A case study of impaired consciousness caused by alcohol consumption in a pediatric patient taking high-dose cefixime.

ABSTRACT

A variety of drugs have been known to induce disulfiram-like reactions in individuals exposed to ethanol, including certain cephalosporin antibiotics with methylthiotetrazole (MTT) substituents or methylthiodioxotriazine (MTDT) rings. Among cephalosporins, cefixime is known to cause fewer disulfiram-like reactions. This case report, the first involving a pediatric patient, presents the scenario of a 14-year-old female who exhibited drowsiness, loss of consciousness, and cold extremities within an hour after ingesting 9 cefixime capsules. Upon admission, drug intoxication was considered, prompting immediate gastric lavage and toxicology tests, which revealed the presence of both cefixime and alcohol. Subsequent monitoring of vital signs, rehydration, and symptomatic treatments aimed at facilitating toxic excretion were administered during hospitalization. Following initial assessment by a clinical pharmacist, drug intoxication was deemed improbable, though an atypical disulfiram-like reaction or alcohol intoxication could not be ruled out. Further evaluation, coupled with the child's cefixime overdose, suggested an atypical disulfiram-like reaction. This case underscores the potential for disulfiram reactions even with cephalosporins lacking MTT substituents or MTDT rings. Notably, it is the first report of an atypical disulfiram-like reaction triggered by alcohol consumption following cefixime overdose, emphasizing the importance of caution in cefixime usage and avoidance of alcohol or alcohol-containing substances.
