Special precautions for use in animals
Due to the likely variability (time, geographical) in the occurrence of metronidazole
resistant bacteria, bacteriological sampling and susceptibility testing are
recommended.
Whenever possible, the 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.
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 thus may have carcinogenic effects in humans as well. However, there
is inadequate evidence in humans for the carcinogenicity of metronidazole.
The product can cause skin sensitisation. In case of known hypersensitivity to
metronidazole or other nitroimidazole derivatives or one of the components of the
product, avoid contact with the veterinary medicinal product.
Avoid contact with the skin or mucous membranes including hand-to-mouth contact.
To avoid such contact wear impervious gloves when handling the product and/or for
direct administration into the animal's mouth.
Do not allow treated dogs to lick persons immediately after intake of the medication.
Wash hands after use.
In case of skin contact, wash thoroughly the affected area.
Metronidazole may cause adverse (neurological) effects.
Avoid accidental ingestion.
Do not drink, eat or smoke when administering the product.
Close the bottle immediately after use to avoid the child gaining access to the
contents. Do not leave a syringe containing solution in the sight or reach of children.
In order to prevent children from getting access to used syringes, keep the syringes
in the original packaging after use.
In case of accidental ingestion, seek-medical advice immediately and show the
package leaflet or the label to physician.
Additional warnings when administering the product into the feed:
Avoid the access of children to the dog’s medicated food. In order to prevent children
from getting access to the dog’s medicated food, pour it over a part of the feed and
wait until the animal has completely consumed the medicated feed, then administer
the rest of the feed. Give the treatment out of the sight and reach of children. Any
uneaten medicated food must be removed immediately and the bowl washed
thoroughly; wear gloves and wash hands when handling the product and cleaning the
contaminated food bowl.
