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

antibodies.
The induction of such antibodies is uncommon and may have no effect or may result
in a decrease in efficacy in animals that responded to treatment previously.
If no or limited response is observed within one month after initial dosing, an
improvement in response may be observed after administration of a second dose

one month later. However, if the animal does not show a better response after the
second dose, the veterinary surgeon should consider alternative treatments.
i) Special precautions for use in animals
Where a dog has not been able to properly exercise prior to treatment due to its
clinical condition, it is recommended that the dog is gradually (over a few weeks)
allowed to increase the amount of exercise they take (to prevent overexercise by
some dogs).
Caution should be used when treating patients with the following pre-existing
conditions: immune-mediated haemolytic anaemia, immune-mediated polyarthritis,
immune-mediated thrombocytopenia.
Caution should be used when treating patients with pre-existing seizure disorder.
ii) Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Hypersensitivity reactions, including anaphylaxis, could potentially occur in the case
of accidental self-injection. Repeated self-administration may increase the risk of
hypersensitivity reactions.
The importance of nerve growth factor (NGF) in ensuring normal foetal nervous
system development is well-established and laboratory studies conducted on non-
human primates with human anti-NGF antibodies have shown evidence of
reproductive and developmental toxicity. Pregnant women, women trying to conceive
and breastfeeding women should take extreme care to avoid accidental self-injection.
In case of accidental self-injection, seek medical advice immediately and show the
package leaflet or the label to the physician.
Special precautions for the protection of the environment:
Not applicable.

osteoarthritis, this veterinary medicinal product had no adverse effect when

concomitantly administered with a non-steroidal anti-inflammatory product
(carprofen).
There are no safety data on the concurrent long-term use of NSAIDs and
bedinvetmab in dogs.
In clinical trials in humans, rapidly progressive osteoarthritis has been reported in
patients receiving humanised anti-NGF monoclonal antibody therapy. The incidence
of these events increased with high doses and in those human patients that received
long-term (more than 90 days) non-steroidal anti-inflammatory drugs (NSAIDs)
concomitantly with an anti-NGF monoclonal antibody.
Dogs have no reported equivalent of human rapidly progressive osteoarthritis.
No other laboratory studies on the safety of concomitant administration of this
veterinary medicinal product with other veterinary medicinal products have been
conducted. No interactions were observed in field studies where this veterinary
medicinal product was administered concomitantly with veterinary medicinal products
containing parasiticides, antimicrobials, topical antiseptics with or without
corticosteroids, antihistamines and vaccines.
If a vaccine(s) is to be administered at the same time as treatment with this veterinary
medicinal product, the vaccine(s) should be administered at a different site to that of
the veterinary medicinal products administration, to reduce any potential impact on
immunogenicity of the vaccine.
