40mg Libeo Tablets For Dogs - per Tablet
782038
40mg Libeo is a prescription-only chewable tablet for dogs. Each tablet contains 40mg of furosemide, a diuretic (water tablet) that helps the body remove excess fluid. Libeo is used to treat oedema (fluid in tissues) and ascites (fluid in the abdomen), particularly when these problems are linked to cardiac insufficiency or congestive heart failure in dogs. Your veterinary surgeon will decide whether Libeo is suitable and will prescribe a dose for your dog’s weight and clinical needs.
Heart failure means your dog's heart is not pumping as effectively as it should. When circulation becomes less efficient, pressure can rise in blood vessels and the body can activate hormone systems that conserve salt and water. The aim is to support circulation, but the side effect can be fluid retention. Extra fluid can then leak from blood vessels and collect in places where it causes symptoms. Fluid may build up in the lungs (leading to coughing or fast, effortful breathing), in the abdomen (ascites), or in tissues (oedema). Reducing this excess fluid can ease breathing, improve comfort, and help dogs tolerate gentle activity.
How 40mg Libeo works
Furosemide is a loop diuretic. It acts in the kidneys, where it reduces the reabsorption of sodium and chloride. Water follows salt, so more water stays in the urine and is passed out of the body. As urine output increases, the volume of fluid in the bloodstream falls. This helps reduce congestion and encourages excess fluid in the lungs, abdomen, or tissues to move back into the circulation so it can be removed. Because furosemide affects salt and water balance, it can also alter electrolytes such as potassium and sodium, so dosing and monitoring matter.
When Libeo may be prescribed
Libeo is commonly used when a dog has signs of fluid retention linked to heart disease. Your vet may prescribe it if your dog has abdominal fluid, visible swelling, or congestion affecting breathing. Libeo is often used alongside other heart medicines, such as pimobendan and ACE inhibitors, depending on the type and stage of heart disease. In some dogs, Libeo is used short term to bring fluid under control. In other dogs, it forms part of longer-term management, with the dose reviewed over time.

Description
40mg Libeo for Dogs
Libeo may only be supplied with a valid veterinary prescription issued by your vet. You should only purchase Libeo if you have or are in the process of arranging such a prescription. See information bar for further details.
How to give 40mg Libeo
Libeo is given by mouth. The tablets are chewable and may be administered directly into the mouth or mixed with a small amount of food offered before the main meal. The tablets can be divided into equal quarters, which helps with dose accuracy when smaller adjustments are needed. Always give the amount and frequency prescribed, and do not change the plan without veterinary advice.
Many dogs urinate more after a dose. If your dog is on a once-daily schedule, your vet may recommend giving it earlier in the day so your dog has more chances to toilet. If your dog needs twice-daily dosing, the timing will be set to balance symptom control with practicality.
Your vet will tailor the dose to your dog. Libeo doses are calculated in milligrams per kilogram of body weight and may be given once daily or split into two daily doses. Some dogs need a higher dose at the start of treatment, with the dose reduced once symptoms are stable. The general aim is to use the lowest effective dose that keeps fluid controlled while minimising dehydration and electrolyte imbalance. If signs of fluid retention return, your vet may adjust the dose or add other medicines.
Increased thirst and increased urination are expected and usually indicate that the medicine is having its intended effect. Some dogs need more frequent walks or garden breaks, especially in the first days of treatment or after a dose increase. As congestion improves, your dog may breathe more comfortably and abdominal swelling can reduce as ascites improves.
If your dog seems very weak, stops eating, vomits repeatedly, has diarrhoea, becomes unsteady, or you notice a sudden worsening of breathing, contact your vet promptly. These signs can indicate dehydration, electrolyte disturbance, progression of heart failure, or another problem that needs assessment.
Monitoring and follow-up
Dogs taking diuretics often need follow-up checks. Your vet may monitor hydration, body weight, kidney values and electrolytes, particularly when treatment is started or the dose is changed. At home, it can help to track resting breathing rate (when your dog is asleep or relaxed), appetite, water intake, and toileting patterns. Sudden changes can be a useful early warning that the treatment plan needs reviewing.
Possible side effects
The most common effects are increased urination and thirst. Some dogs may develop dehydration or electrolyte imbalances, particularly at higher doses or if they are unwell. Signs may include lethargy, weakness, reduced appetite, vomiting, diarrhoea, increased panting, or changes in coordination. If you notice these signs, contact your vet, as the dose may need adjustment and your dog may need blood tests. Accidental ingestion of extra tablets should be treated as urgent, because overdose can cause serious water and electrolyte disturbances.
