Generic Name: methyldopa/hydrochlorothiazide (meth-ill-DOE-pa/hye-droe-klor-oh-THYE-a-zide)
Brand Name: Aldoril
Aldoril is used for:
Treating high blood pressure.
Aldoril is an antihypertensive and thiazide diuretic combination. It works by relaxing and widening blood vessels and by making the kidneys eliminate sodium (salt) and water from the body, which helps to lower blood pressure.
Do NOT use Aldoril if:
- you are allergic to any ingredient in Aldoril or to other sulfonamide-derived drugs
- you have severe liver disease (eg, acute hepatitis, cirrhosis), previous liver problems due to methyldopa, adrenal gland problems (eg, pheochromocytoma), or an inability to urinate
- you have a history of autoimmune hemolytic anemia
- you are taking dofetilide, ketanserin, lithium, or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine)
Contact your doctor or health care provider right away if any of these apply to you.
