A hangover IV drip in Bangkok is easy to find. Clinics on Sukhumvit and Silom advertise walk-in drips, and mobile services will come to your hotel room. The pitch is simple: a bag of fluids and vitamins, and you feel human again in under an hour.
Compare IV therapy clinics carefully
Review clinical screening, proposed benefit, transparent cost and alternatives.
The reality is more modest. A drip can rehydrate you, and some contain anti-nausea medicine that may help you feel better. But the evidence that drips do more than drinking fluids is thin, and a drip is not the right answer if you are genuinely unwell. For a broader view of IV services, see our IV therapy guide.
What's usually in the bag
Most hangover and hydration drips share a similar base. Ingredient lists vary between providers, and some do not publish full formulations, so always ask.
- A fluid base. Usually sterile saline or lactated Ringer's solution. This is what actually rehydrates you.
- Electrolytes. Often already present in the base fluid; some providers add more.
- B vitamins. Commonly included. One Silom clinic, for example, lists B vitamins and electrolytes for its hangover drip.
- Vitamin C, zinc or antioxidants. More common in "immune" or "vitamin" drips than in basic hydration bags.
- Medicines. Some drips include anti-nausea or anti-inflammatory medication. These are prescription drugs, so a doctor should approve them for you specifically.
Ask the clinic for the named ingredients and doses before the needle goes in. If staff cannot tell you what is in the bag, do not have it.
Drip vs oral rehydration
The key question is whether you need fluids through a vein at all.
What the evidence says about hydration
For mild to moderate dehydration, oral rehydration works very well. A Cochrane review of 17 trials in children with gastroenteritis found no clinically important difference between oral and IV rehydration, and recommended oral fluids first, with IV reserved for when the oral route fails. IV therapy also carried a higher rate of vein inflammation. That review was in children with stomach bugs, not adults after a night out, but it shows how effective drinking can be.
What the evidence says about alcohol
Studies on IV fluids for alcohol are not encouraging. In a randomised trial of 144 adults with uncomplicated alcohol intoxication in Australian emergency departments, a saline bolus did not shorten time in hospital or improve intoxication scores compared with observation alone.
For hangovers specifically, a 2022 systematic review in the journal Addiction looked at 21 placebo-controlled trials of hangover remedies. All the evidence was rated very low quality, and the researchers found no convincing proof that any remedy worked. IV vitamin drips were not among the products tested, and no good trials of them were found for this guide.
What that means for you
If you can keep fluids down, a rehydration sachet, water and some food will usually do most of what a hydration drip does, for a fraction of the price. A drip may make more sense if you are vomiting and cannot drink, but at that point a medical assessment is the better choice. That is not the same as a spa-style vitamin service.
The same logic applies to an IV after a flight. Long-haul travel can leave you mildly dehydrated, but water, an electrolyte drink, daylight and sleep usually handle it. Our guide to recovery after a long flight covers the first day in Bangkok.
Typical Bangkok prices
Prices vary by ingredients, setting and whether a doctor sees you first. Treat these as figures seen in public listings in 2026, and confirm directly.
| Setting | What listings showed | Notes |
|---|---|---|
| Walk-in clinic, hangover drip | THB 1,500 at one Silom clinic | B vitamins and electrolytes listed |
| Walk-in clinic, other vitamin drips | THB 1,000–2,000 at the same clinic | Energy, immune and skin drips |
| Hotel or home visit | Usually priced above walk-in drips | Ask whether call-out fees are included |
When comparing a vitamin drip in Bangkok, ask:
- Is a doctor's consultation included, or charged separately?
- What exactly is in the bag, and at what doses?
- Are anti-nausea or other medicines included, and who prescribes them?
- Is there a call-out, travel or late-night surcharge?
- What happens, and what does it cost, if you react badly?

Hotel call-out services: what to check
Mobile drip services market themselves heavily to hotels, and convenience is real when you feel awful. But a hotel room is not a clinic, so the checks matter more.
- Who is coming? Ask whether a doctor or a registered nurse will insert the cannula, and whether a doctor has reviewed your health information first.
- Screening. A responsible service should ask about allergies, medicines, heart or kidney problems, pregnancy and how much you drank. Some listings only ask you to mention allergies and medicines; that is a minimum, not a screening.
- Licensing. Ask which licensed clinic the service operates from. You can check a clinic's licence status on the Thai Department of Health Service Support database.
- Sterile equipment. Needles, cannulas and bags should be single-use and opened in front of you.
- Monitoring. Someone should stay with you for the whole infusion, not set it running and leave.
- What if something goes wrong? Ask how they handle a reaction, and which hospital they would transfer you to.
- Your hotel's view. Some hotels have rules about outside medical services; check with reception.
Stop the infusion and tell the staff straight away if you feel chest tightness, breathlessness, a racing heart, swelling, rash, or pain or swelling around the needle site.
Symptoms that need a doctor instead
A hangover drip is for feeling rough, not for being ill. Seek medical care, not a vitamin drip, if you or a friend have any of the following.
Call emergency services if there are signs of alcohol poisoning:
- Confusion, or difficulty staying awake or being woken
- Seizures
- Slow or irregular breathing
- Blue, grey or pale skin, or feeling very cold
- Repeated vomiting in someone who is very drunk
Do not leave an unconscious person alone, and do not try to make them vomit. In Thailand, 1669 is the national emergency medical number.
See a doctor promptly if you have:
- Vomiting that continues for many hours, or you cannot keep water down
- Severe abdominal pain, vomiting blood or black stools
- Chest pain, palpitations or fainting
- A severe headache unlike your usual hangover, or a head injury from the night before
- Symptoms after mixing alcohol with drugs or unfamiliar medicines
- Fever, especially in a dengue area
Dizziness can also come from heat and dehydration rather than alcohol. If you feel light-headed after a sauna session, see our guide to sauna dizziness and fatigue.
People with heart failure, kidney disease, pregnancy or some long-term conditions should not have IV fluids without a doctor's assessment.
Frequently asked questions
How fast does a hangover drip work?
Mobile services typically list sessions of about 30 to 45 minutes. Some people report feeling better soon after, which may partly reflect rehydration, anti-nausea medicine, rest and time. There is no good trial evidence that a vitamin drip works faster than oral fluids for a hangover.
Can I get a drip at my hotel?
Yes, several mobile services in Bangkok offer hotel visits. Check who will treat you, which licensed clinic they operate from and what screening they do. Make sure someone monitors you throughout and that you know the full price, including any call-out fee.
Is a vitamin drip better than taking vitamins orally?
For healthy people eating a normal diet, there is little evidence that IV vitamins offer a meaningful advantage. IV delivery bypasses the gut, but that matters mainly for people with absorption problems or a diagnosed deficiency, which a doctor should manage.
Can I drink again after a hangover drip?
A drip does not protect you from alcohol's effects or speed up how your body clears it. If you plan to drink again, go slowly, eat, and alternate with water. Repeated heavy drinking deserves a conversation with a doctor.
