What Is Furosemide for Dogs and Cats?
Furosemide is a drug used to prevent fluid build-up in the lungs or abdomen in pets with congestive heart failure, liver disease, or kidney disease.
Make sure your pet has plenty of water to drink when they are on this drug. Closely monitor your pet for signs of dehydration.
How It Works
Furosemide prevents a certain area of the kidneys from absorbing nutrients such as chloride, sodium, potassium and water. This removes excess fluids from your pet’s body and increases the amount and frequency of urination.
Store in a tightly sealed container at room temperature protected from light and heat.
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
