How should a tension-type headache in an adult be managed?

Management of Tension-Type Headache in Adults

For acute tension-type headache, use ibuprofen 400 mg or acetaminophen 1000 mg as first-line treatment; for chronic tension-type headache prevention, use amitriptyline 50-100 mg daily. 1

Acute Treatment

First-Line Pharmacotherapy

• Ibuprofen 400 mg is recommended for acute tension-type headache, demonstrating statistically significant pain-free response at 2 hours 1, 2
• Acetaminophen 1000 mg is equally effective as ibuprofen for acute episodes 1, 2
• Lower doses of acetaminophen (500-650 mg) do NOT show statistically significant improvement and should be avoided 1

Comparative Efficacy

Network meta-analysis shows the ranking for 2-hour pain-free rates: ibuprofen > diclofenac-K > ketoprofen > acetaminophen > naproxen > placebo 2. Ibuprofen achieved a risk ratio of 2.86 compared to placebo, while diclofenac-K showed 2.61 2. Both ibuprofen and diclofenac-K represent high-quality evidence options 2.

Critical Pitfall: Medication-Overuse Headache

Avoid frequent and excessive use of analgesics to prevent medication-overuse headache, which can transform episodic tension-type headache into chronic daily headache 3. Triptans, muscle relaxants, and opioids should NOT be used for tension-type headache 3.

Preventive Treatment for Chronic Tension-Type Headache

First-Line Pharmacotherapy

• Amitriptyline 50-100 mg daily is the drug of first choice for chronic tension-type headache prevention 1, 4
• Both 50 mg and 100 mg doses significantly reduce monthly headache days 1
• Amitriptyline 100 mg ranked highest (SUCRA 0.85-0.87) at 4,8, and 24 weeks for reducing monthly headache days 4
• At 8 weeks, amitriptyline 100 mg reduced monthly headache days by 6.14 days compared to placebo 4

Important Safety Considerations

Be aware of anticholinergic adverse effects, especially in older patients and those with cardiac comorbidities 1. Monitor for potential overdose risk 1. Amitriptyline 100 mg shows higher adverse event rates than placebo 4.

Second-Line Options

• Mirtazapine and venlafaxine are second-choice preventive medications 3
• OnabotulinumtoxinA is NOT recommended for chronic tension-type headache—it showed no statistically significant improvement in critical outcomes across 12 randomized controlled trials 1

Non-Pharmacologic Interventions

Physical Therapy and Exercise

• Physical therapy targeting the cranio-cervical-mandibular region significantly decreases pain intensity and headache frequency in short and medium term 5
• Aerobic exercise can be used in tension-type headache management 1

Behavioral Interventions

• EMG biofeedback has documented effectiveness for tension-type headache 3
• Cognitive-behavioral therapy and relaxation training are most likely effective 3
• Acupuncture may be valuable but lacks robust scientific evidence for superiority over other treatments 6, 3

Manual Therapy

Manual therapy significantly decreases headache intensity and has efficacy equal to prophylactic medication and tricyclic antidepressants 6. However, standardized protocols are lacking 5.

Treatment Algorithm

For episodic tension-type headache:

1. Start with ibuprofen 400 mg or acetaminophen 1000 mg for acute episodes 1
2. Add non-pharmacologic interventions (physical therapy, EMG biofeedback) 5, 3
3. Educate about trigger factor identification and medication-overuse prevention 3

For chronic tension-type headache (≥15 days/month):

1. Initiate amitriptyline 50-100 mg daily for prevention 1
2. Continue acute treatment with ibuprofen 400 mg or acetaminophen 1000 mg as needed 1
3. Incorporate physical therapy targeting cranio-cervical-mandibular region 5
4. Consider EMG biofeedback and cognitive-behavioral therapy 3
5. If amitriptyline fails or is not tolerated, consider mirtazapine or venlafaxine 3
