Immune support IV in Seoul, without the hype

What an immune support IV in Seoul really is

An immune support IV in Seoul is a slow drip of IV fluids combined with nutrients that the immune system uses, such as vitamin C, zinc and B vitamins. At VEI Clinic it is never served from a menu. Dr. HyunSung Park, a board-certified internal medicine specialist and U.S.-educated graduate of the State University of New York, first asks why you want it, checks your vital signs and reviews your medicines and medical history, then decides the contents and dose, or advises against a drip altogether.

People most often ask about it during cold and flu season, before or after long-haul travel, during an exhausting work stretch in Seoul, or while getting over a mild viral illness when eating and drinking have been poor.

What the evidence says, plainly

Your immune system is not something a single drip can switch on. Research on vitamin C shows that regular oral supplements do not prevent colds in most people, though they may slightly shorten them. Zinc may modestly help some colds when started early. Good trials showing that IV vitamins prevent infections in healthy, well-nourished adults are lacking.

Where a drip can genuinely help is hydration. If you have been sweating with a fever, not eating, or traveling for 20 hours, fluids may make you feel noticeably better. People who are actually low in a nutrient, which a blood test can show, may also benefit from correcting it. We prefer to tell you this up front rather than sell you a series of sessions.

Protection with stronger evidence

If your real goal is fewer sick days, these steps have far stronger support than any infusion, and we can help with most of them at the same visit:

• A yearly flu shot, and other vaccines such as hepatitis B if you are not protected
• Seven to nine hours of sleep and regular physical activity
• Checking vitamin D, iron, B12 and thyroid levels if you are constantly tired
• Good control of diabetes, blood pressure and other long-term conditions
• Handwashing and staying home when you are sick

Before a trip or after an illness

Two situations come up most often. The first is a traveler about to fly, or just landed in Seoul, who wants to avoid getting sick on an important trip. Here the most useful steps are making sure routine vaccines are up to date, sleeping on the local schedule as soon as possible and drinking well on the plane. A drip may help if you arrive dehydrated, but it will not shield you from the viruses on board.

The second is someone recovering from a viral illness who still feels drained a week later. In that case the doctor first makes sure nothing else is going on, such as a lingering chest infection, anemia or a thyroid problem, which a simple blood test can check. If the main issue is that you have not been eating and drinking properly, a single drip can be a reasonable way to help you get back on your feet while your appetite returns.

Who it suits and who should not have it

A drip may suit healthy adults who are dehydrated or run-down and understand its limits. It needs extra caution, or should be avoided, if you have heart failure, kidney disease or a history of kidney stones, G6PD deficiency (high-dose vitamin C can cause dangerous breakdown of red blood cells), iron overload, uncontrolled high blood pressure, or if you are pregnant or breastfeeding. Blood thinners and diuretics also change what is safe, so bring your medication list.

When you need medical care instead

A drip is not treatment for an infection. If you have a fever over a few days, a worsening cough, a sore throat with high fever, or burning when you pass urine, you need an examination and possibly tests, which we provide as primary care. Call 119 or go to an emergency room for difficulty breathing, chest pain, confusion, a stiff neck with fever, bluish lips, fainting, or a rash that does not fade when pressed.
