Unsafe Drug List
ABOUT THIS UNSAFE DRUG
LISTING:
The pharmaceutical listing
contained herein has been devised without reference to language, societal, cultural, dietary, prescribing or dispensing conditions
[including those imposed by law], other than those of the United States, which might affect the information provided.
This list of pharmaceuticals
contains only the listing of drugs known to be UNSAFE or considered potentially to be UNSAFE for porphyrics.
Listing of the pharmaceuticals
on this site are due to the actions,precautions, side effects, or interactions of the given medication in relation to porphyria
patients, or the drug's action in regard to cytochrome P-450 and it's metabolism in the liver.
The listing of these
pharmaceuticals is not intended as medical advice for individual problems. It is provided only for porphyria patients making
an evaluation as to the risks and benefits of taking a particular drug.
The potential for various
drugs triggering attacks of acute porphyria is based primarily on clinical evidence. Some conclusions are based upon tests
with animals with experimental porphyria.
The information about
drugs contained in this database is general in nature and is intended for use as an educational aid. It also does not cover
all possible uses of a said medicine.
*Be reminded that a specific
drugs may work well for one porphyria patient and not for another usually due to other existing medical conditions of the
particular patient.
Porphyria patients and
their physicians must make their decisions on the use of medications appropriate to their own circumstances and in view of
other existing medical conditions.
The following unsafe
drug list must serve only as a guide since individual patient reactions to specific drug is complex and unpredictable especially
with other existing conditions both related and unrelated to the various porphyrias.
Because many new drugs
have not been tested, such drugs should be avoided. It often takes up to five years to realize the side effects of many new
drugs on the market. If it is critical that an untested drug be used, contact with a porphyria specialist should be made before
proceeding to use the drug in question.
Drugs marked with an
asterisk * have been documented as associated with acute attacks of porphyria.
* Indicates that there is evidence that the drug has induced porphyria.
