The Goal of Migraine Prevention
If you have frequent migraine attacks, you should learn about the benefits of preventive therapy. Today, the best preventive medications can reduce the frequency of migraine attacks by 50 to 80 percent. For the majority of patients, cutting the number of attacks in half is a realistic goal. However, this means that even if treatment is "successful," you may still have to use acute treatments (medications that treat migraine attacks once they occur) occasionally.
Another major benefit of taking preventive medications for migraine is that they can reduce the intensity and length of migraine attacks when they do ultimately occur. For many sufferers, even a small improvement can make the difference between being disabled by the migraine and being able to function normally.
