Who an immune booster IV drip suits
People usually book the Immunity Shield when they’re well but want some extra support. Common reasons include:

- A long trip with lots of flights, ferries and late nights
- A yoga, meditation or wellness retreat with early starts and a light diet
- Feeling run down after weeks of travel
- Wanting a vitamin top-up before heading home or moving on
If tiredness or jet lag is your main complaint, our Myers’ cocktail on Koh Phangan may suit you better. If you’re mostly thirsty and drained by the heat, choose the hydration IV drip.
What’s in our vitamin C drip on Koh Phangan

- High-dose vitamin C. A vitamin your body can’t make itself. It plays a part in the immune system and in healing skin.
- Zinc. A mineral your immune system uses. Most people get enough from food.
- B-complex. A group of vitamins your body uses to turn food into energy.
Honest limits: what it can’t do
A vitamin C drip doesn’t prevent illness, and it doesn’t treat infections. Research on high-dose vitamin drips for healthy people is limited, and there’s no good evidence that a drip keeps colds or stomach bugs away. If you eat a varied diet, you may not notice a difference.

Some people simply enjoy the hour of rest and feel better for it. That’s a fair reason to book, as long as you know what you’re paying for. If you have a fever or think you have an infection, see a doctor rather than booking a drip.
What to expect
Message us on WhatsApp or call with your location. After a few quick health questions, a licensed nurse comes to you, checks your blood pressure and heart rate, and places a small cannula using sterile, single-use equipment. They stay while the drip runs, then remove the cannula and take all waste away.
Who should check with us first
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. If you’re still very drunk or high, the nurse will wait or refer you.

High-dose vitamin C needs extra care. Please tell us if you have kidney problems or have ever had kidney stones, or if you have G6PD deficiency, an inherited condition that affects red blood cells. In these cases, the nurse may refer you to a doctor before giving this drip.
When to go to hospital instead
- Chest pain or trouble breathing
- Confusion, or someone who can’t be woken or won’t respond
- A seizure (fit)
- Vomiting blood, or blood in your stool
- A high fever
- A severe head injury
- You can’t keep any fluids down for 24 hours
- Suspected drink spiking or alcohol poisoning
- Fever with a rash, severe headache or pain behind the eyes
In an emergency in Thailand, call 1669.
Staying well while you travel
- Sleep properly, especially after long journeys
- Wash your hands before eating, and choose busy food stalls
- Drink bottled or filtered water and keep up your fluids in the heat
- Eat plenty of fruit and vegetables, which are easy to find here

Questions
Frequently asked questions
How much is a vitamin C drip on Koh Phangan?
Our Immunity Shield starts from ฿3,900 and takes about 45 minutes. The price includes the nurse’s visit and all equipment. You can pay in cash (THB), by Thai bank transfer or PromptPay, or by card.
Will an immune booster IV drip stop me getting ill?
No. No drip can promise to prevent colds, flu or stomach bugs. Sleep, food, hand washing and safe food and water do more to keep you well while you travel.
Can I have the drip when I already have a fever?
Please don’t book a drip for a fever. A high fever in the tropics needs a doctor, because it can be a sign of an infection such as dengue that needs proper testing.
Why do you ask about kidney stones and G6PD deficiency?
High-dose vitamin C isn’t suitable for everyone. People with kidney problems, a history of kidney stones or G6PD deficiency should tell us first, and the nurse may refer them to a doctor.
Feeling rough? We’ll come to you.
