Calcium ascorbate and Colecalciferol drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Calcium ascorbate (vitamin c (ascorbic acid)) and Colecalciferol (cholecalciferol). Common drug interactions include headache among females and cerebrovascular accident among males.

The phase IV clinical study analyzes what interactions people have when they take Calcium ascorbate and Colecalciferol. It is created by eHealthMe based on reports of 20 people who take the same drugs from the FDA, and is updated regularly.
