DecodeRx
CPIC Medication-Gene Guide
Free · Designed for iPad. Not verified for macOS.
Understand how your genetics may influence 39 common medications. Built on CPIC clinical guidelines, the gold standard in pharmacogenomics. Free, offline, private.
Your genetics may influence how medications are processed by your body and DecodeRx helps make that science easier to understand.
Built on published CPIC (Clinical Pharmacogenetics Implementation Consortium) guidelines, DecodeRx is an educational reference that maps 39 commonly prescribed medications to the pharmacogenes involved in their metabolism. Whether you've already received pharmacogenomic test results or you're new to the topic, DecodeRx presents evidence-based information in a clear, clinical interface — entirely offline, with no account, no upload, and no data collection.
PERSONAL PHENOTYPE MODE
If you have a pharmacogenomic test result, you can record your metabolizer status (Poor, Intermediate, Normal, Rapid, or Ultrarapid) for each gene the app covers. The medication library then highlights what's most relevant to your phenotypes and the detail screen pins the matching CPIC guidance to the top, so you can see in one tap what published guidelines say about your phenotype and a given medication.
Your phenotypes stay on your device. They are never uploaded, shared, or collected.
REFERENCE CARD
DecodeRx can generate a clean PDF reference card summarizing your entered phenotypes and the medications they affect, ready to print or share with a healthcare provider via the iOS share sheet. Generated entirely on-device.
EVIDENCE-BASED FROM THE GROUND UP
DecodeRx draws from CPIC Level A and Level B gene-drug interaction guidelines, the gold standard in pharmacogenomic clinical practice. Every effect summary is grounded in published clinical literature, paraphrased for clarity.
39 MEDICATIONS · 9 PHARMACOGENES · 7 CATEGORIES
Browse medications across Psychiatric, Cardiovascular, Pain, Gastrointestinal, Oncology, Immunosuppressants, and Other categories. For each medication, DecodeRx surfaces the relevant pharmacogenes — including CYP2D6, CYP2C19, CYP2C9, VKORC1, SLCO1B1, DPYD, TPMT, NUDT15, and CYP3A5 — and explains what each metabolizer status (Poor, Intermediate, Normal, Rapid, Ultrarapid) may mean for that drug.

Find what you're looking for instantly — clopidogrel or Plavix, sertraline or Zoloft, tamoxifen or warfarin.
PRIVATE BY DESIGN
DecodeRx makes no network requests of any kind. There are no analytics, no third-party SDKs, no advertising identifiers, and no accounts. All content is bundled with the app at install time. Phenotype data and the optional name you enter for your reference card stay only on your device, and you can delete them at any time.
COMPLETELY FREE
No in-app purchases. No subscriptions. No ads. No upsells. Just a free educational reference tool.
DESIGNED FOR CLARITY
DecodeRx is an educational reference. It does not provide medical advice, diagnosis, or treatment recommendations. Always discuss medication decisions with a qualified healthcare professional.
