## Description

Interaction Checker is a free online tool for checking potential interactions among drugs, supplements, foods, and alcohol. Users can add items to a list and review reported interactions, with each result quoting the relevant FDA label. The source information comes from FDA labels on DailyMed, helping users see the labeling behind a result rather than relying on an unexplained summary.

The checker covers a wide range of combinations, including prescription medicines, common supplements, foods such as grapefruit, and alcohol. Examples featured on the site include interactions involving ibuprofen and lisinopril, warfarin and aspirin, or levothyroxine and calcium. The site also offers a drug information guide, a supplements section, and access options including an API and MCP server.

Interaction Checker states that it requires no account, displays no ads, and does not track a user's list; the list remains in the browser. The interface is available in several languages. The service emphasizes that its information is not medical advice, so users should consult a qualified healthcare professional about medication questions.
