Which analgesic is recommended as safe in the late stages of pregnancy?

• A. Ibuprofen.
• B. Acetaminophen.
• C. Aspirin.
• D. Naproxen.

Answer: (B)

Acetaminophen is preferred in the late stages of pregnancy because it relieves pain and fever without affecting fetal circulation or platelet function, and it has no known teratogenic effects at standard doses. In contrast, NSAIDs like ibuprofen or naproxen can interfere with fetal kidney function and can cause premature closure of the ductus arteriosus, while aspirin carries risks of bleeding and placental problems. Use the lowest effective dose for the shortest time, and avoid exceeding the usual daily limit (about 4 grams per day for adults) or combining with other acetaminophen-containing products to prevent liver injury.
