Prolonged-release antibiotic for udder drying-off
Intramammary instillation use
Case with 24 syringes of 10 ml, bucket with 96 and 200 syringes of 10 ml.
Composition: each 100 ml contains 1 g Erythromycin base, 2 g Amoxicillin trihydrate.
Indications: to be used during the udder drying-off process. It acts against Streptococcus (S. agalactiae, S. dysgalactiae, S. uberis) and Staphylococcus aureus.
Administration and dosage: by intramammary instillation.
Cattle: instil 10 ml per udder quarter.
Each dose is equivalent to 100 mg of erythromycin and 200 mg of amoxicillin per udder quarter. Cows should be completely milked and the udder and teats should be washed with warm water and a disinfectant. Dry thoroughly and apply a topical antiseptic, such as 70% isopropyl alcohol, using a moistened cotton. Then apply the medication. People who treat the cows should thoroughly wash their hands. Introduce the dose into the mammary duct and then, covering the teat with one hand, massage gently the mammary gland upwards to achieve a uniform distribution. Upon completion, it is recommended to seal the teats.
Administer according to professional criteria.
Contraindications: the product is contraindicated in animals sensitive to any of the active principles. It is not convenient to simultaneously administer erythromycin and lincosamides because both of them bind to the 50S ribosomal subunit and can compete with each other. Erythromycin can inhibit the metabolism of methylprednisolone. In patients treated with warfarin, administration of erythromycin may increase prothrombin time. Do not administer with penicillins.
