It is generally advised not to take Advil (which contains ibuprofen) while pregnant, especially after 20 weeks of pregnancy. Taking ibuprofen during this time can increase the risk of serious pregnancy complications including poor fetal kidney function, low amniotic fluid, premature closure of a blood vessel in the baby's heart, and potential birth defects. In the first trimester, ibuprofen has been linked to higher risks of birth defects and low birth weight. The safest pain reliever during pregnancy is usually acetaminophen (Tylenol), and any medication use should be discussed with a healthcare provider. Non-medication pain relief methods may also be considered safer alternatives during pregnancy.
