Therapy should be individualized according to patient response. Use the smallest dosage necessary to achieve the required response.
The usual adult dosage is 500 mg to 1000 mg (10 mL to 20 mL) once or twice a day. Many patients with edema respond to intermittent therapy, i.e., administration on alternate days or on three to five days each week. With an intermittent schedule, excessive response and the resulting undesirable electrolyte imbalance are less likely to occur.
