Prohibited Substances

The PROHIBITED LIST FOR HUMAN ATHLETES

The WADA Prohibited List ("List") for 2024 and (NEW!) 2025 are published in the Library section below.

The List is reviewed annually. The updated version comes into effect on 1 January and is published end of October of the previous year. Athletes who take regular medication must always recheck their medication against the updated List. In case they take a medication that has changed status and will be prohibited when the updated List comes into effect, they should apply for a TUE (Therapeutic Use Exemption).

Athlete support personnel should ensure they are familiar with the List and its changes.    

 
Important: a major change to the status of glucocorticoids came into effect on 1 January 2022. Please read this document carefully.

 

The World Anti-Doping Agency (WADA) publishes and maintains a list of the substances and methods which are: 

  • Prohibited at all times (both in-competition and out-of-competition); or
  • Prohibited in-competition* only (athletes can be tested for these substances or methods during the in-competition period. The substance/method is not forbidden at other times); or
  • Prohibited in specific sports only. 

Within these categories, some substances are "conditional" – athletes are allowed to take up to a specific dose or within a specific dosage range but outside of that dose or range the substance is prohibited (for example, some ingredients found in asthma inhalers). Other conditional substances are those that are only prohibited by the way they are taken (route of administration) - for example, applied as a cream, or swallowed, or inhaled.

The FEI defines the in-competition period as the period commencing one (1) hour before the beginning of the first horse inspection the day before a competition in which the athlete is scheduled to participate through to the end of the last competition at the event for that athlete or the sample collection process related to such competition.

In the Prohibited List, substances and methods are classified by category (e.g. steroids, stimulants, gene doping). The Prohibited List is updated annually and comes into effect on 1 January. It is published 3 months before earlier (i.e. 1 October) so athletes have the time to review any changes and apply for a Therapeutic Use Exemption (TUE) for their current medical treatment if necessary.

Athletes have a duty to:

  • Familiarise themselves with the Prohibited List and make sure to always be updated on the latest version;
  • Systematically ask their medical practitioners to verify that no medication, supplement or treatment they are taking (prescribed or not) involves prohibited substances or methods;
  • Apply for a Therapeutic Use Exemption if a prescribed treatment involves prohibited substances or methods;
  • When purchasing over-the-counter medication, consult their national anti-doping agency or ask the pharmacist to check that the medication does not contain anything prohibited on the Prohibited List currently in force;
  • Be extremely cautious with and generally avoid dietary and nutritional supplements; never assume that a product is safe to use simply because it is a supplement. Many supplements contain undeclared ingredients including illegal stimulants, steroids, and prescription medications.
  • Athletes can learn how to manage the risk posed by supplements. Please refer to this page for further information.
