She was diagnosed with herpes zoster, treated with valacyclovir and gabapentin, and made a full recovery. Ensuring patients are protected against varicella-zoster virus before starting diroximel fumarate can prevent this painful infection. Thus, we recommend vaccination against the varicella-zoster virus prior to diroximel fumarate initiation be incorporated as the standard of care.<\/jats:p>","DOI":"10.1136\/bcr-2024-264081","type":"journal-article","created":{"date-parts":[[2025,4,3]],"date-time":"2025-04-03T02:28:23Z","timestamp":1743647303000},"page":"e264081","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Herpes zoster infection in a patient with relapsing-remitting multiple sclerosis treated with diroximel fumarate"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7465-5749","authenticated-orcid":false,"given":"John","family":"Dempsey","sequence":"first","affiliation":[{"name":"SUNY Upstate Medical University Norton College of Medicine, Syracuse, New York, USA"},{"name":"Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Balshi","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Sloane","sequence":"additional","affiliation":[{"name":"Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,4,2]]},"reference":[{"unstructured":"Biogen IDEC, Inc .
