Coreg and Hctz drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Coreg (carvedilol) and Hctz (hydrochlorothiazide). Common drug interactions include fatigue among females and chronic kidney disease among males.
The phase IV clinical study analyzes what interactions people have when they take Coreg and Hctz. It is created by eHealthMe based on reports of 356 people who take the same drugs from the FDA, and is updated regularly.
