After drinking beer, it is recommended to take cefixime after 7 days, mainly to avoid the serious consequences that may be triggered by disulfiram-like reactions.
After drinking, alcohol is absorbed through the oral mucosa, stomach and small intestine, and can be fully absorbed in about 2 hours. 90% is metabolized and eliminated through the liver, while the rest is mainly excreted through respiration and urine.
Cephalosporin antibiotics (such as cefixime) will inhibit the enzyme acetaldehyde dehydrogenase, affecting the decomposition process of alcohol, i.e., ethanol, which will lead to the accumulation of acetaldehyde in the body, triggering acetaldehyde intoxication and causing symptoms such as panic attacks, tightness in the chest, and difficulty in breathing, a process known as the bisulfite-like reaction.
Within 24 hours after drinking alcohol, alcohol in the body can be completely metabolized by the body, some liver insufficiency may be metabolized for a longer period of time, 7 days before oral cefixime is relatively safer, emergencies can be taken other antibiotics such as penicillin, for treatment.
The use of antibiotics is recommended under the guidance of a specialized doctor.
