The U.S. Food and Drug Administration, 2010 and Läkemedelsverket in Sweden, 2011, approved one of botulinum toxin drugs for injection to prevent headaches in adult patients with chronic migraine.
Chronic migraine is defined as having a history of migraine and experiencing a headache on most days of the month.

To treat chronic migraines, botulinum toxin is given approximately every 12 weeks as multiple injections in the forehead (very similar to that given in cosmetic treatment of forehead’s wrinkles), around the head and neck to try to dull future headache symptoms. Such a treatment takes less then 5-10 minutes to complete.

Botulinum toxin has successfully been used off-label to treat also other forms of headaches.
The vast majority of the patients experience symptom’s relief 1 to 2 weeks after the treatment. Usually, the frequency of headaches drastically decreases or the headaches themselves cease completely. If the headaches occur after all during the treatment period, they are usually much less intense and have essentially shorter duration.

Depending on headache’s type, from 80% to over 90% of patients can be helped by this treatment.

Dr Jacek Bartosik has been treated patients with various headache problems since year 2000. He has until now executed more the 3000 procedures of that kind.
