Whoever is treating you with the isotretinoin regime mentioned, is at least quite forward thinking and has thrown aside the old understanding that HIGH dose = good.
The dose is so low that it is known to be fairly safe.
In fact I am taking 10mg every fortnight myself for a continued oil control and my cholesterol and liver panels are normal.
However some guys would be concerned pertaining to reproduction (whether it would increase the risk of fetal abnormalities). You can stop 3-6 months prior to your family planning and all should be good.
Meanwhile ensure your skin care products are suitable and you can eventually tail off your medications!
