Target species
Cattle, Horses, Sheep, Pigs
Indications for use, specifying the target species
For the treatment of systemic infections in cattle, horses, sheep and pigs caused by or associated with organisms sensitive to penicillin and/or streptomycin including:
Arcanobacterium pyogenes
Erysipelothrix rhusiopathiae
Klebsiella pneumoniae
Listeria spp
Mannheimia haemolytica
Pasteurella multocida
Staphylococcus spp (non-penicillinase producing)
Streptococcus spp
Salmonella spp
and for the control of secondary bacterial infection with sensitive organisms in diseases primarily associated with viral infection.
Contraindications
Contraindicated in known cases of hypersensitivity to penicillins.
Special Warnings for Each Target Species
Use with care in animals known to have kidney disease or defective renal function.
Do not exceed the recommended dosage or duration of treatment.
Special Precautions for Use
Special precautions for use in animals:
Care should be taken not to exceed the recommended dosage. Aminoglycosides have a narrower margin of safety than beta lactam antibiotics.
Special precautions to be taken by the person administering the product to the 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 reaction to these substances may occasionally be serious.
•Do not handle this product if you know you are sensitised, or if you have been advised not to work with such preparations.
•Handle this product with great care to avoid exposure taking all recommended precautions.
•If you develop symptoms following exposure, such as a skin rash, you should seek medical advice and show the doctor this warning. Swelling of the face, lips or eyes or difficulty in breathing are more serious symptoms and require urgent medical attention.
Wash hands after use.
Adverse reactions (frequency and seriousness)
In rare cases, hypersensitivity reactions can occur and very rarely, these can be fatal. Very rarely, in sucking and fattening pigs, administration may cause a transient pyrexia, vomiting, shivering, listlessness and incoordination. A palpable but transient local reaction may occur at the site of intramuscular administration in horses.
The frequency of adverse reactions is defined using the following convention:
•very common (more than 1 in 10 animals displaying adverse reactions during the course of one treatment)
•common (more than 1 but less than 10 animals in 100 animals)
•uncommon (more than 1 but less than 10 animals in 1,000 animals)
•rare (more than 1 but less than 10 animals in 10,000 animals)
•very rare (less than 1 animal in 10,000 animals, including isolated reports).
Use during pregnancy, lactation or lay
Pen & Strep can be safely administered to pregnant and lactating animals. However in pregnant sows and gilts a vulval discharge which could be associated with abortion has been reported.
Interactions with other medicinal products and other forms of interaction
Do not administer with other antibiotics such as tetracyclines or with other aminoglycosides.
Amount to be administered and administration route
