Paracetamol in Pregnancy: NHS First-Choice Painkiller

Paracetamol in pregnancy: how to think about it

NHS medicine guidance states that paracetamol is the first choice of painkiller if you are pregnant, and that it has been taken by large numbers of pregnant people without evidence of harm to the baby. The framing in that guidance is nonetheless to take the lowest effective dose for the shortest time, and to speak to a doctor if you need to take it for longer than a couple of days. MotherToBaby publishes a fact sheet on acetaminophen, the same medicine under its US name, covering pregnancy exposure in more detail. Paracetamol has been the subject of public debate and media coverage, and professional bodies have continued to recommend it as the preferred option in pregnancy while advising sensible use rather than routine long-term dosing. The practical risks people meet in daily life are accidental double dosing from combination products and using it to mask a symptom that needs assessment.

Paracetamol: safer choices

• Taking paracetamol at the lowest dose that works, for the shortest time needed, which is how NHS guidance frames it rather than as an open-ended option.
• Following the label dose, usually one or two 500 mg tablets every four hours, with a maximum of eight 500 mg tablets in 24 hours for adults.
• Checking with your midwife, pharmacist or GP if you find you need it regularly or for more than a day or two, so the underlying cause gets looked at.
• Reading the full ingredient list on any cold, flu or pain product, since paracetamol appears inside many combination products under different brand names.

Paracetamol: what to avoid or double-check

• Do not exceed the maximum daily dose. Taking paracetamol from two products at once is the common way people accidentally double up.
• Avoid combination cold and flu products without checking every active ingredient. Many contain paracetamol plus a decongestant or caffeine that may need separate consideration.
• Do not switch to ibuprofen or other NSAIDs on your own as an alternative, particularly from 20 weeks, where separate warnings apply. Ask first.
• Do not use paracetamol to manage ongoing or severe pain, recurring headaches, or fever without speaking to a clinician about the cause.
