Drinking alcohol with a cold or fever can aggravate the condition and is not conducive to recovery, and may lead to pneumonia and bronchitis. Because a cold itself is caused by a viral or bacterial infection, it means that the body is overheated and alcohol is a very hot food. If you drink alcohol at this time, it can aggravate the symptoms of the cold and worsen the bacterial or viral infection. If you have a sore throat or bacterial infection when you have a cold, you need to take antibiotics for treatment, and you should not drink alcohol while taking antibiotics. All things containing alcohol should not be consumed, so if you drink alcohol when you have a cold or fever, it will affect the use of the medication. Cephalosporins and alcohol together can easily produce a dangerous disulfiram-like reaction.
