Dengue fever treatment in Railay
It begins like flu and gets considerably worse. A fever that climbs fast, a headache sitting behind the eyes, and an ache deep in the bones that earned dengue its old name of breakbone fever. Krabi records dengue every year and cases rise through the rainy months. Dengue fever treatment in Railay starts with a blood test on the peninsula, because knowing changes what you must not take.
Do not take ibuprofen or aspirin
This is the most important sentence on the page. Dengue lowers platelets, the cells that let blood clot. Ibuprofen, aspirin, naproxen and diclofenac all interfere with platelet function independently, and taking them during dengue meaningfully raises the risk of serious bleeding.
Use paracetamol only, within the daily limit on the box. If you have already taken ibuprofen before you knew, do not panic — stop it and tell the nurse.
Climbers reach for ibuprofen more than most people, because it is the standard remedy for sore fingers and elbows and is usually in the bag. That habit is exactly the risk here.
How to recognise dengue
The pattern is reasonably consistent:
- Sudden high fever, often 39 to 40C
- Severe headache, classically behind the eyes and worse on moving them
- Deep muscle and joint pain
- Nausea and vomiting
- A blotchy red rash appearing around day three to five
- Extreme tiredness that outlasts the fever by weeks
Symptoms begin four to ten days after the mosquito bite. The mosquito that carries dengue bites in daylight, particularly early morning and late afternoon — which is when people are walking to and from the crag.
Testing on the peninsula
An NS1 antigen test detects dengue from the first day of fever, and antibody tests add information a few days in. Alongside it we run a full blood count for the platelet level and haematocrit, and those are the numbers followed from then on — see blood tests.
Being able to run this here rather than after a boat crossing genuinely matters. There is no reliable way to tell dengue from other tropical fevers by examination alone, and the result changes your pain relief, how closely you need watching, and when it is safe to fly.
The dangerous phase is when the fever drops
This is counter-intuitive and it catches people out. Days four to six, as the temperature falls and you start to feel better, are exactly when severe dengue develops if it is going to. Plasma leaks from the blood vessels and the platelet count reaches its lowest point.
Get to a hospital immediately if you develop severe abdominal pain, persistent vomiting, bleeding from the gums or nose, blood in vomit or stool, black tarry stools, difficulty breathing, cold clammy skin, restlessness, or a sudden collapse in energy just as the fever settles.
On Railay that means a boat, so the threshold for deciding drops in the evening — see evacuation and hospital transfer. Anyone recovering from dengue here should have someone checking on them daily through that window rather than being left to sleep it off in a bungalow alone.
How it is managed
There is no antiviral for dengue. Treatment is supportive, and supportive treatment works: fluids, paracetamol, rest and monitoring of the blood count. Most people recover fully with daily review.
Fluid is the mainstay. If you cannot keep water down, an IV drip does the job properly. We repeat the blood count daily through the critical phase and arrange transfer if platelets fall far or warning signs appear.
Expect fatigue for two to four weeks after the fever has gone. That is normal, it is not a relapse, and it is the part climbers are least prepared for — you will not be climbing at your usual level for a while, and pushing it simply extends the tail.
Avoiding it for the rest of your stay
There is no useful vaccine for a short trip, so prevention is entirely about not being bitten.
Use repellent containing DEET or picaridin and apply it during the day, not just in the evening — this is a daytime biter and that single fact defeats most people’s routine. Reapply after swimming and heavy sweating.
Empty standing water around your bungalow: plant saucers, buckets, pooled water on balconies and in unused bathrooms. Aedes mosquitoes breed in remarkably small volumes of clean water and rarely travel far, so the one biting you was born close by. A fan helps, since they are weak fliers.
Having had dengue once does not protect you. There are four types, and a second infection with a different type carries a higher risk of severe disease.
Frequently asked questions
How much does a dengue test cost?
The rapid NS1 test is inexpensive and usually run with a full blood count, which is also modestly priced. You are quoted for both before any blood is taken.
Can a doctor test me at my bungalow?
Yes. A doctor resort visit can take the sample in your room, which suits someone flattened by fever. Results follow from the clinic laboratory.
Can I fly home with dengue?
Not during the fever or the critical phase. Once the fever has settled, platelets are recovering and you are eating and drinking normally, flying is usually fine. Get assessed before rebooking.
Can I catch dengue twice?
Yes, there are four types. A second infection with a different type carries a higher risk of severe dengue, so previous dengue is a reason for more caution rather than less.
How long does it last?
The fever typically runs three to seven days. The exhaustion afterwards commonly lasts two to four weeks. That tail is normal and does not mean something has gone wrong.
Is it contagious?
Not directly between people — it spreads only through mosquito bites. But if a climbing partner has it, you are in the same place as the mosquitoes that gave it to them.
A nurse-led clinic, part of the Takecare network
Takecare Clinic Railay is staffed by experienced English-speaking nurses, and works together with Doctor Ao Nang Takecare Medical Clinic in Ao Nang. The two clinics share doctors, records and treatment plans, so a doctor is involved whenever one is needed — reviewing a case, prescribing, or coming over to Railay — and care started on the peninsula continues without repetition if you cross to the mainland. It also means a second clinical opinion is a phone call away rather than a boat ride.
Come in, or we come to you
Takecare Clinic Railay is open 8am–10pm daily on Railay, and reachable 24 hours by phone, WhatsApp and Line — so if something happens after we close, message rather than wait until morning. Walk in without an appointment, call +66 81 718 9080, message WhatsApp or Line. If you would rather not move, ask for a doctor resort visit and we will come to you. For anything that cannot wait for a boat, see evacuation and hospital transfer.
