One-liner#

Adult/geriatric outpatient approach to headache: screen for secondary red flags (SAH, meningitis, mass, GCA), then treat common primary headaches with clear follow-up and return precautions.

Quick nav#

Red flags / send to ED#

  • Thunderclap: sudden severe “worst headache,” peak in <1 minute (possible SAH)
  • New headache with focal neuro deficit, altered mental status, or seizure
  • Fever + neck stiffness/photophobia (possible meningitis/encephalitis)
  • New headache with papilledema, persistent vomiting, or worse lying down/with Valsalva (possible increased ICP)
  • Age >50 with new headache, jaw claudication, vision changes, scalp tenderness (possible GCA)
  • Immunosuppression, cancer, or pregnancy/postpartum (out of scope by default) with new severe headache
  • New severe headache after head trauma or while anticoagulated (follow local protocol)
  • “Worst headache of life” with exertion/sex trigger, collapse, or persistent vomiting (treat as thunderclap until proven otherwise)

Key history#

  • Onset: sudden vs gradual; first/worst vs recurrent; change from baseline pattern
  • Time course: minutes/hours/days; episodic vs daily; duration of attacks
  • Location/quality: unilateral vs bilateral; throbbing vs pressure; “band-like”
  • Associated symptoms: nausea/vomiting, photophobia/phonophobia, aura, autonomic symptoms (tearing/congestion), neck pain
  • Triggers: missed meals/sleep, dehydration, stress, exertion, alcohol, posture
  • Medication use: how often using NSAIDs/acetaminophen/caffeine/triptans (medication-overuse risk)
  • Risk factors: vascular risk, cancer, immunosuppression; temporal symptoms (GCA screen)
  • Headache “phenotype” questions that change management:
    • Migraine: worsened by activity, nausea, photo/phonophobia, prefers dark room
    • Cluster: severe unilateral with tearing/congestion, pacing, short attacks, circadian pattern
    • Secondary: new pattern in older adult; persistent progressive worsening; positional/Valsalva triggers

Focused exam#

  • Vitals (fever, BP), general appearance
  • Neuro screen: mental status, speech, pupils, EOM, facial symmetry, limb strength/sensation, gait
  • Fundoscopy if feasible (papilledema)
  • Meningeal signs when indicated
  • Temporal artery tenderness + jaw symptoms when GCA suspected
  • Sinus/ENT and neck exam if indicated
  • Neck ROM and focal tenderness if cervicogenic pattern suspected (also see Neck pain)

Workup#

  • No imaging for typical recurrent migraine/tension headache with a normal neuro exam and no red flags.
  • If red flags or abnormal neuro exam: ED pathway and imaging per protocol.
  • Consider imaging/urgent evaluation for a new cluster-like phenotype in an older patient, atypical features, or abnormal exam.
  • For suspected GCA: ESR/CRP and same-day evaluation per local protocol (do not delay if vision symptoms).
  • Consider targeted labs only when indicated (e.g., infection concern, metabolic triggers).
  • Do not use sinus imaging for uncomplicated “sinus pressure” headaches without concerning features; treat based on the clinical syndrome.

Initial management#

  • Treat pain early and adequately; ensure hydration, sleep, and trigger avoidance plan.
  • Avoid escalating to opioids; reassess diagnosis if pain is severe and out of proportion.
  • If headaches are frequent, address prevention and medication-overuse risk.
  • Set a simple “if/then” rescue plan and a follow-up interval so patients don’t keep cycling through urgent care.

Management by diagnosis#

Migraine#

Education:

  • Early treatment is more effective; take medication at first sign of headache, not after it’s severe
  • Limit rescue meds to ≤10 days/month (triptans) or ≤15 days/month (NSAIDs) to avoid medication-overuse headache
  • Identify and avoid triggers (sleep disruption, dehydration, skipped meals, alcohol, stress)
  • Consider vestibular migraine if dizziness is a major feature (see Dizziness / vertigo)

Treatment—Acute:

