However, it remains a potential drug of abuse due to its low price, availability and ability to modulate GABA-A. Others have reported presentations that challenge the GABAergic mechanism of carisoprodol. Here, we present a case of serotonin syndrome with carisoprodol holding a pivotal role. This case highlights the potential serotonergic activity of carisoprodol which contradicts the agent\u2019s supposed GABAergic mechanism of action.<\/jats:p>","DOI":"10.1136\/bcr-2025-269513","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T06:05:23Z","timestamp":1765173923000},"page":"e269513","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Carisoprodol poisoning with serotonin toxicity"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2746-4029","authenticated-orcid":false,"given":"Conor Salmaan","family":"O\u2019Flynn","sequence":"first","affiliation":[{"name":"Emergency Department, The Alfred, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shrey","family":"Singh","sequence":"additional","affiliation":[{"name":"Emergency Department, The Alfred, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gim","family":"Tan","sequence":"additional","affiliation":[{"name":"Emergency Department, The Alfred, Melbourne, Victoria, Australia"},{"name":"School of Public Health and Preventative Medicine, Monash University, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,12,7]]},"reference":[{"key":"2026010204251110000_18.12.e269513.1","unstructured":"World Health Organization .
