Scan · Autocomplete · Check

Autocomplete across 50,000+ drug names. Point your camera at any pill bottle. Check up to 20 medications in one go.

How It Works

  1. 1Type or scan your medications. Start typing any drug name and our autocomplete resolves it to the exact RxNorm ID — no typos, no ambiguity. Or tap the camera icon to scan a pill bottle label.
  2. 2Add up to 20 drugs at once. Unlike most checkers that only handle 2, we compute every possible pair combination — so nothing slips through.
  3. 3See severity-ranked results instantly. Contraindicated interactions surface first. Every result links to its original FDA label — not a summary, the actual source.
