Ads
  • Therapeutic: PIPRACIL is indicated for the treatment of serious infections caused by susceptible strains of the designated microorganisms in the conditions listed below:

    Intra-Abdominal Infections including hepatobiliary and surgical infections caused by E. coli, Pseudomonas aeruginosa, enterococci, Clostridium spp., anaerobic cocci, or Bacteroides spp., including B. fragilis.

    Urinary Tract Infections caused by E. coli, Klebsiella spp., P. aeruginosa, Proteus spp., including P. mirabilis, or enterococci.

    Gynecologic Infections including endometritis, pelvic inflammatory disease, pelvic cellulitis caused by Bacteroides spp., including B. fragilis, anaerobic cocci, Neisseria gonorrhoeae, or enterococci (E. faecalis).

    Septicemia including bacteremia caused by E. coli, Klebsiella spp., Enterobacter spp., Serratia spp., P. mirabilis, S. pneumoniae, enterococci, P. aeruginosa, Bacteroides spp., or anaerobic cocci.

    Lower RespiratoryTract Infections caused by E. coli, Klebsiella spp., Enterobacter spp., P. aeruginosa, Serratia spp., H. influenzae, Bacteroides spp., or anaerobic cocci. Although improvement has been noted in patients with cystic fibrosis, lasting bacterial eradication may not necessarily be achieved.

    Skin and Skin Structure Infections caused by E. coli, Klebsiella spp., Serratia spp., Acinetobacter spp., Enterobacter spp., P. aeruginosa, Morganella morganii, Providencia rettgeri, Proteus vulgaris, P. mirabilis, Bacteroides spp., including B. fragilis, anaerobic cocci, or enterococci.

    Bone and Joint Infections caused by P. aeruginosa, enterococci, Bacteroides spp., or anaerobic cocci.

    Uncomplicated Gonococcal Urethritis caused by N. gonorrhoeae.

    PIPRACIL has also been shown to be clinically effective for the treatment of infections at various sites caused by Streptococcus species including S. pyogenes and S. pneumoniae; however, infections caused by these organisms are ordinarily treated with more narrow spectrum penicillins. Because of its broad spectrum of bactericidal activity against gram-positive and gram-negative aerobic and anaerobic bacteria, PIPRACIL is particularly useful for the treatment of mixed infections and presumptive therapy prior to the identification of the causative organisms.

    Also, PIPRACIL may be administered as single drug therapy in some situations where normally two antibiotics might be employed.

    Piperacillin has been successfully used with aminoglycosides, especially in patients with impaired host defenses. Both drugs should be used in full therapeutic doses.

    Appropriate cultures should be made for susceptibility testing before initiating therapy and therapy adjusted, if appropriate, once the results are known.

    Prophylaxis: PIPRACIL is indicated for prophylactic use in surgery including intra-abdominal (gastrointestinal and biliary) procedures, vaginal hysterectomy, abdominal hysterectomy, and cesarean section. Effective prophylactic use depends on the time of administration; PIPRACIL should be given one-half to one hour before the operation so that effective levels can be achieved in the site prior to the procedure.

    The prophylactic use of piperacillin should be stopped within 24 hours, since continuing administration of any antibiotic increases the possibility of adverse reactions, but in the majority of surgical procedures, does not reduce the incidence of subsequent infections. If there are signs of infection, specimens for culture and susceptibility testing should be obtained for identification of the causative microorganism so that appropriate therapy can be instituted.

    To reduce the development of drug-resistant bacteria and maintain the effectiveness of PIPRACIL and other antibacterial drugs, PIPRACILshould only be used to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
