Sneezing and runny nose can’t take cefixime because cefixime belongs to antibiotics, and the application of antibiotics has strict indications. Sneezing and runny nose is only a symptom of cold, and most colds are caused by viruses, so you can’t use antibiotics, just use some symptomatic treatment drugs, not blindly apply cefixime. Cold itself is a self-limiting disease, there is no special medicine, so the treatment of cold drugs are allopathic. Therefore, as long as you rest in bed, drink more water, eat lightly, avoid strenuous exercise, and take symptomatic treatment if necessary, most people can be cured in a week or so without special medication. If you have yellow pus nasal discharge, it means combined with bacterial infection, you can apply antibiotics appropriately.
