I had been on Corlanor after a cardiac arrest/shocks from my ICD in Dec 2019. I had complained about vision problems after starting the med, but my EP didn't say much about it and I didn't make a big deal of it, as it was listed as a side effect and I figured it was more important to take the med for my heart. He called me recently and told me to stop the drug immediately. If you are having vision problems on Corlanor, or if you are taking Corlanor, please speak to your EP right away about this drug. My EP told me it had not been studied thoroughly enough. Reading about the drug, I did find it had been 'fast tracked'. He instructed me to get my eyes checked, so I've got an appt in a couple of weeks.
