Not active against methicillin-resistant staphylococci or enterococci.

Pharmacokinetics

Absorption: Well absorbed after IM administration; IV administration results in complete bioavailability.Distribution: Widely distributed. Crosses the placenta; enters breast milk in low concentrations. Some CSF penetration.Protein Binding: 20%.Metabolism and Excretion: 85% excreted unchanged in urine.Half-life: Adults–2 hr (↑ in renal impairment); Children 2 mo–6 yr—1.7–1.9 hr.

Nursing implications

Nursing assessment

  • Assess patient for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and throughout therapy.
  • Before initiating therapy, obtain a history to determine previous use of and reactions to penicillins or cephalosporins. Persons with a negative history of penicillin sensitivity may still have an allergic response.
  • Obtain specimens for culture and sensitivity before initiating therapy. First dose may be given before receiving results.
  • Observe patient for signs and symptoms of anaphylaxis (rash, pruritus, laryngeal edema, wheezing). Discontinue the drug and notify health care professional immediately if these symptoms occur. Keep epinephrine, an antihistamine, and resuscitation equipment close by in the event of an anaphylactic reaction.
  • Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of pseudomembranous colitis. May begin up to several weeks following cessation of therapy.
  • Lab Test Considerations: May cause positive results for Coombs' test in patients receiving high doses or in neonates whose mothers were given cephalosporins before delivery.
    • May cause ↑ serum AST, ALT, bilirubin, BUN, and creatinine.
    • May rarely cause leukopenia, neutropenia, thrombocytopenia, and eosinophilia.

Evaluation/Desired Outcomes

  • Resolution of the signs and symptoms of infection. Length of time for complete resolution depends on the organism and site of infection.
