Antibiotic Recommendations with Penicillin or Cephalosporin Allergy

Determine risk stratification based on Penicillin ADR (HISTORICAL) Clinical Pathway

Allergy

Treatment Recommendations

Notes

Penicillin: Low risk OR High risk for IgE-mediated reaction
(including prior anaphylaxis)
Cefpodoxime
5 mg/kg/dose PO BID (max 200 mg/dose)
  • Consider observed oral dose for patients with low risk of IgE-mediated reaction

  • Risk of penicillin/cephalosporin cross-reactivity is low

  • Most cephalosporins can be given without testing or additional precautions

  • Some cephalosporins have limited availability or variable insurance coverage

Cefuroxime
250 mg PO BID for children able to swallow pills
Cefixime 4 mg/kg/dose PO BID (max 200 mg/dose)
PLUS
Clindamycin 10 mg/kg/dose PO TID (max dose 600 mg/dose)
Penicillin: High risk for
severe delayed reaction
(severe cutaneous reactions (e.g., SJS, DRESS)
Levofloxacin
10 mg/kg/dose PO BID (6 mo - 5 years) OR qday (> 5 years) 
(max 500 mg/day)
  • Avoid cephalosporins unless testing/challenge is completed and determined to be safe

Cephalosporin: Low risk for
IgE-mediated reaction

Amoxicillin 45 mg/kg/dose PO BID (max 2000 mg/dose)
  • Penicillin can be given without testing or additional precautions 
Amoxicillin-clavulanate 45 mg/kg/dose (amoxicillin component) PO BID (max 2000 mg/dose)
Cephalosporin: High risk for
IgE-mediated or severe delayed reaction (e.g., SJS, DRESS)
Levofloxacin
10 mg/kg/dose PO BID (6 mo - 5 years) OR qday (> 5 years)
(max 500 mg/day)
  • Avoid penicillins until skin testing and medication challenge is completed and determined to be safe

Recommend referral for beta lactam allergy testing and potential de-labeling.
At Children's Mercy, Infectious Diseases Clinic provides penicillin testing and Allergy Immunology Clinic provides testing for ALL beta lactams.

These pathways do not establish a standard of care to be followed in every case. It is recognized that each case is different, and those individuals involved in providing health care are expected to use their judgment in determining what is in the best interests of the patient based on the circumstances existing at the time. It is impossible to anticipate all possible situations that may exist and to prepare a pathway for each. Accordingly, these pathways should guide care with the understanding that departures from them may be required at times.