DrugDoseContraindicationsMonitoringCostNotes
Sumatriptan50–100 mg PO; may repeat x1 after 2h (max 200 mg/day)CAD, uncontrolled HTN, stroke/TIA, hemiplegic migraine, MAOIsCV symptoms$First-line triptan; also available as nasal spray (20 mg) or injection (6 mg SC). No renal adjustment needed.
Rizatriptan5–10 mg PO; may repeat after 2h (max 30 mg/day)Same as sumatriptan; reduce dose with propranololCV symptoms$Fast onset; 5 mg if on propranolol
Naproxen500–750 mg PO at onsetGI bleed, CKD (avoid if eGFR <30), CV diseaseCr if frequent use$Good first-line; can combine with triptan
Ibuprofen400–800 mg PO at onsetSame as naproxenSame$Alternative NSAID; avoid in CKD
Metoclopramide10 mg PO/IV with analgesicParkinson’s, tardive dyskinesiaEPS with repeated use$Antiemetic + enhances analgesic absorption
Acetaminophen + caffeine1000 mg + 130 mg (e.g., Excedrin)Liver disease; limit caffeine if frequentCaffeine overuse$OTC option; watch for medication-overuse; safe in CKD

Menstrual migraine: if predictable, consider scheduled NSAID or triptan starting 2 days before expected menses through day 3.

Treatment—Preventive (consider if ≥4 headache days/month or significant disability):

DrugDoseContraindicationsMonitoringCostNotes
Propranolol40–160 mg/day (start 20 mg BID)Asthma, bradycardia, decompensated HFHR, BP$First-line; also helps anxiety; avoid abrupt discontinuation. Good in elderly if no bradycardia.
Topiramate25–100 mg/day (start 25 mg QHS, titrate weekly)Kidney stones, glaucoma, pregnancyCognitive SE, weight, bicarb$Weight loss effect; teratogenic—requires contraception. Avoid in elderly (cognitive SE).
Amitriptyline10–50 mg QHS (start 10 mg)Glaucoma, urinary retention, cardiac conduction diseaseAnticholinergic SE; ECG if cardiac hx$Good if insomnia or tension-type overlap. Caution elderly (anticholinergic, falls). Start 10 mg in elderly.
Venlafaxine75–150 mg/dayUncontrolled HTN, MAOIsBP$Alternative if depression/anxiety comorbid
Magnesium oxide400–500 mg dailyRenal impairment (avoid if eGFR <30)Diarrhea$Low risk; modest evidence; good adjunct. Reduce dose in CKD.
Riboflavin (B2)400 mg dailyNoneNone$Takes 3 months for effect; very safe; good option in elderly/CKD

Elderly patients: prefer propranolol (if no bradycardia), magnesium, or riboflavin. Avoid topiramate (cognitive) and use low-dose TCAs cautiously (anticholinergic burden, falls).

CGRP inhibitors (erenumab, fremanezumab, galcanezumab): specialist-initiated; consider referral if 2+ preventives fail.

Follow-up: 4–6 weeks to assess acute therapy; 8–12 weeks to assess preventive efficacy. Earlier if new neuro symptoms, change in pattern, or poor control.

Tension-type headache#

Education:

  • Often linked to sleep deprivation, stress, poor posture, or eye strain
  • Headaches should gradually improve with lifestyle changes
  • Frequent analgesic use can paradoxically worsen headaches

Treatment:

DrugDoseContraindicationsMonitoringCostNotes
Ibuprofen400–600 mg PRN (max 2400 mg/day)GI bleed, CKD, CV diseaseCr if frequent$First-line; limit to ≤15 days/month
Acetaminophen650–1000 mg PRN (max 3 g/day)Liver disease, alcohol useLFTs if prolonged$Alternative if NSAIDs contraindicated
Naproxen250–500 mg BID PRNSame as ibuprofenSame$Longer duration of action

Preventive (if ≥15 days/month or chronic):

DrugDoseContraindicationsMonitoringCostNotes
Amitriptyline10–50 mg QHSGlaucoma, urinary retention, cardiac diseaseAnticholinergic SE$First-line preventive; helps sleep
Nortriptyline10–50 mg QHSSame as amitriptylineSame$Less sedating than amitriptyline

Follow-up: 4–6 weeks if persistent or frequent; address sleep, stress, ergonomics.

