Management of Headache in Subarachnoid Hemorrhage

Initial Assessment and Management

Headache is a predominant symptom in SAH, described as "the worst headache of my life" by 80% of patients who can give a history, according to the American Heart Association 1, 2
Rapid assessment of headache severity should be performed using validated pain scales, as headache intensity correlates with clinical severity and potential outcomes, as recommended by the American Stroke Association 3
Blood pressure control is essential not only for preventing rebleeding but also for managing headache - systolic blood pressure should be maintained below 160 mmHg using titratable agents like nicardipine, labetalol, or clevidipine, as suggested by the American College of Cardiology 4, 5

Oral acetaminophen should be administered to all patients with SAH-associated headache as the foundation of pain management, according to the American College of Emergency Physicians 5

Nimodipine (60 mg every 4 hours for 21 days) should be administered to all SAH patients - while primarily used to improve neurological outcomes, it may have secondary benefits for headache management, as recommended by the American Academy of Neurology 3, 5
Antiseizure medications may provide dual benefits for seizure prophylaxis and headache management in select patients, according to the American Epilepsy Society 5

Avoid hypervolemia when managing blood pressure, as this can increase complications without improving outcomes, as warned by the American College of Cardiology 5

Consider headache specialist referral for patients with persistent post-SAH headache, as recommended by the American Headache Society 5

Headache occurs in 74% of confirmed Subarachnoid Hemorrhage cases and is described as "the worst headache of my life" by 80% of patients who can provide history, with associated symptoms including nausea/vomiting, nuchal rigidity, and photophobia 6

Avoid routine long-term opioid management, as the actual efficacy of opioids for SAH headache is disappointingly poor, with a median pain reduction after opioid administration of only -1 point on the numeric rating scale 7

The American Academy of Neurology recommends avoiding medication overuse headache by counseling patients early about the risks of using simple analgesics on more than 15 days per month or opioids on greater than 10 days per month for more than 3 months, as supported by the Journal of Neurology, Neurosurgery and Psychiatry 8
