DHEA is not available in the UK
It is not a disease modifying medicine for treating lupus but an OTC supplement that might be used as an addition to other medications.
Studies have shown that it can reduce the need for steroids and may increase general well being. It has also been reported to help reduce flares and nasal and mouth ulcers muscle pain and hair loss Levels are often low in lupus patients so sometimes it is used only to bring levels up to the norm.
It's important to obtain it from a thoroughly reliable source, often a compounding pharmacy where you are guaranteed quality and consistency. As a supplement the FDA has no regulating control over it.
As far as I know, long term side effects are not yet well established. Some possible side effects - facial hair growth, acne, mood swings, voice deepening - are unacceptable. There are also reports of even lower doses like 25 mgs lowering good cholesterol (HDL) levels.
A synthetic version was developed called Aslera or prasterone ('GL171' in the studies) but the FDA demanded further studies before approving it.
I don't know where the approval process has got to at present.
It should be taken under medical supervision in my opinion with the doctor recommending the dosage.
