Premarin and Rowasa drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Premarin (estrogens, conjugated) and Rowasa (mesalamine). Common drug interactions include abdominal pain among females.
The phase IV clinical study analyzes what interactions people have when they take Premarin and Rowasa. It is created by eHealthMe based on reports of 13 people who take the same drugs from the FDA, and is updated regularly.
