Frequently asked questions
How does this checker work?
It pulls the interaction and warning sections printed on each medicine's official FDA label. It shows safety information per drug.
Does it check one drug against another?
Not as a full pairwise engine – it shows each medicine's own label warnings. Always ask a pharmacist to check specific combinations you're taking.
Are supplements and herbal products included?
Usually not, unless they have an FDA drug label. Many supplements interact with medicines, so mention everything you take to your pharmacist.
Is this a substitute for medical advice?
No. It's for general information. Your pharmacist and doctor know your full history and can give safe, personal advice.
