Fumaderm dose question

[pablo11200]

Hi guys I got psoriasis from 2009 I tried all possible treatments, from February last year I'm on fumaderm.First 3 months was terrible for my stomach now is fine.Question is I been on 6 tablets,than 4 tablets and at the minute just 2.But about 6 weeks when I start take it 2 psoriasis come back on my knees and elbows and is more biggest and thickness. My consultant said that I have take bigger dose again but I had not really good blood test for liver. Maybe someone has similar situation because I take it 4 tablets from last 3 weeks and psoriasis is still the same,maybe I have to use dovobet again??
