Headaches in pregnancy: When a Headache Needs Prompt Review

Headaches can occur in pregnancy, particularly in the early weeks. A mild familiar headache and a severe or unusual one should not be treated as the same situation. The most useful first step is deciding whether you need prompt assessment before trying to manage it at home.
Act on warning symptoms
Contact your maternity team or urgent medical service immediately for a severe headache, blurred vision or flashing lights, pain below the ribs, sudden swelling, or feeling very unwell. These can be signs of preeclampsia and need checking.
The preeclampsia guide explains why an earlier normal blood pressure reading does not replace assessment of new symptoms. Do not wait for all warning signs to appear together.
Explain what is different
Tell the clinician when the pain began, whether it came on suddenly, how intense it is, and whether it resembles headaches you have had before. Mention fever, vomiting, visual changes, weakness, or other new symptoms. A headache that starts suddenly and is extremely painful needs emergency help. So does a headache with a seizure, new weakness or numbness, difficulty speaking or walking, loss of vision, confusion, or marked drowsiness. A very high fever, stiff neck or a rash that does not fade under pressure also needs emergency assessment. Call your local emergency number or go to an emergency department; do not drive yourself.
If you have migraine, say which treatment you normally use. Pregnancy is a reason to review that plan rather than assume every new headache is your usual migraine.
Check pain relief with a professional
Paracetamol is usually the first choice for pain relief during pregnancy. Ask your pharmacist or clinician about suitability and dose, and use it for the shortest time needed. Do not take ibuprofen or codeine products unless prescribed by a doctor. Check other pain medicines and combination products before using them.
Keep an updated list alongside your pregnancy medical history, including combination cold or headache products.
Support comfort after urgent causes are addressed
Regular fluids, rest, and enough sleep may help with some headaches. Note whether missed meals or a particular routine seems relevant without assuming a single trigger explains everything.
If headaches recur or you repeatedly need medicine, arrange a review. Ask what would require urgent contact and what can be discussed at a routine appointment.
