Calcijex (calcitriol injection) is a man-made form of vitamin D3 used to treat or prevent low calcium levels in patients undergoing long-term kidney dialysis. Calcijex is usually used along with diet, supplements, and sometimes other medications. Calcijex is available in generic form. Common side effects of Calcijex include nausea, headache, constipation, pain/discomfort at the injection site, dry mouth, loss of appetite, or stomach upset.
The optimal dose of Calcijex is individually determined for each patient. Calcijex may interact with digoxin, steroids, magnesium-containing medications, phosphate binders, diuretics, supplements that contain vitamin D, or anticonvulsants. Tell your doctor all medications and supplements you use. During pregnancy, Calcijex should be used only if prescribed. It is unknown if Calcijex passes into breast milk. Consult your doctor before breastfeeding.

Calcijex FDA Prescribing Information: Side Effects
Adverse Drug Reaction Overview
The following adverse reactions have been reported in association with CALCIJEX® (calcitriol injection) treatment.
The less frequently reported adverse effects were headache, nausea, vomiting, constipation, abdominal cramp, pruritis, conjunctivitis, agitation, extremity pain, apprehension, polyuria, insomnia, elevated serum glutamic oxaloacetic transaminase (SGOT) and/or serum glutamic pyruvic transaminase (SGPT), elevated alkaline phosphatase, hypercalciuria, hypermagnesemia, hyperphosphatemia, elevated lymphocytes, elevated hematocrit, elevated neutrophils, and elevated hemoglobin.
The adverse effects of CALCIJEX® are, in general, similar to those encountered with excessive vitamin D intake. The early and late signs and symptoms associated with vitamin D intoxication and hypercalcemia are:
Polyuria, polydipsia, decreased appetite, weight decreased, nocturia, conjunctival deposit, pancreatitis, photophobia, rhinorrhoea, pruritus, hyperthermia, libido decreased, blood urea increased, albuminuria, hypercholesterolemia, aspartate aminotransferase increased, alanine aminotransferase increased, calcinosis, hypertension, cardiac arrhythmias, muscular weakness, paresthesia, dehydration, apathy, urinary tract infections, and rarely, overt psychosis.
Clinical Trial Adverse Drug Reactions
Because clinical trials are conducted under very specific conditions the adverse reaction rates observed in the clinical trials may not reflect the rates observed in practice and should not be compared to the rates in the clinical trials of another drug. Adverse drug reaction information from clinical trials is useful for identifying drug-related adverse events and for approximating rates.
CALCIJEX® was studied in 20 patients undergoing maintenance hemodialysis for chronic renal disease (see Clinical Trials, Study CP5691). This open-label study had no comparator; each patient served as his/her own control. Patients received CALCIJEX® three times weekly, post-dialysis over a treatment period of 4 to 8 weeks. Doses were titrated for each patient based upon serum total calcium response.
Abnormal Hematologic And Clinical Chemistry Findings
The most frequently reported adverse effect is hypercalcemia (35% approximately after the 4th week of treatment).
Post-Market Adverse Drug Reactions
Hypersensitivity reactions have been commonly reported in Post-Market Clinical Trials at a frequency of 2.3%. Rare postmarketing reports of anaphylaxis have also been received. Occasional mild pain and localized redness at the injection site have been observed. The adverse drug reactions occurring in patients receiving CALCIJEX® in seven Post Market Clinical Studies are summarized for a total of 485 subjects randomized to CALCIJEX® (Table 1).
