Advantage Spot On is a flea treatment containing the active ingredient Imidacloprid which is used to kill flea infestations and prevent reoccurring flea infestations in dogs, cats and rabbits.

Advantage Spot On also helps to treat biting lice in dogs.  

Advantage is available in packs of 4 pipettes and in 5 different strengths to treat different breeds and sizes of animal:

Advantage 40 – Small cat/ rabbit/ dog
Advantage 80 – Large cat/ rabbit
Advantage 100 – 4-10kg dog
Advantage 250 – 10-25kg dog
Advantage 400 – 25-40kg dog

Fleas will be killed within 1 day of the animal being treated with Advantage. It can prevent further flea infestations for up to 4 weeks in dogs, 3-4 weeks in cats, and 1 week in pet rabbits. Once these time frames have elapsed, the treatment will need to be repeated. It must not be applied more frequently than once a week.

If a veterinary surgeon has previously diagnosed your cat or dog as suffering from Flea Allergy Dermatitis, Advantage can be used as part of the treatment.
