Can I drink alcohol after taking cephalosporin for three days?

Generally, you should not drink alcohol three days after taking cephalosporins, as the medication may not have been fully metabolized. Drinking alcohol could trigger a disulfiram-like reaction.

Cephalosporins refer to a class of antibiotic drugs, commonly including cefixime capsules and cefdinir tablets, which have anti-inflammatory effects. After ingestion, it usually takes about seven days for the drug to be mostly eliminated from the body. Therefore, alcohol should be avoided during treatment with cephalosporins and for seven to ten days after discontinuation. Thus, even three days after taking cephalosporins, drinking alcohol is generally not recommended. This is because alcohol can be converted into acetaldehyde in the body, which may interact with cephalosporins and cause a disulfiram-like reaction. This reaction can lead to symptoms such as chest tightness, shortness of breath, nausea, headache, dizziness, facial flushing, and difficulty breathing. In severe cases, it may result in hypotension or shock. The severity of these symptoms is typically proportional to the dose of medication taken and the amount of alcohol consumed.

While taking cephalosporins, patients should also avoid other foods containing alcohol, such as liqueur chocolates and drunken shrimp, to prevent adverse reactions.
