In this case, we try not to choose drugs for treatment. In addition, if there is obvious inflammation in the routine blood test, antibiotics can be used to treat it. It is also safe to choose cephalosporins for antibiotics. Because drugs can not be used randomly during the whole pregnancy, they can not be used randomly after the symptoms of colds. For symptomatic treatment, antitussive and expectorant drugs, as well as heat clearing and detoxifying drugs, and drugs for burning, warming and relieving exterior symptoms, they can not be used randomly, In particular, we do not recommend the use of Chinese patent medicines for heat clearing and detoxification because of their complex ingredients. Most common colds are caused by viruses, and a few can be combined with bacterial infection. Moreover, common colds have a certain self limitation, so it is not necessary to rush to use antibiotics for treatment. Instead, we can choose some safe antibiotics for backup treatment. We can use them after the blood routine examination has confirmed the inflammation.
