Furosemide Basics

Furosemide treats congestive heart failure, pulmonary edema (fluid in the lungs), high blood pressure, high calcium and potassium levels, liver disease, and some kidney diseases. It is a potent diuretic drug used in animals who suffer from fluid retention. Most often, it is used in dogs and cats to reduce fluid accumulation and prevent further edema. It prevents the absorption of chloride, sodium, potassium, and water, leading to increased urine production. Increased urine production helps the kidneys remove excess fluid from the lungs and body cavities.

Furosemide requires a prescription from your veterinarian. It comes in two forms: a tablet and an oral suspension.

Furosemide Directions

Use as directed by your veterinarian, and always follow the instructions printed on the prescription label. Complete the entire prescription unless instructed otherwise by your veterinarian. Allow your pet access to plenty of water while administering this medication. Store at room temperature.

Furosemide Warnings

Keep out of the reach of children and pets. Do not use in animals with known hypersensitivity to this medication or other sulfa drugs. Use with caution in pets that are is pregnant or lactating. Use with caution if your pet suffers from kidney failure, dehydration, electrolyte abnormalities, diabetes, or liver disease. Periodic bloodwork is necessary to monitor kidney and liver values. This drug is a diuretic, so your pet should be drinking and urinating more frequently. This medication may also cause sensitivity to sunlight. If you notice these or any other behavioral or physiological changes in your pet while administering furosemide, contact your veterinarian immediately. 

Finally, furosemide may interact with some other medications. Therefore, inform your veterinarian of any and all medications your pet may be taking. This is especially important if your pet is currently taking other heart and blood pressure medications, such as theophylline, steroids, digoxin, or aspirin.

Adverse reactions and serious side effects are rare, however, they can occur. In the case of a more serious reaction, seek veterinary attention immediately. Common signs of a more serious reaction include facial swelling, breathing difficulties, fainting, fever, hair loss, lesions, dark urine, or yellowing of the skin.
