You can eat seafood after taking cephalosporin, but it should be noted that cephalosporin is a western drug and cephalosporin is also an antibiotic drug. Therefore, if you want to eat seafood after taking cephalosporin, you should pay special attention to not eating seafood that is cooked too spicy and irritating. If the seafood is too spicy, it will affect the efficacy of cephalosporin, so it is better to choose to eat lightly cooked seafood. If adverse reactions occur after taking cephalosporin and eating seafood, it is recommended that you should go to the hospital in time for consultation. The diagnosis should be confirmed under the guidance of the doctor, so that the relevant treatment can be carried out. It is recommended to eat seafood after cephalosporin preferably not to choose to eat fruit, because seafood is rich in calcium and protein and other nutrients. So if you eat fruit when you eat seafood because of the acidity in the fruit, it will affect the absorption of protein and other nutrients by your own organism. The acid in the fruit combined with the calcium in the seafood will form insoluble substances, which will produce corresponding stimulation to the gastrointestinal tract of the own organism and cause adverse reactions.