When Libeo may not be suitable
Libeo should not be used in dogs with dehydration, low blood pressure, or low circulating blood volume. It should not be used in renal failure where the dog is not producing urine, or in dogs with significant electrolyte deficiency. It should also not be used in dogs with known hypersensitivity to furosemide, sulfonamides, or any tablet ingredient. Your vet may use caution in dogs with impaired liver function or diabetes mellitus, and will take into account the full medical history before prescribing.
Tell your vet about all medicines and supplements your dog receives, including anti-inflammatories and any over-the-counter products. Some combinations can increase the risk of kidney strain or electrolyte changes, while others may reduce the diuretic effect. Your vet will consider this when setting the overall heart failure treatment plan and may recommend closer monitoring after medication changes.
Store Libeo in its original packaging, in a cool, dry place, and out of reach of children and pets. Because the tablets are flavoured, dogs may try to eat them if they are left accessible. Only give Libeo to the dog it was prescribed for, and only as directed by your veterinary surgeon.
How does Libeo help with oedema and ascites in heart failure?
In heart failure, the body can retain salt and water, which then collects in the lungs, abdomen or tissues. Libeo contains furosemide, a diuretic that makes the kidneys pass more sodium and water into the urine. This reduces the volume of fluid in the circulation and helps fluid reabsorb from affected areas.
How quickly will Libeo start to work?
Many dogs pass more urine and drink more water within a few hours of a dose. Improvement in breathing comfort or abdominal swelling can be seen the same day, although response varies with the cause and severity of the heart disease. Your vet may adjust the dose over several days to find the lowest effective amount.
Can I give 40mg Libeo with food?
Yes. Libeo tablets are chewable and may be given directly by mouth or mixed with a small amount of food offered before the main meal. Giving it earlier in the day often helps reduce night-time urination. Always follow your vet’s dosing instructions and do not change the schedule without advice.
What if I miss a dose of Libeo?
Give the missed dose as soon as you remember, unless it is nearly time for the next dose. If you are close to the next scheduled dose, skip the missed one and continue as normal. Do not give two doses at once. If you miss more than one dose or symptoms worsen, contact your vet promptly.
Should I restrict my dog’s drinking water while on Libeo?
Do not restrict water unless your vet specifically instructs you to. Most dogs on furosemide will drink more because they are urinating more. In some situations, your vet may advise keeping water intake within normal limits, but this needs individual guidance to avoid dehydration, especially in older dogs or those with kidney disease.

5mg Fortekor Flavour Tablet - per Tablet
5mg Fortekor Flavoured is a heart failure treatment for dogs. It contains the active ingredient benazepril hydrochloride.
Fortekor 5mg is given orally and is broken down into an efficient inhibitor of angiotensin-converting enzyme (ACE), reducing blood volume, sodium and water levels, as well as making it harder for your dog's heart to pump effectively.
VET PRESCRIPTION REQUIRED
2.5mg Fortekor Palatable Tablet for Cats and Dogs - per Tablet
2.5mg Fortekor Flavour is a veterinary medication formulated for the treatment of heart failure in dogs and chronic renal insufficiency in cats. The active ingredient in Fortekor, benazepril, is an angiotensin-converting enzyme (ACE) inhibitor that plays a vital role in managing these health conditions. With its flavoured formulation, Fortekor makes it easier for pet owners to administer the medication to their pets, ensuring better compliance and more effective treatment outcomes.
Fortekor's primary action comes from its active ingredient, benazepril, which functions as an ACE inhibitor. In cases of heart failure in dogs, Fortekor helps improve blood flow by preventing the constriction of blood vessels, thus enhancing the heart's efficiency in pumping blood throughout the body. This ultimately results in a reduction of symptoms associated with heart failure, such as fatigue, shortness of breath, and fluid retention, improving the dog's overall quality of life.

Vetmedin 5mg Flavour Tablet - per Tablet
Vetmedin 5mg is a prescription heart medicine for dogs with congestive heart failure, when the heart can no longer pump blood efficiently enough to meet the body’s demands. Vetmedin contains pimobendan, which is commonly used for heart failure linked to degenerative mitral valve disease (a leaky mitral valve) and dilated cardiomyopathy (a weakened, stretched heart muscle). The aim of Vetmedin 5mg is to reduce the workload on the heart and improve circulation so your dog can breathe more comfortably, move with less fatigue, and enjoy normal routines again.
