IV Hydration Therapy

Hospital fluid therapy as the clinical root

Intravenous fluid replacement entered medicine during the 1832 cholera pandemic. A biographical account reports that before that year doctors had speculated about intravenous therapy but none had tried it, and that Thomas Latta in Scotland performed the first infusions. The same account says the treatment faded after his death, citing general medical scepticism, limited biochemical knowledge and poor patient selection.

A historical review of the same outbreak describes intravenous fluid, oral salt-and-water treatment and chemical analysis of body fluids as three advances that appeared briefly and then lapsed. It reports that the modern era of rehydration for cholera and dehydrating diarrhea developed slowly from the period after World War II through the 1970s. These sources describe the hospital use of fluids and say nothing about elective services.

The growth of drip bars and mobile services

A 2016 newspaper report from Las Vegas describes a Los Angeles-based company running a mobile unit on the Strip that offered intravenous vitamin infusions to people with hangovers and nausea, and lists several local businesses offering infusions on site or at homes and hotel rooms. The report notes that the company said some of its bags were similar to those used in emergency rooms, and that the unit did not provide emergency medical services.

A 2025 study of United States facilities states that the number of IV hydration spas has grown over the past decade. The sources reviewed do not date the first drip bar, do not give a count of services before 2016, and do not document the growth after 2020 in numbers, so this page does not state an origin date or a market size.

Names in use

The services appear under several names. The 2025 facility study uses the term IV hydration spas, while a Polish survey of health professionals uses intravenous nutrient therapies and also lists the keywords vitamin drips, nutrient cocktails and drip bars. A German medical society uses the term drip bars. Newspaper coverage speaks of IV vitamin therapy. These labels overlap and have no shared formal definition in the sources reviewed.

Elective hydration compared with prescribed IV fluids

In hospitals, an international fluid academy summary advises that intravenous fluid be treated like any other pharmacological prescription, with three main indications: resuscitation, replacement and maintenance. Elective services differ in setting and purpose. A case report on a medical spa infusion states that hospital fluids are typically guided by laboratory values and clinical status, whereas outpatient services may lack routine screening and monitoring. This page is a member of the Machipedia family page IV Therapy, which covers the wider field; related pages include Myers' Cocktail, High-Dose Intravenous Vitamin C, Intravenous Glutathione, NAD+ IV Therapy and Nutritional Therapy.

Settings and staffing

Services are offered at drip bars, medical spas, concierge practices and by mobile units that travel to homes and hotels. The 2016 Las Vegas report says one company employed nurses who consulted with clients and gave the infusions, with physician assistants and doctors on staff. The 2025 study found that staffing varied between facilities, and that in a secret shopper sample of 87 facilities, 24 (27.6 percent) required a consultation with a licensed medical professional before treatment.

What a visit is described as involving

In general terms, sources describe a short assessment or consultation, the placement of a small catheter in a peripheral vein, and an infusion of a fluid, commonly saline with added vitamins, minerals or other products, while the client sits or reclines. A review of 255 facility websites found that all offered IV hydration therapy, most often combined with magnesium (57.3 percent) and glutathione (53.7 percent), and that vitamin injections were also offered by 63.5 percent. This page gives no volumes, rates or formulas.

Uses promoted by providers

Providers promote the infusions for hangovers, nausea, headache, colds, energy, immunity and recovery. The 2016 Las Vegas report records these claims, and the 2025 study found that every one of the 255 websites reviewed included claims of beneficial uses. Only 2 websites (0.8 percent) cited sources for them. In the secret shopper sample, 75 of 87 facilities (86.2 percent) recommended specific therapies for a presented headache and cold symptoms.

How professionals see the justification

A survey of 188 health professionals in Poland, conducted from April 2019 to March 2020, found that the most commonly named situation in which such infusions would be justified was a diagnosed nutrient deficiency (37.8 percent of respondents). Libido problems (1.1 percent) and speeding up metabolism (2.1 percent) were rarely named, and 25.5 percent said there was no good rationale for the infusions at all. The survey was a preliminary report, not a population study.

