Hectorol (doxercalciferol) Disease Interactions

There are 2 disease interactions with Hectorol (doxercalciferol):


Vitamin D analogs (applies to Hectorol) hypercalcemia

Major Potential Hazard, Moderate plausibility. Applicable conditions: Malabsorption Syndrome

Vitamin D analogs such as calciferol and ergocalciferol should not be given to patients with hypercalcemia, malabsorption syndrome, or evidence of vitamin D toxicity.


Vitamin D analogs (applies to Hectorol) hepatobiliary dysfunction

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease, Biliary Obstruction

Vitamin D analogs are fat soluble and oral formulations require bile for adequate intestinal absorption. Hepatic and/or biliary dysfunction decrease the absorption of vitamin D analogs. Metabolites of vitamin D analogs are primarily excreted in bile and feces. Ergocalciferol, cholecalciferol, and dihydrotachysterol undergo hepatic hydroxylation during metabolic activation. Hepatic impairment can alter the metabolic and therapeutic activity of certain vitamin D analogs. Alternative vitamin D analogs such as calcifediol (requires renal activation) and calcitriol (active form) may be considered in patients with compromised hepatic function.
