Treatment of Post-Concussion Headache
For acute post-concussion headache, use ibuprofen 400-800 mg every 6 hours as first-line treatment, with acetaminophen 1000 mg as an alternative for patients who cannot tolerate NSAIDs. 1
Initial Pharmacologic Management
First-Line Options
- Ibuprofen is the preferred first-line agent at doses of 400-800 mg every 6 hours due to its effectiveness in reducing both pain and inflammation associated with post-concussion headache 1
- Naproxen sodium 275-550 mg every 2-6 hours offers a longer duration of action and represents an equally effective NSAID alternative 1
- Acetaminophen 1000 mg should be reserved for patients with NSAID contraindications (renal impairment, GI bleeding history, aspirin sensitivity), though it is generally less effective when used alone 2, 1
Combination Therapy for Migraine-Type Features
- When post-concussion headache exhibits migraine characteristics (throbbing quality, photophobia, phonophobia, nausea), use aspirin-acetaminophen-caffeine combination therapy rather than single-agent treatment 1
- This combination provides synergistic analgesia and is strongly recommended for migraine-like presentations 3, 1
Critical Timing and Administration Principles
- Begin treatment early in the headache phase for maximum effectiveness—waiting until pain becomes severe reduces medication efficacy 1
- Limit acute medication use to no more than twice weekly to prevent medication overuse headache, which can develop with frequent analgesic use and lead to daily refractory headaches 2, 1
Management of Associated Symptoms
Nausea and Vomiting
- When nausea accompanies post-concussion headache, add metoclopramide 10 mg or prochlorperazine as adjunctive therapy 1
- These antiemetics provide both symptom relief and synergistic analgesia through central dopamine receptor antagonism 3
- For children specifically, nonopioid analgesia (ibuprofen or acetaminophen) should be offered with counseling about analgesic overuse risks 2
Pediatric-Specific Considerations
- Avoid aspirin in children and adolescents due to Reye's syndrome risk 1
- For children with severe or worsening headache after concussion, clinical observation and consideration of head CT is warranted to evaluate for intracranial complications 2
- Children with acutely worsening symptoms during observation should undergo emergent neuroimaging 2
Medications to Avoid
- Never use opioids for post-concussion headache as they lead to dependency, rebound headaches, and loss of efficacy without providing superior pain relief 2, 1
- Avoid barbiturate-containing compounds for the same reasons 1
- Do not administer 3% hypertonic saline outside research settings, as evidence does not support its use for acute post-concussion headache 2
When Initial Treatment Fails
Escalation Strategy
- If NSAIDs fail after 2-3 headache episodes, consider whether the headache phenotype is migraine-type and escalate to triptan therapy (sumatriptan, rizatriptan) for moderate-to-severe attacks 3
- For refractory cases, dihydroergotamine (DHE) represents an alternative option 3
Chronic Post-Concussion Headache (>1 month)
- Refer for multidisciplinary evaluation when headaches persist beyond one month, as chronic post-concussion headache is multifactorial and requires comprehensive assessment 2
- Consider analgesic overuse as a contributory factor in persistent cases 2
- Evaluate for comorbid conditions including depression, anxiety, insomnia, and vestibular dysfunction that commonly accompany chronic post-concussion symptoms 4
Non-Pharmacologic Adjuncts
- Physical therapy is recommended for management of post-concussion headache, particularly when cervicogenic features are present 2
- Graded aerobic exercise should be offered in addition to pharmacologic treatment, with gradual increases in intensity performed at least once weekly for 4 weeks 2
- For persistent vestibular dysfunction, vestibular rehabilitation including habituation exercises and balance training should be initiated 2
Common Pitfalls to Avoid
- Do not use acetaminophen alone as first-line therapy—it is significantly less effective than NSAIDs for post-concussion headache 1
- Do not allow patients to escalate medication frequency in response to persistent symptoms, as this creates medication overuse headache; instead transition to preventive strategies 3
- Do not dismiss early symptoms—high early symptom burden (particularly headache and fatigue) is a risk factor for developing chronic post-concussion syndrome 4
- Do not prescribe opioids even for severe pain, as they worsen long-term outcomes and create dependency without providing superior analgesia compared to NSAIDs and combination therapy 2, 1
