Question: is lasix used for chf?
Answer: Use loop diuretics (like furosemide [Lasix]) in most NYHA class II through IV patients in dosages adequate to relieve pulmonary congestive symptoms. Double the dosage (instead of giving twice daily) if there is no response or if the serum creatinine level is > 2.0 mg per dL (180 μmol per L).
