Migraine affects approximately 10 million people in the United Kingdom, according to the Migraine Trust, making it the third most prevalent disease globally after dental caries and tension-type headache. It is a leading cause of disability in working-age adults, and the majority of people with migraine manage their condition with over-the-counter medicines purchased from community pharmacies.

The reclassification of sumatriptan 50mg to pharmacy supply (P medicine) in 2006 was a landmark for migraine management in the UK. Community pharmacists can now supply a triptan — the gold-standard acute treatment — without a prescription, placing pharmacy at the centre of migraine care.

Acute treatment: the stepped approach

NICE guideline CG150 on headaches recommends a stepped approach to acute migraine treatment. The pharmacist's role is to match treatment to attack severity and to identify patients who may benefit from prescription options.

Step 1: Simple analgesics

Key pharmacist advice: Take analgesics as early as possible in the attack — absorption slows during migraine due to gastric stasis. Combination with an anti-emetic (domperidone 10mg, prescription required; or prochlorperazine buccal 3mg, OTC as Buccastem M) can improve efficacy by promoting gastric emptying.

Step 2: Triptan (pharmacy supply)

Pharmacy supply criteria (checklist):

• Patient aged 18–65
• Previously diagnosed with migraine by a doctor
• Typical attacks last 4–72 hours untreated
• No cardiovascular disease, uncontrolled hypertension, or history of stroke/TIA
• Not currently on ergotamine, other triptans, SSRIs/SNRIs (serotonin syndrome risk — low but flagged in SPC), or MAOIs
• Not pregnant or breastfeeding

Step 3: Prescription options

For patients not responding to OTC sumatriptan, pharmacists should recommend GP review for:

• Higher-dose sumatriptan (100mg) or alternative triptans (rizatriptan, zolmitriptan, almotriptan)
• Triptan plus NSAID combination therapy
• Prophylactic treatment if attacks occur on four or more days per month

Medication overuse headache: the pharmacy's critical role

Medication overuse headache (MOH) is one of the most important conditions for community pharmacists to recognise. It occurs when acute headache medicines — including triptans, codeine-containing analgesics, and even simple paracetamol — are used on 10–15 or more days per month for three consecutive months.

The result is a paradoxical increase in headache frequency, creating a cycle where the patient takes more of the medicine that is causing the problem. MOH affects approximately 1–2% of the general population.

Red flags for MOH at the pharmacy counter

• Patient requesting OTC analgesics or sumatriptan more than twice per week
• Patient buying codeine-containing products (co-codamol, Nurofen Plus, Solpadeine) regularly
• Patient reporting that their headaches are getting more frequent despite regular painkiller use
• Patient describes a daily or near-daily background headache with superimposed more severe attacks

Pharmacists should sensitively counsel patients about the link between frequent analgesic use and worsening headaches, and refer to their GP for a structured withdrawal plan. NICE CG150 specifically identifies pharmacy as a key setting for MOH identification.

Anti-emetics for migraine

Nausea and vomiting are prominent features of migraine for many patients. Available OTC options:

For patients who vomit early in attacks, non-oral formulations are essential. Sumatriptan is also available as a nasal spray (prescription) and injection (prescription) for patients who cannot retain oral medication.

Lifestyle advice

Evidence-based advice pharmacists can offer:

• Identify triggers: common triggers include stress, irregular sleep, skipped meals, dehydration, alcohol (especially red wine), bright/flickering lights, and hormonal changes
• Keep a headache diary: record attack frequency, duration, possible triggers and medicines used — essential for identifying MOH and informing preventive treatment decisions
• Regular sleep and meals: the migraine brain dislikes change. Regular sleep-wake cycles and regular meals are protective
• Hydration: dehydration is a common and preventable trigger
• Exercise: regular moderate exercise reduces migraine frequency, according to evidence cited in NICE CG150

When to refer

Pharmacists should refer urgently when:

• Sudden-onset severe headache (thunderclap headache) — possible subarachnoid haemorrhage. Call 999
• Headache with fever, neck stiffness and photophobia — possible meningitis
• New headache with neurological signs (weakness, speech difficulty, visual loss)
• Headache worsening progressively over weeks
• First migraine after age 50
• Migraine with prolonged aura (lasting more than 60 minutes)

The pharmacy opportunity

Migraine management is one of the clearest examples of pharmacy operating as a first-contact clinical service. The pharmacist can supply the most effective acute treatment (sumatriptan), counsel on optimal use, screen for MOH, and identify patients who need preventive therapy or urgent referral.
