Dosulepin (Prothiaden) for Headache Treatment

Prothiaden (dosulepin) is not recommended for headache treatment as it is not indicated for this condition and does not appear in any headache treatment guidelines. 1

Appropriate Medications for Headache Treatment

For Migraine Headaches:

  • First-line treatments for acute migraine attacks include:

    • NSAIDs such as aspirin (650-1000mg), ibuprofen (400-800mg), or naproxen sodium (275-550mg) 1
    • Triptans for moderate to severe attacks, including sumatriptan, naratriptan, and rizatriptan 1
  • For migraine prevention when indicated (≥2 attacks/month with significant disability):

    • Beta-blockers: propranolol (80-240mg/day) or timolol (20-30mg/day) have consistent evidence of efficacy 1, 2
    • Amitriptyline: 25-50mg daily (range 10-150mg) is the only antidepressant with consistent evidence for migraine prevention 3, 1
    • Anticonvulsants: divalproex sodium and sodium valproate have good evidence of efficacy 1, 2

Adjunctive Treatments:

  • Metoclopramide (10mg) or prochlorperazine (25mg) can be used to treat associated nausea and improve gastric motility during migraine attacks 1
  • Combination medications like isometheptene/acetaminophen/dichloralphenazone (Midrin) may be effective for milder migraine headaches 1

Why Dosulepin Is Not Appropriate for Headache Treatment

  • Dosulepin (Prothiaden) is a tricyclic antidepressant primarily indicated for depression, not headache 4, 5
  • The FDA label for dosulepin does not mention headache as an indication 4
  • Current migraine treatment guidelines do not include dosulepin in their recommendations 1
  • Among tricyclic antidepressants, only amitriptyline has consistent evidence supporting efficacy in migraine prevention 1, 3

Dosulepin Information (For Depression, Not Headache)

  • Standard dosing for depression: 75-150mg/day with a maximum of 300mg/day 4, 5
  • Can be administered as a single daily dose, typically at bedtime 4, 6
  • Side effects include dry mouth, drowsiness, and potential cardiovascular effects 5, 7

Clinical Recommendations for Headache Management

  • For acute migraine treatment: Use NSAIDs or triptans based on headache severity and previous response 1
  • For migraine prevention: Consider evidence-based options like propranolol, amitriptyline, or divalproex sodium 1, 3, 2
  • For tension-type headaches: NSAIDs are typically first-line treatment 1, 8
  • For mixed headache types: Amitriptyline may be particularly effective 1, 3

Important Clinical Pitfalls

  • Avoid using medications without evidence for headache treatment, as this may delay effective therapy 1
  • Be cautious about medication overuse headache when acute medications are used more than 2-3 days per week 1, 9
  • Preventive therapy should be considered when patients have ≥2 attacks per month with significant disability or use acute medications more than twice weekly 1, 9
  • Adequate trials of preventive medications require 2-3 months to assess efficacy 3, 2
