Frequently Asked Questions
- Is this drug interaction checker free?
- Yes. The interaction checker is completely free and doesn't require an account or login. You can check as many medication combinations as you like.
- Where does the interaction data come from?
- Interactions are compiled from public FDA drug labeling and other public sources. Each result shows a severity level, the mechanism, and general clinical guidance.
- Does a “no interactions found” result mean the combination is safe?
- No. It only means we don't have a documented interaction for that pair in our database. Always confirm with your prescriber or pharmacist before combining medications.
