DID is intended to provide accurate and timely responses to queries about the status of licensed pharmaceutical products and over the counter medicinal products available in the United Kingdom, in relation to the Olympic Movement Anti-Doping Code. Athletes are advised to check all medications with their team doctor or medical officer, especially when travelling abroad as some familiar brands can and do contain different substances. This service does not provide counsel on medication or dosage and the database cannot search for herbal or nutritional supplements. For more information on the use of supplements in sport please see the "supplements" page. Whilst every effort has been made to ensure the information provided on this site is correct there can be time delays between the change in status of a given substance and the subsequent data updates.
