… you have a good chance that your acne will relapse. Studies have shown that 120 mg/kg total (not daily) was needed to give you your best chance of keeping acne away for ever. If you take at least 120 mg/kg (your conversion factor is 220 lbs = 100 kg. To calculate how much you need do the following:
your_weight(lbs)*(100/220)*120= total amount needed for treatment
The cool thing is that it appears you can take low doses over long periods of time and have it be just as effective as taking a high dose over a shorter period of time
The statistical breakdown if you meet the 120 mg/kg body weight is as follows
Patients using isotretinoin for the first time should be given a minimum total dose of 120 mg/kg, otherwise recurrence rates will be high. If such a minimum dose is administered and the follow-up is 3 years, then the patient has approximately a 39% chance of not having recurrent acne, a 17% chance of having acne severe enough to require topical therapy, a 25% chance of needing the use of oral antibiotics plus topical therapy, and a 19% chance of needing more isotretinoin. Patients younger than 18 years are more likely to experience a recurrence. On average, females who receive their first course of isotretinoin are older than males.
I’ve been reading a lot of posts where people are slacking off taking their accutane at the end of their treatment because they’ve got clear skin and it makes them ache or whatever. You do this at your own risk–you have been warned 🙂
