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.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

HECTOROL Capsules

Adverse reactions in patients with stage 3 or 4 CKD

HECTOROL capsules have been evaluated in two placebo-controlled, double-blind 24 week studies in patients with Stage 3 or 4 CKD. Patients were treated with HECTOROL capsules (n=27) or placebo (n=28) [see Clinical Studies]. Adverse reactions occurring in the HECTOROL capsules group at a frequency of 5% or greater and more frequently than in the placebo group are presented in Table 1.

Adverse Reactions In Patients With CKD On Dialysis

HECTOROL capsules have been evaluated in two placebo-controlled, double-blind studies in patients with CKD on hemodialysis. Patients were treated with HECTOROL capsules (n=61) or placebo (n=61) [see Clinical Studies]. After randomization to two groups, eligible patients underwent an 8-week washout period during which no vitamin D derivatives were administered to either group. Subsequently, all patients received HECTOROL capsules in an open-label fashion for 16 weeks followed by a double-blind period of 8 weeks during which patients received either HECTOROL capsules or placebo. Adverse reactions occurring in the HECTOROL capsule groups at a frequency of 2% or greater, and more frequently than in the placebo group are presented in Table 2.

HECTOROL Injection

Adverse Reactions In Patients With CKD On Hemodialysis

HECTOROL injection has been studied in 70 patients with CKD on hemodialysis in two 12-week, open-label, single-arm, multicenter studies [see Clinical Studies]. The incidence of hypercalcemia and hyperphosphatemia increased during therapy with HECTOROL injection. Patients with higher pretreatment serum levels of calcium (>10.5 mg/dL) or phosphorus (>6.9 mg/dL) were more likely to experience hypercalcemia or hyperphosphatemia.

There was no placebo group included in the studies of HECTOROL injection. Adverse reactions in patients with CKD on hemodialysis receiving HECTOROL injection are expected to be similar to those reported in placebo-controlled studies of HECTOROL capsules presented in Table 2.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of HECTOROL. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.

Hypersensitivity reactions, including fatal outcome, have been reported in patients on hemodialysis following administration of HECTOROL injection. Hypersensitivity reactions include anaphylaxis with symptoms of angioedema (involving face, lips, tongue and airways), hypotension, unresponsiveness, chest discomfort, shortness of breath, cardiopulmonary arrest, pruritus, and skin burning sensation.
