Thalitone Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Thalitone (chlorthalidone) is a thiazide diuretic (water pill) used to treat fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or kidney disorders, or edema caused by taking steroids or estrogen. Thalitone is also used to treat high blood pressure (hypertension). Common side effects of Thalitone include dizziness, lightheadedness, headache, blurred vision, loss of appetite, stomach upset, diarrhea, or constipation as your body adjusts to the medication. Other side effects of Thalitone include muscle spasm, decreased sexual ability, or increased sensitivity to the sun.
To treat hypertension the usual starting dose of Thalitone is a single daily dose of 15 mg. If the response is insufficient, the dosage may be increased to 30 mg and then to a single daily dose of 45-50 mg. To treat edema in adults, initial dose is 30 to 60 mg daily or 60 mg on alternate days. Maintenance dose is usually lower. Thalitone may interact with other medicines that make you sleepy (such as cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety), lithium, digoxin, steroids, other blood pressure medications, insulin or oral diabetes medicine. Tell your doctor all medications you use. Thalitone should be used only when prescribed during pregnancy. This drug passes into breast milk. While there have been no reports of harm to nursing infants, consult your doctor before breast-feeding.
