Furosemide Oral Liquid is an ExpressVet exclusive medication that prevents fluid buildup in the lungs and
abdomen of dogs, or cats, with congestive heart failure and some types of kidney diseases. Furosemide is a loop
diuretic, promotes diuresis, the process of extra urination, and helps manage fluid retention so your pets’ body
can get rid of excess liquids and substances. It can also be helpful in treating high blood pressure.
In other animals such as racehorses it has been used to prevent or reduce pulmonary hemorrhage, blood leakage into the lungs brought on from exercise. This medication is given by mouth to your pet, and when on Furosemide it’s important to make sure your pet is drinking plenty of water and stays hydrated.

giving it to them with food. Your pet will urinate more often when receiving this drug, so make sure they have
extra fresh water nearby at all times.
This medication can cause repeated urination, if possible avoid giving it at bedtime. If the person dosing Furosemide is allergic to sulfa medications, wear gloves when handling it. We always recommend consulting with your pet veterinarian before taking.
