Banana Bag IV: What It Is, Ingredients, and Uses
A banana bag IV is a hospital infusion of thiamine, folic acid, a multivitamin, and magnesium mixed into a liter of saline or dextrose fluid. The multivitamin turns the bag bright yellow, which is where the nickname comes from. Hospitals use it mainly for patients with alcohol-related malnutrition who are at risk of vitamin deficiencies.
There is no banana in it, and it was never designed as a hangover drip. That surprises a lot of people who see "banana bag" on a wellness menu or hear it from a friend who works in an ER.
This guide explains what goes into a banana bag, why hospitals use it, how it compares to the wellness IVs you can book at home, and which RevivaGo treatment is the closest honest match for what you actually need. It was reviewed by our medical director for readers in Queen Creek, Gilbert, San Tan Valley, and Mesa.
This article is general education, not medical advice. If you or someone you know is in alcohol withdrawal, call 911 or go to the ER.
What is a banana bag?
A banana bag is a vitamin and electrolyte infusion that emergency departments and ICUs give to patients who drink heavily or have poor nutrition. Its job is to replace nutrients that chronic alcohol use drains, especially thiamine (vitamin B1), before those gaps cause nerve or brain damage.
Nurses and doctors call it a "banana bag" because of its color. The term is slang, not a formal drug name, so you won't find it on a pharmacy label. Each hospital writes its own order, which means the exact recipe varies from one place to the next.
Banana bag ingredients
Most banana bag recipes share the same core ingredients. Doses below are typical of hospital protocols described in clinical literature, and your local hospital's version may differ.
| Ingredient | Typical hospital amount | Why it's included |
|---|---|---|
| Base fluid | 1 liter of normal saline or 5% dextrose (D5) | Rehydration and a carrier for the vitamins |
| Thiamine (B1) | 100 mg | Helps prevent Wernicke's encephalopathy |
| Folic acid (B9) | 1 mg | Replaces folate, often low with heavy drinking |
| Multivitamin infusion (MVI) | 1 vial (10 mL) | Broad vitamin coverage; gives the yellow color |
| Magnesium sulfate | 1 to 2 grams | Replaces magnesium lost through alcohol use |
Why is a banana bag yellow?
The yellow comes from riboflavin (vitamin B2) in the multivitamin vial. Riboflavin is naturally bright yellow-orange, and even a small amount tints a full liter of clear fluid. The same vitamin turns urine bright yellow after you take a B complex supplement.
Saline or dextrose?
Some hospitals mix the vitamins into normal saline, and others use dextrose, a sugar solution. In patients at risk of thiamine deficiency, clinicians usually give thiamine before or alongside sugar, since glucose can use up the body's remaining thiamine stores. If you want to understand the fluid options in more depth, our guide to lactated Ringer's vs normal saline covers the differences.
Why hospitals use a banana bag
The main reason is thiamine. Long-term heavy drinking reduces how much thiamine you absorb and store. According to the NIH Office of Dietary Supplements, thiamine deficiency is common in people with alcohol use disorder, with some studies finding it in as many as 80% of them.
Severe thiamine deficiency can cause Wernicke's encephalopathy, a medical emergency that affects the brain. StatPearls, the NIH-hosted clinical reference, describes its classic signs as confusion, trouble with balance and walking, and abnormal eye movements. StatPearls also notes that only a minority of patients show all three signs at once, so clinicians treat risk early instead of waiting for the full picture. Untreated, it can progress to Korsakoff syndrome, which causes lasting memory loss.
Folate and magnesium are also often low in people who drink heavily. A banana bag tops up all of these in one bag while the patient is already getting fluids.
What the research says about banana bags
The banana bag is a habit more than a precise prescription. A 2016 review in Critical Care Medicine titled "Unpeeling the Evidence for the Banana Bag" found that the standard 100 mg thiamine dose may be too low to treat suspected Wernicke's, and that many patients may need higher, repeated doses. The authors also questioned whether every patient needs the multivitamin.
In practice, that means hospitals increasingly tailor the order to each patient. It also means the banana bag is a medical treatment for a specific risk, not a general wellness product.
Is a banana bag good for a hangover?
A banana bag isn't designed for an ordinary hangover. It was built for nutritional deficiency that develops over months or years of heavy drinking, not for one rough morning after a wedding or a night out in downtown Gilbert.
What a typical hangover needs is simpler: fluids to correct dehydration, and sometimes relief from nausea and headache. Thiamine and folate don't hurt, but they don't target the things that make you feel awful the next day. Our hangover treatment guide breaks down what the evidence supports and what it doesn't.
When to skip IV wellness and go to the ER: shaking, sweating, a racing heart, hallucinations, or a seizure after cutting back on alcohol can be signs of alcohol withdrawal. Confusion, unsteady walking, or unusual eye movements in someone who drinks heavily can point to Wernicke's. Both need hospital care, not a mobile IV.
Banana bag vs Myers' Cocktail vs hydration IVs
A banana bag and a Myers' Cocktail are often confused because both are vitamin IVs. They were built for different people. The banana bag corrects deficiency in hospital patients. The Myers' Cocktail is a wellness drip for generally healthy adults who want hydration, energy, and immune support.
The table below compares a hospital banana bag with three treatments on our menu. RevivaGo ingredients and prices come from our current booking system.
| Banana bag (hospital) | Hydration Boost | Myers' Cocktail | Hangover Relief | |
|---|---|---|---|---|
| Main purpose | Replace vitamins in malnourished or heavy-drinking patients | Rapid rehydration | Energy, immune support, and overall wellness | Next-day hangover symptoms |
| What's in it | Saline or D5, thiamine, folic acid, multivitamin, magnesium | 1 liter of fluids, electrolytes, B vitamins | B vitamins, glutathione, vitamin C, magnesium | Fluids plus nausea relief, customized to your symptoms |
| Where you get it | ER, hospital floor, or ICU | At home, office, or hotel | At home, office, or hotel | At home, office, or hotel |
| Ordered by | Hospital physician | RevivaGo medical team after intake | RevivaGo medical team after intake | RevivaGo medical team after intake |
| RevivaGo price | Not offered | $149 | $199 | $229 |
Bottom line: if you are healthy and want hydration and vitamins, a Myers' Cocktail is the closest wellness cousin to a banana bag. If you are hungover, Hangover Relief targets the symptoms you actually feel. If you suspect a real nutritional deficiency or alcohol withdrawal, that belongs with a hospital or your doctor.
To be clear, RevivaGo does not sell a product called a "banana bag," and we won't pretend one of our drips is a hospital protocol. You can read more about the Myers' blend in our Myers' Cocktail benefits guide or on the Myers' Cocktail IV therapy page.
How to choose the right IV at home
If you came here searching for a banana bag IV near you, these steps can help you land on the right option.
- Rule out an emergency. Withdrawal symptoms, confusion, fainting, or chest pain mean 911 or the ER. Our guide to the signs you need IV fluids sorts symptoms by severity.
- Name your main goal. Thirsty and drained from the Arizona heat? Start with hydration. Hungover and queasy? Look at hangover care. Run down and want a vitamin boost? Consider the Myers' Cocktail.
- Check the ingredients, not the nickname. Ask any provider what is actually in the bag and who ordered it. Names like "banana bag" can mean different things at different clinics.
- Complete the medical intake. At RevivaGo, a short health screening is reviewed under physician oversight before every treatment, so the drip fits your history and medications.
- Book and rest. A licensed RN, NP, or paramedic comes to you, and most drips take 30 to 45 minutes.

Frequently asked questions
What is in a banana bag IV?
A banana bag usually contains 1 liter of normal saline or dextrose with 100 mg of thiamine, 1 mg of folic acid, a vial of multivitamin infusion, and 1 to 2 grams of magnesium sulfate. Hospitals write their own orders, so amounts vary. The multivitamin gives the bag its yellow color.
Why is it called a banana bag?
It is called a banana bag because the fluid turns bright yellow, like a banana peel. The color comes from riboflavin (vitamin B2) in the multivitamin added to the bag. There is no banana or potassium from bananas in it. The name is hospital slang, not an official drug name.
Is a banana bag the same as a Myers' Cocktail?
No. A banana bag is a hospital treatment that focuses on thiamine, folate, and magnesium for patients at risk of deficiency, often from heavy alcohol use. A Myers' Cocktail is a wellness IV with B vitamins, vitamin C, and magnesium for generally healthy adults. Both include vitamins and fluids, but they serve different purposes.
Can I get a banana bag for a hangover?
A banana bag isn't meant for a typical hangover, and most hangover symptoms come from dehydration, poor sleep, and an irritated stomach rather than vitamin deficiency. A hydration or hangover IV that focuses on fluids and nausea relief is usually a better fit. Any IV should follow a health screening by a licensed provider.
Where can I get a banana bag IV near me?
True banana bags are given in hospitals and emergency departments, usually to patients being treated for alcohol-related problems or malnutrition. Some IV clinics use the name for their own vitamin blend, so ask what is in it. In the East Valley, RevivaGo offers hydration, Myers' Cocktail, and hangover IVs at home, but not a hospital banana bag.
Is a banana bag IV safe?
In a hospital, a banana bag is a routine, low-risk infusion when ordered for the right patient. Vitamins and magnesium still need medical oversight, especially for people with kidney disease, heart conditions, or certain medications. That's why any IV, at home or in a hospital, should start with a health screening by a licensed clinician.
The right drip for the right reason
A banana bag IV is a smart tool in the hospital, built to protect people with alcohol-related malnutrition from serious vitamin deficiencies. For most healthy adults who are dehydrated, run down, or hungover, a wellness IV that matches your symptoms makes more sense than chasing a hospital nickname.
If you're in Queen Creek, Gilbert, San Tan Valley, or Mesa and want hydration or vitamin support instead of a banana bag IV and a hospital waiting room, book a visit and our licensed team will come to you, often the same day.
