I now have strong textbook evidence to give a thorough clinical response. Here is the full assessment:

Clinical Assessment: 19-Year-Old Female with Headache, Bilious (Yellow) Vomiting, and Abdominal Pain

Most Likely Diagnosis: Migraine (with prominent nausea/vomiting)

This is the top differential given:

Young female (migraine is 3x more common in women, often beginning in adolescence/young adulthood)
Headache + nausea + multiple vomiting episodes
Unable to eat (anorexia during attack is classic)
Abdominal pain with vomiting (visceral symptoms of migraine)
Yellow/bilious vomit = bile-stained vomit that occurs when the stomach empties completely and bile refluxes - this is common after multiple vomiting episodes, NOT necessarily a sign of obstruction in this context

As per Bradley and Daroff's Neurology in Clinical Practice: "Nausea is present during the migraine attack in the majority of patients and vomiting occurs in about half. Vomiting can complicate the migraine attack by leading to dehydration and preventing the absorption of orally administered medications."

The POUND mnemonic for migraine diagnosis:

P - Pulsatile quality
O - One-day duration (4-72 hours)
U - Unilateral location
N - Nausea or vomiting ✓
D - Disabling intensity

Differential Diagnoses to Consider

Condition	Key Features	Red Flags?
Migraine (most likely)	Young female, headache + vomiting + abdominal pain	None unless new or "worst headache ever"
Abdominal migraine	Recurrent abdominal pain + nausea/vomiting + headache	No
Increased Intracranial Pressure	Headache + projectile vomiting, especially morning	Yes - needs urgent workup
Gastroenteritis	Abdominal cramps, vomiting, possibly diarrhea	No
Peptic ulcer / gastritis	Epigastric pain, vomiting	No
Subarachnoid hemorrhage	Sudden-onset "thunderclap" worst headache of life	YES - emergency
Meningitis	Fever + neck stiffness + headache + vomiting	YES - emergency

Red Flag "SNNOOP" Features to Rule Out (Ask / Examine For)

Ask about and examine for:

Sudden onset ("worst headache of my life", thunderclap) - SAH
Neurological symptoms - focal weakness, vision changes, altered consciousness - mass lesion, stroke
New headache in a patient over 50 (N/A here, but note)
Onset with exertion, cough, Valsalva - intracranial hypertension
Orthostatic component
Fever + neck stiffness - meningitis/encephalitis
Papilledema on fundoscopy - raised ICP
Progressive worsening despite treatment

If NONE of these are present, this is likely a primary headache disorder (migraine).

Immediate Management (Emergency Department / Acute Setting)

Step 1 - Assess hydration status - multiple vomiting episodes risk dehydration; she is unable to eat.

Step 2 - IV/IM Antiemetics (First-line for acute migraine with vomiting):

Per Rosen's Emergency Medicine: Dopamine antagonists are first-line for acute migraine in the ED:

Metoclopramide 10 mg IV over 15-30 min (antiemetic + antimigraine)
Prochlorperazine 10 mg IV/IM (highly effective monotherapy)
Pre-treat with diphenhydramine 25-50 mg IV to prevent akathisia (extrapyramidal side effects)

Step 3 - IV Fluid Hydration (normal saline) if dehydrated

Step 4 - Pain relief:

NSAIDs - Ibuprofen, Ketorolac 15-30 mg IV/IM (once nausea controlled and no contraindications)
Triptans (sumatriptan) - for moderate-to-severe migraine; available SC/intranasal if vomiting prevents oral intake. Do a pregnancy test first before using triptans.
Avoid opioids (associated with worse outcomes in migraine, medication overuse headache)

Step 5 - Dark, quiet environment - rest, reduce sensory stimuli

Investigations to Order

Blood glucose - rule out hypoglycemia causing headache/vomiting
Urine pregnancy test - mandatory in any female of reproductive age before medications
Electrolytes / renal function - if significant vomiting/dehydration
CBC - if fever or infection suspected
CT head - ONLY if red flags are present (thunderclap onset, focal neuro signs, fever, papilledema, trauma history)
Lumbar puncture - if CT normal but SAH or meningitis still suspected

Key Teaching Points

Bilious (yellow-green) vomit after multiple episodes simply means the stomach is empty and bile is refluxing - it does not necessarily mean bowel obstruction in this context. However, persistent bilious vomiting with abdominal distension would warrant surgical evaluation.
Gastric stasis is common during migraine - oral medications are poorly absorbed. IV/IM route is preferred during acute attacks. - Rosen's Emergency Medicine
Migraine in young women is often menstrually-related; ask about the timing relative to her menstrual cycle.
If this is a first-ever headache of this severity, or the pattern is different from previous headaches, brain imaging is indicated regardless of age.

I now have excellent textbook content to give a detailed updated assessment. Here is the revised clinical picture:

Updated Assessment - Critical New Information: Visual Loss Before Headache

The history of visual loss preceding headache, occurring in multiple episodes over a week, changes and sharpens the differential significantly.

Top Two Diagnoses to Differentiate Urgently

1. Migraine with Aura (Most Likely)

This pattern is classic. Per Neuroanatomy through Clinical Cases:

"Migraine often is preceded by an aura or warning symptoms, classically involving visual blurring, shimmering, scintillating distortions, or fortification scotoma - a characteristic region of visual loss bordered by zigzagging lines resembling the walls of a fort."

How the visual aura fits:

Visual symptoms (loss, blurring, flashes, zigzag lines) lasting 5-60 minutes
Followed by headache within 60 minutes
Then nausea and vomiting
Resolves completely between attacks (no permanent visual loss)
Recurrent episodes over a week - fits the pattern of repeated migraine attacks

Key features of aura:

Spreads gradually over >5 minutes
Usually binocular (both eyes - cortical origin, occipital cortex)
Fully reversible
May include visual, sensory, or speech symptoms

2. Idiopathic Intracranial Hypertension (IIH) / Pseudotumor Cerebri - Must Not Miss

Per Tintinalli's Emergency Medicine:

"The most prominent symptoms include headache (84%), transient visual obscurations (68%), back pain (53%), and pulsatile tinnitus (52%). Untreated, IIH can lead to permanent visual impairment if not recognized."

Why IIH must be considered in this patient:

Young female (exact demographic - 19-year-old woman)
Recurrent headache + transient visual loss = the hallmark presentation
Transient visual obscurations in IIH are typically brief (seconds), triggered by posture change or Valsalva
Associated with nausea and vomiting from raised ICP
Risk of permanent blindness if untreated

IIH Diagnostic Criteria (Modified Dandy):

Criterion	Finding Needed
Symptoms of raised ICP	Headache, visual symptoms ✓
No focal neurological signs	Normal exam (except papilledema, CN VI palsy)
Elevated opening pressure	>25 cm H₂O on LP
Normal CSF composition	No cells, normal protein
Normal neuroimaging	CT/MRI: no mass, no hydrocephalus

Other "Must Not Miss" Diagnoses

3. Cerebral Venous Sinus Thrombosis (CVST)

Young women are at higher risk (especially if on oral contraceptive pills - ask!)
Presents with progressive headache + visual symptoms + raised ICP features
Can mimic IIH
Diagnosis: MRI with MR venography

4. Posterior Circulation TIA / Stroke

Visual loss + headache from vertebrobasilar territory ischemia
Less likely at age 19, but must consider if visual loss was complete/monocular, abrupt, and associated with other posterior circulation signs (diplopia, ataxia, dysarthria)

5. Retinal Migraine

Monocular visual loss (one eye only) before or during headache
Important because it carries a small risk of retinal ischemia
Diagnosis of exclusion - requires ophthalmology review

Urgent Questions to Ask This Patient RIGHT NOW

Was the visual loss in one eye or both eyes? (Monocular = retinal/ophthalmic artery; Binocular = cortical/occipital = aura)
What did the visual loss look like? - Total blackout? Zigzag lights? Shimmering? Blurring? (Flashing lights/zigzags = typical aura; grey-out/blackout = IIH obscuration or retinal)
How long did the visual loss last? - Seconds (IIH obscuration) vs. minutes (migraine aura, TIA)
Is she on the oral contraceptive pill or any hormonal contraception? (CVST risk)
Any pulsatile tinnitus (whooshing sound in ears)? (IIH hallmark)
Any double vision? (CN VI palsy in IIH)
Does headache worsen when lying down or in the morning? (raised ICP pattern)
Any recent weight gain? (IIH risk factor)
Any neck stiffness or fever? (meningitis)
Is the headache the worst she has ever had? (SAH red flag)

Urgent Investigations to Order NOW

Investigation	Reason
Fundoscopy (ophthalmoscopy)	Look for papilledema - most important single bedside test; present in IIH
CT head (without contrast)	Rule out mass, bleed, hydrocephalus before LP
MRI brain + MR Venography	Rule out CVST, posterior fossa lesion, cortical lesion
Lumbar puncture (after imaging is clear)	Measure opening pressure - diagnostic for IIH if >25 cm H₂O
Pregnancy test	Mandatory before treatment in reproductive-age female
Ophthalmology review	Formal visual field testing, visual acuity, retinal exam
CBC, CMP, electrolytes	Dehydration from vomiting, infection screen

Treatment Priorities

If IIH is confirmed:

Acetazolamide (carbonic anhydrase inhibitor) - reduces CSF production, first-line
Weight loss counseling if overweight
Therapeutic LP - immediate CSF pressure relief
Ophthalmology follow-up mandatory (risk of optic nerve damage)
If refractory: optic nerve sheath fenestration or CSF shunting

If Migraine with Aura is confirmed:

Acute: Triptans + antiemetics (as discussed previously)
Important: Triptans and combined oral contraceptives are relatively contraindicated in migraine with aura due to increased stroke risk
Preventive therapy: propranolol, topiramate, amitriptyline
Avoid OCP if she is on it

Bottom Line

This patient has recurrent headache + visual loss + vomiting in a young female. While migraine with aura is the most likely diagnosis, IIH and CVST must be excluded urgently because both can cause permanent visual loss or stroke if missed. Fundoscopy and neuroimaging are non-negotiable next steps.

Disclaimer: This is for educational/clinical decision support only. All management decisions must be made by a qualified clinician with full examination findings.

She does not have any neck stiffness the vision loss starts as a tiny spot and then complete vision loss for minutes and the headache is generally on one sid3 pain radiating from the ocular margins to the back of the head

Now I have everything needed for a precise, detailed answer. This clinical picture is now remarkably specific.

Updated Diagnosis: Migraine with Visual Aura - High Confidence

The new details lock this in with high specificity:

Why This is Classic Migraine with Aura - Pattern Analysis

The Visual Symptom Sequence is Textbook

The patient describes:

"Vision loss starts as a tiny spot, then complete vision loss for minutes"

This is a negative expanding scotoma - one of the most characteristic features of migraine aura. This is caused by cortical spreading depression (CSD), a slow wave of neuronal depolarization that spreads across the occipital cortex at ~3 mm/minute.

Per Bradley and Daroff's Neurology in Clinical Practice:

"The aura in migraine typically lasts 5-60 minutes, reflecting that cortical spreading depression (the main pathophysiology of migraine) results from a slow depolarization that spreads at about 3 mm/min."

Per Neuroanatomy through Clinical Cases:

"Migraine aura classically involves visual blurring, shimmering, scintillating distortions, or fortification scotoma - a characteristic region of visual loss bordered by zigzagging lines resembling the walls of a fort."

