This drug is recommended for use at the first signs of the disease, when its properties are most pronounced. The great advantage of fosprenil is that it can be used in the treatment of dogs of different ages.

, it does not have toxic or allergenic properties.

Fosprenil is produced in Russia; in addition to the official name, the drug has a non-proprietary international name: disodium salt of polyprenols phosphate. This is the main active ingredient of fosprenil, which has the ability to increase the bactericidal activity of blood serum and increase the body's resistance to viruses. In addition to disodium salt of polyprenols phosphate, the medicine contains water for injection, glycerin, ethanol and Tween-80.

Fosprenil is available in the form of an injection solution that has a clear or slightly yellowish color, without a pronounced odor or taste. The presence of any inclusions, sediment or flakes is not allowed. The solution is packaged in glass bottles with a capacity of 10 milliliters or bottles with a capacity of 50 milliliters.

When and how is Fosprenil used?

The veterinary remedy can be used both for the prevention and treatment of viral infections of domestic animals, in particular cats, rabbits and even birds. It relieves inflammation and speeds up recovery. In addition, Fosprenil increases immunity and protects tailed pets in contact with sick individuals.

Fosprenil can be used for the prevention and treatment of:

• plague;
• herpes;
• calcivirosis;
• viral rhinotracheitis and other viral infections;
• food poisoning.

The drug can be given simultaneously with antihistamines and antibiotics. However, it cannot be combined with hormones and steroids.

Fosprenil is mainly used for intramuscular injections (0.2 mg per 1 kg weight). Drops into the eyes and sometimes oral use are also allowed. The course of treatment is 7 days (in especially severe cases, it can be extended to 2 weeks).

When to use

The instructions indicate that Fosprenil is used for dogs with the following pathologies:

• plague of carnivores (distemper);
• infectious hepatitis;
• rhinotracheitis;
• infectious peritonitis;
• viral enteritis;
• viral adenoviruses;
• other infectious diseases.

A sterile solution can be given to pets in various ways:

• intramuscularly;
• subcutaneously;
• intravenously;
• orally.

Fosprenil can be used to wash the eyes and nose, but in this case it is diluted with clean water in a 1:1 ratio. To make the medication more effective, intramuscular injections are given. Preference is given to injections into a vein in severe cases of the disease to achieve maximum rapid effect.

Doses and treatment regimens

The dosage of Fosprenil for dogs is calculated taking into account the weight of the animal - 0.1 ml per 1 kg of weight. For severe pathologies, the dose is doubled. If it is necessary to administer a large volume of medication, it is recommended to do this in several places. When administered orally, the dose is doubled.

The treatment regimen may vary depending on the pathology:

1. If an animal is diagnosed with infectious peritonitis or plague and the disease is severe, the first two days the drug is administered 4 times a day (every 6 hours), then for a week - 3 times a day with an interval of 8 hours. Then two injections are given for two days and one for another two days. The regimen is followed even if the symptoms have disappeared.
2. In case of moderate severity of plague, as well as hepatitis, enteritis, on the first day the animal is given 4 injections with an interval of 6 hours. Then for a week the injections are given three times a day, then another two days with 2 injections and two days with 1.
3. If infectious diseases are mild, the animal is given three doses on the first day. On the second day, 2 doses with an interval of 12 hours are enough, on the third – 1 dose. The duration of treatment can be increased to 5-7 days depending on the condition of the pet.
4. For plague, the duration of treatment is at least 14 days, regardless of the condition of the animal.

Features of application

The treatment regimen can be changed by the doctor depending on the condition of the dog, the characteristics of the body and the symptoms present. To achieve the fastest possible therapeutic effect and avoid possible complications, Fosprenil is combined with antibacterial and antihistamine drugs, as well as drugs whose action is aimed at detoxification, restoration of water-salt balance and elimination of symptoms. To enhance the therapeutic effect, it is combined with interferon, but additional use of immunostimulating agents is usually not required.

