How should I manage a typical tension-type headache, including red-flag assessment, acute treatment, and preventive options?

Management of Tension-Type Headache

Red Flag Assessment

First, exclude secondary causes by screening for specific warning signs that mandate urgent evaluation or neuroimaging:

• New headache onset after age 50, abnormal neurological examination findings, progressive worsening pattern, headaches that worsen with Valsalva maneuver, headaches that awaken the patient from sleep, fever or signs of infection 1, 2
• Any atypical features not meeting strict tension-type headache criteria warrant further investigation 1

Acute Treatment

For episodic tension-type headache, initiate treatment with ibuprofen 400 mg or acetaminophen 1000 mg at headache onset as first-line therapy. 1

• These agents provide statistically significant pain-free response at 2 hours in episodic tension-type headache 1
• Acetaminophen doses between 500-650 mg are inadequate and should be avoided 1
• Simple analgesics and NSAIDs are the mainstay of acute treatment for episodic tension-type headache 3
• Combination analgesics containing caffeine (aspirin, acetaminophen, and caffeine) can be used as second-line alternatives 1, 3

Critical pitfall: Avoid frequent and excessive use of analgesics—do not use acute medications more than 2 days per week to prevent medication-overuse headache 1, 3

Medications to Avoid

• Triptans, muscle relaxants, and opioids should not be used for tension-type headache 3

Preventive Therapy

Preventive therapy is indicated when the patient requires acute treatment more than 2 days per week or has chronic tension-type headache (≥15 days per month). 1

First-Line Preventive Treatment

Amitriptyline 50-100 mg daily is the only drug with consistent high-quality evidence for reducing monthly headache days in chronic tension-type headache. 1, 3

• Start at a low dose (10-25 mg at bedtime) and titrate upward based on response and tolerability 1
• Efficacy has been documented in multiple double-blind, placebo-controlled studies 4, 3
• Common adverse effects include drowsiness, weight gain, dry mouth, constipation, and urinary retention—particularly problematic in older adults and patients with cardiac comorbidities 1
• Overdose potential requires monitoring 1

Second-Line Preventive Options

• Mirtazapine or venlafaxine if amitriptyline is ineffective, poorly tolerated, or contraindicated 1, 5, 3
• Weaker evidence exists for gabapentin, topiramate, and tizanidine 4

Therapies NOT Recommended

OnabotulinumtoxinA is not recommended for chronic tension-type headache—pooled data from 12 randomized controlled trials showed no statistically significant improvement. 1

Non-Pharmacological Interventions

Consider the following as adjuncts to pharmacological therapy, though evidence quality varies:

• EMG biofeedback has documented effectiveness in tension-type headache 3
• Cognitive-behavioral therapy and relaxation training are most likely effective 3, 6
• Acupuncture may be valuable for patients with frequent tension-type headache, though evidence is limited 4, 3
• Physical therapy may be an option, but robust scientific evidence is lacking 3

Note: The 2023 VA/DoD guidelines found insufficient evidence to recommend for or against isolated use of biofeedback, cognitive-behavioral therapy, mindfulness-based therapies, or progressive muscle relaxation 1

Treatment Algorithm

1. Episodic tension-type headache (<15 days/month):

   • Acute treatment only: Ibuprofen 400 mg or acetaminophen 1000 mg at onset 1
   • Monitor frequency of use—if exceeding 2 days/week, initiate preventive therapy 1

2. Frequent episodic or chronic tension-type headache (≥15 days/month):

   • Initiate amitriptyline 10-25 mg at bedtime, titrate to 50-100 mg daily 1, 3
   • Continue acute treatment with simple analgesics as needed (≤2 days/week) 1
   • If amitriptyline fails or is contraindicated, switch to mirtazapine or venlafaxine 1, 3

3. Refractory cases:

   • Consider adding non-pharmacological interventions (EMG biofeedback, cognitive-behavioral therapy) 3, 6
   • Reassess for medication-overuse headache 3