The key visual aura types:

Type	Description	This Patient
Scintillating scotoma	Expanding arc of shimmering zigzag lines surrounding a blind spot	Closest match
Negative scotoma	Expanding area of visual loss, no flicker	Also fits
Fortification spectrum	Zigzag angular lines at edge of blind area	Classic form

The evolution from small central spot → expanding to complete loss over minutes = the classic slow centrifugal spread of CSD through the occipital cortex.

The Headache Pattern is Textbook

"Unilateral, radiating from the ocular margins to the back of the head"

This is the exact anatomical pain distribution of migraine:

Periorbital/retro-orbital onset = trigeminal pain from ophthalmic division (V1), activation of the trigeminovascular system
Radiating to the occiput = pain spreads along the trigeminal-cervical complex (connections between CN V spinal nucleus and C1-C3 dorsal horn)
Unilateral = classic hemicranial distribution ("migraine" = hemi-crania = half the skull)

The sequence is also classic: Visual aura → followed by ipsilateral unilateral throbbing headache → nausea/vomiting

Confident Diagnosis: Migraine with Typical Visual Aura (ICHD-3 Code 1.2.1)

ICHD-3 Diagnostic Criteria Met:

Criterion	Requirement	Patient
A	≥2 attacks	2-3 episodes in 1 week ✓
B	Aura: ≥1 visual symptom	Expanding scotoma → complete visual loss ✓
C	Aura: fully reversible	Vision returns (implied) ✓
D	Aura: develops over ≥5 min	Small spot → complete loss over minutes ✓
E	Aura: lasts 5-60 min	Minutes (fits) ✓
F	Headache follows within 60 min	Yes ✓
G	Not better explained by another diagnosis	No fever, no neck stiffness, no focal neuro signs ✓

What to Do Now - Step-by-Step Plan

Immediate (Today)

1. Fundoscopy - Still essential to rule out papilledema (IIH can mimic, though less likely now)

2. Ask: Is she on the oral contraceptive pill?

This is CRITICAL - per Bradley and Daroff's:

"The risk for ischemic stroke was particularly increased in women with migraine who were using oral contraceptives (OR = 13.9)... Women with migraine with aura who use OCPs have an incidence of ischemic stroke of 28-78 per 100,000."

Migraine with aura + OCP = major stroke risk - she must stop it if she is using it.

3. Establish whether she smokes - migraine with aura + OCP + smoking = OR 10.2 for stroke

Acute Attack Treatment (Right Now)

She has active headache + vomiting and cannot eat, so oral medications are unreliable:

Drug	Route	Dose	Purpose
Metoclopramide	IV/IM	10 mg	Antiemetic + antimigraine + enhances absorption
Diphenhydramine	IV	25-50 mg	Pre-treatment to prevent akathisia
Ketorolac	IV/IM	15-30 mg	Pain relief (NSAID)
OR Sumatriptan	SC/nasal	6 mg SC or 20 mg nasal	Triptan (do pregnancy test first)
IV Normal Saline	IV	500-1000 mL	Rehydration (vomiting + cannot eat)

Note: Triptans work best if given early in the attack, ideally at aura onset or early headache. They are less effective once headache is well-established. - Rosen's Emergency Medicine

Outpatient Follow-Up (Must Arrange)

1. Preventive (prophylactic) therapy - she has had 2-3 attacks in one week, which meets criteria for prevention:

Drug	Notes
Propranolol 40-120 mg/day	First-line beta-blocker
Topiramate 25-100 mg/day	First-line, effective but causes cognitive side effects
Amitriptyline 10-75 mg at night	Especially if sleep-related triggers
Valproate/Divalproex	Effective but avoid in women of childbearing age (teratogenic)

2. Neurology referral - for formal diagnosis, preventive plan, and to exclude CVST/IIH with MRI

3. MRI Brain (outpatient if no red flags on exam) - baseline imaging is advisable for:

Frequent migraines in a young person
Aura always on the same side (warrants MRI to exclude AVM/vascular malformation)
Rule out posterior fossa lesion

4. Lifestyle/trigger identification:

Sleep regularity
Hydration
Meal timing (skipping meals = common trigger)
Stress management
Identify personal triggers (certain foods, lights, hormonal changes)

One Critical Warning to Give This Patient

"If the headache is sudden and severe - the worst headache of your life - or if the visual loss does not resolve, or if you develop weakness, slurred speech, or confusion during an episode - go to the emergency department immediately. These would require urgent CT scan."

