Parasites need to start feeding on the host to become exposed to lotilaner; therefore the
risk of the transmission of parasite borne diseases cannot be completely excluded.

i). Special precautions for use in animals
All safety and efficacy data have been acquired from dogs and puppies 8 weeks of age
and older and 1.3 kg of body weight and greater. Use of this veterinary medicinal product
in puppies younger than 8 weeks of age or less than 1.3 kg of body weight should be
based on a benefit-risk assessment by the responsible veterinarian.
ii). Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Wash hands after handling the product.
In case of accidental ingestion, seek medical advice immediately and show the package
leaflet or the label to the physician.
iii) Other precautions
Not applicable
None known.
During clinical testing, no interactions between Credelio chewable tablets and routinely
used veterinary medicinal products were observed.
This medicinal product does not require any special storage conditions.
Use an appropriate combination of available strengths to achieve the recommended dose
of 20– 43 mg/kg.
Credelio is a palatable chewable flavoured tablet. Administer the chewable tablet(s)
monthly with or after food.
For the treatment of demodicosis (caused by Demodex canis):
Monthly administration of the product for two consecutive months is efficacious and leads
to a marked improvement of clinical signs. Treatment should be continued until two
negative skin scrapings are obtained one month apart. Severe cases may require
prolonged monthly treatments. As demodicosis is a multi-factorial disease, where
possible, it is advisable to also treat any underlying disease appropriately.
