supraventricular tachycardia
"I started 25 mgs of this drug on 1/16/2017 around lunch time and by dinner I was having esphogael spasms that I mistook for heart issues and my swallow reflex got progressively worse and by Friday of that week was choking on chicken broth. I've never had a problem eating or swallowing in my life. The cardiologist I was seeing ignored me and said that's not a side effect. After two ERr trips w what felt like my throat closing was told to half the pill and wean off, because the drug was causing my issues. I took it for 3 weeks and have been off now now for 10 days but still can't eat. had an endoscopy and they found there is little to no pressure in esophagus & attribute this to the drug. Terrified I'm permanently damaged."
