Nortriptyline for Occipital Headaches
Nortriptyline is not recommended for occipital headaches as there is no evidence supporting its efficacy, while amitriptyline has established efficacy for this condition. 1, 2
Evidence-Based Treatment Options for Occipital Headaches
First-Line Pharmacological Options
- Amitriptyline is the only tricyclic antidepressant with consistent evidence supporting its efficacy for headache prevention, with effective dosages ranging from 30-150 mg/day 1, 2
- Beta-blockers, particularly propranolol (80-240 mg/day) and timolol (20-30 mg/day), have strong evidence for efficacy in occipital headaches related to migraine 2
- Anticonvulsants such as divalproex sodium and sodium valproate have good evidence for efficacy in migraine prevention and may be useful for occipital headaches 1
Important Clinical Considerations
- Despite being in the same class as amitriptyline, nortriptyline lacks evidence for efficacy in headache prevention 1
- For patients with mixed headache types (tension-type and migraine components), amitriptyline has been shown to be superior to beta-blockers 1
- Common side effects of tricyclic antidepressants include drowsiness, weight gain, and anticholinergic symptoms 1
Procedural Interventions
- Greater occipital nerve blocks with local anesthetics and/or corticosteroids can provide both diagnostic and therapeutic benefits for occipital headaches, with relief lasting weeks to months 2, 3
- For drug-resistant cases, occipital nerve stimulation may be considered as it has shown efficacy in long-term studies 4, 5
Combination Approaches
- Combined therapy with stress management and pharmacological treatment has shown superior outcomes compared to either approach alone 6
- For patients with comorbid depression and headaches who don't respond to monotherapy, a combination of amitriptyline with an SSRI may be beneficial 7
Treatment Algorithm
- Start with amitriptyline 10-25 mg at bedtime, gradually increasing to 30-150 mg/day as tolerated 1, 2
- If ineffective or poorly tolerated, consider beta-blockers (propranolol or timolol) or anticonvulsants (divalproex sodium) 1, 2
- For patients with severe, refractory symptoms, consider occipital nerve blocks 2, 3
- For chronic drug-resistant cases, evaluate for occipital nerve stimulation 4, 5
Pitfalls and Caveats
- Medication overuse can worsen headaches; limit use of acute medications to avoid this complication 2
- Preventive treatments typically require 2-3 months to show full benefit; inadequate trial periods may lead to premature discontinuation 2
- While nortriptyline is sometimes used clinically as an alternative to amitriptyline due to its potentially better side effect profile, this practice is not supported by evidence for occipital headaches 1
