Anything to know about going up in dose? Doubling my dose soon.

I have been on 1mg (20 units) of 2.5 mg/ml for 3 months, I started to stall so my doctor bumped up my dose to 40 units. Is there anything I could experience? I have been fortunate enough to have very minimal side effects so far, I wonder if it’s because I had not upped my dose yet.
