Bleomycin is an antibiotic with cytotoxic properties, commonly used in combination regimens for the treatment of Hodgkin lymphoma. The inconsistency in dosage nomenclature of bleomycin seems to be universal in many countries, which increases the risk of medication error. However, as far as we know no cases have reported. Here we present a case report of a medication error caused by bleomycin overdose. A 25-year-old patient with Stage II Hodgkin Lymphoma received a 150 USP bleomycin, which dosage was ten times higher than usually used, as part of the doxorubicin, bleomycin, vindesine, dacarbazine protocol (ABVD) at the third cycles of chemotherapy. After the medication error was found, the patient was immediately treated with intravenous rehydration and furosemide to promote clearance of drugs. To prevent lung injury, the methylprednisone and acetylcysteine was given. The patient developed a slight nausea and a mild rash, which gradually improved after the treatment. After the evaluation with PET-CT, the patient received four cycles of AVD chemotherapy. During the treatment and one-year follow-up period, no other obvious abnormalities were observed. The toxicities, clinical managements and selection of further chemotherapy after bleomycin overdose deserved serious attention in this case. More importantly, the management measures after this error can be used for reference in other hospitals.
Bleomycin is an antibiotic with cytotoxic properties that is commonly used in combination regimens for the treatment of Hodgkin lymphoma. The inconsistency in the dosage nomenclature of bleomycin appears universally, which increases the risk of medication errors. However, to the best of our knowledge, no such cases have been reported. Herein, we present a rare case report of a medication error caused by a bleomycin overdose. At the third cycle of chemotherapy, a 25‐year‐old patient with stage II Hodgkin lymphoma received a 10 times higher dose of bleomycin (150 USP) than that usually used as part of the doxorubicin, bleomycin, vindesine and dacarbazine protocol (ABVD). After the medication error was discovered, the patient was immediately treated with intravenous rehydration and furosemide to promote drug clearance. Additionally, methylprednisone and acetylcysteine were administered to prevent lung injury. However, the patient developed slight nausea and mild rash, which gradually improved after treatment. After evaluation with positron emission spectrometry‐computed tomography (PET‐CT), the patient received four cycles of AVD chemotherapy. No other obvious abnormalities were observed during the treatment and 1‐year follow‐up period. Hence, the toxicities, clinical management and selection of further chemotherapy after bleomycin overdose in such cases deserved serious attention. More importantly, management measures after this error may be used as a reference in other hospitals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
