Do Hangover IV Drips Actually Work? An Honest Answer

Do hangover IV drips work? Partly. The fluids can help you rehydrate quickly, especially if you’ve been vomiting and can’t keep water down, and many people feel better within a few hours. But there’s little research on hangover drips themselves, the role of the added vitamins is unproven, and no drip makes alcohol leave your body faster.

We give hangover drips every week on Koh Phangan, so you might expect us to oversell them. We’d rather you knew exactly what a drip can and can’t do, then decide for yourself.

What is a hangover IV?

A hangover IV is a bag of fluid given through a small cannula in a vein, usually in your arm or hand. The base is almost always electrolyte fluid: water with salts such as sodium and potassium. Many providers add vitamins, and some add medicines for nausea or headache.

Our Hangover Recovery drip contains:

• 1 litre of electrolyte fluids to replace water and salts
• B-complex and vitamin C, which are common additions to hangover drips
• Anti-nausea medicine and pain relief, given only if the nurse’s health check shows they’re suitable

The drip runs for 45–60 minutes, and a licensed nurse stays with you the whole time.

What the fluids reliably do

Alcohol makes you pass more urine, and a night of dancing in the heat adds sweat on top. Add vomiting, and you can end up quite dry. Dehydration is behind some of the classic hangover feelings: thirst, a dry mouth, dizziness and tiredness.

Giving fluid through a drip is a standard, well-understood way to rehydrate someone. It skips your stomach entirely, which is the real advantage when you’re nauseous. If every sip of water comes straight back up, a drip can get fluid in when drinking can’t.

Do hangover IV drips work? What the evidence says

This is where we need to be careful. Hangovers themselves are surprisingly poorly understood. Dehydration is only one part of them. Alcohol also affects sleep, blood sugar, the stomach lining and inflammation in the body, and fluids don’t fix all of that.

There’s very little good-quality research testing IV drips as a hangover treatment. And there’s no solid evidence that vitamins given through a drip make a hangover end sooner. We include them because they’re a common part of the formula, not because we can promise they make a difference.

What helps many people most is simpler: fluids, rest, and if they’re suitable, medicine for nausea and pain. Those can also be taken by mouth if you can keep them down.

What a hangover drip can’t do

• It can’t sober you up. Your liver clears alcohol at its own pace. A drip doesn’t speed that up.
• It can’t undo poor sleep. Alcohol disrupts deep sleep, and you may still feel tired after a drip.
• It can’t protect you from the next night. Having a drip doesn’t make heavy drinking safer.
• It isn’t treatment for alcohol poisoning. Someone who is confused, very drowsy or hard to wake needs a hospital, not a home visit.

Who should skip a hangover drip

A drip isn’t for everyone. Tell us when you book if you’re pregnant or breastfeeding, have heart or kidney disease, or are under 18; the nurse may refer you to a doctor. Our guide is an IV drip safe? covers side effects and what to check before you book. If you’re still very drunk or high, the nurse will wait or refer you, because it isn’t safe to start straight away.

You may also not need one. If your hangover is mild, you can keep water down and you have a quiet day ahead, home care is usually enough.

Cost: a drip versus water and electrolytes

Here’s a fair comparison. Our Hangover Recovery drip starts from ฿3,500, including the nurse’s visit and all equipment. A big bottle of water, a sachet of oral rehydration salts and some plain food cost a small fraction of that at any 7-Eleven.

What you get	Water and rehydration salts	Hangover IV drip
Cost	Very low	From ฿3,500
Speed of rehydration	Slower, over several hours	Faster, over 45–60 minutes
Works if you’re vomiting	Hard to keep down	Yes, it bypasses the stomach
Nausea and pain relief	Tablets, if you can keep them down	Given by the nurse if suitable
Effort	You do it yourself	A nurse comes to your room

For a mild hangover, the cheap option is often just as good. Our hangover cure guide for Thailand lists what to buy and what actually helps.

When a drip makes sense

A drip is most useful when you’re vomiting and can’t rehydrate yourself, when you feel too unwell to get to a pharmacy, or when you have a flight, ferry or long day ahead and need to feel steadier sooner. That’s often the case the morning after a big party, which is why many people book a Full Moon Party hangover drip the day before.

If that sounds like you, our hangover IV drip on Koh Phangan comes to your villa, hotel or bungalow. A nurse usually arrives in about 45 minutes, every day from 8:00 to 22:00.

If you’re not sure whether someone has simply drunk too much or has alcohol poisoning, treat it as an emergency. Put them on their side, stay with them and call 1669.

The honest verdict

Hangover drips are good at one thing: rehydrating you quickly, especially when you can’t keep fluids down. With anti-nausea medicine and pain relief, when suitable, many people feel noticeably better within a few hours. They aren’t a cure, the vitamin part is unproven, and they don’t replace water, food and sleep.
