RESUMO
OBJECTIVE:To analyze the characteristics and regularity of cross allergic reaction between carbopenems and penicillin.METHODS:2 cases about cross allergic reaction between ertapenem and penicillin were reported,716 cases of cross allergic reaction between carbopenems and penicillin in 9 literatures were collected from databases from Jan.1986 to Jan.2010 and analyzed statistically.RESULTS:The incidence of allergic reactions caused by carbopenems in patients with allergic history were higher than that in patients without allergic history.Allergic reaction mostly occurred within 15 min～49 d.Sound therapeutic efficacy can be achieved because of immediate withdrawal of drug and anti-allergy treatment,patients were with good prognosis.CONCLUSION:Great importance should be attached to monitoring of cross allergic reaction between carbopenems and penicillin and rational use of drugs.