To prevent infectious diseases, the medication is given to animals once. In this case, the dosage remains the same as during treatment. Preventive measures are carried out in the following cases:

• during epidemic outbreaks;
• when traveling to a region with a high danger threshold;
• upon contact with sick animals.

To enhance immunity during vaccination, the medicine is also administered once in the doses given above. For revaccination, the use of medication is not required. The drug is administered together with the vaccine, but in different places.

It is not recommended to skip taking the medicine. This inevitably leads to a decrease in its effectiveness. If a timely dose is missed, the dog should be given the medicine as soon as possible, and then return to the current treatment regimen.

Despite the fact that Fosprenil is considered a safe medicine, it should not be used without consulting a doctor. In addition, its use is most effective in complex treatment, which should only be prescribed by a veterinarian.

Fosprenil belongs to the category of immunomodulators and antiviral drugs.

Fosprenil for cats

Additionally, the composition has an anti-inflammatory effect and helps restore healthy intestinal microflora. The purpose of using the medicine is to activate natural processes in the body.

The veterinary drug enhances the activity of blood plasma and increases the rate of metabolic processes in cells.

With the use of the drug, the number of leukocytes in the blood and phagocytes increases, which allows the body to naturally destroy the pathogen.

Fosprenil prevents the development of complications and is not addictive. After discontinuation of the medication, there is no sharp decrease in immunity and no deterioration in the pet’s condition.

Pharmacology

Fosprenil stimulates the main parameters of the cat’s body that regulate body homeostasis:

• Increasing the body's natural resistance
• bactericidal activity of blood serum and phagocytosis
• Strengthening the humoral immune response in cats to vaccines, thereby increasing the body's specific resistance to infections
• Reduces the incidence of disease in kittens
• Activates metabolic processes in cells, tissues and organs
• Has minor antiviral activity against herpesviruses, orthomyxoviruses, paramyxoviruses, togaviruses, feline coronaviruses
• Minor hepatoprotective, cardioprotective, and antioxidant properties have been described

Indications for use

The composition is effective against coronavirus, herpesvirus, paramyxovirus, togavirus, and orthomoxovirus.

As a preventive measure, Fosprenil is prescribed to cats that have had contact with a sick animal.

In acute pathologies, the drug is used as an emergency aid, which in a short time allows to stop the progression of the disease.

As a preventive measure, the medicine is prescribed to cats that have had contact with a sick animal.

The main indications for the use of Fosprenil are:

• panleukopenia (distemper);
• rhinotracheitis – if it was caused by an infection;
• calcivirosis;
• infectious lesions of the abdominal cavity with severe manifestations of intoxication;
• viral lesions of the respiratory system;
• food poisoning - the drug is prescribed to relieve inflammation and intoxication.

Before vaccinations, cats may be advised to administer medication to boost the body's immune response. The measure is not always used.

Important! A veterinarian may prescribe a course of Fosprenil if a domestic cat has spent several days outside. The product is needed to prevent the development of the disease if there is a possibility that the animal has been infected with the virus.

Operating principle

The effect of the veterinary treatment and prophylactic drug Fosprenil on the dog’s body is to stimulate the basic parameters of the physiological resistance system

, increasing the bactericidal activity of blood plasma with a clear progression of the phagocytosis process, which leads to an increase in the humoral immune response of the animal’s body to the action of the vaccine.

The effect of the drug is targeted, increasing the body’s immunity and resistance to infection by infectious diseases.

due to accelerated cellular metabolism, due to which the incidence rate is sharply reduced.

According to GOST of the Russian Federation, Fosprenil is classified as “Low hazardous substances, hazard class IV”

and in recommended doses does not cause harm to the animal’s body.

The drug can be used as a prophylactic agent for the purpose of:

• relief of complications in the period after;

What is Fosprenil

Fosprenil is a natural antiviral drug (immunomodulator) that regulates the functioning of the immune system, relieves inflammation, prevents the development of pathogenic microflora in the gastrointestinal tract and prevents the harmful effects of toxins.

The drug is used as a prophylactic and therapeutic agent for viral infections of various etiologies.

