It is a diuretic

HYDROCHLOROTHIAZIDE W/TRIAMTERENE

Maxzide is a combination of hydrochlorothiazide, which is a diuretic, and triamterene, a potassium sparing diuretic. Both function to remove excess fluid from the body & are also used in treatment of hypertension (high blood pressure)

Advil is an over-the-counter NSAID pain reliever; "maxzide" is a prescription diuretic. Advil (ibuprofen) can damage the kidneys when used to excess, and any diuretic forces the kidneys to work harder than they normally do.

I do take both, but I'm very careful not to take more than the recommended dose of ibuprofen. I am neither a physician nor a pharmacist; if you want reassurance, consult the pharmacist who gave you the maxzide.

The brands Dyazide and Maxzide, for example, contain the thiazide diuretic hydrochlorothiazide with the potassium-sparing diuretic triamterene
