ToxiClear AI is a drug interaction checker powered by real FDA data, NIH databases, and advanced AI. It has two modes:
- ▸Check Mode — instantly see if your medications are safe to combine, with a plain-English explanation of the risks
- ▸Learn Mode — understand the biology behind why interactions happen, with explanations tailored to your knowledge level
- ▸History of Drug Interactions — an editorial deep-dive into the discoveries, tragedies, and breakthroughs that shaped modern pharmacology. Explore 10 eras of drug interaction history from ancient observations to AI-powered detection, with real historical photographs, primary sources, and newspaper archives.
Free tier covers OTC medications, alcohol, and the full History section. Premium unlocks prescription drugs, supplements, personalized health profiles, and curriculum-aligned educational content.
Every interaction analysis pulls from four trusted sources:
- ▸OpenFDA — official FDA drug label warnings and interaction data
- ▸RxNorm— NIH's standardized drug naming database that normalizes brand and generic names to ensure accurate matching
- ▸DailyMed— the FDA's most comprehensive label database, with detailed warnings and interaction sections updated directly by manufacturers
- ▸PharmGKB— Stanford's pharmacogenomics knowledgebase containing curated drug interaction and gene-drug association data
- ▸Groq AI (Llama 3.3 70B) — one of the most advanced language models available, used to synthesize all database findings into clear, level-appropriate explanations
Your inputs — drug names, amounts, application method, and optional context — are all factored into every analysis. Nothing is stored without your permission.
Know before you take. Understand the science behind your medications.
History is free — no account needed

- ▸Plain-English explanations written at your level — not medical jargon that requires a degree to understand
- ▸Biology education built in — Learn Mode explains the actual science behind why interactions happen
- ▸Application method matters — topical vs oral vs inhaled can completely change an interaction, and we account for that
