Special precautions for safe use in the target species:
Chlortetracycline must be used cautiously in patients with renal insufficiency or
hepatic impairment.
Use of the product should be based on identification and susceptibility testing of the
target pathogens. If this is not possible, therapy should be based on epidemiological
information and knowledge of susceptibility of the target pathogens at farm level, or
at local/regional level.
Inappropriate use of the product may increase the prevalence of bacteria resistant to
chlortetracycline and may decrease the effectiveness of treatment with related
substances, due to the potential for cross-resistance
Use of the product should be in accordance with official, national and regional
antimicrobial policies.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Chlortetracycline may cause hypersensitivity reactions.
People with known hypersensitivity to tetracyclines should avoid skin contact and
inhalation of dust particles during preparation and administration of the medicated
drinking water.
Do not eat, drink or smoke while handling the product or medicated drinking water.
Personal protective equipment consisting of protective overall, glasses, impermeable
gloves (e.g. rubber or latex) and an appropriate dust mask (e.g. disposable half
mask respirator conforming to European Standard EN149 or a non-disposable
respirator to European Standard EN140 with a filter to EN143) should be worn when
handling the veterinary medicinal product.
Wash hands immediately after handling the product or medicated drinking water. In
the event of skin or eye contact, rinse immediately the affected area with large
amounts of clean water. Seek medical attention if irritation occurs/persists. If you
develop symptoms following exposure to the product such as skin rash, you should
seek medical advice and show the label or package leaflet to the physician. Swelling
of the face, lips or eyes or difficulty with breathing are more serious symptoms and

AN: 01369/2023 & 01372/2023
Special precautions for the protection of the environment:
The veterinary medicinal product may be toxic to plants. In order to prevent any
adverse effects on terrestrial plants, manure must not be spread onto land without
dilution with manure from untreated animals. Manure should be diluted with at least
the same weight of manure from untreated animals.
After dilution, storage and composting can significantly reduce the active ingredient
content. The rate of excretion of chlortetracycline in urine and faeces varies
between species. Spreading manure from animals treated on different areas of land
each year can prevent accumulation of the active substance in the soil. manure
made from the deep litter of domestic fowls can be used after proper storage.
Absorption of chlortetracycline from the alimentary tract is reduced by calcium, iron,
magnesium and zinc salts.
This veterinary medicinal product does not require any special temperature storage
conditions.
Store in a dry place.