This distinguishes the rare but life-threatening migrainous infarction or subarachnoid hemorrhage from typical migraine.

Summary: This is Migraine with Typical Visual Aura - small expanding scotoma progressing to complete visual loss for minutes, followed by unilateral retro-orbital to occipital headache, with nausea and bilious vomiting. No neck stiffness makes meningitis unlikely. Urgent: check OCP use (stroke risk), fundoscopy, and consider MRI. Treat acute attack with IV antiemetics + hydration + NSAID/triptan. Start prophylaxis given attack frequency.

Here is a thorough, evidence-based answer on ondansetron for this patient:

Ondansetron in Migraine with Vomiting - The Full Picture

What Ondansetron Is

Ondansetron (Zofran) is a selective 5-HT₃ (serotonin type 3) receptor antagonist. It blocks 5-HT₃ receptors in:

The chemoreceptor trigger zone (CTZ) in the area postrema
Peripheral vagal afferents in the GI tract

This makes it a highly effective antiemetic for many conditions.

The Core Problem: Ondansetron vs. Dopamine Antagonists in Migraine

This is a nuanced, important clinical question. The answer depends on what you want the drug to do:

Property	Ondansetron	Metoclopramide / Prochlorperazine
Antiemetic effect	✅ Good	✅ Excellent
Direct antimigraine effect	❌ None proven	✅ Yes - treats headache too
Improves gastric motility	❌ No	✅ Yes (metoclopramide)
Improves oral drug absorption	❌ No	✅ Yes
Side effects	Headache, constipation, QT prolongation	Akathisia, sedation, dystonia
First-line for migraine	❌ Not recommended	✅ Yes

Why Metoclopramide/Prochlorperazine Are Preferred Over Ondansetron in Migraine

Per Cummings Otolaryngology (citing clinical evidence):

"Migraine patients frequently experience nausea and vomiting and respond well to oral, rectal, or intravenous antiemetics; however, caution should be exercised while using ondansetron, because this frequently causes headaches, especially in children."

The key reasons dopamine antagonists are preferred in migraine:

They treat both the headache AND the vomiting - metoclopramide and prochlorperazine have direct central antimigraine mechanisms (dopaminergic pathway involvement in migraine pathogenesis)
Metoclopramide restores gastric motility - migraine causes gastric stasis, which traps oral medications. Metoclopramide reverses this and improves absorption of co-administered drugs
Ondansetron can paradoxically worsen or cause headache - possibly because blocking 5-HT₃ receptors peripherally may alter serotonergic tone in ways that aggravate migraine

The Evidence: Is Ondansetron Useless in Migraine?

Not entirely. A 2020 pediatric ED study (PMID 32433024) - Talai & Heilbrunn, Pediatric Neurology - found:

90% treatment success (≥50% pain score reduction) with ondansetron regimens
Comparable outcomes to antidopaminergic agents in pediatric ED patients
Conclusion: "Ondansetron may be a useful medication... preliminary data suggest it is comparable to antidopaminergic agents"

However this was:

Retrospective, pediatric data only
Not an RCT
A small sample (42 in ondansetron group)

The adult evidence is weaker and guideline bodies do not recommend ondansetron as first-line for migraine.

