Testim and Multivitamin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Testim (testosterone) and Multivitamin (ascorbic acid; biotin; cyanocobalamin; dexpanthenol; ergocalciferol; folic acid; niacinamide; pyridoxine hydrochloride; riboflavin phosphate sodium; thiamine hydrochloride; vitamin a; vitamin e). Common drug interactions include nausea among females and acute myocardial infarction among males.

The phase IV clinical study analyzes what interactions people have when they take Testim and Multivitamin. It is created by eHealthMe based on reports of 66 people who take the same drugs from the FDA, and is updated regularly.
