Migraine: What the Pharmacist Should Know
PharmaSim · Created · Updated
Educational material; no clinical peer review is claimed. Methodology and limitations
Migraine is a common, often disabling headache disorder that pharmacists encounter frequently. The role is to recognise it, offer appropriate OTC options, counsel on triggers, and spot the red flags that warrant referral. This article is educational and does not replace formal clinical training.
Why this matters in pharmacy
Migraine is under-recognised and often self-managed suboptimally. Many patients do not realise their headaches are migraines and treat them with general painkillers that may not work well. The pharmacist is often the first point of contact for accurate recognition and advice.
What distinguishes migraine from a common headache
Migraine is typically one-sided, pulsating, moderate to severe, and accompanied by sensitivity to light or sound, nausea, or visual disturbance (aura). A general tension headache is usually bilateral, pressing, and milder. The distinction matters because treatment differs.
OTC options and their limits
For mild to moderate migraine, paracetamol or an NSAID (ibuprofen, naproxen) at adequate dose early in the attack is first-line. Combination products with caffeine can help some patients. For severe migraine, OTC options are often insufficient and a triptan (prescription) may be needed. Taking medication too frequently can cause medication-overuse headache.
Triggers and lifestyle
Common triggers include stress, sleep changes, skipping meals, certain foods, and hormonal changes. Identifying and managing triggers is part of long-term care. A headache diary can help.
Red flags that need referral
These signs warrant urgent referral, not OTC advice: a sudden severe headache (thunderclap), headache with fever and neck stiffness, neurological symptoms, a new or changing headache pattern, or headache after head injury. These are not migraine variants; they are emergencies or review triggers.
Before calling the headache migraine
Establish onset, progression, prior diagnosis, associated symptoms and frequency. Ask about head injury, pregnancy or recent delivery, fever, new visual changes and neurological deficits. A familiar migraine pattern can still coexist with a new dangerous feature. Sudden severe headache, meningism, new weakness or speech disturbance needs emergency assessment. A first or substantially changed headache needs medical review rather than a confident diagnosis at the counter.
Medication-overuse risk is specific
Count days of use per month, not just tablets per day. NICE describes concern with triptans, opioids or combination analgesics on at least 10 days per month, or paracetamol, aspirin or NSAIDs on at least 15 days per month, for three months or more. This is not a diagnosis based on three days of use. A diary helps distinguish frequent attacks from frequent treatment and informs a clinician-led plan.
Choosing relief and setting a boundary
For an established migraine without new red flags, confirm contraindications before considering an OTC analgesic and follow the local product label. NSAIDs may be unsuitable with pregnancy, bleeding risk, ulcer disease or kidney impairment. Increasing the strength without assessing the pattern may perpetuate harm. Explain expected response, when to seek review and why a preventive-treatment discussion may be more useful than repeated rescue medication.
Practical example
A 'usual headache' that is a migraine
A patient asks for 'the strongest painkiller' for a one-sided, throbbing headache with nausea and light sensitivity. The pharmacist recognises migraine, not a tension headache, and counsels that an NSAID at adequate dose early in the attack is more effective than a weak general painkiller taken late. They advise on triggers and on when to see a prescriber for a preventive plan if attacks are frequent. The patient leaves with a better-matched treatment and a plan.
Key takeaways
- Migraine is one-sided, pulsating, with sensory sensitivity and nausea; a tension headache is bilateral and milder.
- Early, adequate-dose NSAIDs or paracetamol are first-line for mild to moderate migraine; severe attacks may need a triptan.
- Too-frequent analgesic use causes medication-overuse headache.
- Sudden severe, neurological, or fever-with-stiff-neck headaches are red flags for urgent referral.