Vetmedinis iss an “inodilator”, meaning it helps the heart squeeze more effectively (a positive inotrope) and also relaxes blood vessels (a vasodilator). This means that Vetmedin 5mg helps the heart pump with more strength and makes it easier for blood to flow forwards, so the heart does not have to work as hard to circulate oxygen and nutrients. It supports contraction partly by helping the heart muscle use calcium more efficiently, which can improve pump strength without relying on a harsh “stimulant” effect, and it also helps widen blood vessels by affecting an enzyme pathway called phosphodiesterase‑3 (PDE3). The combined effect can improve cardiac output, reduce congestion, and support better oxygen delivery to the tissues, which is why many dogs seem brighter and more willing to be active once they stabilise.
5mg/40mg Cardalis Tablet for Dogs - per tablet
5mg/40mg Cardalis Tablets for Dogs
Cardalis 5mg/40mg is a prescription-only tablet used as part of the management of congestive heart failure in dogs. Each tablet contains two active ingredients: benazepril (5mg) and spironolactone (40mg). They work in different but complementary ways to reduce strain on the heart and help control the fluid and pressure changes that can occur with heart failure.
Congestive heart failure in dogs
Congestive heart failure (CHF) describes a stage of heart disease where the heart can no longer pump efficiently enough to meet the body’s needs. When the heart struggles, pressure can build up in blood vessels and the body activates hormone systems that attempt to maintain circulation. These responses can cause the body to retain salt and water and can make blood vessels tighten. Over time, this can lead to fluid accumulation, commonly in the lungs, and it can increase the workload of the heart.
Dogs with CHF may show coughing, faster or more laboured breathing, reduced stamina, restless sleep, reduced appetite, or swelling in the abdomen. Symptoms can vary depending on the underlying heart problem and on where fluid builds up. CHF is a condition that requires ongoing veterinary care, and treatment is usually long term.
How Cardalis works
Cardalis combines an ACE inhibitor (benazepril) with an aldosterone antagonist (spironolactone). Together, they target two key pathways that are often overactive in CHF.
Benazepril works by reducing the production of angiotensin II, a substance that narrows blood vessels and encourages salt and water retention. By reducing angiotensin II, blood vessels can relax and blood pressure can reduce. This can lower the resistance the heart has to pump against, which may improve forward blood flow and reduce congestion. Benazepril can also help limit signals that contribute to fluid retention.
Spironolactone works by blocking the effects of aldosterone. Aldosterone is a hormone that tells the body to hold on to sodium and water. In CHF, aldosterone can remain high and can continue to drive fluid retention. By antagonising aldosterone, spironolactone helps reduce sodium and water retention while conserving potassium. Aldosterone can also influence longer-term changes in the heart and blood vessels, so controlling its effects can be valuable alongside other heart medicines.

10mg Libeo Tablets For Dogs - per Tablet
10mg Libeo is a chewable furosemide tablet for dogs. Furosemide is a "loop diuretic", which means it encourages the kidneys to pass more salt and water into the urine. In dogs with heart failure, this diuretic effect helps reduce the excess fluid that can collect in the lungs, abdomen, or other tissues. Libeo is authorised for the treatment of ascites and oedema, particularly when these signs are associated with cardiac insufficiency.
When the heart is not pumping efficiently, pressure can rise in the blood vessels that return blood to the heart. Fluid can then seep out of the circulation and into body tissues. Pulmonary congestion or pulmonary oedema can occur when fluid accumulates in or around the lungs, and breathing can become more difficult. Pleural effusion can occur when fluid collects around the lungs and limits their expansion. Ascites can occur when fluid collects in the abdomen and causes visible distension. Peripheral oedema can appear as swelling in the limbs or under the skin.
Not every dog with heart disease develops fluid build-up, but when it occurs it is a common reason for sudden worsening of symptoms. Many dogs require long-term treatment and regular monitoring, because the dose often needs adjustment as the disease changes over time.
How 10mg Libeo works
Furosemide acts mainly in a part of the kidney called the loop of Henle. It reduces the reabsorption of sodium and chloride, and water follows these salts into the urine. As urine output increases, the amount of fluid circulating in the bloodstream falls. This reduction in circulating volume can lower venous pressure and reduce the “back-pressure” that drives fluid into the lungs or abdomen.
