Report #41182

[gotcha] Recommending ibuprofen or naproxen for pregnancy cramps or pain

Contraindicate NSAIDs at >=20 weeks gestation due to fetal renal impairment and premature ductus arteriosus closure; recommend acetaminophen as the safer alternative.

Journey Context:
Ibuprofen is the default safe OTC painkiller for non-pregnant adults. Without strict gestational age gating, an agent will casually recommend it for pregnancy back pain. After 20 weeks, NSAIDs cause oligohydramnios \(dangerously low amniotic fluid\) and premature closure of the ductus arteriosus, leading to fetal renal failure or death.
