vitamin.
Rocaltrol is more potent than vitamin D found in vitamins or other nutritional supplements.

Important Safety Information for Rocaltrol® (calcitriol) Capsules and Oral solution
Rocaltrol should not be taken if there are symptoms of abnormally elevated vitamin D or calcium levels or if you are allergic to any product ingredient. Taking too much vitamin D can cause high calcium levels, which could trigger serious health problems and may require immediate medical attention. Dosage adjustments of Rocaltrol may be required if other medications are initiated or discontinued; do not stop taking other medications without your physician's knowledge. Potential side effects of Rocaltrol are, in general, similar to effects of taking too much vitamin D. Report early symptoms of elevated vitamin D or calcium including weakness, headache, somnolence, nausea, vomiting, dry mouth, constipation, muscle or bone pain, metallic taste, and anorexia, abdominal pain or stomach ache, to your doctor.
