Description
The combination of penicillin G and dihydrostreptomycin acts additive and in some cases synergistic. Procaine penicillin G and benzathine penicillin G are small-spectrum penicillins with a bactericidal action against mainly Gram-positive bacteria like Clostridium, Corynebacterium, Erysipelothrix, Listeria, penicillinase-negative Staphylococcus and Streptococcus spp.
Dihydrostreptomycin is an aminoglycoside with a bactericidal action against mainly Gram-negative bacteria like E. coli, Campylobacter, Klebsiella, Haemophilus, Pasteurella and Salmonella spp.
Indications
Arthritis, mastitis and gastrointestinal, respiratory and urinary tract infections caused by penicillin and dihydrostreptomycin sensitive micro-organisms, like Campylobacter, Clostridium, Corynebacterium, E. coli, Erysipelothrix, Haemophilus, Klebsiella, Listeria, Pasteurella, Salmonella, Staphylococcus and Streptococcus spp.
Contra indications
Hypersensitivity to penicillins, procaine and/or aminoglycosides.
Administration to animals with a seriously impaired renal function.
Concurrent administration of tetracyclines, chloramphenicol, macrolides and lincosamides.

Administration of therapeutic dosages of procaine penicillin G can result in abortion in sows.
Ototoxity, neurotoxity or nephrotoxicity.
Hypersensitivity reactions.
