Final answer:
Acetaminophen (paracetamol) is the recommended analgesic for back pain during pregnancy.
Step-by-step explanation:
During pregnancy, when experiencing back pain, it is important to choose analgesics that are safe for both the mother and the baby. The recommended analgesic for back pain during pregnancy is acetaminophen (paracetamol). It is considered safe to use and does not pose significant risks to the mother or baby when taken at recommended doses. However, other analgesics such as ibuprofen, aspirin, and naproxen are not recommended during pregnancy as they can potentially harm the baby.
