CYP450 Genetic Polymorphisms: Generalized Tonic-Clonic Seizure after Intentional Fluoxetine and Melatonin Overdose

S D Med. 2023 Jul;76(7):305-308.

Abstract

Cytochrome P450 polymorphisms have gathered much attention regarding personalized psychopharmacological care. It is well documented that these drug metabolizing enzymes lead to interpatient variability in pharmacokinetic profiles. It appears that less functional genotype may increase of risk of higher side-effect burden. Here we highlight the importance of genetic polymorphisms to potentially predict a toxicity related phenotype after an intentional overdose. Genotyping may have a role in predicting serious side effects to help clinicians educate patients and their families, and implement more intensive monitoring and institute prophylactic treatment as needed.
