Cluster headache — Clinical Guidelines

Overview

Cluster headache is a primary headache disorder characterized by severe unilateral pain, often around the eye, accompanied by autonomic symptoms, and typically occurring in clusters over periods of weeks or months. 1 2 8

Diagnosis

Key Criteria: Severe unilateral orbital/temporal pain, ipsilateral cranial autonomic features (ptosis, miosis, conjunctival injection), and episodic nature. 1 3 8

Recommended Tests: No extensive diagnostic evaluations are typically indicated; clinical criteria suffice. Imaging may be considered if secondary causes are suspected. 5 9

Validation Tools: The Erwin Test for Cluster Headache can aid in screening and validation of cluster headache diagnosis. 3

Management

Acute Treatment:

- Oxygen: 100% oxygen at ≥12 L/min for 15 minutes. - Sumatriptan: 6 mg subcutaneous sumatriptan. 2

Prophylaxis:

- Verapamil: Daily dose of at least 240 mg (adjusted for efficacy and tolerability). - Corticosteroids: At least 100 mg dose to achieve therapeutic effect. 2

Alternative Treatments: Acupuncture may be considered in refractory cases, though evidence is limited. 7

Special Populations

Comorbidities: Hyperlipidemia may be associated with some cases of cluster headache, warranting lipid profile assessment in certain patients. 6

Secondary Causes: Consider imaging for vascular malformations or other structural abnormalities if clinical suspicion arises. 10

Key Recommendations

Use 100% oxygen at ≥12 L/min for 15 minutes or 6 mg subcutaneous sumatriptan for acute cluster headache attacks. (Evidence: Strong 2)

Initiate verapamil prophylaxis at a daily dose of at least 240 mg for cluster headache prevention. (Evidence: Strong 2)

Evaluate for potential secondary causes such as vascular malformations or infections with appropriate imaging if clinical suspicion exists. (Evidence: Moderate 5 10)
