Frusemide belongs to a class of medications called loop diuretics. It works by balancing the amount of salt and water in your body resulting in an increase in the volume of your urine output. Frusemide can be used to treat oedema and high blood pressure.
Frusemide can be taken by mouth as tablets or given by injection. Since Frusemide is a very effective diuretic, your dose will be adjusted based on your response. Usual adult oral doses range from 20 to 40 mg daily in the morning. For maintenance dosing, Frusemide can be taken once or twice daily. If taken twice daily, most people take the second dose around lunchtime so as to avoid excessive urination overnight.
