Diuretic dosage for cats and method of application

The veterinarian is responsible for developing the dosage regimen and calculating the daily dose. When determining the dosage, the etiology of the disease, the weight of the animal and the presence of complications are taken into account.

The daily dose of the tablet product for cats is 5-6 mg per 1 kg of body weight (solution - 0.5-06 ml per 10 kg of weight). For dogs, the norm increases to 8-10 mg per 1 kg of body weight (solution - 0.7-1 ml per 10 kg of weight). Depending on the severity of the disease and the intensity of the development of swelling, the dosage may be doubled.

The Furosemide treatment regimen involves a single dose of the drug 30-40 minutes before meals.

During research, the effect of the active substance on pregnancy has not been thoroughly studied, but it is known that the drug overcomes the placental barrier and can have a negative effect on the fetus. Therefore, experts do not recommend using the drug at this stage of life.

The drug is prescribed only when absolutely necessary in the second half of pregnancy.

Pregnant cats should only be prescribed the drug as a last resort.

It is not recommended to give this drug to an animal during lactation. The active component has the ability to suppress the milk production process. In addition, breast milk contains a small concentration of Furosemide, which can negatively affect the health of the offspring.

Furosemide for cats

: 08 Nov 2014, 17:38

Diuretics for animals are mainly used for edema and kidney disease in pets. Less commonly, diuretics are prescribed to animals in cases where it is necessary to remove poisons and toxins from the body, for example, after poisoning.

When choosing which diuretic to use to treat animals, veterinarians usually focus on Purine derivatives and such drugs as:

1. Temisal;
2. Eufillin;
3. Mercuzal;
4. Potassium acetate;
5. Juniper berries;
6. Bearberry leaf;
7. Hexamethylenetetramine.

Temisal is produced in the form of a white powder, highly soluble in water, which has not only a diuretic, but also a vasodilator and antispasmodic effect. The same can be said about Eufillin . The difference between the two drugs is minimal, since they are both derivatives of Purine.

Both drugs are used to treat dogs, pigs, small and cattle with intoxication complicated by weakened heart function, dropsy, edema of renal and cardiac origin, as well as congestion caused by heart failure. Temislan is prescribed orally three times a day at a dosage of 5/10 g for cattle and horses, 0.5/2 for pigs and small cattle, 0.25/0.1 for dogs.

Diuretic for a dog

The same drugs can be used as a diuretic for dogs as for farm animals, but in a much lower dosage, as well as hexamethylenetetramine , bearberry leaf, juniper berries and other medicinal herbs used to treat humans.

Natural diuretics for dogs can be purchased in the form of ready-made mixtures at veterinary pharmacies or you can prepare them yourself.

At the same time, due to the fact that in the gastrointestinal tract of dogs there are no enzymes that extract useful substances from a mixture of plants, herbal preparations must be prepared on the basis of aqueous extracts from coarsely ground raw materials.

Simply put, take a glass of boiling water, throw in 1 tablespoon of the raw material, leave for an hour, filter and add to drinking water. If bitter herbs, such as wormwood, are used as raw materials, then the infusion is added to food.

The approximate daily dosage of herbal remedies for dogs is calculated based on the weight of the pet:

• 36+ kg – 30ml;
• 23/36kg – 25ml;
• 9/23kg – 20ml;
• 0/9kg – 15ml.

Diuretic for cats

Diuretics for cats are usually prescribed for problems with urination. Urinary retention occurs especially often in castrated cats, as a sign of an inflammatory process in the body.

You can understand that your pet has a delay and it is necessary to give a diuretic to the cat by changing its behavior: cats begin to sit on the tray for a long time, behave restlessly, meow, spin around on the tray, often sit on it, but do not defecate or urine will appear in the tray. drops.

And although problems often arise due to an inflammatory process in the urethra caused by hypothermia or poor nutrition, choosing a diuretic for your cat on your own is not recommended.

If the problem is in the kidneys themselves or the inflammation is severe, then urine, having accumulated in the cat’s body, will lead to intoxication.

Regular use of diuretics for cats for preventive purposes is also not recommended, as this will lead to impaired kidney function.

All prescriptions must be made by a doctor. Independent replacement of synthetic diuretics for cats with herbal infusions is also fraught with consequences, since natural substances are significantly inferior in their effectiveness to modern diuretics, such as Diacard, Furosemide solution 1%, Veroshpiron 25 mg.

Furosemide is a diuretic drug from the category of loop diuretics. It can be used to treat dogs and cats

Furosemide: features and indications for use

Furosemide belongs to the category of loop diuretics - drugs that disrupt the absorption mechanism of chlorine and sodium ions without directly affecting kidney function.

It is based on an active substance with the same name (furosemide), which, after entering the body, is transformed into the substance glucuropide and is excreted from the body naturally.

In addition to the active ingredient, the product contains additional chemical compounds and ingredients that improve the absorption of the drug.

The main therapeutic effect of Furosemide is the prevention of fluid accumulation in soft tissues, due to which it can be used for the following diseases:

• arterial hypertension;
• kidney dysfunction;
• cirrhosis of the liver;
• oncological diseases;
• severe poisoning and intoxication;

For reference! Other names for furosemide are Lasix and Salix, that is, these drugs are its complete analogues and can replace each other in treatment.