Cluster headache (suspected)#

Education:

  • Severe unilateral headaches with autonomic symptoms (tearing, nasal congestion, ptosis) lasting 15–180 minutes
  • Attacks often occur at same time daily, frequently at night; cluster periods last weeks to months
  • Time-sensitive treatment can abort attacks; preventive therapy shortens cluster periods

Treatment—Acute (abortive):

DrugDoseContraindicationsMonitoringCostNotes
High-flow O212–15 L/min via non-rebreather x 15–20 minNoneNone$$First-line; 70% effective; requires Rx for home O2
Sumatriptan SC6 mg SC; may repeat x1 after 1hCAD, uncontrolled HTN, strokeCV symptoms$$Fastest triptan onset; preferred over oral
Sumatriptan nasal20 mg; may repeat after 2hSame as SCSame$Alternative if injection refused
Zolmitriptan nasal5 mg; may repeat after 2hSameSame$$Alternative nasal triptan

Treatment—Preventive (bridge/transitional):

DrugDoseContraindicationsMonitoringCostNotes
Verapamil240–480 mg/day in divided doses (start 80 mg TID)Heart block, severe HF, concurrent beta-blockerECG at baseline and with dose increases$First-line preventive; may need high doses
Prednisone60–80 mg/day x 5 days, then taper over 2–3 weeksActive infection, uncontrolled DMGlucose, mood$Bridge therapy while verapamil titrated

Neurology referral recommended for all suspected cluster headache; specialist may add lithium, topiramate, or occipital nerve block.

Follow-up: within 1 week; urgent neurology referral.

Medication-overuse headache#

Education:

  • Frequent rescue meds (≥10–15 days/month) can perpetuate daily headaches
  • Withdrawal may temporarily worsen headaches for 1–2 weeks before improvement
  • Prevention is key: limit acute meds and optimize preventive therapy

Treatment:

  • Structured taper of overused medication over 2–4 weeks
  • Bridge therapy during withdrawal:
DrugDoseContraindicationsMonitoringCostNotes
Naproxen (scheduled)500 mg BID x 2–4 weeksGI bleed, CKD, CV diseaseGI symptoms$Bridge if overusing triptans or combination analgesics
Prednisone60 mg x 5 days, taper over 1 weekActive infection, uncontrolled DMGlucose$Short bridge for severe withdrawal
  • Start or optimize preventive therapy (see Migraine preventives above)
  • Consider neurology referral if multiple failed attempts

Follow-up: 2–4 weeks during taper; close support improves success.

Cervicogenic headache#

  • Education: treating the neck source improves headaches.
  • Treatment: PT/manual therapy as appropriate, ergonomics, sleep positioning; analgesics/topicals as needed; coordinate with Neck pain.
  • Follow-up: 4–6 weeks.

Suspected GCA (age >50 + compatible symptoms)#

Education:

  • Vision loss risk makes this time-sensitive; permanent blindness can occur within hours to days
  • Treatment should not be delayed for biopsy results

Treatment:

  • If vision symptoms present: start prednisone 60 mg daily immediately and arrange same-day ophthalmology/rheumatology evaluation
  • If no vision symptoms: start prednisone 40–60 mg daily and arrange urgent evaluation within 24–48 hours
  • Order ESR and CRP (both elevated supports diagnosis; normal does not exclude)
  • Temporal artery biopsy should be arranged but does not delay treatment

Follow-up: urgent same-day if vision symptoms; within 24–48 hours otherwise. Rheumatology to manage long-term.

Follow-up#

  • Reassess in 2–4 weeks if headaches are frequent, worsening, or require a prevention plan.
  • Reassess in 4–6 weeks for typical migraine/tension once a plan is started.
  • Escalate urgently for thunderclap onset, fever/neck stiffness, new neuro deficits, vision changes, or rapidly worsening pattern.
  • If not improving after 4–6 weeks (or increasing frequency), escalate (optimize prevention, address medication-overuse, and reconsider secondary causes/imaging thresholds).

Patient instructions#

  • Treat early at the start of a headache and stay hydrated; prioritize sleep and regular meals.
  • Limit rescue medication use to avoid rebound headaches (follow the plan you were given).
  • Avoid opioids for headaches unless specifically directed by your clinician.
  • Track frequency/triggers and bring the log to follow-up.
  • Seek urgent care now for a sudden “worst headache,” fever with stiff neck, new weakness/numbness, confusion, or vision changes.
