Check your medications for interactions.
Type in the drugs you're taking — prescription, OTC, supplement. We'll flag the combinations that are known to be dangerous, so you can surface them with your provider before a refill.
Generic or brand name works. Includes prescriptions, OTC, and common supplements.
Your medication list
Interactions found
0Add two or more medications to see any interactions between them.
Phase-1 preview: alert logic runs locally. Phase 2 will route to your assigned physician via secure messaging.
Rules this tool applies.
Interactions are drawn from FDA product labels and well-documented clinical pharmacology. We prioritize the ones that change dosing, require monitoring, or are unambiguously contraindicated.
Should not be taken together under any routine circumstance.
Clinically significant — usually requires an alternative or tight monitoring.
Worth flagging — dose change, spacing, or extra counseling may be enough.
Phase 1 — today
Lookups run in your browser against a curated dataset (~150 drugs, ~80 interactions). Your medication list is saved locally on this device only.
Phase 2 — planned
Clinical lookups will call DrugBank's commercial API through our backend. Your medication list will sync to your NoTimeRx profile under HIPAA-secure Firestore rules, and dangerous combinations that persist > 9 hours will alert your assigned provider.
Common questions.
This tool is educational and doesn't replace a pharmacist or prescribing clinician.
Is this a complete drug list?
No — Phase 1 covers ~150 drugs commonly seen in primary-care and lifestyle-medicine contexts, plus everything NoTimeRx prescribes. If your medication isn't here, a "not found" result doesn't mean it's safe — it means we don't have it indexed yet.
Why don't I see the interaction I was expecting?
We only list interactions that are documented in FDA labeling or consensus references. Minor theoretical interactions are excluded on purpose — they clutter real clinical decision-making.
Is my list stored anywhere?
Today: only in this browser's local storage. It doesn't leave your device. If you sign in and save your list to your profile (Phase 2), it will live in your HIPAA-compliant patient record alongside your NoTimeRx prescriptions.
Can I enter supplements and OTC meds?
Yes — many of the most-missed interactions involve OTC NSAIDs, St. John's Wort, grapefruit, and alcohol. Enter them just like any other medication.
What if my provider disagrees with a flag?
Trust your provider's clinical judgment. These flags are reference-based starting points, not override decisions. Your provider sees the full clinical picture.
