It is often difficult to treat and may significantly impair quality of life.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Report<\/jats:title>\n                    <jats:p>We report the single-blinded treatment of refractory thoracic PHN with onabotulinumtoxinA (BoNT\/A). A total of 200 IU was injected into the affected area across 40 injection points (5 IU per site), while one corner of the affected area was injected with saline as an intra-individual blinded comparator. A remaining painful area was treated with a further 100 IU BoNT\/A 24 days later.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Pain intensity decreased progressively from severe pain with attacks up to 10\/10 on the numeric rating scale (NRS) to 5\/10 in the BoNT\/A-treated area, while the saline-injected area showed no noteworthy improvement. Following the second BoNT\/A injection, the remaining painful area reduced further to a coin-sized spot. The clinical effect lasted approximately 3\u00a0months and repeated treatment stabilised substantial pain reduction for almost 1\u00a0year.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>BoNT\/A may be an effective treatment option in selected patients with refractory focal PHN, particularly when established first- and second-line treatments are ineffective, poorly tolerated or contraindicated. Further controlled studies are required to clarify efficacy, duration of benefit and repeat-treatment strategies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20494637261471112","type":"journal-article","created":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T04:14:48Z","timestamp":1784866488000},"page":"349-355","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["OnabotulinumtoxinA in refractory postherpetic neuralgia: a case report"],"prefix":"10.1177","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-8072-7569","authenticated-orcid":false,"given":"Dominic","family":"Bertram","sequence":"first","affiliation":[{"name":"Department of Neurology, TUM University Hospital Rechts der Isar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georg","family":"Haber","sequence":"additional","affiliation":[{"name":"Department of Neurology, Krankenhaus Agatharied"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dina","family":"von Rohrscheidt","sequence":"additional","affiliation":[{"name":"Department of Neurology, TUM University Hospital Rechts der Isar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas R.","family":"T\u00f6lle","sequence":"additional","affiliation":[{"name":"Department of Neurology, TUM University Hospital Rechts der Isar"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,7,23]]},"reference":[{"issue":"18","key":"e_1_3_4_2_2","first-page":"1766","article-title":"Herpes zoster","volume":"369","author":"Cohen JI","year":"2013","unstructured":"Cohen JI.
