Taking ibuprofen during pregnancy is generally not recommended, especially after 20 weeks and particularly in the third trimester. Ibuprofen can cause serious risks to the baby, including premature closing of the ductus arteriosus (a vital blood vessel in the fetus), low amniotic fluid levels, and potential heart and kidney problems. It may also increase the risk of miscarriage when taken early in pregnancy. Paracetamol (acetaminophen) is considered a safer alternative for pain relief during pregnancy, but any medication should be taken under medical supervision.
Key Risks of Ibuprofen During Pregnancy
- After 20 weeks, ibuprofen may reduce amniotic fluid, cause premature closure of the ductus arteriosus, leading to lung and heart problems in the baby.
- It may increase the risk of miscarriage, especially if taken near conception.
- Potential risks of birth defects and developmental issues have been suggested but are not conclusively proven.
- Use is especially contraindicated from week 28 onwards (third trimester).
Recommendations
- Avoid ibuprofen unless prescribed by a doctor who will monitor the pregnancy closely.
- Consider acetaminophen as the primary pain relief option during pregnancy.
- Always consult a healthcare provider before taking any medication while pregnant.