When Ondansetron IS Reasonable to Use in This Patient

Despite not being first-line, ondansetron is a practical and acceptable choice in certain situations:

✅ Severe refractory vomiting where stopping the vomiting itself is the immediate priority ✅ Metoclopramide/prochlorperazine not available in your setting ✅ Patient has history of dystonia or akathisia from dopamine antagonists ✅ Pregnancy (category B, safer profile) ✅ As adjunct when dopamine antagonists alone have not controlled vomiting ✅ Oral/sublingual route - ondansetron has an ODT (oral disintegrating tablet) form that dissolves under the tongue, useful when IV access is not available and the patient is vomiting

Practical Dosing for This 19-Year-Old

Route	Dose	Notes
IV	4-8 mg over 15 min	Slow infusion reduces headache risk
IM	4-8 mg	If no IV access
ODT (sublingual)	4-8 mg	Excellent for vomiting patients - dissolves without swallowing

Give slowly - rapid IV push increases the chance of headache and QT prolongation.

Recommended Approach for THIS Patient

Given she has migraine with aura + active vomiting + cannot eat:

Best regimen:

Metoclopramide 10 mg IV (first choice - treats both headache and vomiting, restores gastric motility)
+ Diphenhydramine 25 mg IV (prevents akathisia)
+ Ketorolac 15-30 mg IV (pain)
IV fluids (rehydration)

If metoclopramide is unavailable or causes akathisia:

Switch to ondansetron 4-8 mg IV (slow) + ketorolac

If oral/sublingual only:

Ondansetron ODT 8 mg (dissolves under tongue, no swallowing needed) is very practical
Follow with oral sumatriptan or ibuprofen once vomiting settles

Bottom Line

Ondansetron is a good antiemetic but is NOT the ideal choice for migraine - it stops vomiting but does nothing for the headache and may even worsen it. Metoclopramide or prochlorperazine are first-line because they treat both. However, ondansetron is a reasonable backup or adjunct, especially in the ODT form when IV access is not available, or when dopamine antagonists cause intolerable side effects.

CASE PRESENTATION

PATIENT DETAILS


Name	Miss X (identity withheld)
Age	19 years
Sex	Female
Date of Presentation	July 22, 2026

CHIEF COMPLAINT

"Severe headache with repeated vomiting and inability to eat"

HISTORY OF PRESENTING ILLNESS

Miss X, a 19-year-old female, presents with a severe unilateral headache associated with multiple episodes of vomiting and complete inability to tolerate oral intake.

The current episode began with a visual disturbance - she describes noticing a small spot in her vision that progressively expanded over several minutes until she experienced complete loss of vision lasting a few minutes. This visual symptom was followed within 60 minutes by the onset of a severe unilateral headache, which she localises as starting around the ocular/periorbital margins and radiating posteriorly to the occiput. The headache was accompanied by nausea and multiple episodes of vomiting. The vomitus was initially food material and subsequently became bilious (yellow-green), consistent with an empty stomach with bile reflux following repeated vomiting episodes. She also reports abdominal pain associated with the vomiting episodes. She has been unable to eat any food since the onset of symptoms.

HISTORY OF SIMILAR EPISODES

Approximately one week prior, the patient experienced 2 to 3 similar episodes following the same pattern:

Visual loss beginning as a small spot and expanding to complete visual loss
Followed by unilateral headache
Accompanied by nausea and vomiting

These previous episodes appear to have resolved spontaneously.

WORKING DIAGNOSIS

Migraine with Typical Visual Aura (ICHD-3: 1.2.1)

The clinical presentation satisfies the ICHD-3 diagnostic criteria for migraine with typical aura:

Criterion	Evidence in This Patient
≥2 attacks	2-3 episodes one week ago + current episode
Fully reversible visual aura	Expanding scotoma from small spot to complete visual loss
Aura develops gradually over ≥5 min	Small spot expanding progressively over minutes
Aura lasts 5-60 min	Visual loss lasting "a few minutes"
Headache follows aura within 60 min	Yes - unilateral headache follows visual loss
Unilateral headache	Yes - periorbital to occipital
Nausea and/or vomiting	Yes - multiple bilious vomiting episodes
Not better explained by another diagnosis	No fever, no neck stiffness, no focal neurology

