It is called Mexiletine. I take a 150 mg tablet. Which I was told was low dose.

Back in 2015 I had 5 shocks of my ICD/Pacemaker and went to ER. There the cardilogist put me on a drip of Amiodarone. It did work and my tachyacardia stopped along with my PVCs.

But I became concerned with the toxicity of the drug and the fact my EP had not put me on it the hospibital cardilogist did (this is at Mayo Jacksonville). My EP said we can try to slowy wean you off the Amiodarone and we did over several months.

My PVCs did got up but tacacarydia was only non sustanied. The PVCs kept getting worse and magnesium was not making any difference he recommended Mexiletine. He told me this drug was for tachycaria and PVCs reductions but did not have the same toxic affects of Amiodarone. Because of it low toxicity and leaves body quickly you have to take it every 8 hours.

I started taking it and my tachyacaridia reduced dramactically to just here and there for few second to none at all (my heart is monitored by my ICE/Pacakemaker which sends report to Mayo every 3 months). My PVCs were cut in half per my EP.

I hope this helped. Sorry for long post but wanted to post what got me to this medication and why.
