Adverse reactions to prolonged treatment with high doses of carbenicillin and ureidopenicillins

Research output: Contribution to journalArticlepeer-review


Charts were reviewed for 63 patients whose chronic pseudomonas osteomyelitis was treated with high doses of extended-spectrum penicillins for prolonged periods. The incidence of untoward drug reactions was significantly higher than expected. Carbemcillin evoked adverse reactions in 22.8% of patients. However, most of these reactions were mild, and a change of drug was required in only 5.7% of cases. No adverse drug reactions were observe WIth cuumulative doses of <750 g. In contrast to carbenicillin, the ureidopenicillins were associated with adverse reactions in 67.7% of patients; most reactions were moderate to severe in intensity; a cumulative dose of >250 g produced adverse reactions; and discontinuation or change of therapy was required in 51.6% of cases. The main adverse reactions to both carbemcilll? and the ureidopemcillins included rash, drug fever, leukopenia, eosinophilia, thrombocytopema, and hepatic damage.
