Pharmacological properties

ATCvet QP53, ectoparasiticides, insecticides and repellents 

Pharmacological properties of the collar are due to the properties of the active ingredient. Fenthion is a thiophosphororganic insecticide; its mechanism of action involves blocking the acetylcholinesterase enzyme in the neural synapses of a parasite, resulting in its death. Fenthion poorly penetrates the blood-brain barrier of warm-blooded animals. 

The active ingredient, which is a component of the collar, is gradually released from the surface of the tape onto the animal's hair, acting as acaricide, insecticide and ovocide.  

The collar is well tolerated by animals, has no local irritative, skin-resorptive and sensitizing effect.

Directions for use

Prevention and treatment of dogs in ectoparasitic infestations: fleas (Ctenocephalides canis, Pulex irritans), lice (Linognathus setosus), biting lice (Ttrichodectes canis) and mites (Otodectes canis, Demodex canis).


The collar is removed from the package and put on the neck of the animal, being fixed in such a way that there is a space of 2-3 cm between the neck and the collar, then secured with a buckle, and the excess is cut off. 

The collar shall sit loose on the neck and not restrain the growth of the animal. When fit properly, the collar in a secured position shall move loosely around the neck. 


Do not use on sick, exhausted and weakened animals!

Do not use on animals with known hypersensitivity to fenthion!
