Data regarding the cardiovascular effects of maternal antihistamine use during pregnancy remain limited. We report a near\u2010term fetus with sustained SVT temporally associated with maternal ingestion of cetirizine and an antihistamine\u2013decongestant combination for the treatment of allergic rhinitis. Owing to the persistence of the tachyarrhythmia during hospitalization, transplacental antiarrhythmic therapy with flecainide was initiated. After 48\u2009h of treatment, successful rhythm control was achieved. Concurrent use of cetirizine and an antihistamine decongestant in a single dose during pregnancy resulted in sustained SVT in the fetus, necessitating treatment. Therefore, the use of cetirizine in the third trimester and antihistamine decongestants throughout pregnancy requires further investigation.<\/jats:p>","DOI":"10.1155\/crog\/6498180","type":"journal-article","created":{"date-parts":[[2026,5,4]],"date-time":"2026-05-04T16:00:27Z","timestamp":1777910427000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unexpected Fetal Supraventricular Tachycardia Temporally Associated With Maternal Antihistamine Use: A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1932-4331","authenticated-orcid":false,"given":"Khadijeh Riazi","family":"Kermani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1157-9700","authenticated-orcid":false,"given":"Shahrokh","family":"Rajaei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5963-1331","authenticated-orcid":false,"given":"Razieh Moazami","family":"Goudarzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3345-0345","authenticated-orcid":false,"given":"Nazanin","family":"Abdi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,5,4]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10112510"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/jce.14406"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2017-016597"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.28947"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0119551"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13052-018-0570-1"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.4103\/0976-500X.95503"},{"key":"e_1_2_12_8_2","doi-asserted-by":"crossref","first-page":"487","DOI":"10.1002\/9781119959946.ch28","volume-title":"Pharmacoepidemiology","author":"Mitchell A.
