Migraine treatment in pregnancy: Planning With Your Prescriber

Migraine may improve during pregnancy, but not everyone has fewer attacks. A treatment plan should cover what to do during an attack, whether prevention is needed and which changes require urgent assessment. Your previous migraine pattern is useful information, not a reason to dismiss every new headache.

Review acute and preventive treatment separately

Bring a list of medicines used when an attack starts and anything taken regularly to prevent attacks. Include combination tablets and treatments bought without a prescription. Explain how often attacks occur, how long they last and whether vomiting makes tablets difficult to take.

Paracetamol is often the first option for pain. A prescriber may consider sumatriptan or a medicine for nausea when appropriate. Do not add ibuprofen or another NSAID yourself, particularly from 20 weeks onward. The pain relief guide explains the changing precautions later in pregnancy.

Check topiramate promptly

Topiramate must not be used to prevent migraine during pregnancy. UK safety advice says that if you think you are pregnant while taking it for migraine prevention, stop it straight away and contact your GP. The medicine has specific pregnancy prevention requirements because of risks to fetal development.

The instruction differs when topiramate treats epilepsy: do not stop it yourself, because seizures can return or worsen. Arrange urgent advice from your GP or epilepsy team. Tell them if it has been prescribed for more than one reason so the next step is clear.

Other preventive treatments also need review. Ask your prescriber which option best balances migraine control and pregnancy safety, and whether monitoring will change. A medicine that worked well before pregnancy may need a different plan now.

Keep a short attack record

Note headache days, medicines taken, sleep, meals and possible triggers. Regular rest, hydration and avoiding a known trigger may help, but these measures do not work for everyone. Frequent disabling attacks warrant medical support rather than expecting you to manage through lifestyle alone.

The medicine review guide can help you keep recommendations from the maternity team and migraine prescriber in one place. Ask whom to contact if the agreed treatment stops working.

Treat warning symptoms as a separate issue

Contact your GP or maternity team promptly for a migraine attack during pregnancy, particularly if it is new or different from your usual pattern.

A severe headache, blurred vision or flashing lights, pain under the ribs, vomiting or sudden swelling needs immediate maternity advice. These can be signs of preeclampsia, which usually develops after 20 weeks. Do not wait for all the symptoms to appear together.

A sudden extremely painful headache, new weakness, difficulty speaking or a seizure is an emergency. Seek emergency care rather than assuming it is your usual aura. The clinician can assess the cause before deciding on migraine treatment.
