A hangover IV drip puts fluid, and often vitamins or electrolytes, straight into a vein, so it rehydrates you faster than drinking, but we found no randomized trial showing it eases hangovers better than oral fluids and rest, and it adds cost and small risks. Most hangovers involve only mild dehydration, which water fixes for free. Cleveland Clinic puts a basic IV session at more than $150.
Key takeaways
- Research hasn't found a correlation between the extent of electrolyte disruption and hangover severity, or that added electrolytes change severity, according to NIAAA.1
- In our PubMed search of October 9, 2026, we found no randomized trial of IV fluids or vitamin drips for hangover; systematic reviews have found only very low-quality evidence for any hangover remedy.2
- Cleveland Clinic says a basic IV vitamin session typically costs more than $150 and specialized drips can run up to $1,000.3
- Reported risks include infection or bruising at the needle site, vitamin toxicity, a blood-vessel blockage and drug interactions; a 2025 case report described Stevens-Johnson syndrome after IV glutathione and vitamins.3, 4
What's in a hangover IV?
Usually IV fluid with electrolytes, plus some mix of vitamins, minerals and antioxidants. NIAAA notes that some people turn to IV treatments to correct electrolyte imbalance from alcohol's extra urine output.1
Cleveland Clinic describes IV vitamin therapy as "a liquid mixture of vitamins, minerals and antioxidants," with menus built around B vitamins, vitamin C, magnesium, zinc, calcium and electrolytes.3 Formulas differ from clinic to clinic, so ask exactly what's in the bag, including whether any prescription medicine is added.
| Ingredient | The pitch | What the evidence shows |
|---|---|---|
| IV fluid with electrolytes | Fast rehydration | Dehydration markers and electrolytes don't track hangover severity, and balance usually recovers on its own once alcohol wears off.5, 1 |
| B vitamins (such as thiamin) | "Replace what alcohol depletes" | Thiamin deficiency affects up to 80% of people with chronic alcoholism; that's a long-term problem, not a one-night one.6 No hangover trial found. |
| Magnesium | Aches, headache, "recovery" | Deficiency is common in chronic heavy drinking.7 No hangover trial found. |
| Vitamin C, glutathione and other antioxidants | "Antioxidant support" | No hangover trial found. A 2025 case report linked IV glutathione and vitamins to Stevens-Johnson syndrome, a severe skin reaction.4 |
What does the research say about hangover IV drips?
Almost nothing, because the trials haven't been done. As of October 2026, we found no randomized trial of IV fluids or vitamin drips for hangover.
A 2022 systematic review of 21 placebo-controlled hangover trials found "only very low quality evidence" for any remedy tested.2
There's also a mismatch between what a drip does and what drives a hangover. Fluids correct dehydration, but dehydration and hangover severity are only weakly linked.5 The bigger factors are how much you drank, broken sleep and inflammation, and saline doesn't change those. An hour lying down helps, but so does lying down at home.
Regulators have noticed. In 2018, in its first action targeting "IV cocktail" therapy, the FTC charged iV Bars with claiming its drips could treat serious diseases and were scientifically proven, and announced a proposed settlement barring such claims without competent and reliable scientific evidence.8 Pills sold as hangover fixes face the same evidence gap; see do hangover pills work?
Risks, and who should avoid them
For most healthy adults the risks are small, but they're real, and they're risks you don't take with a glass of water.
Cleveland Clinic lists infection or bruising at the needle site, vitamin toxicity if doses are too high, an embolism (blockage) in a blood vessel from the injection, and interactions with medicines you take.3 Rare severe reactions happen too, such as the Stevens-Johnson syndrome case reported after IV glutathione and vitamins.4
Cleveland Clinic advises avoiding IV vitamin therapy if you're being treated for heart disease, high blood pressure or kidney disease, or if you're pregnant.3 It also describes hydration clinics and spas as "largely unregulated," reports that FDA has warned about the safety of IV mixtures coming out of them, and suggests asking how drips are formulated and whether a licensed medical director oversees them.
If you're still very drunk, vomiting repeatedly or confused, you need medical assessment, not a spa appointment: those can be signs of alcohol poisoning.9
Cost vs. benefit
A basic IV session typically costs more than $150, and specialized drips can run up to $1,000, according to Cleveland Clinic.3 That buys you fluid, an hour of rest and vitamins that, for an occasional drinker, there's no evidence you ran short of overnight.
A liter of ready-made oral electrolyte solution costs around $5, and tap water costs almost nothing; our electrolyte drink comparison lists label prices checked in October 2026. For a realistic morning plan, see how to get rid of a hangover fast.
Oral rehydration: the cheaper alternative
If you've lost real fluid, by vomiting, diarrhea or sweating, an oral rehydration drink does the same basic job as an IV for most people, as long as you can keep it down.
WHO's oral rehydration solution, sodium, potassium and glucose in water, is the standard treatment for dehydration from diarrhea.10 CDC says severe fluid loss is best replaced with oral rehydration solution, and in mild cases any preferred liquid, including sports drinks, will do.11 Sip slowly if you're queasy. More in electrolytes for a hangover and hangover nausea.
When IV fluids are medically necessary
When you can't keep fluids down or show signs of severe dehydration, IV fluids are real medicine, given in urgent care or an emergency department.
MedlinePlus lists signs of severe dehydration, including little or no urine, dizziness, a rapid heartbeat and confusion, and notes severe cases may need hospital IV fluids.12 After drinking, confusion, seizures, slow or irregular breathing or being hard to wake mean alcohol poisoning: call 911.9 See the signs of alcohol poisoning.
What we don't know yet
- Whether IV fluids or vitamin drips change hangover severity at all compared with drinking fluids. We found no trial testing it.
- How often side effects happen at hydration clinics; we found case reports, not systematic data.
What we do know: current US guidance is "Consume less alcohol for better overall health," and pregnant women, people in recovery and people on interacting medicines shouldn't drink at all.13 Hangovers impair coordination, so don't drive yourself there.1
Frequently asked questions
Do IV drips actually cure hangovers?
No. There's no proven hangover cure, and we found no randomized trial showing IV drips relieve hangovers better than drinking fluids and resting. Drips do rehydrate you quickly, but dehydration is only weakly linked to how bad a hangover feels.
How much does a hangover IV cost?
Cleveland Clinic says a basic IV session typically costs more than $150, and specialized drips can run up to $1,000. Prices vary by clinic and city. A liter of ready-made oral electrolyte solution costs around $5.
Is an IV better than an oral rehydration drink?
It's faster, but for most hangovers not meaningfully better. If you can keep fluids down, an oral rehydration drink or water replaces what you've lost for a fraction of the cost. If you can't, you need medical care.
Are hangover IVs safe?
For most healthy adults the risks are small but real: infection or bruising, vitamin toxicity, blood-vessel blockage, drug interactions and rare severe reactions. Cleveland Clinic advises avoiding IV vitamin therapy with heart disease, high blood pressure, kidney disease or pregnancy. Ask who oversees the clinic and what's in the bag.
