Product information

What is Furosemide used for in pets?

Furosemide, also known by its generic name Lasix, is a prescription medication that can treat several medical conditions in pets. It is most commonly prescribed for oedema (fluid retention) associated with congestive heart failure, renal disease and other illnesses such as glomerulonephritis. Furosemide works by blocking sodium and chloride reabsorption in the kidneys, promoting diuresis or increased urination. This helps to reduce the amount of fluid retained in the body. In cats, Furosemide treats hypertension (high blood pressure) associated with hyperthyroidism and certain types of heart disease.

It is important to note that Furosemide should only be given to pets under the supervision of a veterinarian.

Can dogs and cats take humans Furosemide?

Furosemide is generally considered safe for use in both dogs and cats. However, only give Furosemide to your pet after a veterinarian has prescribed it. Never give your pet human medication unless you have consulted with a vet first.

What is the dosage of Furosemide for dogs and cats?

The dosage of Furosemide for dogs and cats varies depending on the size, weight and severity of the medical condition being treated. Your veterinarian will prescribe the correct dose for your pet and provide specific administration instructions. It is important to follow dosing instructions carefully, as giving too much or too little of the medication can lead to health complications.

How do I give my pet Furosemide?

Furosemide is usually given orally as a pill or liquid solution. Make sure you give your pet the medicine with plenty of water and that they do not crush, break or chew the pills. If your pet is having difficulty swallowing its medication, it can be mixed with food or dissolved in a small amount of water.

What are the side effects of Furosemide in pets?

The side effects of Furosemide in pets can include increased urination, diarrhoea, and constipation. In some cases, the medication may also cause potassium depletion, leading to muscle weakness or other medical issues. If your pet experiences any of these symptoms following the administration of Furosemide, contact your veterinarian as soon as possible. Monitor your pet closely for any changes in behaviour or appetite.

Where can I buy Furosemide for my cat or dog?

You can buy Furosemide from online pharmacies (such as HealthExpress) with a prescription from your pet's veterinarian. You can also get Furosemide directly from the veterinarian clinic or a high street pharmacy. However, the price of Furosemide may be higher in one of those places.

How do I place an order for Furosemide for my pet at HealthExpress?

You're already in the right place. Head to the top of the page and select the required dose and quantity. This information should be found on the prescription from the vet. Once you have confirmed the delivery method and completed the payment, you will receive instructions on how to send us your pet's prescription so we can send you your pet's treatment.

How much is Furosemide for pets?

The cost of Furosemide for pets can vary depending on the formulation, dosage strength and quantity needed. As Amoxicillin is a medicine used to treat humans as well, you can typically get it for a better price if you buy it from a pharmacy than if you get it from the vet. Online pharmacies advertise their prices, and you typically won't find it cheaper than from an online provider, such as HealthExpress. Additionally, some pet insurance providers may cover the cost of certain medications. Always do your research before making a purchase.
