Composition: each 100 ml contains 20 g of Erythromycin base.
Indications: treatment of acute and chronic mastitis, respiratory diseases, bronchitis, tracheitis, tonsillitis, shipping fever, endometritis, metritis and other infectious diseases caused by erythromycin sensitive microorganisms that affect cattle, pigs, sheep, dogs and cats.
It is very effective against certain microorganisms mainly coagulase positive Staphylococcus aureus in bovine mastitis and Pasteurella in pleuropneumonia in calves.
In the treatment of mastitis, parenteral use of this fat soluble antibiotic is highly efficacious with optimal diffusion from the systemic circulation towards glandular tissues, achieving high concentration in the infectious focus.
Administration and dosage: by intramuscular (IM) route, distributing the dose at two injection sites.

Cattle: 2 to 4 ml per 100 kg body weight, every 12 to 24 hours, according to the severity of the clinical condition.
Special treatments:
1. Acute and chronic mastitis, caused by Staphylococcus aureus (coagulase positive or negative), Streptococcus (S. agalactiae, S. dysgalactiae and S. uberis). Dose: 5 ml per 100 kg body weight every 24 hours, repeating according to the severity of the clinical condition.
2. Bronchopneumonia and fibrinous pneumonia with pleuropneumonia caused by Pasteurella, Haemophilus and Staphylococcus in calves during artificial breeding and in bovines during intensive fattening. Dose: 10 ml per 100 kg body weight every 24 hours, repeating according to the severity of the clinical condition.
3. Polyarthritis in calves with lameness and suppurated arthritis of large joints caused by Erysipelothrix rhusiopathiae (formerly E. insidiosa). Dose: 10 ml per 100 kg body weight every 12 hours. It can be combined with 20 mg of Dexametasona Burnet every 36 hours.
4. Acute puerperal mastitis/metritis (puerperal sepsis). Dose: 5 ml per 100 kg body weight every 24 hours (at least for three days), followed by 20 mg of Dexametasona Burnet diluted into one bottle of 400 ml of Power Shock and administered by intravenous (IV) route for 2 days.

Swine:
1. Respiratory conditions: 1 to 3 ml per 100 kg body weight every 24 hours.
2. Swine erysipelas or non-suppurative polyarthritis with serious skin lesions: 1 ml per 100 kg body weight every 24 hours.

Sheep:
1. Respiratory infections: 1 ml per 100 kg body weight every 24 hours.
2. Prevention of enterotoxemia in newborn lambs when the causative agent is Clostridium perfringens type B: 0.625 ml per kg body weight immediately after delivery.

Dogs and cats: Dose: 0.50 ml per 10 kg body weight every 8 hours.

Note: these doses and their repetition depend on the severity of the clinical condition and are subject to professional criteria.
Action: erythromycin is a macrolide antibiotic with activity against Gram positive cocci (Staphylococcus, Streptococcus), Gram positive bacilli (Bacillus anthracis, Corynebacterium, Clostridium, Listeria and Erysipelothrix) and some strains of Gram negative bacilli including Haemophilus, Pasteurella, Brucella. Some strains of Actinomyces, Mycoplasma, Chlamydia, Ureaplasma and Rickettsia are also inhibited. This antibiotic is distributed throughout the body including the mammary gland and cerebrospinal fluid thanks to its liposolubility. It does not have teratogenic effects and can be administer during pregnancy.
Administer according to professional criteria.
