IV Drips Explained
IV Drips Explained: What They Actually Treat, What the Wellness Version Claims, and How to Tell the Difference
If you live in New York City, you have seen them: storefront “drip bars,” pop-up lounges, and concierge services promising that a bag of fluid dripped into your arm will cure your hangover, “boost” your immune system, reverse aging, brighten your skin, or restore your energy. The IV wellness business is enormous and growing fast. The broader medical-spa industry earned about $15 billion in 2022, with roughly 10% of that coming from IV hydration spas, and the number of medical spas in the US jumped from 5,431 in 2018 to 8,841 in 2022 (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025.)
Here is the honest, evidence-based picture — starting with the part most drip-bar marketing leaves out: an IV is a real medical procedure, and the specific “wellness” ingredients being sold have very little, and sometimes zero, evidence behind them.
First, the part that is true: IV fluids are real medicine
An intravenous line delivers fluid and medication directly into your bloodstream. This is genuinely lifesaving in the right setting: severe dehydration when a person cannot keep fluids down, shock, major blood loss, serious infections, diabetic emergencies, chemotherapy, and situations where the gut cannot absorb what the body needs. In those cases, isotonic IV fluids such as normal saline and lactated Ringer’s are the correct, standard-of-care treatment (Shane AL, Mody RK, Crump JA, et al. 2017 Infectious Diseases Society of America Clinical Practice Guidelines for the Diagnosis and Management of Infectious Diarrhea. Clin Infect Dis. 2017.)
The wellness industry borrows the credibility of this real medicine and attaches it to claims the science does not support. Understanding what your body actually does with each infusion is the fastest way to see the difference.
“Hydration” and hangover drips: your kidneys usually do this for free
The pitch is that IV fluids rehydrate you faster and better than drinking. For a healthy person with a hangover or ordinary tiredness, this is mostly marketing. When you drink fluids, your intestine absorbs water efficiently, and your kidneys fine-tune the balance. When you receive more salt water than you need, your kidneys simply excrete the excess in your urine within hours — you are, in effect, paying a premium to make expensive urine.
The medical evidence is clear that for mild-to-moderate dehydration, drinking (oral rehydration) works as well as an IV. A meta-analysis of 17 randomized trials found no meaningful difference between oral rehydration and IV fluids in the ability to rehydrate, and the IV group had more complications such as vein inflammation (phlebitis). IV fluids are reserved for severe dehydration, shock, altered mental status, or an inability to tolerate fluids by mouth — not for a rough morning after (Shane AL, Mody RK, Crump JA, et al. 2017 Infectious Diseases Society of America Clinical Practice Guidelines for the Diagnosis and Management of Infectious Diarrhea. Clin Infect Dis. 2017).

NAD+ drips: fashionable, expensive, and not tested for what they claim
NAD+ (nicotinamide adenine dinucleotide) is a molecule your cells use for energy and repair, and its levels do decline with age — which is why “NAD+ IV therapy” is marketed for anti-aging, energy, and mental clarity. The biology is genuinely interesting. The clinical evidence for the drip is not there.
A 2026 PRISMA-guided systematic review examined 113 studies of NAD+ and its precursors. Its key finding for anyone considering a drip: there were no completed outcome trials evaluating intravenous NAD+ for anti-aging or wellness at all. Even for oral NAD+ precursors, the effects on real health outcomes were “heterogeneous and often null” (Gallagher C, Emmanuel OO. NAD+ Supplementation for Anti-Aging and Wellness: A PRISMA-guided Systematic Review of Preclinical and Clinical Evidence. Ageing Res Rev. 2026). A major endocrinology review reached the same conclusion — early human findings are promising enough to justify large trials, but those trials have not yet shown that raising NAD+ prevents or treats age-related disease (Bhasin S, Seals D, Migaud M, Musi N, Baur JA. Nicotinamide Adenine Dinucleotide in Aging Biology: Potential Applications and Many Unknowns. Endocr Rev. 2023). In plain terms: you are paying for a treatment whose central promise has never been tested in a proper trial. NAD+ infusions also commonly cause nausea, cramping, flushing, and chest discomfort if run too fast.

Glutathione drips: for “skin brightening” and detox — and here the concern is safety, not just cost
Glutathione is an antioxidant your body makes on its own. IV glutathione is marketed heavily for skin lightening, “detox,” and anti-aging. The evidence is weak and the safety signal is real.
A 2025 systematic review found only a single placebo-controlled study of IV glutathione for skin lightening, and its result was not statistically significant. The review’s conclusion was blunt: IV glutathione is “contraindicated due to lack of efficacy and side effects” (Sarkar R, Yadav V, Yadav T, P J, Mandal I. Glutathione as a Skin-Lightening Agent and in Melasma: A Systematic Review. Int J Dermatol. 2025). A 2026 dermatology review documented that intravenous glutathione has been associated with serious harms including anaphylaxis, Stevens-Johnson syndrome (a life-threatening skin reaction), and kidney dysfunction, and concluded that these safety concerns “preclude its consideration as a routine anti-aging therapy” (Vipulaguna N, Abdulkader F, Patin E, et al. Cutaneous Aging in Skin of Color: A Narrative Review. Am J Clin Dermatol. 2026).

