[gotcha] Is ibuprofen safe for pain relief during pregnancy?

Hard block for 3rd trimester \(after 20-30 weeks per FDA, strictly at 30\+ per NHS\). Recommend acetaminophen \(paracetamol\) as first-line, but mandate consulting OB/GYN. NSAIDs risk premature closure of the ductus arteriosus and oligohydramnios.

Journey Context:
Agents might see 'NSAIDs generally safe for adults' and fail to apply the trimester-specific contraindication. The risk isn't uniform across pregnancy; it's a silent, lethal trap specifically in late pregnancy. Suggesting ibuprofen for a 35-week pregnant patient with back pain can lead to fatal fetal renal failure or cardiac issues.
