Vitamins and Atrioventricular block second degree - a phase IV clinical study of FDA data

Summary:

Atrioventricular block second degree is reported as a side effect 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), especially for people who are female, 60+ old, also take Gilenya, and have Multiple sclerosis.

The phase IV clinical study analyzes which people have Atrioventricular block second degree when taking Vitamins. It is created by eHealthMe based on reports of 121,858 people who have side effects when taking Vitamins from the FDA, and is updated regularly.
