None.

Special precautions for safe use in the target species
Due to the likely variability (time, geographical) in the occurrence of metronidazole
resistant bacteria, bacteriological sampling and susceptibility testing are
recommended.
Whenever possible, the veterinary medicinal product should only be used based on
susceptibility testing.
Official, national and regional antimicrobial policies should be taken into account
when the veterinary medicinal product is used.
In very rare cases, neurological signs may occur especially after prolonged treatment
with metronidazole.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Metronidazole has confirmed mutagenic and genotoxic properties in laboratory
animals as well as in humans. Metronidazole is a confirmed carcinogen in laboratory
animals and has possible carcinogenic effects in humans. However, there is
inadequate evidence in humans for the carcinogenicity of metronidazole.
Metronidazole may be harmful for the unborn child.
Personal protective equipment consisting of impervious gloves should be worn when
handling the veterinary medicinal product.
To avoid accidental ingestion, particularly by a child, unused part-tablets should be
returned to the open blister space, inserted back into the outer packaging and kept in
a safe place out of the sight and reach of children. In case of accidental ingestion,
seek medical advice immediately and show the package leaflet or the label to the
physician. Wash hands thoroughly after handling the tablets.
Metronidazole may cause hypersensitivity reactions. People with known
hypersensitivity to metronidazole should avoid contact with the veterinary medicinal
product.
Special precaution for the protection of the environment:
Not applicable.

Metronidazole may have an inhibitory effect on the degradation of other drugs in the
liver, such as phenytoin, cyclosporine and warfarin.
Cimetidine may decrease the hepatic metabolism of metronidazole resulting in
increased serum concentration of metronidazole.
Phenobarbital may increase hepatic metabolism of metronidazole resulting in
decreased serum concentration of metronidazole.

Return any divided tablet to the blister and store protected from light.
