Cefixime granules are an oral cephalosporin antibiotic, and the symptoms of allergy are actually similar to those of other cephalosporins. The most likely symptom of allergy is a mild itching of the skin and some rashes, which are actually called allergic urticaria. When hives occur, the itching may vary depending on the amount of the rash, which is a relatively mild condition. If it is more severe, it may also be accompanied by breathing difficulties, and the occurrence of breathing difficulties proves that the corresponding allergy is more serious. If detected early, the symptoms can be controlled by taking appropriate measures such as stopping cefixime or using some anti-allergy medication. If there is a particularly obvious allergic reaction, then the symptoms of generalized rash, chest tightness and itching may come more quickly. Even if there is anaphylactic shock, the patient’s chest tightness will be more obvious at this time, and it is likely to be accompanied by dizziness and sweating, which need to be dealt with promptly.