In what cases is it advisable to use Fosprenil:

• food poisoning;
• infectious peritonitis, enteritis, colitis;
• upper and lower respiratory tract infections;
• gastrointestinal pathologies of unknown origin;
• viral infections (herpes, cat flu, calicivirus, distemper virus and others).

The drug significantly increases the body's resistance to coronaviruses, parvoviruses, orthomyxoviruses, adenoviruses and other pathogens of serious illnesses.

The drug is available in the form of an injection solution. Glass vials are sold in dosages from 2 to 100 ml. Fosprenil is intended for intramuscular or intravenous injection; it is also used to treat the external areas of the eyes and the mucous membranes of the nasal passages. The transparent substance has no color and does not contain mechanical impurities.

Important! The medicinal substance is not available in tablets. Dosage varies depending on the disease and the age of the pet.

It is recommended to consult a veterinarian before use.

Cost and analogues of Fosprenil

The cost of the drug is about 900 rubles per package, which contains 5 bottles of 10 ml each. You can usually buy them individually at veterinary hospitals. The cost of one 10 ml bottle will range from 100 to 150 rubles.

The main analogues of the drug are:

• Gamavit - the active substance in the composition is placental emulsion;
• Forvet – the basis of the product is the plant extract Panavir;
• Maxidin - the active ingredient is BPDH.

The possibility of using a Fosprenil analogue should be assessed by a veterinarian. The owner should not change the instructions without permission.

Advantages and disadvantages of the drug

The advantages of Fosprenil include several factors:

• accessibility (the medicine can be bought at almost any veterinary pharmacy);
• low price (from 140 rubles per 10 ml bottle);
• no contraindications (except allergies);
• low risk of side effects;
• Fosprenil does not contain toxic substances.

The disadvantage of this immunomodulator is its unproven effectiveness (or its low degree). There is currently no scientific evidence that the drug actually affects the course of treatment, for example, for viral infections. All conclusions about the drug are made only on the basis of the experience and practice of those people who used it. In addition, Fosprenil is most often used in combination with other medications, so even successful treatment may be due to them.

After talking with the seller from the nearest veterinary pharmacy, I came to the conclusion that Fosprenil may also have counterfeits. Of course, the pharmacist didn't tell me how to identify them. Only one thing is clear: you need to carefully study the packaging, and it is better to buy 10 ml bottles immediately in a box, and not individually. By the way, if the veterinary pharmacy did not offer you several different packaging options at once, then there is a great chance of buying real Fosprenil.

One of the disadvantages of Fosprenil is the likelihood of “running into” a fake

If you follow the instructions in the instructions during use, the absence of irritating, toxic and allergic effects from the drug on the walls of the intestines and stomach is guaranteed. Instructions for using Fosprenil for cats or dogs can be given by a veterinarian.

In what cases is it recommended to use Fosprenil for prevention?

The medicine can also be used as a preventative measure, for example, if your cat has been in contact with a sick animal for some time. To prevent the development of a viral infection after such contact, it is enough to inject the individual with 0.8 ml of the drug intramuscularly.

Another reason for preventive vaccinations is the cat being outdoors. If your pet goes on frequent walks, it is also recommended to give him such injections annually.

Immunocompromised cats often develop illnesses even when kept entirely indoors. Why is this happening? Such animals get infected from their owners' shoes or simply by walking on the balcony. In order to prevent such a situation, your pet can also be given a preventive vaccination, which will increase the immune system’s resistance to viral diseases.

Finally, another case where Fosprenil can be used is for sensitive events that involve visiting sensitive locations. If you and your pet often visit exhibitions where there are many other cats - potential carriers of infection, Fosprenil can become your faithful assistant.

Thus, Fosprenil is an effective antiviral drug that not only prevents the proliferation of pathogenic microorganisms, but also has a beneficial effect on the state of the immune system. Due to its attractive price and minimal side effects, this medication has been successfully used in veterinary medicine for many years to treat cats, regardless of their age and health condition. You can also try this solution on your pet, but before using it, it is recommended to consult an experienced veterinarian to determine the optimal dosage.

