Calcitriol is the active form of vitamin D, normally made in the kidney.[10] A manufactured form is used to treat kidney disease with low blood calcium, hyperparathyroidism due to kidney disease, low blood calcium due to hypoparathyroidism, osteoporosis, osteomalacia, and familial hypophosphatemia.[7][8] It is taken by mouth or by injection into a vein.[7]
Excessive amount commonly results in weakness, headache, nausea, constipation, urinary tract infections, and abdominal pain.[7][8] Serious side effects may include high blood calcium and anaphylaxis.[7] Regular blood tests are recommended after the medication is started and when the dose is changed.[8] Calcitriol increases blood calcium (Ca2+) mainly by increasing the uptake of calcium from the intestines.[7]
Calcitriol was approved for medical use in the United States in 1978.[7] It is available as a generic medication.[8] A month supply in the United Kingdom costs the NHS about 9.70 £ as of 2019.[8] In the United States the wholesale cost of this amount is about US$27.[11] In 2017, it was the 256th most commonly prescribed medication in the United States, with more than one million prescriptions.[12][13]
