Lasix is a powerful diuretic.
Lasix is prescribed to treat excessive fluid accumulation and swelling (edema) of the body caused by:
- Chronic kidney;
- Heart failure;
- Nephrotic syndrome;
It is sometimes prescribed in conjunction with other blood pressure pills to treat high blood pressure.
Lasix is prescribed in the treatment of high blood pressure and other conditions that require the elimination of excess fluid (water) from the body. These conditions include congestive heart failure, cirrhosis of the liver, and kidney disease. When prescribed to treat high blood pressure, Lasix is effective alone or in combination with other high blood pressure medications. Diuretics help your body produce and eliminate more urine, which helps lower blood pressure. Lasix is classified as a "loop diuretic" because of its point of action in the kidneys.
Lasix is also prescribed with other drugs in people with fluid accumulation in the lungs.

Your doctor will adjust the dosages of this strong diuretic to meet your specific needs.
You will probably be started at a single dose of 20 to 80 mg. If needed, the same dose can be repeated 6 to 8 hours later, or the dose may be increased. Your doctor may raise the dosage by 20 mg or 40 mg with each successive administration--each 6 to 8 hours after the previous dose--until the desired effect is achieved. This dosage is then taken once or twice daily thereafter. Your doctor should monitor you carefully using laboratory tests. The maximum daily dose is 600 mg.
High Blood Pressure
The usual starting dose is 80 mg per day divided into 2 doses. Your doctor will adjust the dosages and may add other high blood pressure medications if Lasix is not enough.
The usual initial dose is 2 mg per 2.2 pounds of body weight given in a single oral dose. The doctor may increase subsequent doses by 1 to 2 mg per 2.2 pounds. Doses are spaced 6 to 8 hours apart. A child's dosage will be adjusted to the lowest needed to achieve maximum effect, and should not exceed 6 mg per 2.2 pounds.
