Comfortis - flea and tick tablets for dogs and cats

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.

Pharmacological properties

The drug is a broad-spectrum insecticide. Spinosad is a product of the activity of microscopic soil microorganisms. Microorganisms produce a substance that is dangerous to insects. The product is dangerous for all insects. It has a main effect on the nervous system, causing overexcitation, tremors, spasms, paralysis and death of the insect in insects. It is used against blood-sucking insects that parasitize domestic animals.

The active substances enter the pet’s blood through the gastrointestinal tract. Suction time - 30 minutes. The maximum concentration in the blood occurs after 48 hours. In this case, fleas, consuming blood with the drug dissolved in it, begin to die after 4 hours. The components of the drug remain in the blood for a long time. Almost complete removal of the active substance from the animal’s body occurs after 168 hours.

“Comfortis” is very convenient for destroying not only active ectoparasites, but also those that hatch from eggs during these 168 hours. The active substance is removed from the body along with feces. It is not addictive and does not develop flea resistance to the active substance.

Did you know? Fleas have even adapted to the climatic conditions of Antarctica. They are found in bird nests.

Review:

I keep several dogs at home because... I'm interested in hunting. Fleas were a real problem for me because bathing several large dogs with medicated shampoo is a real pain! Moreover, all animals have different temperaments; some cannot stand still while washing. Imagine my relief when I found out about flea tablets. Since then I have only used Comfortis, a very effective remedy!

Nikolay, Krasnoyarsk

Review:

I learned about Comfortis from a veterinarian when I brought him a kitten after being poisoned with flea drops. He said that the product is safe, does not cause allergies, only in very rare cases and is quickly eliminated from the body. We started using flea tablets constantly because... We always keep several cats and dogs at home.

Valentina, Mirny

Relief of unpleasant symptoms in pets occurs within the first 24 hours

What is the effectiveness of the drug

The fact is that the active substance - spinosad, as well as the taste of the drug, make it possible for complete absorption. Once ingested with food, the tablets quickly spread throughout the circulatory system. The insects that feed on it die from exposure to the poison.

The best drug, I tried everything, shampoos and sprays - nonsense, after a couple of months everything came back. I have many cats, one of them appeared, and immediately switched to all of them. It was “Comfortis” that became my salvation, everyone immediately started eating, and the fleas were gone. The drug is, of course, expensive, but super effective. Marina, owner of Mitchell

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.
