Seasickness treatment in Pattaya
The crossing to Koh Larn is short, the dive boats go further, and the speedboats slam. Seasickness treatment in Pattaya is almost entirely about what you do before you board — because once it has started, tablets swallowed on a rolling deck rarely stay down long enough to work.
What is actually happening
Your inner ear reports movement. Your eyes, fixed on a cabin wall or a phone, report stillness. The mismatch between those two signals is what produces the nausea.
That is why looking at the horizon helps and why reading, scrolling or going below deck makes it worse — you are widening the gap between what you feel and what you see.
It usually builds in stages: yawning, a cold sweat, pallor, excessive saliva, then nausea, then vomiting. Recognising the early stages is what lets you act while acting still works.
Take something before you board
Most preventive medication needs 30 to 60 minutes to work, and it must be swallowed and absorbed before the sickness starts. A tablet taken once you feel unwell frequently comes straight back.
Antihistamine-type tablets are the usual choice and are effective — the trade-off is drowsiness, which matters if you are diving or driving afterwards.
Scopolamine patches, applied behind the ear several hours ahead, last a day or more. They can cause dry mouth and blurred vision, and they are not suitable for everyone — worth asking about rather than assuming.
On the boat
Stay on deck in fresh air, in the middle of the boat where movement is least, and look at the horizon or a fixed point on land.
Do not read, do not scroll, and do not go below to lie down in a cabin, which is the single worst thing available. Straddle a bench facing forward rather than sitting sideways.
Sip water or ginger tea. Eat something light rather than nothing — an empty stomach makes it worse, not better — and avoid a heavy greasy breakfast and alcohol the night before.
Ginger, wristbands and the honest answer
Ginger has reasonable evidence for mild nausea and it is harmless, so it is worth trying. It will not touch severe seasickness.
Acupressure wristbands have weak and inconsistent evidence. They are cheap and harmless, and some people are convinced by them; we are not going to tell you they are useless, and we are not going to tell you they replace medication for a rough crossing.
Fresh air, horizon and the right position on the boat do more than either, and they cost nothing.
Why it matters more than being uncomfortable
Vomiting repeatedly on a hot boat costs a lot of fluid, and you were probably already behind in this climate — see dehydration treatment.
People come in from a day trip genuinely depleted rather than merely queasy, and that is when a drip turns the rest of the day around.
It also makes people careless. Somebody focused on not being sick pays less attention to sun, to footing on a wet deck, and to how much they have drunk — which is why sunburn and seasickness so often arrive together.
Diving and seasickness
This is the combination that needs care. Vomiting underwater is genuinely dangerous, and dehydration is a recognised contributor to decompression illness.
Drowsiness from medication is its own problem at depth. If you are diving, discuss which medication rather than taking whatever is in somebody’s bag — some are much better suited to diving than others.
If you are being sick on the boat before the dive, the honest answer is usually not to dive that day. Tell the divemaster rather than quietly getting kitted up — see dive medicals.
Children and older travellers
Children between about two and twelve are the most susceptible age group, and they are also the least likely to say anything until they are actually being sick.
Doses differ and several adult preparations are unsuitable, so ask rather than halving an adult tablet. Have their rough weight ready.
In older travellers the concern is less the sickness and more the fluid loss and the medication interactions — anticholinergic effects can cause confusion, urinary retention and falls — see prescription refill.
When it is not seasickness
Nausea that begins hours after getting off the boat, or that comes with a fever, is unlikely to be motion sickness. That points at food poisoning — boat lunches sit warm for hours — or at something else entirely.
Severe headache with vomiting, confusion, chest pain, or vomiting that continues into the next day all need assessing rather than attributing to the crossing.
And after diving, any unusual symptom is treated as a diving problem until proved otherwise, not as seasickness. Tiredness, dizziness, tingling or weakness after a dive is not the boat.
Land sickness afterwards
A rocking sensation on dry land for a few hours after a boat is normal and settles on its own.
Occasionally it persists for days — a genuine phenomenon rather than imagination — and while it usually resolves alone, it is worth mentioning if it goes on beyond a few days or comes with hearing changes.
If you have a series of boat days planned, taking something preventively for each is entirely reasonable and does not build tolerance. Ask at the walk-in clinic before the first trip rather than after the worst one.
Most people also adapt over repeated exposure, which is worth knowing if you have written yourself off as somebody who cannot go on boats. The second and third days of a liveaboard or a multi-day dive trip are frequently far better than the first, and giving up after one bad crossing usually means giving up one day too early.
Frequently asked questions
When should I take seasickness tablets?
30 to 60 minutes before boarding. Taken once you feel unwell they frequently come straight back up.
Where should I sit on the boat?
On deck, mid-vessel where movement is least, facing forward, looking at the horizon. Not below deck, which is the worst place.
Does ginger work?
Reasonable evidence for mild nausea and harmless, so worth trying. It will not touch severe seasickness.
Do the wristbands work?
Evidence is weak and inconsistent. They are cheap and harmless, but they do not replace medication on a rough crossing.
Should I skip breakfast?
No. An empty stomach makes it worse. Eat something light and avoid a heavy greasy meal or alcohol the night before.
Can I dive if I have been sick on the boat?
Usually you should not that day. Vomiting underwater is dangerous and dehydration contributes to decompression illness.
Can children take the same tablets?
Doses differ and several adult preparations are unsuitable. Ask rather than halving an adult tablet, and have their weight ready.
I still feel like I am rocking hours later. Is that normal?
Yes, usually. It settles on its own, but mention it if it lasts beyond a few days or comes with hearing changes.
Why a clinic rather than a hospital
English-speaking doctors on site, 24 hours a day. It is worth being straight about what that is for. Pattaya is not short of hospitals, and for anything serious that is where you should be — we will send you and ring ahead. What a hospital handles badly is the small urgent thing at an awkward hour: a wound that needs cleaning properly, a stomach that has emptied itself since midnight, a certificate needed before a morning flight. Those mean a long wait behind real emergencies, at several times the price. That gap, at every hour of the day, is what this clinic is for.
Beyond Pattaya, Doctor Pattaya Takecare Medical Clinic belongs to the Takecare Clinic group, which operates across Chon Buri, Phuket and Krabi. The practical value of that is continuity: if your treatment carries on after you leave, the next clinic already holds your notes, and a referral is a phone call between colleagues rather than a stack of paperwork you have to carry yourself.
Coming in
Doctor Pattaya Takecare Medical Clinic is 24 hours, every day, and that is the building being open with a doctor in it rather than a phone line that answers. No appointment is needed at any point, and there is no hour at which turning up is inconvenient for us. Walk in, or reach us on +66 81 668 5557 or WhatsApp. If you would rather not move, ask for a doctor hotel visit and we will come to you.
If it turns out this needs more than a clinic, that same conversation is where the referral and hospital transfer gets arranged — we stabilise you first, ring the receiving department so you are expected, and organise the ambulance rather than leaving you to find one. In this city that is a short drive at any hour, which is exactly why coming in early costs you nothing.
