Intoxication with vitamin D may lead to severe hypercalcemia, renal failure and occasionally to death. An increasing amount of vitamin D supplement is sold over-the-counter (OTC) or over the internet. Here we present a case were a person obtained vitamin D over the internet and administered 50 000 IE daily to his father for a period of six months, in the pursuit to stop or reverse the progression of a vascular dementia. The treatment resulted in a severe hypercalcemia and recurrent hospitalizations. In cases with an unexplained hypercalcemia, being associated with high levels of 25(OH)-vitamin D3 the possibility of intake of D-vitamin sold without a doctor's prescription should be investigated.
维生素D中毒可能导致严重的高钙血症、肾衰竭，偶尔还会导致死亡。越来越多的维生素D补充剂通过非处方（OTC）或互联网销售。在此，我们报告一例，一名患者通过互联网获取维生素D，并在六个月的时间里每天给他父亲服用50000国际单位，以期阻止或逆转血管性痴呆的进展。该治疗导致了严重的高钙血症和反复住院。在不明原因的高钙血症病例中，若与高水平的25（OH）-维生素D3相关，应调查是否摄入了未经医生处方销售的维生素D。
