Generally, yes! IV furosemide for treatment of ascites in patients with cirrhosis should be avoided for couple of reasons.
First, in contrast to patients with congestive heart failure in whom the absorption of oral furosemide may be impaired due to bowel wall edema, patients with cirrhosis and ascites appear to absorb oral furosemide efficiently, similarly to that of control patients.1 Another reason for avoiding IV furosemide in this setting is the possibility of a significant drop in the GFR with its attendant rise in BUN and serum creatinine, clinically resembling a picture of hepatorenal syndrome.2
Although the mechanism of the adverse effect of IV furosemide on the renal function of patients with cirrhosis is not totally clear, furosemide-induced vasoconstriction, not intrasvascular volume depletion due to sodium wasting, seems to play an important role.3
Nevertheless, certain situations may necessitate the use of IV furosemide in patients with cirrhosis and ascites, such as in single doses to help identify patients who will be responsive to diuretics, and in patients in need of prompt diuresis such as those with concurrent pulmonary edema. In a somewhat reassuring study, a single dose of 80 mg IV furosemide reliably identified cirrhotic patients with ascites responsive to diuretics, without a significant risk of deteriorating renal function.3
