What's in a Hangover IV? (And Does It Work?)
The exact ingredients in a hangover drip, why each one helps, and how fast you'll feel better.
A hangover IV combines about a liter of saline fluid with electrolytes, B vitamins, and usually optional anti-nausea (like ondansetron) and anti-inflammatory (like ketorolac) medications. The fluids and electrolytes fix the dehydration behind most hangover symptoms, while the medications target nausea and headache — most people feel noticeably better within 30–45 minutes.

The ingredients, and what each does
Saline fluids and electrolytes do the heavy lifting: alcohol is a diuretic, and the dehydration it causes drives the headache, fatigue, and brain fog. B vitamins (especially B12 and B-complex) support energy metabolism that heavy drinking depletes.
Most providers offer add-on medications: an anti-nausea drug to settle your stomach and an anti-inflammatory to take the edge off the headache. Some add antioxidants like glutathione.
How fast it works
Because it's delivered intravenously, relief is fast — typically noticeable within the 30–45 minute session and continuing to build afterward. It treats symptoms rather than curing the hangover, but for a rough morning before an important day, that distinction rarely matters.
