Generic Name: chlorthalidone (klor-THAL-ih-dohn)
Brand Name: Thalitone
Thalitone is used for:
Treating high blood pressure. It may be used along with other medicines to treat fluid retention caused by certain conditions (eg, heart failure, liver or kidney problems) or medicines (eg, corticosteroids, estrogens). It may also be used for other conditions as determined by your doctor.
Thalitone is a thiazide-like diuretic. It works by increasing elimination of sodium and potassium in the urine, which causes more water to be eliminated.

- you are unable to urinate
Contact your doctor or health care provider right away if any of these apply to you.
