Suspension for Injection.

An oily white/off-white suspension.

Cattle, Pigs

Procaine penicillin G is specifically formulated to provide sustained antibacterial activity following a single administration.

Ultrapen LA is indicated for use in cattle and pigs in the treatment and control of a wide range of common systemic, respiratory, urinary and local infections caused by or associated with organisms sensitive to penicillin, including Arcanobacterium pyogenes, Erysipelothrix rhusiopathiae, Mannheimia haemolytica, Pasteurella multocida and Streptococcus spp.

Ultrapen LA will therefore be effective in the treatment of infections, caused by susceptible organisms including:

Erysipelas; navel/joint-ill; respiratory tract infections, including pneumonia and atrophic rhinitis; meningitis; septicaemia; urogenital tract infections and the control of secondary bacterial invaders in diseases primarily of viral origin.

Ultrapen LA is contraindicated in known cases of hypersensitivity to penicillins.

Do not inject intravenously or by the intrathecal route.

Not to be used on very small herbivores such as guinea pigs, gerbils and hamsters.

None.

Shake the vial before use. This product does not contain an antimicrobial preservative. Swab the septum before removing each dose. Use a dry sterile needle and syringe.

Take care to avoid accidental injection. Wash hands after use.

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.

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 with breathing are more serious symptoms and require urgent medical attention.

Occasionally in suckling and fattening pigs administration of penicillin may cause a transient pyrexia, vomiting, shivering, listlessness and incoordination. Additionally in pregnant sows and gilts a vulval discharge which could be associated with abortion has been reported.

Although Ultrapen LA is well tolerated, occasionally a slight local reaction of a transient nature may be observed.

Ultrapen LA is safe for use during pregnancy and lactation.

In pregnant sows and gilts a vulval discharge which could be associated with abortion has been reported.

It is inadvisable to use other antibiotics concurrently.

Ultrapen LA is indicated for intramuscular and subcutaneous administration to non-lactating cattle and for intramuscular administration to pigs and lactating cattle.

The recommended dose rate is 20 mg procaine penicillin/kg bodyweight equivalent to 1 ml per 15 kg bodyweight. If signs persist at 72 hours repeat the dose.

Penicillins have a very wide safety margin.

Animals must not be slaughtered for human consumption during treatment.

Cattle may be slaughtered for human consumption only after 13 days from the last treatment.

Animals must not be slaughtered for human consumption during treatment.

Cattle may be slaughtered for human consumption only after 23 days from the last treatment.

Pigs may be slaughtered for human consumption only after 10 days from the last treatment.

Milk for human consumption must not be taken during treatment.

Milk for human consumption may only be taken from treated cows after 132 hours from the last treatment.

Pharmacotherapeutic group: Antibiotic

ATC Vet Code: QJ01CE09

Penicillin G is a beta-lactam antibiotic and its structure contains the beta-lactam ring and thiazolidine ring common to all penicillins.

Penicillin G shows excellent activity against susceptible Gram-positive bacteria such as Streptococci, Corynebacterium, Erysipelothrix and Clostridia but has limited activity against Gram-negative bacteria with the exception of the more fastidious Gram-negative aerobes such as Pasteurella spp.

Beta-lactam antibiotics prevent the bacterial cell wall from forming by interfering with the final stage of peptidoglycan synthesis. They inhibit the activity of transpeptidase enzymes, which catalyse cross-linkage of the glycopeptide polymer units that form the cell wall. They exert a bactericidal action but cause lysis only of growing cells.

After injection of Ultrapen LA, the procaine penicillin is rapidly absorbed from the site of injection with maximum penicillin levels of approximately 3.9μg/ml obtained in under 4.5 hours of subcutaneous injection in cattle, 1.3μg/ml obtained in under 4 hours of intramuscular injection in cattle and 2.1 μg/ml obtained in under 3 hours of intramuscular injection in pigs.

The penicillin elimination half-lives are approximately 16 hours for cattle and 7.5 hours for pigs following intramuscular injection and 8.5 hours for cattle following subcutaneous injection.

None Known.
