Pillplexity helps you understand and keep track of your medications and supplements in simple, clear language. Point your camera at a prescription label to instantly see easy-to-read explanations of what your medication is used for, what it's commonly prescribed for, and the difference between brand and generic names. Add your vitamins and supplements too, and see what they're commonly used for. Pillplexity is designed to make complex drug and supplement information more accessible and easier to understand. When two things you've saved are known to interact — prescription, over-the-counter, or supplement — Pillplexity shows you an educational flag with a plain-language explanation. Every interaction entry is traceable to a public FDA label or NIH source you can check yourself.
