My GP gave me 40mg of Sotalol as a PIP and told me to take one tablet when necessary. My Afib problem is rhythm control. I did some research and found out that Sotalol can help with rate and rhythm problems BUT you have to take it at a high dose for it to help with rate control. It can also cause dangerous ventricular arrhythmias. I have used it once but it didn't help much. Anyone using this to help with rhythm problems.
