Paracetamol Use in Pregnancy
Information for patients
Why this matters
Many people use paracetamol in pregnancy to treat pain or fever. Recently, studies have looked at whether taking paracetamol in pregnancy might affect a child's brain development.
What the research shows
Some studies suggest that frequent or long-term use of paracetamol in pregnancy may be linked to a slightly higher chance of conditions like autism or ADHD in children.
One study even measured paracetamol in umbilical cord blood and found higher levels were linked with a higher risk.
However, other strong studies (including those comparing siblings) did not find a clear link.
This means: research shows a possible association, but it does not
prove cause and effect.
Why paracetamol is still recommended
Fever in pregnancy can be harmful to the baby if not treated. Paracetamol is considered the safest option for pain and fever relief in pregnancy.
Other medicines (such as ibuprofen) can have known risks in pregnancy.
Expert bodies (such as the Royal College of Obstetricians and Gynaecologists and NICE) still recommend paracetamol as the first
choice.
Safe use in pregnancy
• Use paracetamol only if needed.
• Take the lowest effective dose for the shortest possible time.
• Always follow the instructions on the packaging or those given by your healthcare
professional.
• If you find yourself taking paracetamol regularly (for example, every day), please speak
with your midwife, GP, or pharmacist.
Other ways to manage discomfort
• For headaches: hydration, rest, cool cloths.
• For muscle aches: gentle stretching, warm baths, heat/cold packs.
• For fever: fluids, light clothing, and medical review if the fever is high or persistent.
Bottom line
Occasional, short-term use of paracetamol in pregnancy is still considered safe and appropriate. Use it wisely, and talk to your healthcare team if you have concerns or need to use it often.
Never avoid treating a fever in pregnancy — controlling fever is important
for your baby's health.
