As any human being athletes may face illness or injury during the sporting activities. So they may need to use a substance or method on the prohibited list because of a legitimate medical condition.

Therefore, athletes shall apply for a therapeutic use exemption (TUE), when they require using medication containing prohibited substances or methods due to a medical condition. And ETH-NADO may review and respond for the TUE application based on the International Standard for Therapeutic Use Exemption and its rules.
