Escalate
Do not treat a first thunderclap headache, persistent focal deficit, meningism, papilloedema, impaired consciousness, pregnancy-associated severe headache or a major change from the established pattern as routine migraine. Stabilise and investigate the secondary-headache emergency first.
Synopsis
Select safe, early and route-appropriate treatment for an individual migraine attack, add antiemetic support when useful, and prevent rescue therapy from creating medication-overuse headache.
Treat early in the headache phase when the diagnosis and pattern are secure; patients with aura usually take a triptan when headache begins rather than during aura alone.
NICE recommends combination therapy with an oral triptan plus an NSAID, or an oral triptan plus paracetamol, after discussing preference, comorbidity and adverse effects.
If one drug is preferred, offer an oral triptan, NSAID, aspirin 900 mg or paracetamol; aspirin is not for people under 16 and may be unsuitable in several adult contexts.
Key red flags
Triptan vascular risk
Known ischaemic heart disease, stroke, TIA, peripheral arterial disease or uncontrolled hypertension may contraindicate a triptan and should be checked before first prescription or renewal.
Investigation priorities
01
Treatment and attack timelineFirst step
Determine whether each medicine was taken early enough, at a therapeutic dose and by an absorbable route.
Management branches
First prescriptionCreate a usable attack plan
Migraine is diagnosed and acute treatment is required.
Confirm that the current episodes match a stable migraine phenotype and screen for urgent secondary features before discussing rescue medication.
Offer an oral triptan with an NSAID or paracetamol, or a suitable monotherapy option, after checking contraindications and the patient's preference.
Special contextAdapt treatment to risk
Pregnancy, vascular disease, renal or gastrointestinal disease, adolescence or complex polypharmacy changes routine choice.
Key medicines
Sumatriptan oralUsually 50 mg at headache onset; some require 100 mg, with one repeat after at least 2 hours if pain recurs, maximum 300 mg daily.
RimegepantFor an eligible adult, use 75 mg as an orodispersible tablet when needed, no more than once daily, following the commissioned formulary and current product information.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
