You should not drink alcohol if you have a history of ear infections. Ear inflammation usually has local bacterial infection of the ear caused by local redness, congestion, pain, and pus flow in the ear. In severe cases, oral cephalexin tablets, roxithromycin capsules, and topical boric acid alcohol gauze are needed to control the inflammatory infection. If you drink alcohol when your ear is inflamed, it will stimulate the vasodilatation of the local inflammatory parts of the ear, which will then lead to increased inflammation, making it less likely that the inflammation will recover, with the possibility of bacteremia and sepsis. When cephalosporins are taken orally, drinking alcohol is very likely to cause a disulfiram-like reaction, which can lead to serious complications such as anaphylaxis and respiratory and cardiac arrest in the patient’s body. Therefore, it is necessary to avoid drinking alcohol in ear infections and try to eat lightly.
