Hi, I was having continuous red bumbs on skin so my doctor prescribed Accutane (Acnezac - 20) for 15 days I took it but it those bumbs came back..I had no major side effects from Accutane back then Recently I visited (around 4 months later) another doctor who prescribed Acnine-20..and within 7 days of taking it I feel I'm urinating more frequently and my face appear darker than my usual complextion. Please help if I should switch to previous Accutane tablets or stick to this one
