Prophylaxis for Tension-Type Headache
For chronic tension-type headache prophylaxis, amitriptyline 100 mg is the first-line medication, demonstrating the strongest evidence for reducing monthly headache days by approximately 6 days compared to placebo. 1, 2
Primary Recommendation: Amitriptyline
The 2023 VA/DoD guideline explicitly recommends amitriptyline for prevention of chronic tension-type headache 1. The most recent network meta-analysis (2026) confirms amitriptyline 100 mg as the highest-ranked treatment across multiple time points (4,8, and 24 weeks), with SUCRA scores of 0.85-0.87 2. At this dose, expect:
- Reduction of 6-7 monthly headache days at 4 weeks (MD -6.59,95% CrI -11.22 to -0.64) and 8 weeks (MD -6.14,95% CrI -10.27 to -0.87) 2
- Consistent efficacy documented across multiple double-blind, placebo-controlled trials 3, 4
Important caveat: Amitriptyline 100 mg shows higher adverse event rates than placebo 2, so titrate gradually from lower starting doses (typically 10-25 mg) to minimize side effects like sedation, dry mouth, and weight gain.
Alternative Prophylactic Options
Botulinum Toxin A (BTX-A)
- BTX-A 100 U reduces monthly headache days by approximately 4 days (MD -3.79,95% CrI -7.16 to -0.33) 2
- Consider when amitriptyline is contraindicated or not tolerated
- Note: BTX-A 500 U shows higher adverse event rates 2
Other Tricyclic Antidepressants
Tricyclic antidepressants as a class are recommended for tension-type headache prophylaxis 5, 6. Beyond amitriptyline, evidence supports:
- Mirtazapine and venlafaxine have documented efficacy 4
- Weaker evidence exists for gabapentin, topiramate, and tizanidine 4
When to Initiate Prophylaxis
Start prophylactic treatment for patients with:
- Chronic tension-type headache (≥15 headache days per month)
- Very frequent episodic tension-type headache significantly impacting quality of life
- Risk of medication overuse headache from frequent acute medication use
- Inability to tolerate effective doses of acute treatment medications 3
Complementary Non-Pharmacological Interventions
The 2023 guideline recommends physical therapy or aerobic exercise for tension-type headache management 1. Evidence-based non-pharmacological options include:
- Cognitive behavioral therapy and EMG biofeedback 3, 7
- Acupuncture with documented efficacy 4
- Physical therapy targeting the cranio-cervical-mandibular region shows significant short- and medium-term effects on pain intensity and headache frequency 8
- Massage and trigger point injections 3
These should supplement, not replace, pharmacological prophylaxis in chronic cases.
Critical Pitfalls to Avoid
- Do not use migraine-specific medications (triptans, CGRP inhibitors) for tension-type headache—they are ineffective 6, 9
- Monitor for medication overuse: Patients using acute medications >10-15 days/month risk developing medication overuse headache, requiring structured withdrawal and prophylaxis 5
- Recognize the evidence quality limitation: The 2026 meta-analysis notes low to very low certainty of evidence with high heterogeneity 2, but amitriptyline remains the most consistent performer
Acute Treatment Considerations
For episodic tension-type headache, the guideline recommends:
