Chlorthalidone


Chlorthalidone

Brand names: Thalitone

Why is Chlorthalidone prescribed?

Thalitone is a diuretic (water pill) used to treat high blood pressure and fluid retention associated with congestive heart failure, cirrhosis of the liver (a disease of the liver caused by damage to its cells), corticosteroid and estrogen therapy, and kidney disease. When used for high blood pressure, Thalitone may be used alone or in combination with other high blood pressure medications. Diuretics help your body produce and eliminate more urine, which helps lower blood pressure.

Most important fact about Chlorthalidone

If you have high blood pressure, you must take Thalitone regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Thalitone; and you must continue taking it even if you are feeling well. Thalitone does not cure high blood pressure; it merely keeps it under control.

How should you take Chlorthalidone?

Diuretics such as Thalitone increase urination; therefore Thalitone should be taken in the morning.

Do not interchange generic chlorthalidone with Thalitone without consulting your doctor or pharmacist.

Thalitone may be taken with food. Take it exactly as prescribed.

--If you miss a dose...

Take it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at the same time.

--Storage instructions...

Store at room temperature.
