Studies suggest wide heterogeneity in pain management response. Improved methods of pain pharmacotherapy are urgently needed to improve clinical response and safety profile of analgesics. The study or application of how genetics influence response to medications is called pharmacogenomics (PGx). PGx testing is a tool that may support more precise selection and dosing of pain medicines. PGx guidelines exist for drug-gene interactions with high levels of evidence and can be applied in clinical practice for more precise care in patients with cancer. The Clinical Pharmacogenetics Implementation Consortium (CPIC) is a publicly funded international consortium of experts who curate published PGx data and create peer-reviewed guidelines on how to translate PGx results into actionable prescribing decisions. Given the immense need to improve pain management, it is important to increase awareness and consider application of CPIC guidelines to pain management strategies. This commentary concisely describes how PGx can be used to aid in more precise applications of pain pharmacotherapy based on the CPIC guidelines.
