Intravenous infusions are included in Class M2 of the Prohibited List primarily because some athletes may use this Prohibited Method to:
- improve their performance by increasing plasma volume;
- mask the use of a prohibited substance;
- misrepresent the values on an ahlete's biological data sheet;
- If a substance that is not a prohibited is administered by injection or infusion in a volume greater than 100 mL over a 12-hour period and is not part of an inpatient treatment, surgical procedure or clinical diagnostic study, a Therapeutic Use Exemption (TUE) request should be submitted for that Prohibited Method.
- If the rohibited substance is administered by intravenous injection or infusion, a TUE should be requested for that prohibited substance regardless of the fact that the infusion volume may be less than 100 mL and regardless of the conditions and circumstances under which it is administered.
- In medical emergencies, a retroactive TUE may be requested in accordance with the International Standard for TUEs.
The table below provides examples of the need for a TUE request in cases where prohibited and permitted substances are used infusively.
