A hangover IV looks like one thing — a clear bag dripping into your arm — but it’s a deliberate cocktail. Each ingredient targets a specific part of what makes you feel terrible. Here’s every component of a properly built hangover drip, why it’s in there, and which add-ons are worth paying for.
The base: isotonic fluid (1 liter, normal saline)
This is the most important ingredient. Alcohol is a diuretic — you lose 1–2 mL of urine for every 1 mL of alcohol consumed. By morning, you’re 1–2 liters down. Drinking water is slow because your gut is irritated and your hydration markers correct over hours. A liter of saline restores plasma volume in 30–45 minutes. If you take nothing else out of this article: it’s the saline that does most of the heavy lifting.
B-complex + B12
Alcohol depletes B vitamins, particularly B1 (thiamine), B6 and B12. Low B-complex levels show up as fatigue, brain fog, and the “everything is too bright” feeling. A standard hangover IV includes:
- B1 (thiamine) — clinically important for heavy drinkers; protects against more serious neurological depletion.
- B5 (pantothenic acid) — supports adrenal function on a stressed morning.
- B6 (pyridoxine) — supports neurotransmitter synthesis.
- B12 (methylcobalamin or cyanocobalamin) — the famous “energy” B vitamin. Doesn’t manufacture energy out of thin air, but it does correct the mental fog reliably.
Magnesium sulfate
Drinking depletes magnesium and contributes to the muscle aches, headache, and irritability of a hangover. 1–2 grams of magnesium sulfate added to the bag handles all three. Magnesium is also why people sleep better the night after an IV drip — it’s mildly calming to the nervous system.
Anti-nausea agent (clinically appropriate)
Ondansetron (Zofran) is the most common antiemetic added to a hangover IV when the patient is actively nauseated. It works within 15 minutes. Metoclopramide is an alternative. Both have well-established efficacy. Note: this is a prescription medication, added at the discretion of our medical team after a brief intake.
Anti-inflammatory (NSAID, clinically appropriate)
Ketorolac (Toradol) is the go-to IV NSAID for headache relief. It’s stronger and faster than oral ibuprofen and bypasses an already-irritated stomach. Skipped for patients with kidney concerns, ulcer history, or pregnancy.
The optional add-ons that actually matter
Glutathione
The master antioxidant. Alcohol metabolism produces oxidative stress, and glutathione gets depleted in the process. A 1–2 g push of glutathione at the end of the bag is the most-requested add-on for a reason — it helps with the “wrung out” feeling and supports liver clearance.
Vitamin C (5 g)
Additional antioxidant support and a small immune kicker, useful if you’re already coming off a long week of travel and drinking.
Taurine
Found in energy drinks for a reason. Modulates GABA signaling and may dampen the residual jitteriness some people feel hours after the alcohol clears.
Zinc
Helps with immune function and is mildly depleted by chronic drinking; useful as a once-or-twice add-on, not necessary every time.
What’s NOT in a proper hangover IV (and shouldn’t be)
- Caffeine. Sometimes pitched as an “energy” add-on; we don’t add it. You can drink coffee. IV caffeine isn’t the right tool.
- “Detox” mystery ingredients. Your liver does the detoxing. Anything labeled “detox” in a bag without a named molecule is marketing.
- High-dose vitamin A or iron. Both are inappropriate in this context.
How our Cabo hangover IV is built
Our most-booked hangover stack is the Recovery / Glow-Up drip — 1 L saline + B-complex + B12 + magnesium, with ondansetron and ketorolac available at the medical team’s discretion, and glutathione + vitamin C as the most-requested add-ons. The classic Myers’ Cocktail is a milder version. For straight rehydration without the extras, pure Hydration is the option.

What is the most important ingredient in a hangover IV?
The 1 L of normal saline. It does most of the work — rapid rehydration is the mechanism that resolves most hangover symptoms.
What does B12 do in a hangover IV?
B12 corrects the mental fog and supports energy production. Alcohol depletes B vitamins; replacing them addresses the foggy depleted feeling reliably.
Is ondansetron in every hangover IV?
No. It’s added when nausea is present, at the medical team’s discretion. It’s a prescription medication, not a default ingredient.
Should I add glutathione to a hangover IV?
It is the most-requested add-on for good reason — it helps with oxidative stress and the wrung-out feeling. Worth it for moderate-to-heavy hangovers.
How long does the IV take to feel?
Most people feel substantially better within 30 minutes — saline and magnesium work fastest. Full effect by the end of the bag (45 minutes).
Educational content. Medications and dosing are at the discretion of our medical team after intake. Patients with kidney, heart, ulcer or pregnancy considerations should disclose all conditions; some add-ons will not be appropriate.
