What is the treatment for abdominal migraine?

Treatment of Abdominal Migraine

For abdominal migraine, first-line treatment should include NSAIDs such as ibuprofen or naproxen, followed by triptans if NSAIDs fail, with propranolol or cyproheptadine recommended for prophylaxis in recurrent cases. 1

Acute Treatment

Abdominal migraine presents with paroxysmal, recurrent abdominal pain attacks often accompanied by pallor, nausea, vomiting, anorexia, and sometimes headache and photophobia. The treatment approach follows similar principles to those for typical migraine headaches:

First-Line Therapy:

• NSAIDs:
  • Ibuprofen: 400-600mg
  • Naproxen sodium: 500-550mg 1
  • These medications should be used at adequate doses for optimal effect

Second-Line Therapy:

• Triptans (if NSAIDs provide inadequate relief):
  • Sumatriptan: 50mg orally (for adolescents and adults) 1, 2
  • Rizatriptan: 10mg orally (for adolescents weighing ≥40kg) 1

Combination Therapy:

• The American College of Physicians recommends combination therapy of a triptan and an NSAID for patients with inadequate response to monotherapy 3
• Sumatriptan plus naproxen has shown superior efficacy compared to either medication alone 4

For Accompanying Symptoms:

• Antiemetics should be considered even if vomiting is not present, as nausea itself can be disabling 1

Prophylactic Treatment

For patients with frequent or severe abdominal migraine attacks, prophylactic treatment should be considered:

First-Line Prophylaxis:

• Propranolol: Has shown excellent response in 75% of pediatric patients with abdominal migraine 5
  • FDA-approved for migraine prophylaxis 6
  • Dosage should be individualized based on patient response

Alternative Prophylactic Options:

• Cyproheptadine: Effective in pediatric patients, with 33% showing excellent response and 50% showing fair response 5
• Topiramate: Has shown efficacy in adult cases of abdominal migraine 7, 1

Important Clinical Considerations

1. Early Treatment:

   • Treating early in an attack, when pain is still mild, provides better outcomes than waiting until pain is moderate or severe 4

2. Medication Limitations:

   • Limit triptan use to no more than 9 days per month to prevent medication overuse headache 1
   • NSAIDs should not be used for more than 15 days per month 1

3. Duration of Prophylactic Treatment:

   • Typically continued for at least 6 months, though some patients may require longer treatment (10 months to 3 years) 5

4. Monitoring:

   • Track frequency, severity, duration, and response to treatment using a headache/pain diary 1
   • Identify and avoid potential triggers (certain foods, stress, fatigue) 1

Special Considerations

• Diagnosis: Abdominal migraine is a clinical diagnosis based on recurrent stereotypic episodes of paroxysmal abdominal pain with wellness between episodes 8
• Underdiagnosis: Abdominal migraine is likely underdiagnosed, especially in adults 7
• Family History: A positive family history of migraine is common in patients with abdominal migraine 5, 7

Treatment Algorithm

1. Initial Approach: Start with NSAIDs at appropriate doses
2. If Inadequate Response: Add or switch to a triptan
3. For Frequent Attacks: Consider prophylactic therapy with propranolol or cyproheptadine
4. For Refractory Cases: Consider topiramate or combination therapies

By following this evidence-based approach to treating abdominal migraine, clinicians can help improve outcomes and quality of life for affected patients.
