It is generally not recommended to take proprietary Chinese medicines after drinking beer to avoid reactions causing discomfort or affecting the efficacy of the medicine.

After drinking beer and then taking pCms, the alcohol in the beer may interact with one of the ingredients in the pCms and adversely affect the body, such as increasing the probability of alcohol and drug allergy, abdominal pain, bloating, diarrhea, or even poisoning.

Therefore, it is not recommended to take pCms after drinking beer. If the patient must use the medicine, must first consult a professional doctor, do not blindly take by yourself, in order to avoid discomfort symptoms.
