Photosensitization to lipid-lowering fibric acid derivatives are rare.
We report a case of photoallergy induced by fenofibrate, proved by a
positive UVA photopatchtest. Evolution towards persistent photosensiti
zation is probable, since photobiological abnormalities persisted duri
ng four months after fenofibrate was discontinued. The fact that patch
tests to various benzophenones were negative is not in favour of the b
enzophenone group being responsible for the photosensitization reactio
n.
