Can I reuse a roaccutane dose?

I'm asking about reusing roaccutane for the third time, I used it on first time in 2010 with dose of 40mg for 6 months and all things went good till year 2015 acne started to appear especially under skin, I repeated the course with 20mg dose. But now the acne come back again in extensive way and under skin too. I am thinking of reusing it for a full course in 20mg dose. Is that possible?
