What Is Hydrochlorothiazide Methyldopa?
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.
You should not use this medication if you are allergic to methyldopa (Apresoline) or hydrochlorothiazide, if you are unable to urinate, or if you have liver disease (including cirrhosis or hepatitis), or a history of liver problems caused by taking methyldopa.
Do not use hydrochlorothiazide and methyldopa if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.
Before using hydrochlorothiazide and methyldopa, tell your doctor if you have kidney disease (or are on dialysis), angina pectoris (chest pain), glaucoma, asthma, gout, lupus, diabetes, an allergy to sulfa drugs or penicillin, or if you have ever had a stroke.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
