The drip ban is a volume limit doing a doctor's job

Anti-doping rules cap infusions at a set amount over a set window, and the number does not care why the fluid is needed.

Fifty millilitres per six hours, unless received in hospital, during surgery, or in clinical investigation. That is the shape of the prohibition on intravenous infusions, and it is one of the few anti-doping rules where the offence is a method rather than a substance.

The rationale is sound and worth stating properly. An intravenous drip can mask a prohibited substance by diluting it, can rapidly restore plasma volume in a way that alters blood parameters, and can deliver permitted substances at concentrations that amount to something other than nutrition. Ban the route and you close all of that at once, without having to litigate what was in the bag.

Now consider the athlete at the end of a hot event who is genuinely depleted and vomiting. Oral rehydration is the correct first answer, medically and under the rules, but there is a real category of case where it does not work fast enough, and the rule says a clinician may act only within the exemption or by hospitalising the patient. In practice, teams solve this by taking the athlete to hospital, which is the correct legal route and an absurd use of an emergency department for a problem the team doctor could manage in the medical tent.

The exemption process exists for this and it is retrospective in emergencies, which means the treating doctor makes a decision knowing the paperwork will be judged later by people who were not in the tent. I have never met a team physician who found that comfortable.

There is an enforcement inconsistency underneath it too. The volume threshold is administered as a bright line, and bright lines are easy to police and blind to context. A hundred millilitres is a violation whether it was a recovery drip in a hotel room or a clinical necessity in a stadium, and the difference is then argued afterwards by lawyers.

Keep the ban. It closes a genuine loophole and there is no version of the rule that relies on trust which would survive a season. But give accredited event doctors a defined on-site authority, logged and audited, so the choice is not between breaking a rule and calling an ambulance for dehydration.
