Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

immediate and persistent tick killing activity for at least 5 weeks.
For the treatment of flea infestations (Ctenocephalides felis and Ctenocephalides
canis
activity against new infestations for at least 5 weeks. The veterinary medicinal

Revised: February 2024
AN: 03227/2022
For the treatment of ear mite infestations (Otodectes cynotis).
For the treatment of demodicosis (Demodex canis).
For reduction of the risk of infection with Babesia canis canis via transmission by
Dermacentor reticulatus for 28 days after treatment. The effect is indirect due to the
activity of the veterinary medicinal product against the vector.
Fleas and ticks must attach to the host and commence feeding in order to be
exposed to the active substance.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Dogs:
Very rare
(<1 animal / 10,000 animals treated,
including isolated reports):
gastrointestinal signs (such as vomiting,
diarrhoea)
systemic disorders (such as lethargy,
anorexia)
neurological signs (such as tremor,
ataxia, convulsions)
1
Mild and transient.
In most cases these signs are transient.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
Transmission of B. canis canis cannot be completely excluded since D. reticulatus
ticks have to attach to the host before being killed. As an acaricidal effect against D.
reticulatus may take up to 48 hours, transmission of B. canis canis during the first 48
hours cannot be excluded.
The use of the veterinary medicinal product should be based on the local
epidemiological situation including knowledge of the prevalent tick species as
transmission of B. canis by tick species other than D. reticulatus is possible and
should be part of an integrated control program to prevent the transmission of
Babesia canis.

Special precautions for use in animals
In the absence of available data, treatment of puppies less than 8 weeks of age
and/or dogs less than 1.3 kg bodyweight should be based on a benefit-risk
assessment by the responsible veterinarian.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Wash hands after handling the veterinary medicinal product.
The accidental ingestion of the veterinary medicinal product may potentially result in
adverse effects, such as transient excitatory neurological signs. To prevent children
from accessing the veterinary medicinal product, only one chewable tablet at a time
should be removed from the blister pack and only when required. The blister pack
should then be returned into the carton immediately after use and the carton should
be stored out of the sight and reach of children. In case of accidental ingestion, seek
medical advice immediately and show the package leaflet or the label to the
physician.