DIFFERENTIAL DIAGNOSES

Diagnosis	Likelihood	Key Distinguishing Feature
Migraine with typical aura	Most likely	Expanding scotoma + unilateral headache + vomiting + recurrent pattern
Idiopathic Intracranial Hypertension (IIH)	Must exclude	Would show papilledema on fundoscopy; visual obscurations typically seconds only
Cerebral Venous Sinus Thrombosis (CVST)	Must exclude	Especially if on OCP; MR venography required
Posterior circulation TIA	Less likely	Abrupt, non-progressive visual loss; no headache-aura sequence
Subarachnoid Haemorrhage	Unlikely	No thunderclap onset; recurrent identical episodes
Meningitis / Encephalitis	Excluded	No fever, no neck stiffness

INVESTIGATIONS REQUESTED

Bedside / Immediate

Urine pregnancy test (mandatory before any treatment)
Blood glucose
Fundoscopy (papilledema?)

Blood Tests

Full Blood Count (FBC)
Urea, Electrolytes, Creatinine (dehydration assessment)
C-Reactive Protein / ESR (if infection suspected)

Imaging

MRI Brain (outpatient, unless red flags on examination)
MRI with MR Venography (if CVST suspected, especially if OCP use confirmed)
CT Head (only if thunderclap onset, focal signs, or if MRI unavailable urgently)

Special

Formal visual field testing (ophthalmology)
Lumbar puncture (only if imaging normal and IIH or meningitis suspected)

MANAGEMENT PLAN

Acute (In-Hospital)

Intervention	Drug/Dose	Route	Rationale
Antiemetic (1st line)	Metoclopramide 10 mg	IV slow	Treats headache + vomiting + restores gastric motility
Prevent akathisia	Diphenhydramine 25-50 mg	IV	Given with metoclopramide
Analgesia	Ketorolac 15-30 mg	IV/IM	NSAID, migraine pain relief
Rehydration	Normal Saline 500-1000 mL	IV	Dehydration from vomiting + inability to eat
Alternative antiemetic	Ondansetron 4-8 mg (ODT or IV slow)	SL/IV	If metoclopramide unavailable or causes dystonia

Prophylactic (Outpatient Follow-Up)

Given ≥3 attacks within one week, preventive therapy is indicated:

Drug	Dose	Notes
Propranolol	40-120 mg/day	First-line beta-blocker, well-tolerated
Topiramate	25-100 mg/day	First-line; counsel re: cognitive side effects
Amitriptyline	10-75 mg at night	If sleep-related triggers or comorbid anxiety
(Avoid valproate)	-	Teratogenic - avoid in woman of childbearing age

IMPORTANT CLINICAL NOTES

⚠️ OCP use must be urgently established. Migraine with aura + combined oral contraceptive pill = OR 13.9 for ischemic stroke (Bradley and Daroff's Neurology). If she is on the OCP, it must be stopped and a progestogen-only or non-hormonal alternative arranged.

⚠️ Fundoscopy is mandatory before discharge to exclude papilledema (IIH).

⚠️ Red flag safety-netting to be given: if any future episode involves thunderclap onset ("worst headache of life"), visual loss that does not recover, limb weakness, facial drooping, or slurred speech - attend emergency immediately.

⚠️ If headache is always on the same side, MRI is warranted to exclude an underlying vascular malformation.

PLAN SUMMARY

Treat acute attack with IV metoclopramide + diphenhydramine + ketorolac + IV fluids
Perform fundoscopy before discharge
Urine pregnancy test before administering triptans
Establish OCP use - counsel accordingly
Arrange outpatient neurology referral
Arrange MRI brain (outpatient)
Consider ophthalmology referral for formal visual field testing
Initiate migraine prophylaxis at outpatient review
Provide trigger diary and lifestyle advice
Safety-net patient with clear red flag symptoms
