It is not generally recommended for lupus although it might be of some value in scleroderma.
There has to be a good reason why this treatment is not generally available and not fully endorsed or recommended by the top lupus experts, I mean apart from the wild suggestion that the whole medical and scientific world are conspiring to stop us getting the best possible treatment.
Several of us have asked our doctors about it and been given to understand that too much is as yet unknown as to the possible catastrophic reactions in individuals. If you consider the great amount of research trials and studies that take place before medications are approved by the FDA the amount of replicable research that has been done on this therapy notion is very limited indeed.
They are only just making headway on understanding how UV affects different individuals according to their genetic makeup.
I am always puzzled by the emphasis on 'natural' 'remedies' bearing in mind that this is such a complicated and unnatural disease and that many of us here would have been dead or be leading lives of unbearable suffering without modern understandings and modern medicines.
The anti malarials are not new at all. They can be highly effective in relieving fatigue especially Quinacrine / Mepacrine and when used in combination with either Plaquenil or Aralen. Generally speaking once the disease is under control fatigue lessens but just as essential is making the various adjustments to life style that lupus demands such as getting enough sleep/ rest , prioritising and eliminating, getting exercise and of course dietary adjustments as needed.
There are other posssible causes for fatigue such as poor sleep patterns as occurs in fibromyalgia and various sorts of anemia
Anyway, this treatment is for the most part not available. Most of us would never dream in a million years of starting to treat ourselves at home with homerigged equipment. It's important to make such major decisions with a full understanding of what might be at stake.
The one person I have heard of who did just that has also adopted a radical programme of various supplements and life style adaptations.
Good luck and do take good care based on the fullest possible information about all the various therapies available - and a good understanding of lupus itself and how exactly it is affecting you.
