American Porphyria Foundation - Safe/Unsafe Drug Database

The database contains expert assessments of the potential of drugs to provoke attacks of acute porphyria. The database provides guidance based on a very careful evaluation of international clinical experience, published case reports, previously published drug lists, and theoretical considerations. The quality of patient reports used in the assessments is however often unsatisfactory and for most assessments the available clinical evidence is scarce. In addition, the theoretical models for the mechanisms of action of drugs in the porphyria disease are still incomplete.
