Hey there, don't be scared. I took accutane too and broke out throughout my course. When I came off it I was still breaking out and I didn't completely clear until about a month after I finished it. The drug is a strange one and works in an odd way but you will clear up eventually. You may even just need a little bit longer on it. One of my friends took it for an extra 3months (8 months in total) to clear up totally.

I sometimes think it's that the irritation it causes to the skin can cause a kind of pseudo acne.

If in doubt discuss your fears with you derm. It'll be ok, it doesn't stop working, it just works in a weird way.

Thanks for your reply! I'm seeing my derm this thursday! Oh something I should add,a few months ago I switched to another brand called Mylan, could this have anything to do with the problem? Maybe this one doesn't work for me or something and now that the previous brand is out of my system the acne has returned. Or maybe something just went wrong with my last box of pills... sigh, so many possibilities! Oh well..,

I wouldn't have thought that a different brand would change anything, as long as the chemical formulation is isotretinoin and that your pills are within their use-by-date then that's all that really matters. Obviously keep your pills at room temp and out of extreme heat/cold etc.

It can be the change of the brand. Although they are both isotretinoin, the formulation is not exactly the same. In generics there is an acceptable variation for the quantity of isotretinoin, so differents brands can have different concentrations, and different absorption. If the change of brand occurred just a few weeks ago, it can be linked...i guess.
