Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a
veterinarian, to either the marketing authorisation holder or its local
representative or the national competent authority via the national reporting
system. See the package leaflet for contact details.

None.

Special precautions for use in animals
For the 250 mL pack, the use of a multidose syringe is recommended. To refill
the syringe, the use of a draw off needle is recommended to avoid excessive
broaching of the stopper.
It is recommended to use the veterinary medicinal product in the early stages of
disease and to evaluate the response to treatment within 72 hours. Resistance
against oxytetracycline may vary. Use of the veterinary medicinal product should
be based on susceptibility testing and taking into account official and local
antimicrobial policies.
Inappropriate use of the veterinary medicinal product may increase the
prevalence of bacteria resistant to oxytetracycline and may decrease the
effectiveness of treatment with tetracyclines due to the potential for cross
resistance.
Because oxytetracycline can retard foetal skeletal development and may cause
discoloration and enamel hypoplasia of foetal teeth, the veterinary medicinal
product should be used cautiously in the last half of pregnancy.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
People with known hypersensitivity to tetracyclines should avoid contact with
the veterinary medicinal product.
The direct or indirect contact of the user via skin or mucosa should be avoided
because of the risk of sensitisation. Wash hands after use. In case of contact with
eyes or skin, wash immediately with water as irritation may occur.
Laboratory studies in rabbits and rats conducted with the excipient N-methyl
pyrrolidone have shown evidence of foetotoxic effects. Women of childbearing
age, pregnant women or women suspected of being pregnant should use the
veterinary medicinal product with serious caution to avoid accidental self-
injection.
Special precautions for the protection of the environment
Not applicable.
Other precautions
Not applicable.

Oxytetracycline should not be administered simultaneously with penicillins or
cephalosporins.

Do not freeze. Keep the container in the outer carton.
