Special precautions to be taken by the person administering the veterinary medicinal product to animals

Care should be taken to avoid accidental self-injection. In the case of accidental self-injection, seek medical advice immediately.

Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross-reactions to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

Dose volume is equivalent to 1 ml per 10 kg bodyweight. If dose volume exceeds 20 ml, it should be divided and injected into two sites. As with other injectable preparations normal aseptic precautions should be observed.

An appropriately graduated syringe must be used to allow accurate administration of the required dose volume. This is particularly important when injecting small volumes.

Overdose (symptoms, emergency procedures, antidotes), if necessary

Penicillins have a wide safety margin.

Withdrawal period

Milk for human consumption must not be taken from a cow during treatment. With cows milked twice daily, milk for human consumption may only be taken from 79 hours (i.e. at the 7th milking) after the last treatment. With other dosing routines, the basis of the veterinary surgeons advice should be that milk may be taken for human consumption only after the same period from the last treatment (i.e. with three times a day milking, milk for human consumption may only be taken at the 10th milking).

Cattle (meat): 23 days from the last treatment.

Sheep and pigs (meat): 16 days from the last treatment.

Not for use in sheep producing milk for human consumption.
