Study Notes
Sensitivity of Embryonic Development
- The most sensitive time for embryonic damage occurs during the first trimester, particularly during organogenesis when major structures are being formed.
Thalidomide Disaster
- Severe limb and organ deformities in babies were primarily caused by thalidomide, a drug that was marketed as a safe sedative but was later found to disrupt prenatal development.
Animal Testing Assumptions
- The assumption that adverse effects observed in animals will not occur in humans can be misleading; differences in metabolism and development between species can lead to unforeseen risks for humans.
Understanding Drug Impacts
- Women should be aware that many drugs can cross the placenta and potentially harm the developing fetus, emphasizing the importance of caution when considering medication during pregnancy.
Primary Consideration for Pregnant Women
- When a woman becomes ill during pregnancy or needs medication, the primary consideration should be the safety of the fetus, balancing maternal health needs with potential risks to fetal development.