Combination diuretics

Indications for use

Furosemide causes dilation of the veins, thereby reducing the filling pressure of the left ventricle of the heart, as well as the pulmonary artery. Veterinarians identify the following diseases for which Furosemide is used :

• Swelling of the kidneys, heart and brain.
• Chronic and acute renal failure.
• Liver diseases, including cirrhosis.
• High blood pressure.
• Heart failure.
• For intoxication and poisoning.
• For all diseases that cause swelling.

Dosage and method of administration

It is used orally and intramuscularly. Furosemide is prescribed to a cat by a veterinarian after examining the cat. Furosemide is mainly used in the following dosages :

• Intramuscular or intravenous (5% solution) - Furosemide injections for cats are given at the rate of 0.1 ml per 1 kg of body weight. Administer 1-2 times a day depending on the degree of the disease.
• Orally - The daily dose for oral administration is 5-6 mg per 1 kg of cat weight. Give by mouth, diluted with water, strictly before meals.

Note. If necessary, the dose may be increased as prescribed by the doctor. The maximum course of treatment is 10 days. With prolonged use, adverse effects are possible. If during this time Furosemide does not help, then it is changed to another drug. During treatment, the cat needs increased attention and proper care.

Furosemide - instructions for use for cats

Typically, diuretics are prescribed to felines in emergencies (pulmonary edema, traumatic conditions) or for chronic diseases. If the animal is treated on an outpatient basis, that is, at home, you can give it Furosemide in tablets. This method is less painful for the pet, but requires some skill from the owner.

There are different ways to force a cat to eat a pill, and the easiest option is to mix the crushed medicine into water. But in most cases, this method is not suitable, since Furosemide has an unpleasant taste (bitter). Therefore, you will have to fix the animal’s head, lower the lower jaw and put the medicine as deep as possible - on the root of the tongue. As a result, the cat will swallow the tablet reflexively.

For cats, the dosage of the drug is calculated according to body weight. For oral use, that is, inside, the recommended amount of medication is 2-4 mg per 1 kg of weight. For example, if your pet weighs 4 kilograms, then a standard 40 mg tablet should be divided into 2 or 3 parts. If the animal is very small, the calculation should be extremely accurate: for a kitten, the dosage should be several times less than for an adult.

When giving your cat pills, you need to take into account how they are absorbed. The active ingredient of the drug is poorly absorbed on a full stomach, so the medication is taken on an empty stomach. It is best to do this in the morning, before the first feeding. What dose of Furosemide can be given to a cat per day? Usually the indicated amount (2-4 mg/kg) is given once a day, but if there is no positive result, it is permissible to double the daily dosage for the cat, dividing it into two doses with an interval of 5-6 hours.

The tablets act fairly quickly, but in emergency situations it is advisable to use the injection form. For a cat with pulmonary edema, an injection is given into a muscle or vein. In this case, you also need to pre-calculate the amount of the drug. The dosage required for a cat is 2-4 mg/kg body weight, and for veterinary and “human” Furosemide, the volume of the drug in the syringe will be different:

• A 1% solution in ampoules contains 10 mg of the active substance in 1 ml (that is, a cat weighing 4 kg needs to be administered 0.4 ml of the medicine);
• The 5% veterinary product is more concentrated, so less solution is required - no more than 0.1 ml per kg of body weight.

Duration of action of Furosemide

In case of edema, Furosemide will cure a cat quickly, but only if all the doctor’s instructions are followed. Depending on the method of application, the speed of action of the medicine varies. When taking the tablet, the onset of action is within 15-30 minutes, and the effect lasts 6-8 hours.

When administered intramuscularly, the effect begins within 5-10 minutes, and the result is observed within 1.5-2 hours. Injections work much faster than tablets, but only a doctor determines what type of procedure a cat needs.

Contraindications

The main guide to restrictions is the instructions for use of Furosemide. The same contraindications are provided for cats and cats as for people :

• Lactation period. Furosemide can pass through the cat's milk to the kittens, and may also reduce milk production.
• Liver failure with anuria.
• Urolithiasis disease.
• Individual intolerance to components.
• Reduced potassium levels in the blood.
• Violation of water-salt metabolism.
• Violation of acid-base balance.
• Acute glomerulonephritis (kidney disease).
• Hypertrophic cardiomyopathy.

Side effects

In some cases, the following reactions are possible:

• General weakness and nausea.
• Disorder of the gastrointestinal tract.
• In cats, imbalance and other vestibular phenomena are possible.

It is important to understand that if any of the side effects occur, you should stop taking Furosemide and consult a veterinarian. These reactions may mean that the drug is not suitable for the cat, and its use may lead to undesirable results and worsen the course of the disease.

annotation

Diuretics have been widely used in cardiology since the middle of the last century. Their action is based on increasing the excretion of sodium and water from the body. This is necessary in the fight against edema due to heart disease.

In veterinary cardiology, five main groups of diuretics are used: thiazide, loop, potassium-sparing, osmotic diuretics and carbonic anhydrase inhibitors.

In the treatment of dogs and cats with heart failure and signs of edema, combinations of loop or thiazide diuretics with potassium-sparing drugs are recommended, and always with the use of ACE inhibitors.

Spironolactone as an aldosterone antagonist is recommended for use in heart failure of functional class 2 or more. Carbonic anhydrase inhibitors are recommended only as adjuvant therapy to enhance the effectiveness of loop and thiazide diuretics. Osmotic diuretics are of little use in cardiology. They are used in neurology and resuscitation.
