It is recommended not to drink tea when taking cephalosporin, because cephalosporin is a broad-spectrum antibiotic, mainly for broad-spectrum gram-positive and gram-negative bacteria, have a good killing effect, and can be used in clinical treatment of bronchitis, pneumonia, lung abscess, etc. And tea contains a large number of catecholamines, tea polyphenols, and theophylline, if you drink tea at the same time when taking cephalosporin, it may affect the metabolism of cephalosporin drugs in the body, especially it may agglomerate and precipitate with cephalosporin, reducing the efficacy of the drug. In addition, tea contains a large amount of catecholamines, which can make the body relatively excited and vasoconstricted, especially for patients with allergies, which may induce different degrees of allergic reactions to cephalosporin. Therefore, in the process of being used to treat anti-bacterial diseases, do not drink tea while taking cephalosporin, but can take it with warm boiled water.
