An Adverse Drug Event (ADE) is an illness resulting from the administration of a drug. An ADE could be because of an interaction with another drug, improper dosing, or because of a genetic variant in the way that an individual metabolizes a particular medication.
PGx Testing and FDA Labeling
The Food and Drug Administration has been providing guidance to drug companies to promote PGx testing to shorten development times and introduce new therapies. Product labeling has been adjusted to include genetic information to aid in dosage information of the drug.
Hundreds of common medications now offer recommendations on avoidance of ADEs when products are being prescribed.
