Abstract
The efficacy of oral beta-carotene for the prevention of photosensitivity symptoms in erythropoietic protoporphyria was studied in a controlled cross-over trial in which it was compared with a placebo. No significant difference was found between the 2 preparations. Patients' symptoms showed statistically significant association with sunlight hour records.
