If bacterial infection occurs during pregnancy, it can be treated with reasonable oral cephalosporin antibiotics under doctor’s guidance. There are many types of cephalosporin antibiotics, which are mainly effective against bacterial infections, and can treat respiratory tract infections and skin and soft tissue infections caused by sensitive bacteria. These drugs have been clinically proven to have less impact on the fetus and the mother, and generally do not affect the normal development of the fetus, so the diagnosis of bacterial infections during pregnancy can be reasonably used in accordance with medical advice when drug allergies are ruled out. Cephalosporin antibiotics also have certain adverse reactions, such as gastrointestinal symptoms, dysbiosis, pseudomembranous enteritis, etc., so even if pregnant women can be used, but also need to be careful not to use long-term overdose, if there is any discomfort during the period of use and timely follow-up.
