Furosemide is a prescription medication used to treat high blood pressure and edema (fluid retention) associated with congestive heart failure, liver cirrhosis, and kidney disease.

Furosemide is prescribed to manage conditions such as:

• Edema associated with congestive heart failure, liver cirrhosis, or kidney disease
  
• Hypertension (high blood pressure)
  
  

By reducing the amount of excess fluid in the body, furosemide helps alleviate swelling and reduces the workload on the heart.

Furosemide is classified as a diuretic (also known as a water pill). These drugs help your kidneys release extra salt and water into the urine, lowering the overall fluid levels in the body. Not only does this help reduce the symptoms of edema, but it can also help lower blood pressure by decreasing the amount of fluid in the veins and arteries.

Furosemide is available in the following forms:

• Oral tablets
  
• Oral solution
  
  

The dosage and frequency of use depend on the condition being treated, its severity, and how you respond to the medication.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.

Furosemide is used to manage edema and hypertension. The effects can be noticeable within a few hours, but achieving the desired control over your condition may take a few days.

Continue using furosemide as prescribed, even if you start feeling better. Regular use according to your prescription is crucial for the management of your condition.

While furosemide is primarily used for treating edema and hypertension, healthcare providers may prescribe it off-label for other conditions such as hypercalcemia (high calcium levels in the blood).

Discuss any alternative uses of furosemide with your healthcare provider.

Furosemide is available in the following dosage forms:

• Oral tablets
  
• Oral solution
  
  

Furosemide is a prescription medication. You will need a valid prescription from a licensed healthcare provider to obtain this medication.
