Drug Interaction API
The Interaction API is a web service for accessing drug-drug interactions.
The Drug-Drug Interaction API will be discontinued on or about January 2, 2024. RxNav's Interactions tab will also be removed.
Currently, the API uses two sources for its interaction information - ONCHigh and DrugBank.
ONCHigh is a list of high-priority drug-drug interactions derived by a panel of experts and contained in a JAMIA article. ONCHigh is updated using CredibleMeds with drugs that have a known risk of Torsades de Pointes (TdP).
DrugBank drug-drug interaction information is drawn (unmodified) from the non-commercial version of the DrugBank database, which does not carry severity information. See the DrugBank license for more information.
The drug-drug interactions are updated monthly, usually on the first Monday of the month.
Use of the API is subject to Terms of Service. No license is needed to use the Interaction API.
