This combination medication is used with or without
other medications to treat high blood pressure (hypertension). Lowering
high blood pressure helps prevent strokes, heart attacks, and kidney
problems.
This product contains two medications. Pindolol is a
beta blocker that works by blocking the effect of certain natural chemicals
(such as epinephrine) on the heart and blood vessels. This slows your
heartbeat, lowers blood pressure, and reduces strain on the heart.
Hydrochlorothiazide is a "water pill" (diuretic) that works by increasing
the amount of urine that you make. This causes your body to get rid of
extra salt and water, which probably helps to relax the blood vessels so
that blood can flow more easily. These two drugs are used together when one
medication is not controlling your blood pressure.
This medication is not recommended as the first
medication for treating high blood pressure. Your doctor will usually start
you on the individual medications first, and then switch you over to this
combination product if this is the best dose combination for
you.
See also Warning section.
Take this medication by mouth with or without food as
directed by your doctor, usually once daily. It is best to avoid taking
this medication within 4 hours of your bedtime to avoid having to get up to
urinate. Consult your doctor or pharmacist if you have questions about your
dosing schedule.
The dosage is based on your medical condition and
response to treatment.
If you also take certain drugs to lower your cholesterol
(bile acid-binding resins such as cholestyramine or colestipol), take this

medications.

benefit from it. To help you remember, take it at the same time each day.
Keep taking this medication even if you feel well. Most people with high
blood pressure do not feel sick. It may take up to several weeks before you
get the full benefit of this drug.
Tell your doctor if your condition does not get better
or if it gets worse (your blood pressure readings remain high or
increase).
