Compensating for high heart rate when calculating zones?

allroundthesun

My average resting heart rate is 111 (due to a medication I take which raises heart rate as a side effect; no I can't stop taking it; yes, my doctor is aware of my heart rate), which is obviously higher than the normal/healthy zone. Since my resting heart rate is so high, do I need to make adjustments to the standard calculations for determining moderate, fat burning, aerobic and anaerobic heart rate zones? If so, does anyone know the percentages I should be using under the circumstances? Thanks in advance if anyone knows.
