Taking naproxen during pregnancy is generally not recommended, especially after 20 weeks of gestation, due to potential risks to the baby such as problems with circulation, reduced amniotic fluid, and early closure of a vital blood vessel in the lungs (ductus arteriosus). Naproxen may also increase the risk of miscarriage when used in early pregnancy. It should only be taken if prescribed by a doctor who determines that the benefits outweigh the risks. Safer alternatives like paracetamol are usually preferred during pregnancy.
Key risks of naproxen use in pregnancy:
- Use after 20 weeks can cause reduced amniotic fluid and affect baby's lung/kidney development.
- May cause premature closure of the ductus arteriosus, a serious fetal heart complication.
- Possible increased miscarriage risk in early pregnancy.
- Should be avoided especially in the third trimester.
- Use should be limited to the lowest effective dose and shortest duration if necessary.
In summary, naproxen is not safe for routine use during pregnancy and alternatives like paracetamol are preferred. If naproxen is considered necessary, close medical supervision is critical to minimize risks to the mother and baby.
