Yuri, 40 years old, Omsk:

“I've had pets all my life and tried all sorts of flea treatments. Pet insecticide was recommended by a veterinarian as a treatment and preventive measure. It really works, no side effects identified.”

Veterinarians

Svetlana, veterinarian, 45 years old, Moscow:

“The insecticide is used for control and complex treatment of fleas in pets. Comfortis is well tolerated by animals and is suitable for pregnant and lactating bitches. If the pet has a severe infestation, a repeat dose is required 14 days after the first dose.”

Oleg, veterinarian, 27 years old, Saratov:

“Tableted capsules containing the active ingredient spinosad destroy 99% of parasites. The drug is used for cats and dogs to combat aphanipterosis. The effect of the medicine is noticeable 45-50 minutes after absorption.”

Precautionary measures

• It is prohibited to use Comfortis for dogs with epilepsy;
• The drug is contraindicated in pregnant and lactating females (the drug penetrates into milk and colostrum);
• Do not use on animals under 14 weeks of age;
• If an animal has an individual intolerance to the drug, manifested in nausea, vomiting, weakness, it is necessary to consult a doctor;
• The drug should be stored away from pets and small children;

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.

Sofia, Perm

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.

Side effects from use

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.

Comfortis against fleas is a high-quality and effective product. In a matter of hours, the pet will be saved from parasites, because fleas cause great harm to the animal, deplete its body and suck out all the beneficial substances. Death may result. There is no need to save on pets, as they say: “We are responsible for those we have tamed!” Anna, owner of three cats

Indications for use

Comfortis is indicated for the prevention and treatment of aphanipterosis (flea infestation) and ticks for cats and dogs. Used once, shortly before, during or after a meal. Re-appointment is carried out no earlier than a month later, even if the parasites appear earlier.

If pets live together, they should be treated with flea and tick tablets at the same time so that fleas do not spread from the treated animal to the rest. It is also recommended to disinfect areas where the animal is kept using special means.

Important! If timely treatment is not carried out, your pet may develop an allergic reaction or dermatitis. Small breed dogs and young cats may suffer from anemia. Fleas facilitate the penetration of tapeworms and infect tularemia and typhoid fever.

Who are ticks and why are they dangerous?

Ticks are one of the oldest groups of terrestrial invertebrates that belong to the phylum arthropods, the class of arachnids. Today there are more than 54 thousand species. Representatives of the orders acariform and parasitiform mites are of the most important veterinary importance, and we will consider them.

Acariform mites

As a rule, mites of this order have a microscopic structure, among which there are species that cause severe dermatological diseases.

Sarcoptes canis

An intradermal parasite in dogs that parasitizes and multiplies in the epidermal layer of the skin and is the causative agent of canine sarcoptic mange. In common parlance, this disease is called “scabies,” which is associated with the manifestation of the main clinical sign - severe itching. In the dog, on the affected areas, most often the skin in the ears, muzzle, elbows and hock joints, you can notice areas of alopecia, bleeding scratches, and scales. The skin becomes thickened and hyperemic. To confirm the diagnosis, microscopy of skin scrapings is necessary.

Otodectes cynotis

This is the causative agent of the disease otodectosis of carnivores, parasitizing the auricle in the external auditory canal. Sick animals constantly experience itching: they itch their ears against objects or scratch them with their claws. You may notice your pet sitting with its head lowered or tilted to the side. In advanced forms, there is a discharge of purulent-ichorous exudate from the auricle. The disease is diagnosed based on clinical signs and detection of mites in skin scrapings.

Demodex canis

It is the causative agent of demodicosis in dogs. This mite parasitizes hair follicles and sebaceous glands. There are scaly, nodular, pustular and mixed forms of demodicosis. Each form is characterized by its own specific manifestation of the disease, but the general symptoms are: the formation of alopecia and small nodules with a diameter of 1-2 mm in the affected areas, accompanied by severe itching. Diagnosis is made based on clinical findings and microscopic examination of skin scrapings.

Parasitiform mites

This order includes the Ixodid tick family, which is widespread throughout the world. The most important are representatives of the genera Ixodes, Dermacentor and Rhipicephalus - carriers of the most dangerous blood-parasitic diseases.

Piroplasmosis (babesiosis) of dogs

A disease caused by microorganisms of the genus Babesia. The disease is transmitted by ticks D. reticulatus, R. sanguineus, I. ricinus. The latent period of the disease lasts from 2 to 20 days, after which the first symptoms begin to appear in the animal - fever, refusal of food and food, inactivity, later you can notice bloody urine and jaundice in the dog. If these symptoms do not immediately contact a veterinarian and begin treatment, this will be fraught with serious complications that will lead to death.

Canine monocytic ehrlichiosis

The disease is not common in Russia; it is mainly diagnosed in the southern regions of our country. The causative agent of the disease is E. canis; carriers are the same ticks. The incubation period is up to 20 days. Initially, the clinical symptoms are the same as in the case of piroplasmosis. In the absence of timely treatment, it leads to renal failure, glomerulonephritis, and arthritis.

Canine anaplasmosis

Caused by intracellular parasites of the Anaplasmatacea family that infect dog platelets. The course of the disease is almost completely similar to the previous ones, which makes it quite difficult to correctly diagnose without special diagnostic systems.

Lyme disease (borreliosis) in dogs

The causative agent of the disease is the bacterium Borrelia burgdorferi sensu lato. Vectors I. ricinus and I. persulcatus. In most dogs, the disease goes silent. The first clinical signs appear after 1-6 months, and are usually of a sad nature (anorexia, arthritis). Accurate diagnosis can also be obtained if the clinic has special test systems.

Side effects and contraindications

Any drug with an insecticidal effect sometimes has side effects. Comfortis is no exception.

There are contraindications

Despite good tolerability, after use the animal may experience the following on the first day:

• increased secretion of saliva;
• loss of appetite or complete refusal of food;
• vomit;
• diarrhea;
• oppression;
• ataxia.

If the above symptoms appear, you should take your pet to a veterinarian, who will prescribe therapy. Comfortis anti-tick and flea tablets are contraindicated for use in productive animals.

Important! If after the first use the animal begins to vomit, then the drug should be given again on the same day or consult a veterinarian about another treatment option for parasites.

It should not be used simultaneously with other anti-flea agents, so as not to cause severe poisoning. In combination with Doxorubin or Digoxin, spinosad can enhance their negative effects.

Recommendations for use

Before using the medicine, consult your veterinarian and inform the doctor:

• about chronic diseases that your pet suffers from;
• supplements or medications your dog takes;
• negative reactions that have occurred during flea treatment in the past.

Remember to give the tablets immediately after meals to avoid vomiting.
