Since there are particularly many types of cold medicines, the effects on pregnancy can vary greatly from one cold medicine to another. If a woman is only taking Sanjiu Cold & Flu, or Shuanghuanglian Oral Liquid to treat a cold, and she finds out that she is pregnant, there are no particular adverse effects, and these cold medicines are cold medicines that can be taken by pregnant women, even if they develop a cold during pregnancy. However, if a woman is taking Levofloxacin, or Gentamicin, or even the antiviral Ribavirin, it will have an adverse effect on the fetus, and may affect the growth and development of the fetus, leading to embryonic stasis, preterm miscarriage, or even fetal deformities, and so this will require consideration as to whether or not the pregnancy can continue.
