How is Cluster Headache Treated?

Treatment for cluster headache focuses on rapidly relieving pain during attacks and preventing future episodes. A personalized treatment plan based on the severity and frequency of attacks can help improve quality of life.

Oxygen Therapy: Breathing 100% oxygen helps relieve pain by constricting blood vessels in the brain.
Triptans: These medications help reduce headache pain by constricting blood vessels and blocking pain signals.
Calcium Channel Blockers: Medications such as verapamil are commonly used to prevent cluster headache attacks.
Steroid Injections: Corticosteroids may provide short-term relief during severe cluster periods.
Neuromodulation: Procedures such as occipital nerve stimulation or deep brain stimulation may be considered for chronic, treatment-resistant cases.
