Frasix 40 Tablet contains Furosemide 40mg, a potent loop diuretic used primarily to treat fluid retention (edema) associated with congestive heart failure, liver cirrhosis, and kidney disorders, as well as hypertension. Furosemide works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys, promoting increased urine output and thereby reducing excess fluid buildup in the body. This action helps alleviate symptoms such as swelling, shortness of breath, and high blood pressure. Frasix 40 is typically prescribed when rapid and effective diuresis is needed. Patients should take this medication under medical supervision, as improper use can lead to dehydration, electrolyte imbalances (such as low potassium or sodium), and kidney dysfunction. Common side effects may include increased urination, dizziness, and muscle cramps. It is important to monitor kidney function and electrolyte levels during treatment. Frasix 40 should be used cautiously in patients with diabetes, gout, or those taking other medications that affect kidney function or electrolyte balance. Always follow the prescribed dosage and consult a healthcare professional before starting or stopping this medication to ensure safe and effective treatment.
