It is not recommended to drink alcohol after taking penicillin, firstly, drinking alcohol while taking the medicine will increase the burden on the liver and affect the metabolism of the drug, and secondly, drinking alcohol during penicillin treatment of infection is not conducive to the recovery of the condition. Although it is currently believed that penicillin will not have a disulfiram-like reaction with alcohol and be fatal, but through the intravenous infusion of penicillin into the body needs to be metabolized by the liver, alcohol also needs to be metabolized by the liver, drinking alcohol will increase the burden on the liver, affecting the metabolism of the drug, and potentially damaging the liver. During penicillin administration, a certain degree of infection exists in the body and anti-infective treatment is needed. Drinking alcohol during anti-infective treatment will affect immunity, affecting the recovery of the disease, and may also lead to other adverse reactions, such as vomiting, gastrointestinal discomfort, etc. Therefore, during the period of penicillin, in order to their own health, to promote the recovery of the disease, do not recommend drinking alcohol.
