Hi,
You are right, that both of these are the same ingredients that is
isotretinoin. The daily dose of isotretinoin is 0.5 mg to 1 mg / Kg body weight / day. However, in severe
nodular acne, this dosage may be up to 2 mg / Kg body weight / day. Therefore, depending on his body weight, this dose can be definitely increased to 80 mg / day, if it is well tolerated.
As, I have told that these are the same ingredients, therefore, there should not be any problem in switching from one to another. Though, the choice of prescription of one or the other, out of these two depends on the preference and experience of the prescribing doctor. Still, analyzing the reviews,
Claravis has more better reviews than Absorica.
Take care. Hope I have answered your question. Let me know if I can assist you further.
