<p><strong>Congestive heart failure:</strong>&nbsp;The usual initial oral dose is 10 mg or 20 mg once daily. If the diuretic response is inadequate, the dose should be titrated upward by approximately doubling until the desired diuretic response is obtained. Single doses higher than 200 mg have not been adequately studied.<br />
<br />
<strong>Chronic renal failure</strong>: The usual initial oral dose is 20 mg once daily. lf the diuretic response is inadequate, the dose should be titrated upward by approximately doubling until the desired diuretic response is obtained. Single doses higher than 200mg have not been adequately studied.<br />
<br />
<strong>Hepatic cirrhosis</strong>: The usual initial oral dose is 5 mg or 10 mg once daily, administered together with an aldosterone antagonist or a potassium sparing diuretic. If the diuretic response is inadequate, the dose should be titrated upward by approximately doubling until the desired diuretic response is obtained. Single doses higher than 40 mg have not been adequately studied. Chronic use of any diuretic in hepatic disease has not been studied in adequate and well-controlled trials.<br />
<br />
<strong>Hypertension</strong>: The usual initial oral dose is 2.5-5 mg once daily. If the 5 mg dose does not provide adequate reduction of blood pressure within 4 to 6 weeks, the dose may be increased to 10 mg once daily. If the response to 10 mg is insufficient, an additional antihypertensive should be added to the treatment regimen.</p>
