Disclosures I have no financial disclosures to report
Off-Label Use Certain medications discussed are used off-label, without FDA approval Standard of practice If off-label, medications will be labeled as each is described
Objectives After attending this presentation, participants should be able to: Define appropriate three first-line treatments for episodic treatment of children s migraine headaches Define appropriate three first-line treatments for prophylactic treatment of children s migraine headaches Identify three key elements in the decision tree guiding the episodic, prophylactic, and/or ED management of children s migraine headaches
Migraine Diagnostic Criteria & Prevalence International Classification of Headache Criteria-3 Beta Without Aura With Aura By age 3-7 years 7-11 years 15 years prevalence 1.2%-3.2% 4%-11% 8%-23% Gender ratio boys>girls boys=girls girls>boys 50-90% of relatives also have migraine Familial hemiplegic migraine L
For a clinical problem so prevalent in children and adolescents, there is a disappointing lack of evidence from controlled, randomized, and masked trials.
Goals of Treatment Reduction of HA frequency, severity, duration, and disability Reduction of reliance on poorly tolerated, ineffective, or unwanted acute pharmacotherapies Improved QOL Avoidance of acute headache medication use (MOH) Education/promote self-management Reduction of headache-related distress and psychological symptoms
Treatment Sooner is better . School accommodations Treat immediately Have meds at school, with permission forms completed Communication
Andrew 7yo male Headaches at school- pale, nauseated Headaches happening about 1-2x/ month Ibuprofen 200mg headache is gone in 2 hours
Episodic Treatment Anti-Inflammatory effects OTCs Ketorolac Triptans Combination Products Midrin-APAP, dichloralphenazone, isometheptene Cafergot-Ergotamine and caffeine Bultalbital Antiemetics Prochlorperazine Promethazine Odansetron Lorazepam metaclopromide Treat No More Than 2x per Week

Medication Overuse Headache Description: Headache occurring on 15 or more days per month developing as a consequence of regular overuse of acute or symptomatic headache medication (on 10 or more or 15 or more days per month, depending on the medication) for more than three months. It usually, but not invariably, resolves after the overuse is stopped.
Andrew 11yo male Headaches at school- pale, nauseated Headaches happening about 6-7x/ month Rizatriptan 5mg resolves headaches within 2 hours. Missing school at least 1x/ month

Anticonvulsants Depakote (Valproate Acid) Mechanisms: ?inhibits Ca+ channels; interacts with 5-HT; reduces neurogenic inflammation in peripheral TVS SE-Drowsiness, weight gain, hair loss, pancreatitis, thrombocytopenia, associated with neural tube defects Dosing-start at 10mg/kg/day Available as ER- 1x/day dosing Disadvantages-frequent blood levels, CBC, LFT s OFF OFF- -Label Label

Acute Treatment at ED Acute Migraine Treatment in ED 0.9 % Saline bolus with: Ketorolac 0.5mg/kg (max 30 mg) IV prochlorperazine 0.15mg/kg IV (max 30mg) +/- dexamethasone +/- magnesium infusion Valproate 15-20mg/kg Dihydroergotamine (DHE) Sumitriptan 4-6mg SQ Antiemetics + DHE 0.5-1mg IV Prochlorperazine Metoclopramide 20mg IV Ketorolac 30mg-60mg IM Magnesium 1-2GM IV Valproate 300-500mg IV Corticosteroids dexamethasone 10-24mg IV) Metoclopramide 20mg IV intranasal /iv Oxytocin ? Lack of controlled trials
