Furosemide

What condition does Furosemide treat?

Furosemide is used to decrease extra fluid in the body. It is called edema which is caused by conditions like:

  • Liver disease
  • Heart failure
  • Kidney disease

This can lessen symptoms such as:

  • Swelling in your legs, arms, or abdomen
  • Shortness of breath

This drug may also be used to treat high blood pressure. Lowering it may help prevent heart attacks, strokes, or kidney problems.

Furosemide belongs to the family of medications called diuretics. A diuretic helps lessen the amount of fluid in the body. It is by increasing the amount of urine produced. This comes as a tablet for oral use. The Food and Drug Administration (FDA) has approved this medication.

How does Furosemide work?

Furosemide works by blocking the absorption of chloride, sodium, and water. It is the filtered fluid in the kidney tubules that causes a profound increase in the output of urine. The beginning of action after oral use is within an hour and the diuresis lasts about 6 to 8 hours.

The diuretic effect of this drug may cause depletion of chloride, sodium, body water, and other minerals. Therefore, careful therapeutic supervision is needed during treatment. 

What is the recommended dosage for Furosemide?

The recommended dosage is based on your medical condition and response. It is important to take the prescription exactly as it is given to you.

The tablet is to be taken by mouth with a full glass of water. It is usually taken once or twice a day. You may take each dose with or without food. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate. Remember to take it at the same time every day.

Cholestyramine, Sucralfate, and Colestipol can reduce the absorption of furosemide. If you are taking any of these medications, separate the timing of each dosage from this medication by at least 2 hours.
