treatment.
The requirement for long-term therapy should be based on an individual benefit-risk
assessment.
The tablets can be administered with or without food. However, it is recommended
that the veterinary medicinal product is administered in a consistent manner in
relation to feeding since its bioavailability is increased by administering the product
with food.
The dosing table below shows the number of tablets required. The tablets are
breakable along the score-line allowing them to be divided into equal halves, if
required.

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 the national competent authority via the
national reporting system. See the package leaflet for respective contact details.
None.

Special precautions for safe use in the target species:
Use of this veterinary medicinal product in dogs younger than 12 months of age is not
recommended and should be based on a benefit-risk assessment by the responsible
veterinary surgeon.
When dogs are to be administered long-term treatment, it is recommended that they
are re-weighed on a regular basis so that the dose can be adjusted accordingly in the
case of a significant change in bodyweight.
Use of the veterinary medicinal product has not been evaluated in dogs with hepatic
or renal disease. Use of the product in these sub-populations should be according to
a benefit:risk assessment by the responsible veterinary surgeon.
Ilunocitinib modulates the immune system and may increase susceptibility to
opportunistic infection and exacerbate neoplastic conditions. Dogs receiving the
veterinary medicinal product should therefore be monitored for the development of
infections and neoplasia.
The veterinary medicinal product may cause a decrease in leukocyte (monocyte,
eosinophil and neutrophil) counts and a reduction in red cell mass parameters (red
blood cell count, haemoglobin and haematocrit) when initiating treatment. These
changes typically remain within the laboratory reference range, stabilise within the first
month of treatment and do not appear to be clinically relevant. However, periodic
monitoring of complete blood counts and serum biochemistry is recommended when
dogs are on long-term treatment.
Use of the product in dogs with anaemia has not been evaluated and should be
according to a benefit:risk assessment by the responsible veterinary surgeon.
When treating pruritus associated with allergic dermatitis with ilunocitinib, investigate
and treat any underlying causes (e.g. flea allergic dermatitis, contact dermatitis, food
hypersensitivity). Furthermore, in cases of allergic dermatitis and atopic dermatitis, it
is recommended to investigate and treat complicating factors, such as bacterial, fungal
or parasitic infections/infestations (e.g. flea and mange).
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Accidental ingestion of the product may cause gastro-intestinal effects.
In case of accidental ingestion, seek medical advice immediately and show the
package leaflet or the label to the physician.
Wash hands after administration.
Special precautions for the protection of the environment:
Not applicable.
Based on adverse event reporting, no known drug interactions were observed under
field conditions following concomitant administration of ilunocitinib with other
veterinary medicinal products such as endo- and ectoparasiticides, antimicrobials,
vaccines or non-steroidal anti-inflammatories.
However, during these clinical trials no specific investigation of the potential for drug
interactions was conducted in animals receiving ilunocitinib with another veterinary
medicinal product concomitantly.
Concurrent administration with other drugs with potential immunosuppressive effects
(e.g. systemic glucocorticoids, cyclosporin A) must only be based on a benefit:risk
assessment by the responsible veterinary surgeon.
The effect of ilunocitinib administration concomitantly with vaccines has only been
evaluated in the laboratory using vaccines authorised in the USA. A similar serological
response to vaccination was seen in Beagle dogs administered the vaccine
concomitantly with ilunocitinib at 1x the recommended treatment dose (0.6-0.8 mg/kg
bodyweight) compared to dogs administered the vaccine alone. The clinical relevance
of these findings (correlate of protection) has not been established and infection
challenge studies have not been conducted. The decision on whether to administer
vaccines concomitantly with the veterinary medicinal product should be made
according to a benefit:risk assessment by the responsible veterinary surgeon.
Ilunocitinib is a substrate for the P-glycoprotein transporter. Co-treatment with other
drugs that are P-glycoprotein substrates, inhibitors or inducers could give rise to
pharmacokinetic drug interactions. The potential clinical consequences of such
interactions have not been investigated.
The use of gastric pH modifiers may affect the oral bioavailability of ilunocitinib.
Therefore, such products should be used with caution.
This veterinary medicinal product does not require any special storage conditions.
