Hectorol (doxercalciferol injection) is a synthetic (man-made) form of vitamin D used to reduce elevated intact parathyroid hormone (iPTH) levels in the treatment of secondary hyperparathyroidism in patients undergoing chronic renal dialysis. Contact your doctor if you experience side effects of Hectorol including nausea, vomiting, decreased appetite, dry mouth, constipation, weakness, headache, dizziness, metallic taste, muscle or bone pain, increased thirst or urination, shortness of breath, or itching.

The optimal dose of Hectorol is carefully determined for each patient. The recommended initial dose is 4 mcg administered intravenously as a bolus dose three times weekly at the end of dialysis (approximately every other day). Hectorol may interact with antacids containing magnesium, digoxin, vitamin D supplements, mineral oil, or cholestyramine. Tell your doctor all medications and supplements you use. Do not take Hectorol without first talking to your doctor if you are pregnant. It is unknown if this drug passes into breast milk. It is believed this drug could affect a nursing baby. Do not take Hectorol if you are breastfeeding.
