Will a second course of roaccutane help me to get rid of acne forever?

hi im 22years old male. about 4 years ago i used raccutane-roche 40/mg per day for about 8 mnth and it cleared up my skin ( i was 75 kg and i hade severe cystic acne ) now after 4 years i went to gym and after 3mnth of workout my acne relapsed but it wasnt that bad so i quickly called my dr and my derm put me on the 2nd course of isotertinoin(geni-tret made in greeck) 40mg per day and this time i feel heart palpitation.i dont know its iso or not. doese second course kill my acne for ever?
