The World Anti-Doping Agency (WADA) has published its Prohibited List for 2025, and the ITIA is reminding players, coaches and their support teams to be aware of changes to the list of banned substances – which comes into effect from 1 January 2025.

The List is available by clicking here, and includes a number of modifications from the 2024 version. The ITIA will work with everyone on the tennis tour to ensure that players, and those advising them, understand the changes to the WADA Prohibited List in 2025. Relevant changes to the List include the following:

- Further examples were added to the following substance classes to help athletes and their entourage better identify prohibited substances:

S0. Non-approved substances, 

S4. Hormone and metabolic modulators, 

S5. Diuretics and masking agents, and 

S6. Stimulants.  

- The dosing intervals of formoterol have been changed, though the maximum daily delivered dose remains the same.

- Donation of blood and blood components including by apheresis are no longer prohibited if performed in an accredited collection centre.

- Hydrafinil is now classified as a non-specified stimulant.

- It is clarified that guanfacine is not a prohibited substance.

As part of its strategy, the ITIA  prioritises Education and Support and Engagement. As such, the organisation will – in partnership with its members - deliver a mixture of direct communication, education, and visual reminders in player-facing areas at tournaments to ensure that players are fully aware of the changes ahead of the 2025 season.

Karen Moorhouse, ITIA Chief Executive Officer, said: “It is vital that all players and their representatives are aware of the Prohibited List.

“The ITIA believes that the vast majority of tennis players compete clean. However, the World Anti-Doping Code is clear that inadvertent or unintentional presence of a banned substance can carry significant consequences, and we have a collective responsibility to work together to avoid unintentional doping violations.  

“This year’s changes are not significant from a tennis perspective, but we encourage all players and their support teams to talk to us if they require any clarification, support, or further education on the Prohibited List ahead of 2025.”

Players or their entourage can contact the ITIA directly through our App, via direct message on social media, or using this contact form.
