In some situations, an athlete may have an illness or condition that requires the use of medication listed on the World Anti-Doping Agency’s Prohibited List. USADA can grant a Therapeutic Use Exemption (TUE) in these situations in compliance with the World Anti-Doping Agency International Standard for TUEs. The TUE application process is thorough and designed to balance the need to provide athletes access to critical medication while protecting the rights of clean athletes to compete on a level playing field.
