Instructions for use of Comfortis flea tablets for cats and dogs

Description of the drug

Comfortis tablets for dogs are used to kill blood-sucking insects on pets. A fast-acting over-the-counter remedy. The active substance is quickly absorbed into the blood, killing more than 90% of blood-sucking parasites within 4 hours.

Absorption of the substance is 70% and increases if the medicine is administered with food. The active substance undergoes extensive metabolism and is excreted in the feces. Treatment can begin at any time of the year, but it is preferable to begin treatment in early February before fleas become active.

The active ingredient (spinosad) is obtained by fermentation of the soil actinomycete bacterium Saccharopolyspora spinosa. The substance causes paralysis and death of fleas before they can lay eggs. Available in dosages from 90 to 1620 mg, which is convenient for treating different breeds of dogs.

Composition and expiration date

The preventative is a tan or dark brown chewable tablet for oral use for adult dogs depending on weight. Spinosad destroys only adult fleas and is eliminated from the body within a day.

Reviews from cat owners about the use of flea tablets

The tablets are mixed into food, and thanks to the flavoring, the animal eats everything calmly.
Reviews indicate that some owners consider it correct to give Comfortis half an hour before or after meals. Dosage - 50-100 mg/kg body weight. The dose cannot be exceeded. If no results are observed, subsequent use is possible after a month. It is given to dogs in the same way as to cats. The dosage is 40-50 mg/kg body weight. The drug should be stored in tightly closed packaging, at a temperature of 5 to 30 degrees, away from animals and children, as well as food and feed. Shelf life: 3 years. After the expiration date, its use is strictly prohibited.

In general, the tablets are well tolerated. Very rarely, individual intolerance to the drug may occur. After taking it, animals need to be monitored to eliminate the risk of possible complications. The instructions contain the following side effects: vomiting, weakness, loss of appetite.

The tablets are given with food. Mix into the dish. Basically, there are no difficulties with this. Comfortis contains food additives and flavorings that pets like. They smell like beef. Some owners prefer to give the drug in its pure form 20–30 minutes before or after meals.

Indicated for getting rid of fleas, preventing the appearance of various flea infections.

Dogs are given the drug in the same way. Only the dosage changes. For 1 kg of animal weight, 50–40 mg of the drug.

Flea tablets, the instructions for use of which recommend calculating the dose depending on the weight of the cat, are produced in various dosages. For ease of use, tablets that smell like beef are added to food. If the cat does not eat the medicine, you can repeat the dose. The effectiveness of the drug lasts up to 1 month. Repeated admission is allowed only after this period has expired.

The dose for a cat is prescribed at the rate of 50-100 milligrams of the active substance per 1 kilogram of body weight. It is not recommended to exceed the dosage indicated in the instructions to avoid the risk of side effects.

In dogs, an overdose of the drug causes nausea and vomiting.

Long-term studies of the properties of the insecticide have proven that it does not have a mutagenic or carcinogenic effect on the body. The active substance of the drug Comfortis is fat-soluble and therefore can accumulate in milk and adipose tissue.

Many cat owners are often faced with the problem of choosing an antiparasitic agent. How to choose the right flea drug and what criteria should be followed?

Basic criteria for choosing an anti-flea drug:

• high efficiency not only against mature individuals, but also larvae;
• long lasting result;
• low degree of toxicity;
• Possibility of use by kittens, pregnant and lactating cats;
• affordable price;
• ease of use;
• minimal risk of adverse reactions;
• availability on the shelves of domestic veterinary pharmacies and pet stores;
• low degree of absorption (absorption, dissolution) of the drug into the pet’s bloodstream.

The following dosage forms of antiparasitic drugs can be found on the veterinary drug market:

• drops on the withers;
• collars;
• sprays for external use;
• solutions for injections;
• shampoos;
• external powders;
• oral tablets.

When using insecticidal preparations, it is necessary to follow the rules of personal hygiene and safety precautions. After finishing working with the medicine, you should wash your hands thoroughly with soap.

For people with individual intolerance to the components of the veterinary drug, it is best to use sterile gloves. If adverse reactions occur, you should consult a doctor.

