Migraine Headache Treatment
Acute Treatment Algorithm
For mild to moderate migraine attacks, start with combination therapy of an NSAID plus acetaminophen, or the fixed-dose combination of acetaminophen/aspirin/caffeine as first-line treatment. 1
Mild to Moderate Attacks
- Begin treatment immediately upon headache onset with combination therapy of an NSAID (aspirin, ibuprofen, naproxen, or diclofenac) plus acetaminophen for optimal efficacy. 1, 2
- The fixed-dose combination of acetaminophen/aspirin/caffeine is equally effective as first-line therapy. 1
- Acetaminophen 1000 mg monotherapy can be used but is significantly less effective than NSAIDs or combination therapy. 1
- Early administration is critical—treating while pain is still mild substantially improves treatment success rates. 1, 2
Moderate to Severe Attacks
- Escalate to triptan plus NSAID combination therapy for moderate to severe attacks or when simple analgesics fail. 2, 3
- Combining a triptan with an NSAID or acetaminophen provides superior efficacy compared to either agent alone. 2, 3
- If one triptan fails, trial a different triptan as individual response varies significantly. 2
- For patients with severe nausea/vomiting, use non-oral routes: subcutaneous sumatriptan injection, intranasal formulations, or rectal suppositories. 2, 4
Refractory Cases
- For patients who fail all available triptans or have contraindications (cardiovascular disease, uncontrolled hypertension, hemiplegic migraine), escalate to CGRP antagonists (rimegepant, ubrogepant, zavegepant), dihydroergotamine, or lasmiditan. 1, 2
- Lasmiditan should only be considered after failure of all other pharmacologic treatments. 1
Emergency Department Management
- For severe migraine requiring parenteral therapy, use IV ketorolac 30 mg plus IV metoclopramide 10 mg as first-line combination therapy. 1
- IV antiemetics (metoclopramide or prochlorperazine) treat nausea while improving gastric motility and medication absorption. 2
- Consider adding dexamethasone to prevent short-term headache recurrence. 5
Critical Medication Overuse Prevention
- Limit NSAID use to ≤15 days per month to prevent medication overuse headache. 1, 2, 3
- Limit triptan use to ≤10 days per month to prevent medication overuse headache. 1, 2, 3
- Initiate preventive therapy if acute treatment is needed more than 2 days per week (≥8-10 days per month). 1, 2
- Avoid opioids and butalbital-containing analgesics entirely—these medications worsen migraine outcomes and increase medication overuse headache risk. 2
Preventive Therapy Indications
Consider preventive therapy when patients have ≥2 migraine attacks per month producing disability, contraindications to acute treatments, or frequent acute medication use. 2, 3
First-Line Preventive Medications
- Topiramate is recommended as first-choice preventive therapy due to lower cost, but requires counseling about teratogenic effects in patients of childbearing potential. 2, 3
- Propranolol or metoprolol (beta-blockers) are effective first-line options. 6
- Divalproex or valproate are effective but also require teratogenicity counseling. 6
- CGRP receptor antagonists (erenumab, fremanezumab, galcanezumab) are highly effective but limited by cost and insurance coverage. 6
Second-Line Options
- Consider ACE inhibitors, ARBs, or SSRIs if first-line treatments are not tolerated or provide inadequate response. 2
- Amitriptyline and venlafaxine are second-line due to more adverse events. 6
Chronic Migraine (≥15 Headache Days/Month)
- OnabotulinumtoxinA 155 units is FDA-approved and specifically indicated for chronic migraine, with evidence from large-scale placebo-controlled trials showing effectiveness. 2
- Rule out secondary causes before establishing chronic migraine diagnosis. 2
- Monitor closely for medication overuse headache and limit as-needed medication use. 2
Essential Lifestyle Modifications
- Counsel all patients on: adequate hydration, regular meal schedule, consistent sleep (7-8 hours nightly), regular moderate-to-intense aerobic exercise (40 minutes three times weekly), and stress management techniques. 1, 2, 3
- Regular aerobic exercise is as effective as some preventive medications. 2
- Recommend weight loss if overweight or obese, as obesity increases chronic migraine risk. 1, 3
- Encourage patients to maintain a headache diary to identify triggers, monitor treatment efficacy, and detect analgesic overuse. 2, 3
Non-Pharmacologic Therapies
- Offer cognitive-behavioral therapy, biofeedback, and relaxation training to all patients as these have good evidence for efficacy and should be part of comprehensive management. 2
Special Populations
Pregnancy and Lactation
- Acetaminophen is first-line treatment for pregnant or breastfeeding patients. 1
- NSAIDs are acceptable prior to the third trimester but must be avoided in the third trimester. 1
- Discuss adverse effects of all pharmacologic treatments during pregnancy and lactation before prescribing. 3
Pediatric Patients
- Acetaminophen, ibuprofen, intranasal sumatriptan, and intranasal zolmitriptan appear effective in children and adolescents, though data are limited. 5
- Oral eletriptan 40 mg was not effective in adolescents aged 11-17 in controlled trials. 4
Elderly Patients
- Blood pressure increases are more pronounced in elderly patients treated with triptans; monitor blood pressure closely. 4
- Pharmacokinetics are similar to younger adults, though elimination half-life may be slightly prolonged. 4
Cost Considerations
- Prescribe generic NSAIDs and older triptans (sumatriptan, naratriptan, rizatriptan) when equally effective, as these are significantly less expensive than newer agents. 1, 3
Critical Safety Warnings for Triptans
- Contraindicated in patients with: coronary artery disease, Prinzmetal's angina, uncontrolled hypertension, history of stroke or TIA, hemiplegic migraine, Wolff-Parkinson-White syndrome, or peripheral vascular disease. 4
- Discontinue immediately if chest pain, arrhythmias, or signs of vasospastic reactions occur. 4
- Monitor for serotonin syndrome when co-administering with SSRIs, SNRIs, TCAs, or MAO inhibitors. 4
- Avoid in patients taking strong CYP3A4 inhibitors due to increased eletriptan levels. 4
