Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.
The veterinary medicinal product has a persistent insecticidal efficacy for up to 5 weeks
against fleas (Ctenocephalides felis).
The veterinary medicinal product has a persistent acaricidal efficacy for up to 2 weeks
against ticks (Rhipicephalus sanguineus, Ixodes ricinus, Dermacentor reticulatus). If
ticks of some species (Rhipicephalus sanguineus and Ixodes ricinus) are present when
the product is applied, all the ticks may not be killed within the first 48 hours but they
may be killed within a week.
The veterinary medicinal product can be used as part of a treatment strategy for the
control of Flea Allergy Dermatitis (FAD) where this has been previously diagnosed by a
veterinary surgeon.
Method of administration:
Thermoformed pipettes:
Hold the pipette upright. Tap the narrow part of the pipette to ensure that the contents
are within the main body of the pipette. Break the snap-off top of the spot-on pipette
along the scored line.
Part the pet’s coat until its skin is visible. Place the tip of the pipette directly against the
bared skin and squeeze gently several times to empty its contents Repeat this
procedure at one or two different points along the cat’s back, preferably at the base of
the head and between the shoulders.
(Note : the shape of the marketed pipettes can be different as well as the pictures on
the marketed boxes/package leaflets.)
Polypropylene pipettes:
Remove the pipette from the blister packaging. Hold the pipette in an upright position,
twist and pull the cap off. Turn the cap around and place the other end of the cap back
on the pipette. Twist the cap to break the seal, then remove the cap from the pipette.
Part the pet’s coat until its skin is visible. Place the tip of the pipette directly against the
bared skin and squeeze gently several times to empty its contents. Repeat this
procedure at one or two points along the cat’s back, preferably at the base of the head
and between the shoulders.
It is important to make sure that the product is applied to an area where the animal
cannot lick it off, and to make sure that animals do not lick each other following
treatment.
Care should be taken to avoid excessive wetting of the hair with the product since this
will cause a sticky appearance of hairs at the treatment spot. However, should this
occur, it will disappear within 24 hours post application.
White deposits may also be seen at the site for up to 48 hours after application.
Treatment schedule:
For optimal control of flea and/or tick infestation the treatment schedule can be based
on the local epidemiological situation.
In the absence of safety studies, the minimum treatment interval is 4 weeks.

Reporting adverse events is important. It allows continuous safety monitoring of a

as carpets and soft furnishings which should be treated, in case of massive infestation
and at the beginning of the control measures, with a suitable insecticide and vacuumed
regularly.
The veterinary medicinal product does not prevent ticks from attaching to the animals. If
the animal has been treated prior to exposure to the ticks, the ticks will be killed in the
first 24-48 hours after attachment. This will usually be prior to engorgement, minimising
but not excluding the risk of transmission of diseases. Once dead, ticks will often drop
off the animal, but any remaining ticks may be removed with a gentle pull.
It is advisable to avoid frequent bathing or shampooing because the maintenance of
effectiveness of the veterinary medicinal product in these cases has not been tested.
When used as part of a strategy for the treatment of Flea Allergy Dermatitis, monthly
applications to the allergic patient and to other cats in the household are recommended.
For optimum control of flea problems in a multi-pet household, all dogs and cats in the
household should be treated with a suitable insecticide.

People with known hypersensitivity to fipronil or excipients should avoid contact with the
