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

Summary:

Drug interactions are reported among people who take Mefenamic acid (mefenamic acid) 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 cytokine release syndrome among females and pyrexia among males.

The phase IV clinical study analyzes what interactions people have when they take Mefenamic acid and Multivitamin. It is created by eHealthMe based on reports of 87 people who take the same drugs from the FDA, and is updated regularly.
