Hydrochlorothiazide and Cataflam drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Hydrochlorothiazide (hydrochlorothiazide) and Cataflam (diclofenac potassium). Common drug interactions include mass among females and mental disorder among males.

The phase IV clinical study analyzes what interactions people have when they take Hydrochlorothiazide and Cataflam. It is created by eHealthMe based on reports of 45 people who take the same drugs from the FDA, and is updated regularly.
