It is recommended not to take medication within one week after drinking alcohol. Especially when taking cephalosporins, alcohol should not be consumed for a week before and after taking the drugs, because most of the drugs are metabolized by the liver and excreted by the kidneys, and alcohol can affect the activity of liver drug enzymes, so it is best not to drink alcohol during taking the drugs, otherwise it will affect the metabolism and excretion of the drugs. In addition, some drugs are highly irritating to the gastrointestinal tract, and alcohol can aggravate its gastrointestinal irritation, thus aggravating the gastrointestinal reaction and even causing gastrointestinal bleeding. In addition, the body’s immunity is low when you are sick, so alcohol and tobacco are not conducive to recovery from illness, so alcohol should be prohibited during illness.
