Generic Name: hydrochlorothiazide and methyldopa (Pronunciation: HYE droe KLOR oh THYE a zide and METH il DOE pa)

What is hydrochlorothiazide and methyldopa (Aldoril 15, Aldoril 25)?

Methyldopa lowers blood pressure by decreasing the levels of certain chemicals in your blood. This allows your blood vessels (veins and arteries) to relax (widen) and your heart to beat more slowly and easily.

Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

The combination of hydrochlorothiazide and methyldopa is used to treat high blood pressure (hypertension).

Hydrochlorothiazide and methyldopa may also be used for purposes not listed in this medication guide.
