Correct answer: C — Use oxygen or subcutaneous triptan plus verapamil prevention
The best answer is “Use oxygen or subcutaneous triptan plus verapamil prevention”. This is cluster headache. Rapid-onset oxygen or subcutaneous triptan treats attacks, while preventive therapy is started during the bout. Oral analgesics are too slow, opioids add harm and indomethacin responsiveness characterizes different trigeminal autonomic cephalalgias.
