Letrozole and Efudex drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Letrozole (letrozole) and Efudex (fluorouracil). Common drug interactions include malignant neoplasm progression among females.
The phase IV clinical study analyzes what interactions people have when they take Letrozole and Efudex. It is created by eHealthMe based on reports of 16 people who take the same drugs from the FDA, and is updated regularly.
