Furosemide Tablets are prescribed in the treatment of swelling associated with heart failure, especially when the swelling is caused by water retention. It's a proven diuretic—a medication that helps remove excess fluid from the body—and saluretic—a medication excess sodium from the kidneys. By relieving the body of excess fluid and sodium, it helps to relieve inflammation and its unpleasant symptoms. Customers may receive this drug under the names Lasix, Frusomide, Salix.


Furosemide is a diuretic used to remove excess fluid from the body. It's indicated in the treatment of congestive heart failure, some other heart diseases, pulmonary edema, certain kidney diseases, high blood pressure, high potassium level in the blood, ascites (fluid in the abdomen), and certain kinds of tissue edema (swelling).

Possible Side Effects

Dehydration with excessive thirst and increased or decreased urine production have been reported. Electrolyte imbalances (e.g., low sodium, potassium, or calcium), often with rapid heart rate, weakness, depression, vomiting, and restlessness are also possible. If you see any of these signs, contact your veterinarian immediately. Rarely, pets may see an increase in blood glucose level, anemia, pale gums, tiredness, or weakness. A decrease in white blood cells, (making your pet more susceptible to infections) and stomach or intestinal disorders (with vomiting or diarrhea) are also possible, but rare.

Drug & Food Interactions

Consult your veterinarian before using furosemide with any other medications, including vitamins and supplements.


Do not use in animals with known allergies to Furosemide or sulfa drugs. Furosemide will cause your pet to urinate more often. Your pet may have more accidents and need to go outside more. Use with caution in pets with kidney disease and diabetes. Do not use in animals with anuria (inability to produce urine), progressive kidney disease, electrolyte imbalances, water loss (dehydration), liver disease, diabetes mellitus, vomiting, or diarrhea. Do not use in pregnant or lactating females.

What is Furosemide?

This is an oral tablet that works as a diuretic in order to help to remove excess fluid from the body when additional fluid develops in the body as a result of heart disease, fluid in the lungs (pulmonary edema), kidney disease, and liver disease. It is also sometimes used to manage hypertension (high blood pressure).

What are the benefits of Furosemide?

  • Generic option that works well.
  • Helps to remove extra fluid from the body due to a variety of medical conditions.
  • Can give as a tablet by mouth (orally).

How is this medication given?

Give tablet(s) with or without food by mouth according to your veterinarian's precise instructions.

Your pet should have water available at all times while taking this medication.

If you are unsure of how to give Furosemide correctly, contact your veterinarian.

How does this medication work?

Furosemide is a diuretic. Diuretics stop the absorption of salt and fluid in the kidney tubules. This causes increased urine output so that excess fluid can be effectively removed from the body.

What results can I expect?

Furosemide is not a cure but it can help to improve your pets clinical symptoms and help him/her to feel better. Furosemide works quickly but only works for a few hours after each dose so it needs to be given at regular intervals in order to maintain its effects.

    It is great to be able to order this medication in the dosage you need for your pet. The only drawback is, it needs to be scored____. Sometimes I have to give my puppy a half a pill and not being scored makes it difficult to break.

    You ask how my pet and I "enjoyed" the prescription diuretic I received. I can't say trying to relieve her pain as she dies from heart disease is in anyway enjoyable but thanks for checking in.

    The price of the medicine was good and the shipment came quickly. However, the dosage was 1 1/2 tablets and some were not cut in half. The tablets are small and crumbled when I tried to cut them.
