Why has my veterinarian prescribed this medicine?

Phytomenadione is used to treat animals that have been poisoned with warfarin or coumarin anticoagulants (e.g. certain rodenticides). These poisons may cause bleeding problems in the animal. This medication helps to stop bleeding. Phytomenadione may be used for other conditions as prescribed by your veterinary surgeon.

In Australia this is available as veterinary formulations therefore delete the following: Phytomenadione is not available as a veterinary preparation in the UK. Your veterinary surgeon may ask you to sign a consent form so a preparation licensed for humans can be used to treat your pet.
