Pharmacology

Advantage is a topical/”spot-on” insecticide medication for the control of lice and fleas. Its active ingredient is the parasiticide imidacloprid. Its mode of action interferes with the transmission of impulses in the nerve system of insects.

Imidacloprid will kill both the adult and the larval stage of flea. Upon application imidacloprid spreads over the body with the body oils collecting in hair follicles where it is released over time (up to 1 month) onto the skin. It will remain on even if the rat is bathed, although it will diminish with each subsequent bath.

Imidacloprid is not appreciably absorbed into the body, and although it is reported to have a wide margin of safety some animals may develop hypersensitivity.

Studies indicate that imidacloprid is not teratogenic. However it is reportedly not recommended for use in pregnant animals, nor should it be used on rats younger than 5 weeks old.

Indications

Used to treat lice (on rats) and flea infestation.

Drug Interactions or Contraindications

Do not allow to be taken internally or apply to eyes.

Do not use in combination with other insecticides.
