Psoriasis treatment options after UVB

[Margaux]

Having received narrowband UVB treatment since the 1980s for chronic widespread psoriasis, I have now been told by the hospital that they cannot authorise any further UVB treatment as I have exceeded the safe limit. They say medically they cannot continue even although it works well for me and clears the condition and I have never shown any signs of skin cancer. They are now saying that I must consider Fumaerm or Biologics and I am understandably concerned re any potential side effects or long term effects they may have. At least with UVB I KNOW the risks as they have been tried and tested over the years also with such excellent developments on the treatment of skin cancer if caught early I really would like to continue but can't as my doctors are now refusing to give me that option. Has anyone else out there been in this position, any feedback would be very welcome.
