What are the recommended acute and preventive migraine medications, with appropriate dosing, for children (including age and weight considerations and contraindications)?

Migraine Medications for Children

For acute treatment in children and adolescents, use ibuprofen (7.5-10 mg/kg) as first-line therapy; for moderate-to-severe attacks or inadequate response, use triptans in adolescents—specifically sumatriptan/naproxen combination, zolmitriptan nasal spray, sumatriptan nasal spray, rizatriptan ODT, or almotriptan oral. 1

Acute Treatment

First-Line Therapy

• Ibuprofen 7.5-10 mg/kg is the primary acute treatment for all severity levels of migraine in children and adolescents 1, 2
• Acetaminophen 15 mg/kg is an alternative option, though ibuprofen is preferred 2, 3
• Treat early in the attack for optimal efficacy 1

Second-Line Therapy (Adolescents)

When over-the-counter medications fail or for moderate-to-severe headaches, the following triptans are recommended 1:

• Sumatriptan/naproxen combination (oral) 1
• Zolmitriptan nasal spray (5 mg or 20 mg) 1, 3
• Sumatriptan nasal spray 1, 3
• Rizatriptan ODT 1, 4
• Almotriptan oral 1

Important Acute Treatment Considerations

• If one triptan fails, try a different triptan or an NSAID-triptan combination 1
• For rapidly spiking headache pain, use non-oral triptan formulations 1
• For prominent nausea/vomiting, use non-oral triptans or add an antiemetic 1
• Avoid acute medication overuse, which can lead to medication overuse headache 1

Preventive Treatment

When to Consider Prevention

Preventive treatment is appropriate for children/adolescents with 1:

• Frequent migraine attacks
• Disabling headaches affecting quality of life or school performance
• Medication overuse headache

Critical Counseling Point

Discuss with families that placebo was as effective as active medication in many pediatric preventive trials, so the decision to use preventive medication should be carefully considered 1

Evidence-Based Preventive Options

Strongest Evidence:

• Amitriptyline combined with cognitive behavioral therapy 1
• Topiramate 1, 2
• Propranolol 1

These three medications have the best supporting evidence, though all showed high placebo response rates in trials 1

Additional Options (depending on patient profile):

• Flunarizine 5 mg/day is likely effective and well-tolerated 3, 5
• Cyproheptadine should be reserved for younger children unable to swallow tablets 2, 4
• Divalproex sodium is a considerable option based on comorbid profile 2

Age-Specific Considerations for Prevention

• Younger children (unable to swallow tablets): Cyproheptadine 2, 4
• Older children/adolescents: Amitriptyline preferred due to once-daily dosing and minimal side effects 2
• Adolescents with specific comorbidities: Topiramate or divalproex based on individual profile 2

Critical Safety Warnings for Preventive Medications

• Topiramate and valproate are teratogenic 1
• Counsel adolescent females on effective birth control methods 1
• Advise folate supplementation when using these medications 1

Common Pitfalls to Avoid

• Do not delay acute treatment—early intervention is more effective 1
• Do not continue the same triptan if ineffective; switch to a different triptan or add an NSAID 1
• Do not overlook lifestyle modifications and trigger identification, which are fundamental to long-term management 1, 3
• Do not prescribe preventive medications without discussing the high placebo response rates in pediatric trials 1
