@Naomi_D_Harvey @Ilikebirbs1 There’s a larger study here based on South Korean health records but because the patients were on so many other drugs (some of which may affect the QT interval) it’s hard to tell what’s what.

@keer_31 I think it’s rather rare. There are a few case reports in the literature and this paper ⬇️ but most of the patients were on multiple drugs, so probably including QT-prolonging ones. I’d say do an ECG if you’re worried about it.

@atomicaceso Very rarely. Here’s an analysis from nationwide electronic health records in South Korea. https://t.co/9ox70mbWPh

#OTILT Famotidine can cause QT prolongation, especially in people with electrolyte abnormalities, but it is not clear if it is through HERG channel inhibition. Switch to ranitidine instead! @BWDionne @balsamo_briana @CodyL44740165 https://t.co/oTNW9PCGbg
