Aleve and Flecainide acetate drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Aleve (naproxen sodium) and Flecainide acetate (flecainide acetate). Common drug interactions include constipation among females and akathisia among males.

The phase IV clinical study analyzes what interactions people have when they take Aleve and Flecainide acetate. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
