Lasix FAQs

How Does Lasix Work?

Lasix causes your kidneys to get rid of extra salt and water from your body through your urine. This helps to reduce water retention.

What Are the Associated Dosages and Treatments for Lasix?

The dosage of Lasix will vary depending on why you need it and how severe your condition is.

You may start off on a dose as low as 20 mg and end up on a dose as high as 600 mg per day, although most doses will be in the low to middle end of this range.

Always follow your doctor’s instructions when taking Lasix. Your doctor may want you to take it once or twice a day. Either way, avoid taking Lasix too late in the evening since it causes increased urination.

What Are the Benefits of Lasix?

Lasix removes excess salt and water in your blood, which can improve blood pressure as well as edema related to a kidney disorder, liver disease, or congestive heart failure.
