Hi @azogby I was on this for a couple of years back in 2016-2017. I had been on 2 other drugs prior to that Amiodarone and Mexiletine. My EP Doctor was having a hard time trying to control my VT and He was looking at Heart transplant as the next step which did happen in Jan 2018.
But as for your question I was pretty drugged up being on 3 different anti arrythmia meds and even my Pharmacist was questioning it. So Im not sure Im typical. But it along with the other 2 keep me going for a couple of years and I don't remember any side affects for that particular med. Its been around for a while as that was almost 10 years ago.
