Fusid Plus is a combination tablet containing Furosemide 20 mg and Spironolactone 50 mg, used primarily to manage conditions related to fluid overload and high blood pressure. Furosemide is a loop diuretic that helps remove excess water and salt from the body, while Spironolactone is a potassium-sparing diuretic that prevents the loss of potassium. Together, they effectively reduce swelling (edema), treat hypertension, and manage fluid retention in conditions like heart failure, liver cirrhosis, and kidney disorders, while maintaining electrolyte balance.
