What this medicine is for

PRIMAXIN is indicated for the treatment of serious infections caused by susceptible strains of micro-organisms in the diseases listed below: 1. Lower respiratory tract infections. 2 Intra-abdominal infections. 3. Gynaecological infections. 4. Bacterial septicaemia. 5. Bone and joint infections. 6. Skin and skin structure infections. 7. Endocarditis. 8. Polymicrobial infections. PRIMAXIN is indicated for polymicrobial infections including those in which S. pneumoniae (pneumonia, septicaemia), Group A beta-haemolytic streptococcus (skin and skin structure), or non-penicillinase-producing S. aureus is one of the causative organisms. However monobacterial infections due to these organisms are usually treated with narrower spectrum antibiotics, such as penicillin G. Efficacy against polymicrobial infection in the immunocompromised host has not yet been established. Although clinical improvement has been observed in patients with cystic fibrosis, chronic pulmonary disease, and lower respiratory tract infections caused by Pseudomonas aeruginosa, bacterial eradication may not necessarily be achieved. As with other beta-lactam antibiotics, strains of Pseudomonas aeruginosa may develop resistance rapidly on treatment with PRIMAXIN. When clinically appropriate during therapy of Pseudomonas aeruginosa infections, periodic susceptibility testing should be done. Infections resistant to other antibiotics, for example, cephalosporins, penicillin, and aminoglycosides, may respond to treatment with PRIMAXIN. PRIMAXIN is not indicated for the treatment of meningitis.
