What is Furosemide Used For?

Furosemide for dogs is used to treat oedema (build-up of fluid in the body which causes swelling) in dogs and cats, including oedema caused by cardiac insufficiency, acute renal dysfunction, or trauma.

Furosemide is a diuretic drug, which means it increases urine production in the body. It prevents water and sodium from being reabsorbed, stimulating the kidneys to produce more urine to excrete them from the body. Your vet may prescribe Furosemide to treat chronic heart failure in dogs.

What is Furosemide Used for in Cats?

The use of Furosemide for cats is the same for dogs in treating build-ups of excess fluid in the body, as well as chronic heart failure and acute renal failure in cats. You can buy furosemide tablets for cats and dogs at Pet Drugs Online in the following sizes:

Please make sure you choose the right size tablet when ordering prescription medication for your pet.

Furosemide is administered orally as a tablet or liquid and can be given with or without food. Once ingested, the medicine works fast, and improvement in your pet's symptoms can be seen in as little as 2 hours.

Always ensure your pet has access to plenty of fresh water when being treated with Furosemide.
