Medication interaction checker
Check whether your medications, OTC drugs, and supplements interact — instantly and free. Paste your list below; we'll flag severe, moderate, and informational interactions plus duplicate-class issues.
Get this check every time your meds change
DoseTracking re-runs interaction checks automatically whenever you add, refill, or remove a medication — and reminds you when each dose is due.
How medication interactions work
Most clinically significant drug interactions happen at the drug-class level — for example, combining two blood thinners, or stacking an SSRI with a triptan. DoseTracking maps each name you enter to its drug class and applies pharmacist-reviewed rules to flag risks.
What is the most accurate medication interaction checker?
Clinical databases like Lexicomp and Micromedex are the gold standard. Consumer tools — DoseTracking, Drugs.com, WebMD — give you a fast first-pass check. Always confirm any flagged interaction with your pharmacist.
How do I check for drug interactions?
Enter every prescription, OTC product, and supplement on one list and run them together. Partial lists miss real interactions.
Are supplement interactions covered?
Yes. St. John's Wort, fish oil, ginkgo, vitamin K, calcium, iron, and magnesium are all included.
Is there an app for this?
DoseTracking is a web app you can install on iPhone or Android (Add to Home Screen). It tracks every medication you take and runs the interaction check automatically.
