How blue, Joe ?
Copper salts in aqueous solution take on a slight blue tinge at
concentrations above 1000 micrograms per litre and, in a female
subject, the sweat copper can go up to about 1400 mcg/l
(especially with oestrogen ingestion). This could account for a faint
blu-ish tinge to this patient's sweat.
Otherwise sweat is colourless and I'm not aware of any drugs that
have that effect, including the one suggested by Sten Ohman. So if
it's not copper, it's more likely to be an interaction with her clothing
or chemicals in it (why is she visiting the dermatologist and does
she rinse all the detergents etc out of her clothes adequately ?)
Best wishes,
