Beta-lactam allergy is the most prevalent drug allergy. Drug eruption is the most common symptom whereas life-threatening anaphylaxis is rather rare. A recently published study (Journal of Allergy and Clinical Immunology, January 2011, Vol. 127, p. 218-222) described the safety of a 2-day oral beta-lactam challenge in penicillin-allergic patients, disregarding their penicillin skin test results. In the proposed study the investigators will similarly challenge beta-lactam allergic patients, both children and adults for an extended (5 days) period of time. The study will include patients with a history of a skin rash following beta-lactam administration as well as patients who cannot provide any data on their presumed allergic reaction, disregarding their penicillin skin test results.

Condition Intervention
Beta-lactam Allergy Drug: Beta-lactam oral challenge

Primary Outcome Measures:
  • The safety of a 5-day oral challenge in patients with suspected beta-lactam allergy [ Time Frame: 5 days ]
    In case of the development of any adverse reactions throughout the 5-day challenge patients will notify the investigators over the phone. If assessed necessary by the investigators, patients will return to the Allergy Clinic for repeated evaluation. After completion of the 5-day challenge all patients will be contacted by the investigators and will be inquired about any adverse reactions throughout the challenge. The number of participants with adverse reactions to the challenge will be reported.

Estimated Enrollment: 200
Study Start Date: March 2012
Study Completion Date: June 2015
Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Beta-lactam oral challenge
    Oral daily dose, according to patient's weight, of amoxicillin or other suspected beta-lactam will be administered for 5 consecutive days

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • History of skin rash following the administration of beta-lactam antibiotic
  • Patients with a diagnosis of penicillin allergy who have no data on the nature of the symptoms that have eventually resulted in establishing this diagnosis

Exclusion Criteria:
