How much of a cumulative dose would you expect for someone who is 65kg and has truncal acne?

I understand that everyone is different. However, can you give me a range? By my calculation it would be 2mg/kg over around 5 months ( Say 150 days ), which is 2*65*150 = 19500mg over the whole course.

Hi. I presume you're referring to isotretinoin. The recommended cumulative dose is 120 to 150 mg/kg.
