Vitamins and Zelnorm drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Vitamins (ascorbic acid; biotin; cyanocobalamin; dexpanthenol; ergocalciferol; folic acid; niacinamide; pyridoxine hydrochloride; riboflavin phosphate sodium; thiamine hydrochloride; vitamin a; vitamin e) and Zelnorm (tegaserod maleate). Common drug interactions include spondylolysis among females and dry skin among males.

The phase IV clinical study analyzes what interactions people have when they take Vitamins and Zelnorm. It is created by eHealthMe based on reports of 42 people who take the same drugs from the FDA, and is updated regularly.
