Emergency treatment of anticoagulant rodenticide poisoning, before starting oral
treatment..
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Dogs:
Undetermined frequency:Hypersensitivity reactions (anaphylactic-
type reactions)
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 also the
last section of the package leaflet for contact details.
As the anticoagulant effects of rodenticides are known to be long lasting it is
recommended to start vitamin K1 supplementation with an oral formulation within
12 hours of the last injection for a duration of 3 weeks, and to evaluate the
coagulation status (via one stage prothrombin times) 48 hours after the last
administration. In the case of persistence of the anticoagulant in the body, the
duration of treatment can be extended as long as the anticoagulant persists, to
avoid relapse (the coagulation status has to be evaluated 48 hours after each
attempt of treatment cessation).

i) Special precautions for use in animals
Administer by slow intravenous injection.
The formation of prothrombin may be inadequate when dealing with patients with
severe liver dysfunction. Therefore requires a careful monitoring of coagulation
parameters after administration of vitamin K1
ii) Special precautions to be taken by the person administering the veterinary
medicinal product to animals
People with known hypersensitivity to phytomenadione should avoid contact with
the veterinary medicinal product.
Avoid contact with eye. In the event of accidental contact with eye, rinse
immediately and thoroughly with tap water, then seek a doctor and show the label
to the physician.
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.
Salicylates (NSAID) and cephalosporins presenting the N-methyl-thiotetrazole
moiety may reduce the effect of vitamin K1, by inhibition of the vitamin K1
recycling.
Store below 25°C. Protect from light.

should be discarded.
