Dyazide and Left ventricular dysfunction - a phase IV clinical study of FDA data

Summary:

Left ventricular dysfunction is reported as a side effect among people who take Dyazide (hydrochlorothiazide; triamterene), especially for people who are female, 60+ old, have been taking the drug for 1 - 6 months also take Coreg, and have Cardiac disorder.

The phase IV clinical study analyzes which people have Left ventricular dysfunction when taking Dyazide. It is created by eHealthMe based on reports of 11,105 people who have side effects when taking Dyazide from the FDA, and is updated regularly.