“Immunity” and vitamin drips (the “Myers cocktail” family)
These bags typically combine vitamin C, B vitamins, and minerals like magnesium, and are sold to “boost immunity” or energy. For a person who is not deficient, there is no good evidence that flooding the bloodstream with water-soluble vitamins improves immune function or energy — your body excretes what it does not need. The government’s own analysis of the industry found that spas most commonly claimed to boost energy, support immunity, and slow aging, yet very few provided any evidence to support these claims (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025).
The add-ons that deserve the most caution: compounded prescription drugs
Increasingly, drip menus include prescription medications such as GLP-1 weight-loss agents, the anti-inflammatory ketorolac, the anti-nausea drug ondansetron, and diphenhydramine (Benadryl). At least one-quarter of spas offer such compounded pharmaceutical products (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025.). These are real drugs with real interactions and side effects — which is exactly why they belong with a clinician who knows your medical history, not on a walk-in menu.
The regulation gap: why “it’s medical-grade” doesn’t mean “it’s FDA-approved”
This is the single most important thing to understand. Most IV spas operate as independent compounding pharmacies. Under Section 503A of federal law, they are exempt from FDA premarket approval and from the manufacturing and labeling standards that apply to ordinary prescription drugs (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025.). So “medical-grade” and “compounded just for you” are not the same as “FDA-approved and quality-tested.”
Why this matters for your safety: compounded sterile products have a documented history of contamination. A 2012 outbreak traced to a Massachusetts compounding pharmacy caused more than 750 fungal infections and more than 60 deaths, prompting new federal law (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025.). The FDA has since overseen more than 140 recalls of compounded drugs and, during inspections, documented conditions including visible mold and dead insects in supposedly sterile compounding areas; it has also received reports of deaths from improperly compounded infusions (Woodcock J, Dohm J. Toward Better-Quality Compounded Drugs — An Update from the FDA. N Engl J Med. 2017.). In 2021, the FDA warned states after a patient developed septic shock following IV infusion therapy at a compounding clinic (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025.). Multiple contamination outbreaks over the years have been linked to compounding pharmacies, which is why patient-safety experts have long called for stronger oversight (Guharoy R, Noviasky J, Haydar Z, Fakih MG, Hartman C. Compounding Pharmacy Conundrum. Chest. 2013.).

What actually happens at the point of sale
When investigators posed as customers calling 87 IV spas nationwide with cold and headache symptoms, the findings were revealing:
- Only 27.6% said a consultation with a licensed medical professional was required before treatment.
- Only 24.4% mentioned any risks of IV therapy when asked, most commonly bruising, infection, or bleeding.
- 86.2% recommended a specific drip for the symptoms described, essentially over the phone.
- None accepted health insurance; the median out-of-pocket cost was $179 per single treatment (Sivakumar A, Forman HP, Wang I, Lurie P, Ross JS. State Policies and Facility Practices of IV Hydration Spas in the US. JAMA Intern Med. 2025).
No insurer covers these services because there is no medical indication — which tells you how the medical system already judges them.
5 questions to ask before you let anyone put a needle in your arm
1. What is the specific medical reason I need this? “Wellness,” “boosting,” and “detox” are not medical indications. Real IVs treat identified problems.
2. Who is prescribing and supervising, and will a licensed clinician review my history first? If no clinician evaluates you, that is a red flag.
3. What exactly is in the bag, and is it a compounded product? Ask whether the ingredients are FDA-approved for this use, and where and how they were compounded.
4. What are the risks, and what happens if I have a reaction? A legitimate provider discusses infection, allergic reaction, vein injury, and electrolyte risks up front.
5. Is there published evidence this works — and would my doctor recommend it? If the only “evidence” is testimonials, treat it as advertising.

The bottom line
IV therapy is powerful, legitimate medicine when there is a genuine medical need — severe dehydration, serious illness, or a condition that prevents you from absorbing what your body requires. But the trendy “wellness” versions — NAD+, glutathione, immunity and vitamin drips, and hangover cures — are largely unproven, are not FDA-approved for these uses, carry real (if uncommon) risks of infection and serious reactions, and cost money that buys little benefit for a healthy person. Before booking any infusion, talk with a licensed clinician who knows your history. The best “boost” for most healthy people remains unglamorous and free: water, sleep, food, and time.

If you have a genuine medical concern, see a licensed clinician. Questions about whether an infusion is appropriate for you are worth asking before, not after, you book one.
