Introduction: The main aim of this review is to bring forth the information about adverse drug events that take place because of the consumption of various sorts of medications during pregnancy and also to create awareness regarding birth defects. Not only the recognition of the unfavorable results of the drugs is difficult, but avoiding some of the medications, even during pregnancy, becomes out of the question. The non-inclusion of pregnant females in clinical trials is another factor adding to this problem. It was only after the thalidomide incidence when pharmacovigilance in pregnancy drew focus. Till today, many drugs have been reported to have severe outcomes on the developing fetus which have also had a great impact on their lives.

Methods: Several literary works from various platforms like Google Scholar, PubMed, The Lancet, American Journal of Perinatology, and many others concerning the adverse drug reactions during pregnancy and related fetal disadvantages were thoroughly reviewed.

Results: This review can cater us with a brief idea of the unpleasant results of antidepressants, antibacterials, antihypertensives, NSAIDs, and antithyroid drugs taken during the phase of pregnant nine months. Vaccines, on the other hand, are comparatively safe to use on preggers and are reported with no adverse results. Corona virus was also reported to cause serious illness in pregnant females. However, there were no reports of its vertical transmission. Drug exposure during pregnancy is not completely risk-free and can result in cardiac and CNS malformations, neural tube defects, and many other serious disorders.

Discussion: Numerous unpleasant reactions of the drugs on pregnant females and newborns have been unveiled. Nevertheless, many more such studies are obligatory for bringing forth new knowledge of the unfavorable outcomes of various drugs.
