An animal's reaction to animal medicine
You can report when a medicine may not have worked, or could have made your animal unwell.
You’ll be asked for details of:
- the medicine, including batch number and marketing authorisation number if known
- the animal that was affected, for example the species, breed and age
- when and how the medicine was first given to the animal
- the symptoms
