Self-medication during pregnancy continues to be an issue in developing countries due to poor medical education. The most commonly used drugs are analgesics, mainly acetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of the study was to establish whether there are consequences of accidental use of these two drugs during early embryogenesis. The experimental study was performed on 30 pregnant white mice, divided into three groups: a first group to which APAP was administered, a second group to which KPF was administered, and group 3 as a control group. At delivery, the baby mice were examined, and after their first parturition, they were taken into study and examined according to the established protocol. Macroscopic and microscopic examinations of the liver and kidney were performed; liver and renal changes were recorded. Regarding the fertility, the number of fetuses born to mothers that were administered APAP and KPF corresponded to the normal values recorded in this species. Microscopic changes that were found in the kidney were as follows: APAP group - necrosis of the urinary tube, vascular congestions and vascular disorders; KPF group - ectasia, especially in the medullary cavity. Microscopic hepatic changes showed in the APAP group - vascular congestions, vascular disorders and hemosiderin deposits in the Kupffer cells; in the KPF group were found - discrete vascular disorders consisting in sinusoidal capillary ectasia and vascular congestions, as well as the presence of lymphocyte conglomerates. The aforementioned lesions indicate hepatic and renal distress with variable degrees of severity, but they appear to be reversible (the longer the time from the maximum effect of the drug the lower its toxicity).
