Why can't I check my supplements using Global DRO?

Global DRO provides information on licensed medicines and ingredients only.  Due to the different regulatory requirements of the supplements industry, Global DRO cannot provide any information or assurances regarding supplements products.  UK Anti-Doping has sought to help athletes assess the risks associated with supplements through their position statement which can be found at www.ukad.org.uk.


I have checked my medication and it is prohibited.  What do I need to do now?
If the medication you are looking to take is prohibited you should;
  1. Check with your medical advisor to see if there is an alternative medication that is suitable for you to take that is not prohibited
  2. If no alternatives are available, check with the National Governing Body of your sport to see if you are required to make an application for Therapeutic Use Exemption (TUE). For more information regarding the TUE process please visit the UK Anti-Doping website https://www.ukad.org.uk/athletes/tues.


What is the reference number that appears on the results page?

The reference number is an 11-digit number that provides documentation and proof of your search.  You should save the outcome of your search by printing out the results page and/or recording the reference number.  Using this reference number, we will be able to recreate and review the same results of this search at a later time if needed. What do the WADA Classifications on the results page refer to?

The World Anti Doping Agency divides the substances and methods included in the Prohibited List into classes based on similarities in chemical structure and benefits, or purpose.  These are identified as a substance or method with either an “S” or “M.” Examples include "S1. Anabolic Agents", such as anabolic steroids, or "M1. Enhancement of Oxygen Transfer", such as blood doping. The List also includes a “P” classification for substances prohibited in particular sports.

Why does a drug’s route of administration matter?

The prohibited status of some substances is entirely dependent upon the route by which it is administered. How a drug is administered, or its route of administration, affects how much of it is available to the body, and thus, the benefits of use. Typically, drugs administered by a systemic route (e.g., oral, intravenous injection) are very potent with possible targets throughout the body, whereas a topical application (e.g., eye drops, skin cream) have a localized target and are not likely to impact anywhere other than the region applied. Other routes of administration fall between these categories.

The results from my search said that my medication is permitted by intravenous injection, but there was a note saying that it is prohibited by intravenous infusion. What’s the difference?

An IV infusion is the supply of fluids or other liquid substrates through a vein. It is achieved by inserting a specialized needle into a vein and infusing fluids at a predetermined rate from a reservoir usually situated above the level of the body. By comparison, an intravenous injection is the supply of a considerably smaller volume of fluid or medication, but in a rapid manner, by means of a simple syringe (from WADA document https://www.wada-ama.org/en/resources/science-medicine/medical-information-to-support-the-decisions-of-tuecs-intravenous). Intravenous, or IV, infusions are included on the WADA Prohibited List for several reasons:


  • Athletes may attempt to manipulate their haematocrit or haemoglobin levels.
  • Athletes may use IV infusions to administer prohibited substances.
  • Athletes may use IV infusion to facilitate the unsafe practice of rapid rehydration.

Intravenous infusions and/or injections of more than a total of 100 mL per 12 hour period is a prohibited method, except for those legitimately received in the course of hospital treatments, surgical procedures or clinical diagnostic investigations.

Why are there seven countries to choose from on the Global DRO page?

Global DRO is a resource database of medications currently available in the Australia, Canada, Japan, New Zealand, Switzerland, UK and USA. Each country has its own regulatory policies to approve medications and not all medications are available in all countries.  The Brand name medications represented in each country’s Global DRO database reflects the medications available in that country.  

Eventually we hope to provide this resource to other countries as well. If you’d like more information on this option, please click the “Feedback” icon.

I can’t find my question on this list.  What should I do?

To get an answer to your question, you should use the “Feedback” link on the Global DRO home page or the "contact us" link at the bottom of the page.


What is meant by Prohibited Out-of-Competition?

Out-of-competition testing is defined by WADA as any testing “not in-competition”. Such testing can occur at any time of the year and at any location, including at home, place of training, or even overseas. UK Anti-Doping’s out-of-competition testing takes place with no advance notice.


What is meant by prohibited In-Competition?

In-Competition testing is conducted in connection with a sporting event.  The WADA code defines In-Competition as "the period commencing twelve hours before a Competition...through to the end of such Competition and the Sample collection process related to the end of such Competition", unless stated otherwise by the rules of an International Federation (IF) or other related Anti-Doping Organisation.  During this time athletes should not have any substance that is 'prohibited In-Competition' in their system - this is regardless of when the substance was administered.
Athletes should familiarise themselves with the rules each competition as defined by the IF or National Governing Body (NGB).
