II. Definitions
- Medication Overuse Headache- Headache on 15 or more days of the month with known preexisting Primary Headache AND
- Regular overuse of abortive Headache medication over 3 months- Opioids, Ergotamine and Triptans >10 days/month
- Nonopiate Analgesics (e.g. NSAIDS, Excedrin) >15 days per month
 
 
III. Epidemiology
- Accounts for 30-50% of chronic Headache patients
IV. Pathophysiology
- Excessive use of Migraine Abortive Treatment medication
- Drug dependent pattern of Headaches
- Increasing tolerance to Headache medication dosages
- Medications most prone to Rebound Headache- Occurs with all Headache medications
- Butalbital (e.g. Fiorinal): 47%
- Acetaminophen: 45%
- Opioid Analgesics: 31%
- Aspirin: 24%
- NSAIDs: 19%
- Excedrin: 18%
- Ergot alkaloids: 16%
- Triptans: 9%
- Medications containing Caffeine

V. Symptoms
- Characteristics- Variable type, severity, and location of Headache
 
- Timing- Occur in the early morning (2am - 5am) daily
 
- Palliative- Headaches resolve after Pain Medication discontinued
- Refractory to prophylactic medications
 
- Provocative factors- Headache is easily precipitated
- Withdrawal symptoms on stopping Pain Medications
 
- Associated features- Nausea and other gastrointestinal symptoms
- Asthenia
- Anxiety
- Depression
- Irritability
- Memory and concentration problems
- Neck Pain
- Vasomotor symptoms (Rhinorrhea, nasal congestion)
 
- Common presentations- Often presents to ER requesting Opioids
 
VI. Diagnosis: Medication Overuse Headache
- Questions- "Do you take a treatment for Headache attacks on more than 10 days per month?"
- "Do you do this on a regular basis?"
 
- Interpretation: Identifies Medication Overuse Headache in patient with frequent Migraine- Test Sensitivity: 95.2%
- Test Specificity: 80%
 
- References
VII. Diagnosis: Drug Use Disorder
- Drug use disorder is commonly comorbid
- Questions- "How many times in a year have used an illegal drug or used a prescription medication for non-medical use?"
 
- Interpretation: Drug Use Disorder- Test Sensitivity: 100%
- Test Specificity: 74%

VIII. Management: Preferred Protocols
- 
                          Analgesic Withdrawal- Most medications may be stopped abruptly- Non-Opioid Analgesics (e.g. nsaids)
- Triptans
 
- Gradually taper over 5 weeks (risk of withdrawal)- Opioids
- Barbiturates
- Ergot alkaloids
- Benzodiazepines
- Caffeine
 
 
- Most medications may be stopped abruptly
- Provide non-Opioid rescue medications during withdrawal- Antiemetics (Metoclopramide, Promethazine)
- Antihistamines (Diphenhydramine or Hydroxyzine)
- Most effective adjunctive withdrawal agents- Prednisone 60 mg daily for 5 days (caution, due to adverse effects)
- Migraine Prophylaxis agents- Topiramate (Topomax) 100-200 mg daily
- Amitriptyline 50 mg daily

- Initiate Headache prophylaxis simultaneously with withdrawal- Decreases Headache frequency and sustains resolution of Medication Overuse Headaches
- Beta blocker Migraine Prophylaxis was used in this study

- Other measures with limited evidence- Consider switching from Triptan to Rimegepant or Ubrogepant

IX. Management: Older Withdrawal Regimens (use with caution)
- Displayed for historical purposes and for additional strategies
- Many of the medications listed here have been replaced (e.g. fiorinal, Ergotamine)
- Withdrawal from Simple Analgesics- Protocol- Choose 1 medication from Group A and B
- Take bridge medication (Group B) on schedule
- Take rescue medication (Group A) as needed- Only use for severe Headache
- Limit to twice weekly
 
 
- Group A: Rescue - Migraine specific medications- Dihydroergotamine (DHE) or
- Long-acting Triptan (e.g. Amerge, Frova) or
- Midrin 1 PO tid for 1 week
 
- Group B: Bridge - Antiinflammatory medications- NSAIDs for 3-6 weeks on schedule- Naproxen 500 mg bid
- Nabumetone 750 mg/day
 
- Prednisone protocol- Prednisone 60 mg qd for 2 days then
- Prednisone 40 mg qd for 2 days then
- Prednisone 20 mg qd for 2 days then
- Consider Ranitidine concurrently with Prednisone- Dose: 150 mg PO bid for 6 days
 
 
- Triptan (not FDA approved)- Use bid until 48 hours Headache-free (10 day max)
 
 
- NSAIDs for 3-6 weeks on schedule
- Group C: Miscellaneous medications to consider- Start Elavil at bedtime
- Cyproheptadine (Periactin) 4 mg PO tid
 
- References
 
- Protocol
- Withdrawal from Butalbital medication (e.g. Fiorinal)- Consider Detoxification program- Indicated for more than 8 Butalbital pills per day
 
- Midrin or Periactin at doses above
- Phenergan 25-50 mg tid prn for 1 to 2 weeks
- Clonazepam 0.5-1.0 mg PO for 1 week, then taper
- Phenobarbital 30 mg PO tid for 1 week
 
- Consider Detoxification program
- Withdrawal from Ergotamine medications- Consider inpatient withdrawal- Indicated for more than 1.0 mg Ergotamine per day
 
- Naproxen (Anaprox) 500-1000 mg daily for 1-3 weeks
- Methylergonovine (Methergine) 0.2-0.4 mg tid
- Phenergan 25-50 mg tid for 1-2 weeks
 
- Consider inpatient withdrawal
- Withdrawal from Codeine containing Analgesics- Clonidine 0.1-0.2 mg tid for 1-2 weeks, then taper
- Naproxen 500-1000mg qd for 1-3 weeks
- Promethazine 25-30 mg tid prn for 1-2 weeks
 
X. Prevention
- Maximize Migraine Prophylaxis
- Limit acute Migraine Abortive Medications to 10 days per month or 2 days per week
- Long acting NSAIDs may be less likely than other simple Analgesics to cause Rebound Headaches
- Avoid butalbital (fiorinal) for Headaches
- Get control of Migraine Headaches soon after episode onset (e.g. start Triptan at higher, effective dose early)
