SIDE EFFECTS: Chlorthalidone generally is well tolerated. Low blood levels of potassium, sodium, and magnesium due to increased excretion via urine. High blood calcium levels also can occur, especially in persons who are taking calcium supplements. Thiazide diuretics such as chlorthalidone increase the levels of uric acid in the blood, but gout (which is caused by high levels of uric acid) rarely occurs. Chlorthalidone can cause high blood sugars in patients with diabetes. Other reported side effects include dizziness, lightheadedness, headache, fatigue, nausea, vomiting, abdominal pain, and constipation.
