Vectra Felis is a veterinary medicine that contains two active substances: dinotefuran and pyriproxyfen. It is available as a
What is Vectra Felis used for?
Vectra Felis is used on cats to treat and prevent flea infestations. Its actions last for one month, and it prevents fleas from hatching and developing for three months. It may also be used as part of a treatment strategy for flea allergy dermatitis (an allergic reaction to flea bites).
The content of one full Vectra Felis applicator is applied directly to the cat’s skin, after parting its fur, at the base of the cat’s head. The responsible veterinarian should assess the need for repeat treatment and the appropriate time interval.
How does Vectra Felis work?
The active substances in Vectra Felis act as ectoparasiticides. This means that they kill parasites that live on the skin or in the fur of animals, such as fleas and ticks that feed on the animal’s skin.
Dinotefuran is an insecticide which kills insects by acting on receptors called nicotinic acetylcholine receptors in their nervous system. Pyriproxyfen is an insect growth regulator which stops the flea life
cycle by causing production of infertile eggs as well as by blocking the development of juvenile flea stages into adults.
How has Vectra Felis been studied?
The effectiveness of Vectra Felis against fleas was investigated in a large number of laboratory studies and in one field study.
The field study involved 129 cats with flea infestations that were treated once a month for three consecutive months either with Vectra Felis or with another
