Migraine Treatment with Sumatriptan

Introduction to Sumatriptan Use

• The American Academy of Neurology recommends sumatriptan as second-line therapy for moderate to severe migraine attacks when over-the-counter NSAIDs provide inadequate relief 1, 2

Stepped Care Algorithm for Migraine Treatment

• The American College of Physicians suggests beginning with NSAIDs (aspirin, ibuprofen, or diclofenac potassium) for all migraine attacks, reserving paracetamol for patients intolerant of NSAIDs 1, 2
• Offer sumatriptan when over-the-counter analgesics provide inadequate headache relief after 2-3 migraine episodes, or when migraine attacks are moderate to severe in intensity 1, 2, 3

Optimal Timing and Route of Administration

• Take sumatriptan early in the attack when headache is still mild for maximum effectiveness, and do not use during the aura phase 1, 2
• Use oral sumatriptan for typical migraine attacks without severe nausea or vomiting, with dosing of 50-100 mg at onset 2, 3
• Use subcutaneous sumatriptan 6 mg when all oral triptans have failed, patient rapidly reaches peak headache intensity, or severe vomiting prevents oral medication 1, 2, 4

Critical Contraindications

• The American Heart Association advises against using sumatriptan in patients with ischemic heart disease or coronary vasospasm, previous myocardial infarction, uncontrolled hypertension, basilar or hemiplegic migraine, or concurrent use with ergotamines or MAO inhibitors 1, 3, 5

Managing Treatment Failure

• If one triptan fails, try a different triptan, as failure of one does not predict failure of others, and allow an adequate trial period of at least 3 consecutive attacks before abandoning 1, 2
• For headache recurrence, combine sumatriptan with fast-acting NSAIDs to prevent relapse, but be aware that repeating treatment increases the risk of medication-overuse headache 1, 2

Preventing Medication-Overuse Headache

• Limit sumatriptan use to no more than 2 days per week, as using acute medications more than twice weekly can lead to daily headaches, and consider initiating preventive therapy if treatment is needed more frequently 1, 4, 6

Special Populations

• For patients with significant nausea, add metoclopramide 10 mg or domperidone to sumatriptan, as antiemetics provide synergistic analgesia beyond treating nausea alone 1, 4
