Can I eat dishes containing cooking wine after taking cephalosporin?
Under normal circumstances, dishes containing cooking wine should not be consumed during the course of taking cephalosporin antibiotics or within one week after stopping the medication. Individuals who have discontinued the drug for more than a week and experience no discomfort may consume such dishes in small amounts. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed explanations are as follows:

If you are currently taking cephalosporin antibiotics or have stopped taking them less than a week ago, you should avoid eating any dishes containing cooking wine—even if only a small amount is used. Cooking wine contains alcohol, which can interact with cephalosporins and potentially cause adverse reactions such as facial flushing, headache, nausea, and dizziness. In severe cases, it may affect breathing and blood pressure, posing a health risk. This risk remains present for up to one week after discontinuation of the drug.
If more than a week has passed since stopping cephalosporin use and you are experiencing no discomfort, it is likely that alcohol has been fully metabolized, and you may cautiously consume small amounts of food prepared with cooking wine. At this point, the risk of interaction between the medication and alcohol is significantly reduced. However, intake should still be limited, and excessive consumption of alcohol-containing foods at one time should be avoided to prevent unexpected complications.
During treatment with cephalosporins, all foods and beverages containing alcohol must be strictly avoided. Even after stopping the medication, sufficient waiting time is necessary. If symptoms suggestive of an adverse reaction occur, seek immediate medical attention without delay.
