How to Deal with a dog on Lasix: Leaked Info

Many dog owners seem to think that their dog doesn’t need as much medical support as humans. Unfortunately, that’s not true. Over a span of time, unhealthy food habits, infection, injury and many other factors can cause your dog to fell ill. One of the most critical yet profound diseases found commonly in dogs is congestive heart disease and lung fluid retention. As the name suggests, this is about congestion in the lungs between the path to the heart, which adversely affects the heart from pumping blood frequently.

As the heart can’t pump blood properly, fluids accumulate in the chest and lungs, restricting the smooth flow of oxygen and blood in your dog’s body. The symptoms of congestive heart diseases include rapid coughing, panting, restlessness, breathing problems and fatigue. It’s necessary to immediately call the vet when you find any of these symptoms in your ageing dog.

What is Lasix?

While any heart disease can be deadly, congestive heart disease has a proven medication. Lasix(Furosemide) helps reduce the fluid accumulation inside a dog’s body by reducing the absorption of fluids, sodium, chloride, potassium and water. Lasix is a diuretic drug and increases urine formation in kidney; thus, effectively draining the excessive accumulated fluids over time.

It prevents excessive oedema or fluids from accumulating in the chest. As with other potent drugs, Lasix has its share of side effects, and your dog’s health might get adversely affected if you don’t take necessary precautions while feeding Lasix. Apart from congestive heart disease, Lasix can also treat a few other fatal diseases.

Which diseases can Lasix treat?

  • Oedema

While the accumulation of fluids can cause heart diseases, they can also cause swelling in other body parts. These fluids can accumulate in the body cavities and peripherals, leading to a condition called Edema. Lasix can remove these fluids from the dog’s body and treat Edema.

  • Chronic Bronchitis

Lasix can treat dogs who struggle breathing due to Chronic Bronchitis by clearing the airway. It acts as a respiratory dilator and provides relief to dogs struggling from Chronic Bronchitis.

  • Hyperkalemia

High potassium levels in the bloodstream of your dog can lead to a fatal situation called Hyperkalemia. The dog might suffer from bleeding nose due to Hyperkalemia. Lasix reduces potassium levels in the blood by releasing potassium into the bloodstream, thus treating Hyperkalemia.

  • Hypercalcemia

High calcium levels in the bloodstream of your dog result in a severe health condition called Hypercalcemia. Hypercalcemia is dangerous to kidneys and might result in kidney failure if left untreated. Lasix encourages the loss of calcium through urine, helping in the treatment of Hypercalcemia.

  • Acute kidney failure

When your dog suffers from acute kidney failure, the kidneys reduce the production and release of urine. The vet may prescribe Lasix combined with other diuretics to encourage urine production and treating kidney failure.

It’s important to note that Lasix is a prescription drug due to its powerful effects and dangerous side effects. While it can be mandatory to use in extreme fluid accumulation diseases, you should only feed it to your dog after consulting a veterinarian.

Is Furosemide dangerous for dogs?

Furosemide is a potent drug that helps in fluid accumulation by increasing the rate of urine formation, thus putting pressure on your dog’s kidneys. If your dog has a weak kidney or suffers from kidney failure, he shouldn’t be fed Furosemide as it can reduce calcium, salt, potassium and other electrolyte levels.

This can lead to electrolyte imbalance in the body resulting in worsening kidney conditions and a plethora of symptoms like weakness. It can also lead to kidney failures in those having weak kidneys. It’s thus, important to give Furosemide only under the monitoring of a registered vet.

You shouldn’t give your dog Furosemide if he already has dehydration as it can worsen the condition. A proper diet is vital in ensuring the benefits of Furosemide and reducing the harmful effects. If given as a sole medication, Furosemide may cause damage to hearing and imbalance in your dog.

  • Harmful drug interactions with Furosemide

Furosemide may combine dangerously with some drugs so you should always inform your vet if your dog is taking any of the following drugs. The clubbing of Furosemide with any of these drugs may result in a worsening condition of kidneys, dehydration and even liver failure.

ACE inhibitors(benazepril or enalapril), aspirin, digoxin, atracurium, tubocurarine, theophylline, amphotericin B, antibiotics, succinylcholine, tubocurarine and some other medicine can be harmful if combined with the dosage of Furosemide.

  • Monitoring during Lasix intake

The vet should always monitor blood sugar levels and kidney values before prescribing doses of Lasix. He must check upon the tolerance of your dog to the medicine to prevent adverse effects. He should check electrolyte balance by performing a renal panel to check electrolyte levels and ensure positive responses to Lasix.

Urination during sleep is a prevalent side effect of Lasix dosage.

To counter the excessive loss of water and salts, try to feed your dog with a mineral-rich diet and lots of water.

  • Increase in blood sugar

The vet should not recommend Lasix to dogs who are diabetic patients. Lasix results in an increase in blood sugar levels which can worsen blood pressure in dogs with diabetes.

Excessive potassium loss can cause weakness or lethargic behaviour along with fainting. If you find your dog significantly low on energy, contact the vet soon.

Moreover, you should take your dog immediately to the vet if conditions worsen, and he struggles to breathe. Lasix is a potent medicine but isn’t the only treatment to such heart diseases.
