Frusenex 100 Tablet contains Furosemide 100mg, a potent loop diuretic used primarily to treat edema associated with congestive heart failure, liver cirrhosis, and renal disease, including nephrotic syndrome. By inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle, Frusenex promotes increased urine output, effectively reducing fluid accumulation in the body. This action helps alleviate symptoms such as swelling, shortness of breath, and hypertension caused by excess fluid retention. Frusenex is also prescribed to manage hypertension by decreasing blood volume and vascular resistance. It is typically administered orally, with dosage tailored to the patient's condition and response to therapy. Patients should be monitored for electrolyte imbalances, dehydration, and renal function during treatment, as Furosemide can cause hypokalemia, hyponatremia, and other metabolic disturbances. Common side effects include dizziness, increased urination, and potential hypotension. It is important to use Frusenex under medical supervision, especially in individuals with diabetes, gout, or those taking other medications that affect electrolyte balance. Adequate hydration and regular follow-up are essential to ensure safe and effective use of this medication.