When using the product, strictly follow the instructions that come with the drug. It is better to consult a veterinarian before use.

For puppies

The drug can be prescribed to puppies, but the daily dosage will vary. Babies require medicine in a volume of 0.9-1.2 milliliters per kilogram of body weight. In this case, a single dose should be no more than 0.3 milliliters per kilogram.

According to the instructions for the drug, there are no age restrictions.

Fosprenil is used for the prevention and treatment of viral infections dangerous to dogs:

• carnivore plague,
• viral adenoveroses
• enteritis.

When treating such viral infections, a single dose for intramuscular administration is 0.1 ml per kilogram of body weight. The daily dose should not exceed 0.4 ml per kilogram of body weight. For moderate and severe clinical forms of viral infections that are life-threatening to the animal, a single dose for intramuscular administration can be more than doubled.

Oral administration of fosprenil to dogs is also possible. The dose should be doubled relative to intramuscular. The treatment regimen is chosen individually by the veterinarian, since it directly depends on the specific type of disease. Treatment with the drug is stopped two or three days after the main symptoms of the disease disappear and the general condition normalizes.

Then the drug is given for 3-6 days with a gradual reduction in dose. If the upper respiratory tract is affected as a result of the virus entering the body, it is better to instill fosprenil into the eyes and nose, diluting it 3 to 5 times with saline.

For relapse or treatment of chronic viral diseases, the daily dose is administered once every three days. For prophylactic purposes, fosprenil is used once every 3 days, 1 daily dose for 9 days. The drug is available in two doses.

Price

A 10 ml bottle costs about 180 rubles, and a 50 ml bottle can cost up to 800 rubles.

I breed Chihuahuas and the first two litters did not tolerate the first vaccination very well. Two kids even died. Therefore, the veterinarian prescribed us fosprenil to create an adequate immune response during vaccination. We administer it two days before vaccination and children are protected from over-reception of the vaccine.

How to give

Fosprinil can be administered to dogs:

• by ingestion (orally);
• by instillation (for example, for a runny nose, into the nose);
• intramuscular and intravenous injections.

A veterinarian must prescribe a treatment regimen for your dog.

To administer Fosprenil orally, you need to pull back part of your pet's lip and slowly pour the drug into the cheek. In this case, either a special introducer syringe or a disposable syringe without a needle is used. When taken orally, the single dose of Fosprenil is doubled.

If it is necessary to apply Fosprenil to the dog's eyes or nose, use a pipette washed in warm water. Fosprenil is diluted 3 times with saline and pipetted.

Then you need to pull back the lower eyelid with one hand and press the pipette cap with the other. It is necessary to bury it closer to the inner corner of the eye. Excess medication that comes out of the eye is wiped with a cotton swab or napkin.

An intramuscular injection (into the thigh or shoulder muscle) is given with a sterile syringe selected depending on the size of the dog and the dosage of the medication.

When carrying out medical procedures using Fosprenil, it is necessary to use:

1. medical gloves;
2. protective glasses;
3. respirator (mask).

Attention! To prevent infection, do not touch the syringe needle with your hands, and do not touch anything other than the dog’s skin with the needle!

How to give an injection?

Fosprenil must be warmed in your hands to 37 degrees and the syringe filled with the required dosage, making sure that no air gets into it.

You need to start administering the injection after making sure that the injection site is not inflamed or damaged and that the dog is relaxed. If the muscles are tense, you need to first calm the pet, for example, by massaging it. Skin treatment before injection is not required, since dogs are protected from the penetration of bacteria inside by a dense skin layer.

The injection for dogs up to 10 kg is made at a depth of 1-1.5 cm. For larger pets, the needle insertion depth increases to 3.5 cm. The syringe is positioned perpendicularly to better achieve the goal.

Important! When changing the needle, it is necessary to remove air from it. To do this, you need to press the piston before a drop appears from the needle hole.

The appearance of a small amount of blood after injecting a dog does not pose a threat. A 20-minute cold compress will help stop heavy bleeding. As a last resort, if the compress does not help, you should contact your veterinarian to prescribe hemostatic drugs.
