i. Special Precautions for use in animals
Do not dilute the product.
If concurrent treatment is administered, use a separate injection site.
Resistance against oxytetracycline may vary. Use of the product should be
based on susceptibility testing and taking into account official and local
antimicrobial policies.
Inappropriate use of the 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.
ii. Special precautions to be taken by the person administering the
veterinary medicinal product to animals
This product may cause hypersensitivity reactions (allergy). Persons with a
known hypersensitivity to tetracyclines should not handle this product. Wash
hands after use. In case of contact with eyes or skin, wash immediately
with plenty of water as irritation may occur.
Take care to avoid accidental injection.
Oxytetracycline may interfere with the action of bactericidal antimicrobials, such
as penicillins and cephalosporins, and therefore they should not be used
simultaneously.
Concomitant vaccination is not recommended because of possible immuno-
suppressive activity of tetracyclines.
Do not store above 25ºC. Protect from light.
Following withdrawal of the first dose, use the product within 28 days.
Discard unused material
When the vial has been broached and contents exposed to air, the solution
