What is hydrochlorothiazide and bisoprolol?

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


Bisoprolol is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).


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


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


What is the most important information I should know about hydrochlorothiazide and bisoprolol?


You should not use this medication if you have severe or uncontrolled heart failure, a heart condition called "sick sinus syndrome" or "AV block," slow heartbeats, an allergy to sulfa drugs, or if you are unable to urinate.

Before using this medication, tell your doctor if you have congestive heart failure, circulation problems, kidney or liver disease, cirrhosis, glaucoma, asthma, bronchospastic lung disease, a thyroid disorder, lupus, gout, diabetes, or a penicillin allergy.


If you are diabetic, check your blood sugar carefully. Using bisoprolol can make it harder for you to tell when you have low blood sugar. Your insulin or diabetic medication needs may change while you are taking hydrochlorothiazide and bisoprolol. Talk with your doctor before changing any doses.


Drinking alcohol can further lower your blood pressure and may increase certain side effects of hydrochlorothiazide and bisoprolol.

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.


Keep using this medication even if you feel fine. High blood pressure often has no symptoms.
