Phenergan and Zestoretic drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Phenergan (promethazine hydrochloride) and Zestoretic (hydrochlorothiazide; lisinopril). Common drug interactions include diabetes mellitus among females and pain among males.
The phase IV clinical study analyzes what interactions people have when they take Phenergan and Zestoretic. It is created by eHealthMe based on reports of 32 people who take the same drugs from the FDA, and is updated regularly.