Empty boxes, blisters, and bottles of veterinary medications must be disposed of along with the trash. They cannot be used for household purposes.

Judging by the reviews on the forums, we can say that flea tablets are not the drug of choice for most cat owners. The majority prefer topical medications. But if we talk about tablet forms, the leading position is occupied by the American insecticidal drug Comfortis.

Flea tablets are a new step in the development of veterinary medicine. Their use is permissible even for dermatitis and lesions of the skin of animals. But at the same time, tablet forms of drugs have a number of contraindications, which the veterinarian takes into account when prescribing treatment. As practice shows, most cat owners prefer local antiparasitic agents.

Frontline was recommended to me by an experienced breeder in our city. I didn’t even know that such pills existed before. But I was convinced that it was enough to feed my pet one pill, and the problem with blood-sucking parasites would be solved. I also doubted for a long time that I could force the dog to eat the pill. As it turns out, it contains meat flavorings.

Natalia

I have been breeding dogs for many years. I pay close attention to protecting my pets from various parasites and bloodsuckers. When I was faced with the problem of fleas, I actively began to look for remedies. I came to the conclusion that the best medicine is Simparic tablets. I got rid of the parasites quickly enough. Now I use the drug for preventive purposes. It reliably protects my pets not only from lice, but also from various mites.

I believe the main advantage of these tablets is their high effectiveness. Within a few hours, if bloodsuckers live in the dog’s fur, they will be destroyed. In this case, the animals do not require any special treatment. The dogs will lead their usual lifestyle, unaware that treatment has already begun. I am very pleased with the effectiveness of these tablets. I continue to recommend them to my friends.

Once I had to try the drug Bravecto. A veterinarian I knew recommended him to me. He said this is an innovative product that not only kills many parasites, but also prevents them from clinging to the dog's skin again. After taking the tablet, I noticed that there were no fleas left in the fur at all.

Now, on the advice of the same veterinarian, I give these tablets to my pet for preventive purposes. Since I live near a forest, I often walk through it with my dog. Naturally, reliable protection against fleas and ticks is a must for me. I always have this drug on hand. It's a pity that this hasn't been invented for people yet.

I heard about Comfortis tablets relatively recently. I often communicate on various Internet forums dedicated to pets. There I learned that there are special tablets for dogs that quickly kill fleas and ticks. I tried it, and indeed, the bloodsuckers disappeared within a few hours.

We also pay special attention to the safety of these tablets. Despite their high efficiency and long-lasting residual effect, they do not harm the health of your four-legged friend. And in the future I will always use these tablets. I recommend them to my friends whose pets also experience fleas and various ticks.

Comfortis tablets should be given to your cat with food. The drug is mixed into food. Unlike other tablets, which can be difficult for a cat to eat due to the unpleasant odor, Comfortis contains flavorings and food additives, so there should be no problems with this.

This drug can get rid of fleas, can be used to prevent the appearance of parasites, and can also help with various flea infections.

Analogs

Pet stores offer similar flea products:

1. Nitenpyram is an expensive medicine (from 3,600 rubles per pack). Kills ticks and fleas quickly enough to reduce disease transmission.
2. Bravecto is a high-quality drug, without dangerous side effects. One of the disadvantages is the high cost of the tablets.
3. Frontline Nexgard is an individually packaged product that is well suited for small breeds.
4. Afoxolaner is easy to use, has no side effects, and is suitable for lactating bitches.
5. Capstar – high quality at low cost. Kills 95% of fleas within 5-6 hours after taking the capsule.

Choosing medication for your dog on your own without the supervision of a veterinarian is always risky, and in some cases can lead to ineffective treatment. Comfortis contains a specially developed dosage of substances for cats and dogs, so it is difficult to call medications from other manufacturers a valid analogue.

Contraindications

Treatment with this drug is contraindicated in puppies and pregnant females. Cannot be used on young animals under 4 months of age. The drug is contraindicated if the animal is undergoing treatment with tetracycline antibiotics. This may increase side effects.
