IV Infusions: Explanatory Note

UPDATED: December 2, 2021

USADA IV Infusions

*Information reflects the most current Prohibited List.

The World Anti-Doping Agency Prohibited List (WADA Prohibited List) specifies substances and methods that are prohibited in sport, including substances and methods that are prohibited in-competition only, as well as those that are prohibited at all times.

Below is important information about the IV rule, why IVs are prohibited, and how athletes can best protect their health and safety.


 What is an intravenous (IV) injection or infusion?

An intravenous injection or infusion occurs when a substance is given directly into the vein through a needle. It could be delivered in a small volume with a simple syringe, or in a large volume through a specialized needle, tubing, and an IV bag.


Are IV injections or infusions prohibited?

Intravenous infusions and injections are prohibited as a method both in-competition and out-of-competition if the volume delivered exceeds 100 mL within a 12-hour period. This is true even if the substance being injected is permitted (e.g., saline), and this is also true even if the athlete receives a number of small volume injections. If the total volume received will exceed 100 mL in 12 hours, then it is prohibited and a Therapeutic Use Exemption (TUE) may be required.

If the substance being injected is prohibited, then TWO TUEs are needed: one for the IV volume of more than 100 mL in 12 hours, and one for the prohibited substance.


Why are IV infusions/injections prohibited?

IV infusions/injections are prohibited because they can enhance performance by increasing plasma volume levels, mask the use of a prohibited substance, and distort the values of the athlete biological passport.


In what situations is a TUE required for an IV infusion/injection of more than 100mL?

Unless there is an emergency, a TUE is required in advance for IVs in the following situations:

  • In a medical practitioner’s office, clinic, suite, home, tent, hotel room, or vehicle
  • In any type of health clinic, health center, wellness clinic, or any kind of IV clinic, dialysis center, or treatment room outside of a hospital facility that is not part of a surgery or diagnostic test
  • In an event organizers’ medical facility, tent, first aid station, polyclinic, or start-finish line facility (but also see the section on emergencies)
  • During home visits by IV services of any type, or using your own IV equipment at home
  • Receiving IV infusion therapies, cleanses, detoxes, refreshes, food poisoning/jet lag/hangover cures, flu relief, or antioxidant therapies from boutique or concierge IV clinics, regardless if you are in the clinic or in your home or hotel room

Keep in mind that sometimes hydration clinics sponsor sporting events and set up tents to provide IV services to athletes. Just because an IV service is offered at a sporting event doesn’t mean it is ok to use. It is still a prohibited method!


Are TUEs ALWAYS required before receiving an intravenous infusion or injection?

No. If the IV infusion/injection is less than 100 mL, it is not considered a prohibited method and no TUE is required for the method. However, the athlete still needs to check the anti-doping status of the substance being injected.

Furthermore, no TUE is required if the IV infusion/injection is more than 100 mL in 12 hours but is received:

  • in the hospital or emergency room
  • as part of urgent medical treatment in an urgent-care or after-hours clinic that is part of a hospital or a hospital system
  • as part of a surgery/surgical procedure (in or out of the hospital)
  • as part of a diagnostic procedure or test (in or out of the hospital) like an MRI or CT scan


What if I need an IV in an emergency?

In an emergency, athletes should always receive medical care first, and then notify USADA afterwards. Athletes should obtain medical notes or records relating to the emergency treatment to submit with their emergency TUE after the emergency has subsided.


When is the use of an IV infusion or injection permitted?

IV injections of small volumes (less than 100 mL) of a permitted substance do not require a TUE in advance, such as small volume injections of B-vitamins or iron. Please be sure to check that the TOTAL volume does not exceed 100 mL. For example, in the case of an iron infusion, the amount administered includes both the saline and the iron.


Are there health risks associated with receiving IVs?

Yes, there are potential risks and complications that come with receiving an IV, including infection, cellulitis, inflammation of the wall of a vein with associated thrombosis, bleeding, hematoma/arterial puncture, unintended leakage of solution into the surrounding tissue, air embolism, and needle stick to the provider. Inappropriate levels of electrolytes given by IV can also have serious cardiac, muscular, and nervous system effects, even resulting in death.


Are IVs better than drinking water for rehydration?

The American College of Sports Medicine consensus guidelines state, “IV fluids do not provide an advantage over drinking oral fluids and electrolytes.” Normal rehydration can be achieved in the vast majority of individuals by drinking and eating normal beverages, such as sports drinks and water, and meals. Various sports and athletic organizations such as the American College of Sports Medicine (ACSM), the National Athletics Trainers’ Association (NATA), and others have informative resources to educate on best practices for fluid replacement in athletes.
