Category D drugs have evidence of risk to the human fetus based on studies, but they may be used in life-threatening situations where safer drugs cannot be used. Even in low doses, exposure during pregnancy can still harm the baby, potentially causing birth defects, developmental delays, or pregnancy complications. If a midwife believes it’s safe “because it’s only a low dose,” that’s risky because the damage can occur regardless of amount, especially during critical stages of fetal development. I would professionally intervene by explaining the classification system, showing the risks with medical references, and suggesting safer alternative medications. This ensures the patient’s safety and follows ethical standards in maternal care.
