Furosemide is a loop diuretic available via prescription used to deal with fluid retention (edema) in puppies, cats, and horses with congestive coronary heart failure, liver disease, or positive kidney ailment. Furosemide is likewise used to deal with excessive blood pressure. Do no longer give this “Lasix medicine” if your pet or horse is not urinating.
Dogs with congestive heart failure have a range of bothersome symptoms, not least of which is a frequent cough caused by fluid retention in the lungs. Allowing this fluid to remain in the lungs forces the heart to work harder and can throw the animal into respiratory and cardiac arrest. Using Lasix to control this build-up increases the life of the dog and gives the patient a better quality of life.
Lasix is the generic name for the drug furosemide, a diuretic used routinely in veterinary medicine. This medication works by preventing sodium and potassium from being kept in the dog’s kidneys, which leads to increased urine output. This allows the kidneys to remove excess fluid from the animal’s body. It also acts as a blood vessel expander in the heart and kidneys. The blood vessels in both organs expand so that blood flows more freely and organs become more functional.
Veterinarians usually prescribe Lasix for a dog diagnosed with congestive heart failure and used mainly to relieve edema or fluid build-up, in the lungs and abdominal cavity. This will relieve cough associated with heart disease. Lasix can also be used in the early stages of kidney disease, but it is usually stopped after the disease progresses and the drug is no longer effective. An animal with electrolyte imbalances, such as high calcium and high potassium, can also be described because it causes these chemicals to get rid of in the urine. Lasix is distributed in pill form to pet owners but can be used as an injectable drug in a clinical setting. When a veterinarian is given intravenously, the dog usually urinates for five minutes.
The recommended dose of Lasix is 1 to 2 milligrams per pound of dog weight once or twice a day at intervals of six to eight hours. The dose may be increased or reduced depending on the severity of the disease and the veterinarian’s diagnosis.
Since Lasix causes the dog’s body to produce normal potassium in the urine, electrolyte levels should be checked frequently. When potassium levels drop dramatically, the dog’s heart treatment may fail and the animal may enter into both heart and kidney failure. Patients will also need to be closely monitored for a returning cough, and the vet will have to frequently check liver and kidney functions.
Dogs will urinate on Lasix frequently, which can lead to contamination of the house and often be requested to be taken outside the home. They may also experience some stomach upset and dehydration and will need to see a veterinarian immediately in case of vomiting, lethargy, or decreased urine production. Some dogs with some antibiotics have suffered hearing loss associated with mixing drugs, but hearing often returns after stopping Lasix. Concurrent use of both antibiotics and Lasix may lead to kidney problems. In some animals, Lasix has been shown to interfere with other prescribed cardiac procedures such as enalapril, which loses its effectiveness in controlling heart disease.
How long does Lasix take to work on a dog?
The diuretic effects of furosemide occur within minutes after intravenous injection, with a peak effect at about thirty minutes. Start of work after oral administration about an hour.
What are the side effects of Lasix in dogs?
Possible side effects
It may include dehydration with excessive thirst and increased or decreased urine production; electrolyte imbalances (for example, low sodium, potassium or calcium), often with rapid heart rate, weakness, depression, vomiting, and insomnia.
