Usually two acupuncture sessions are performed per week, in series of 10 to 15 treatments usually followed by a break of 2 - 3 weeks. Depending on the development of the therapy, further treatment series may be necessary. 3 - 4 months after the final treatment, two to four refresher acupuncture sessions are recommended to help stabilize the success of the therapy. If the disease appears again after months or years, e.g. in the case of migraines, it is helpful to start another acupuncture series in time. This series is usually much shorter than the first.
