Hypercalcaemia due to Hypervitaminosis D in a Self-Supplementing Multiple Sclerosis Patient: A Case Report

We report the case of a 45 year-old male with MS who presented with symptomatic hypercalcaemia secondary to self-supplementation of vitamin D3 purchased online. Treatment was with IV hydration, glucocorticoids, calcitonin and bisphosphonates. This case highlights a lack of consensus guidance regarding safe vitamin D supplementation dosages and the importance of a thorough history with regard to non-prescribed supplements, particularly those easily available online.
