Measure
Preventive Drugs From the Start
Use of preventive drugs from the start without abrupt withdrawal. This group was not explicitly advised to withdraw overused medication. Preventive medication was started on day 1, based on a priority list of medicines (Betablockers, candesartan, topiramate, amitriptyline or other preventive relevant drugs. For each patient preventive agent was chosen on the basis of a list of specifications considering the primary headache, side-effects of the drug and what they have tried before.

Population: Headache diary information available

Change in Headache days per month

Outcome measures

Outcome measures
Measure
Prophylaxis From the Start
n=17 Participants
Use of preventive drugs from the start without abrupt withdrawal Betablockers or other preventive drugs based on primary headache type: Several preventive drugs based on each individual regarding type of original headache type (i.e angiotensin II blockers, betablockers, valproate, tricyclic antidepressants or gabapentin)
Abrupt Withdrawal
n=18 Participants
Device: Abrupt withdrawal. Standard out-patients detoxication program including telephone call after 2 weeks and rescue medicine up to 2 days/week Betablockers or other preventive drugs based on primary headache type: Several preventive drugs based on each individual regarding type of original headache type (i.e angiotensin II blockers, betablockers, valproate, tricyclic antidepressants or gabapentin)
Controls
n=18 Participants
Active control: No instruction for abrupt withdrawal or prophylactic treatment. The controls finished the study period after 5 months observation, and were then offered the optimal type of treatment Betablockers or other preventive drugs based on primary headache type: Several preventive drugs based on each individual regarding type of original headache type (i.e angiotensin II blockers, betablockers, valproate, tricyclic antidepressants or gabapentin)
Headache Days
7.2 days/month
Interval 2.7 to 11.8
4.2 days/month
Interval 3.3 to 7.4
1.6 days/month
Interval 0.1 to 1.8

SECONDARY outcome

Timeframe: 5-month follow-up

Population: Headache diary information available

Headache index (HI) per month calculated by the sum of products of headache days /month combined with mean daily hours with headache and mean daily headache severity on days with headache. High HI reflect high headache burden
