Preventive treatments for patients experiencing frequent cluster headache episodes include:

  • Offer prophylactic treatment such as verapamil during a bout of cluster headache, with specialist advice before starting, including ECG monitoring for cardiac adverse effects .
  • Consider other prophylactic options like topiramate or propranolol after a full discussion of benefits and risks, especially if verapamil is unsuitable or ineffective .
  • In cases where first-line prophylaxis is ineffective or contraindicated, consider a course of up to 10 sessions of acupuncture according to patient preference and risk profile .

Methods for monitoring preventative treatment include:

  • Regular review to assess symptom response to treatment and monitor for adverse effects .
  • Seek specialist advice or referral if symptoms persist despite optimal management, or if there are atypical or refractory symptoms .
  • For verapamil, ECG monitoring is recommended before and during treatment to check for cardiac adverse effects .
