About Pharmacogenetic Testing

CYP2C19 has an impact on the efficacy and side effects of Onfi because it is primarily responsible for its metabolism in the body. Individuals with low CYP2C19 activity, known as “poor metabolizers” are at high risk of experiencing side effects and lower dose are recommended compared to normal individuals (Pharmacotherapy “Pharmacogenetic Testing for Neuropsychiatric Drugs” February 2014). CYP2C19 testing can be valuable tools to offer individualized Onfi therapy.

 

The trial-and-error process of medication treatments has caused a great deal of problems in the United States. It has led to medication addiction, ineffective treatment and hospitalizations. Genetic testing aims to stop this problem by testing the patients DNA and seeing how the medicine interacts with those genes. Once this is understood, the patient can make an informed decision and decide whether the drug is right for him.
