For the use of drugs during pregnancy, the principle is: the available drugs can be used as far as possible, the general cold drugs, especially Chinese medicine preparations, is relatively safe, such as Banlangen punch, etc.. In addition, penicillin, erythromycin, cephalosporins, etc., have been tested on animals and applied to humans, and have not been proven to be harmful to the fetus, so they can be applied. If acetylsalicylic acid drugs are taken before 9 weeks of pregnancy, they can cause fetal malformation and should be avoided. If a cold is accompanied by high fever, Tylenol can be used to reduce the fever. At the same time, cold compresses of wet towels and baths of about 99% alcohol can also be used as physical cooling treatment. If there is an increase in white blood cells and an increased percentage of neutral classification, antibiotics such as cephalosporin or azithromycin should be considered as appropriate. Most of the anti-cold medicines are compound preparations, and experts suggest that mothers-to-be should not use anti-cold medicines; antiviral drugs generally have adverse effects on the fetus and should not be used by mothers-to-be; anti-inflammatory painkillers are contraindicated for mothers-to-be; antipyretics and antibiotics should be taken under the guidance of a doctor; expectorants are mainly phlegm, and cough medicines are generally not recommended because of their dubious efficacy.
