Brief Summary

There is no doubt that chronic migraine is a large public health problem, which is both disabling and costly. Many patients and headache doctors see Botulinum toxin (Botox) treatment as a big stride forward, but it is a problem that the effect has been shown in only one study, with a low therapeutic gain. For this reason, before this costly treatment is expanded to potentially several thousand patients in Norway, it would be highly desirable that 1) there is additional good scientific evidence for use of Botox , 2) a more effective treatment procedure is developed, 3) the potential for unblinding is reduced, and 4) the dose, number of injection sites and cost can be halved, and 5) the adverse effects are minimized. These may be the results of this pilot project where injections are given along the sutures, which can open up for a later randomized, blinded and controlled study.

Outcome Measures

Primary Outcomes (1)

  • Number of Adverse Events

    adverse events (other than clearly related to migraine) will be recorded in the diary by the patients and reviewed during the scheduled visits

    12 weeks

Secondary Outcomes (1)

  • Injection Time

    Week 1

Study Arms (1)

BoNT-A injected

EXPERIMENTAL

BoNT-A (Botulinum toxin A) injected in the head on specific sites and in half the usual concentration

Drug: BoNT-A

Interventions

BoNT-ADRUG

90U BoNT-A, given in one treatment as 18 injections of 5u (0.2 ml) each, on specific preselected sites along the sutures of the skull. First 100 U of Botox® is solved in 4 ml (cc) of isotone saline water (9 mg/ml), distributed in 4 syringes. This is half the usual concentration, allowing for better diffusion in order to reach the target structures.

Also known as: Botox, Botulinum Toxin Type A
BoNT-A injected

Eligibility Criteria

Age18 Years - 64 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:
