Headache in pregnancy treatment: what to know

Pregnancy can change sleep, eating patterns, hydration, posture, and sensitivity to stress. Headache may also accompany a cold, nasal inflammation, heat exhaustion, or dehydration. A headache does not by itself identify one cause. The timing, location, severity, associated symptoms, and your stage of pregnancy help a clinician decide what to check.

Sip water regularly, eat a balanced snack if you have missed a meal, and rest in a quiet, dim room. A cool cloth on the forehead or gentle neck relaxation may help. Keep a brief record of onset, duration, triggers, and any visual symptoms. Do not start, stop, or combine pain medicines without checking with your maternity clinician or pharmacist; some medicines are unsuitable in pregnancy.

Contact your maternity team promptly for a severe, persistent, sudden, or unfamiliar headache, especially with blurred vision, flashing lights, swelling, upper abdominal pain, vomiting, breathlessness, weakness, confusion, fever, or a stiff neck. Seek emergency help for collapse, a seizure, new trouble speaking, or one-sided weakness. These warning signs require assessment rather than home treatment.

Ask which pain reliever and dose fit your pregnancy, whether your blood pressure needs checking, and which symptoms should prompt same-day review. Mention every medicine, supplement, and remedy you use, plus any history of migraine or high blood pressure.
