The need for pharmacotherapy during pregnancy is increasingly encountered. Pregnancy does not protect a woman from various viruses and bacteria, but pregnancy itself can significantly affect the course of the disease. There are diseases that are specific to the period of pregnancy, but a pregnant woman can also contract common seasonal infections. At present, the phenomenon of postponing motherhood to an older age, with women having their first offspring after the age of 35, contributes to the above-mentioned facts. This brings with it many risks to pregnancy that may be associated with drug therapy. The aim of this article was to provide comprehensive information on the use of medications in pregnancy, including the suggestion of pharmacological and non-pharmacological therapies for common diseases that occur commonly in the population.
