Safe/Unsafe Drug Database

This database contains expert assessments of the potential of drugs to trigger attacks of acute porphyria (AIP, VP, HCP & ADP) based on the available evidence. However, this evidence is not always complete, which may lead to some degree of uncertainty. The information in these databases is meant as guidance to health care professionals. It must be made clear that the prescription of drugs to a patient with acute porphyria is entirely at the risk of the physician in charge.

The information provided on the Safe/Unsafe Drug Database pertains only to the risk of an attack of acute porphyria associated with medication. General safety issues should be reviewed with a medical provider before a medication is taken.