Intravenous versus oral rehydration after exercise

Small randomized studies compare intravenous and oral fluids in exercise settings. In a crossover study of 12 men dehydrated by heat and exercise, a combined intravenous and oral approach lowered body temperature more than oral or free drinking when each was compared with no fluid, and the authors stated that studies of clinical implications were needed. In a related study of 10 men, adding intravenous fluid was not superior to oral rehydration for the appearance of fluid in sweat.

A trial of 66 marathon runners compared an intravenous infusion with a placebo infusion and found no significant effect on total recovery, pain, stiffness, appetite, sleep or fatigue; recovery took 9.2 days in the placebo group and 10.2 days in the infusion group. These were healthy young or middle-aged athletes, so the results do not describe the general public.

Collapsed runners and a clinical comparator

In a randomized trial of 133 collapsed ultramarathon runners treated in a medical tent, intravenous fluid produced larger but nonsignificant reductions in blood sodium than oral fluid, and 45 percent of runners assigned to oral fluid could not tolerate it. The authors suggested intravenous fluid may best benefit hypernatremic collapsed runners who cannot tolerate oral fluid. This is a medical-tent population and must not be carried over to elective drips.

Hangover and wellness claims

A 2005 systematic review of randomized trials of interventions for hangover concluded that no compelling evidence existed for any conventional or complementary intervention, and a 2022 review of placebo-controlled trials (21 studies, 386 participants) rated all efficacy evidence as very low quality. The abstracts of both reviews do not list an intravenous fluid trial, and the full texts were not read for this page.

Searches of PubMed for controlled trials of intravenous fluid for hangover, for alcohol intoxication in emergency departments and for elective vitamin drips in healthy adults returned no trials. A physician quoted in the 2016 report said there were no studies showing that such treatments work well. The sources reviewed contain no controlled trial of wellness benefit in people without a deficiency.

Reported adverse events

A 2025 case report describes an elderly woman with a single kidney who received a vitamin infusion in sterile water at a medical spa, followed by saline with high-dose vitamin C. She developed fluid in the lungs and a cardiac arrest, then kidney failure needing dialysis and a bowel perforation needing surgery. The authors cite suspected red cell breakdown, the vitamin C and reduced kidney reserve as contributors, and call it a rare and preventable case. One case cannot show how often such events occur.

A German internal medicine society, as reported in the medical press in September 2024, named infection at the insertion site, allergic reactions and circulatory problems from rapid fluid intake, and warned that people with kidney damage in particular should avoid such lifestyle infusions. No frequency data for these events in drip-bar clients were found in the sources reviewed.

What professional bodies state

The German society's chair described the infusions as lacking demonstrated health benefit and the society advised against receiving them without medical advice and supervision, adding that anyone feeling weak or unwell should first consult a primary care doctor. In the Polish survey, 95.2 percent of professionals recognized health risks, the main concerns being missing information on health status and contraindications (84 percent), overdose and interactions (77.1 percent) and hypersensitivity (75.5 percent).

Fluid overload is also a recognized harm in hospital practice. The international fluid academy summary notes growing interest in the potential harms of fluid overloading and advises matching fluid to need. The sources reviewed include no statement from the American Society of Anesthesiologists, nursing or emergency medicine bodies on elective IV hydration.

Sport and suitability

A sports institute page summarizing the World Anti-Doping Agency prohibited list states that intravenous infusions are restricted for athletes subject to anti-doping rules, with exceptions for hospital treatment and clinical investigation, and that in 2008 infusions were prohibited outright. This is a sporting rule, not a health finding, and the page gives two different thresholds, so athletes should check the current list itself.

Because the sources describe harms linked to kidney disease, fluid status and the contents of the infusion, anyone considering such a service should discuss it with a doctor who knows their health history. This page is information only and does not replace necessary medical care.
