Should I start my second course?

I have finished my first course of isotretinoin since december 2015, so it's been about 6 months already since I stopped. Now, Acnes are starting to break out again. It's not serve , but I worry that it would be grow more. My questions are : First : shoul I start my second course? Second : since my weight is 40kg , so I should take 20mg per day, but I only have isotretinoin 10 mg , therefore can I take 2 capsules of isotretinoin 10 mg at the same time? Thank you in advance :)
