Case Report: Two Cases of Persistent Hiccups Complicating COVID-19.

Two cases are presented with coronavirus disease 19 (COVID-19)-related hiccups: one during initial presentation and one 10 days after COVID-19 diagnosis. Hiccups in both patients were resistant to treatment and responded only to chlorpromazine. COVID-19 patients may present with hiccups and also may have hiccups after treatment. Resistant hiccups without any underlying disease other than COVID-19 should be considered in association with COVID-19 and may respond well to chlorpromazine.
