Six hours between a cephalosporin and beer is a no-no. Alcohol should not be consumed inside or outside of six hours before or after taking a cephalosporin or entering a cephalosporin. It is recommended that you do not consume alcohol for 7 to 10 days after using cephalosporins. Cephalosporins inhibit the metabolism of ethanol (i.e., alcohol), causing the body to accumulate too much ethanol and a disulfiram-like reaction to occur. When people have a disulfiram reaction, they may experience dizziness, headache, vomiting, abdominal pain, facial flushing, and other symptoms, and in severe cases, they may have difficulty breathing, drop in blood pressure, and heart failure, which can be life-threatening. When a disulfiram-like reaction occurs, seek medical attention immediately. Disulfiram-like reactions usually occur within 7 to 10 days after the body ingests Cephalosporin. Therefore, it is not acceptable to ingest alcohol or consume food containing alcohol (e.g., wine heart candies, etc.) while taking it.
