It is usually not recommended to eat durian after taking cephalexin. This is because durian is a fruit that is relatively rich in vitamins and trace elements, and has a high nutrient content. However, durian contains a component called histamine. Histamine is a substance that degranulates mast cells and releases allergens and allergy mediators. Durian is rich in histamine, so taking durian after a cephalosporin injection, for example, can accelerate the allergic reaction to the drug, such as the appearance of body rashes, pimples, macules, rashes, rashes, drug rashes, and bumps, all because of an allergic effect after the cephalosporin injection, for some sensitive bodies, and the consumption of durian. Therefore, it is usually not recommended to eat durian immediately after injecting or eating cephalosporin.
