Changes to the Prohibited List 2021


The World Anti-Doping Agency (WADA) has published its updated Prohibited List of Substances and Methods which will come into force on 1st January 2021. For 2021, there have been several changes to the overall document design and some updates to the status of some substances already included on the List. The WADA List Expert Group reviews and revises the List annually, considering submissions from Stakeholders, advances in scientific and medical research, information on doping practices etc. A substance or method is added to the List if it meets two of three criteria: it has performance-enhancing potential, poses a danger to athletes’ health or its use is against the spirit of sport.


Redesigned List


The WADA List has been redesigned to be more ‘athlete friendly’, and now incorporates a table of contents and an index, this should allow for easier navigation of the document by athletes and other users. For clarity and accessibility an introduction has been added to the document that explains some of the terminology used in the List.


Changes of note to Prescribers based in Ireland include:

S3. Beta-2 Agonists


Inhaled Vilanterol is now permitted up to the manufacturer’s maximum recommended dose of one puff per day (25 micrograms). The dose is expressed as the metered dose of 25 micrograms which is equivalent to a delivered dose of 22 micrograms.


WADA also wish to highlight the following change which will be implemented in 2022:

S9. Glucocorticoids 2022


WADA have also announced that from January 1st 2022, all injectable routes (e.g. intravenous, intramuscular, periarticular, intra-articular, peritendinous, epidural etc.) of administration of glucocorticoids during the In-Competition period will be prohibited. To use a glucocorticoid by any injectable route In-Competition will be prohibited and will require Therapeutic Use Exemption (TUE) Approval. This change has been flagged to allow time for Doctors, Athletes and their support personnel to familiarise themselves with these new changes. Glucocorticoid treatment is not prohibited Out-of-Competition. However, glucocorticoid can remain in the system up to and during competition periods. Detailed washout periods for various glucocorticoids will be published to aid Physician decision making regarding treatment options and TUEs.


P1: Beta blockers

Nebivolol has been added as further example of a beta blocker prohibited in specific sports.


Dr Una May, Sport Ireland’s Director of Participation and Ethics stated “Sport Ireland welcomes the more athlete friendly version of the List and is happy to reassure all athletes and athlete support personnel that the most recent updates will be reflected in all of our Educational resources”.
