Allergy Treatment in Patong, Phuket: Same-Day Care for Hives, Anaphylaxis and Allergic Rhinitis 24/7
Antihistamines, intranasal steroids, IM adrenaline for anaphylaxis, and trigger workup for adults and children in Patong, Kalim, and Tri Trang. Clinically reviewed by the Doctor Patong Takecare Clinic medical team.
Allergy treatment in Patong starts with deciding how dangerous the reaction is right now. For itchy hives or runny eyes we give a non-sedating antihistamine such as cetirizine 10 mg or loratadine 10 mg, with a short course of oral prednisolone for severe or widespread cases. For anaphylaxis, defined as breathing difficulty, throat swelling, or low blood pressure with skin involvement, we give intramuscular adrenaline 0.5 mg into the thigh as the first action, then oxygen, intravenous antihistamine, hydrocortisone, and a minimum six-hour observation. We then help you find the trigger and write an action plan.

Allergic reactions in Patong rarely stay convenient. They start at a beach barbecue when a peanut sauce hits a known allergy, in a hotel room thick with dust mite, on a dive boat after a wasp sting, or twenty minutes into a new antibiotic. We keep adrenaline, intravenous antihistamine, hydrocortisone, oxygen, and nebulisers ready around the clock, and we triage the moment you message. Walk in, message on WhatsApp, or ask reception at your hotel to call us.
Common allergens and reactions we see in Patong
The tropical climate concentrates a specific set of triggers. House dust mite thrives in humid hotel mattresses and carpets, mould grows in air-conditioning units and damp bathrooms, and pet dander follows guests on clothing. Food allergens turn up unexpectedly in Thai cooking, especially shellfish, peanut, tree nuts, sesame, and egg used as a binder in unfamiliar dishes. Insect stings from bees, wasps, and fire ants are common on garden paths and dive sites, and jellyfish stings produce overlapping toxic and allergic features. Drug reactions to penicillin, sulfa antibiotics, NSAIDs, and contrast media still account for a steady share of urgent visits, alongside skin irritation from latex, sunscreen ingredients, and henna tattoos. The presentations we treat most often are allergic rhinitis with sneezing and watery nasal discharge, allergic conjunctivitis with itchy red eyes, urticaria or hives with raised itchy wheals, angioedema with deeper swelling of lips and eyelids, and allergic asthma with wheeze and cough.
Acute allergic reaction treatment without airway involvement
For urticaria, mild angioedema confined to the lips or eyelids, or a brisk allergic rhinitis with no breathing difficulty, our first-line treatment is a second-generation oral antihistamine, usually cetirizine 10 mg or loratadine 10 mg, because they control itch and wheals without the sedation of older agents. For severe itch we add diphenhydramine 25 to 50 mg, accepting the drowsiness, and for widespread or persistent hives we give a single dose or short three to five day course of oral prednisolone 30 to 40 mg. We watch every acute reaction for at least one hour after the first dose, because what looks like simple hives sometimes progresses to throat tightness within minutes. If the skin signs are still active at discharge we send you home with a written escalation plan and a contact line that reaches a doctor directly.
Anaphylaxis: how we treat it on site
Anaphylaxis is a rapid, multi-system allergic reaction that can kill within minutes, and the single most important treatment is intramuscular adrenaline. As soon as we identify breathing difficulty, throat swelling, hoarse voice, wheeze, low blood pressure, vomiting, or collapse together with skin or mucosal signs, we give 0.5 mg of 1:1000 adrenaline as a 0.5 mL intramuscular injection into the anterolateral thigh. We then secure intravenous access, give oxygen at 15 litres per minute through a non-rebreather mask, lay you flat with legs raised if blood pressure is low, and add intravenous chlorphenamine 10 mg and intravenous hydrocortisone 200 mg. Adrenaline can be repeated every five minutes if symptoms persist. We observe every anaphylaxis case for a minimum of six hours because around one in twenty patients has a biphasic reaction with symptoms returning after they appear to settle. On discharge you go home with an adrenaline auto-injector prescription, hands-on training in how to use it, and a written anaphylaxis action plan in English.
Chronic allergy control and finding your trigger
For ongoing allergic rhinitis we move you onto a daily intranasal corticosteroid such as fluticasone or mometasone, which is the first-line treatment for moderate to severe symptoms, paired with a second-generation oral antihistamine. Decongestant sprays are useful for two or three days only, because longer use causes rebound congestion. Allergic conjunctivitis responds well to a topical antihistamine and mast-cell stabiliser such as olopatadine 0.1 percent twice daily, with cool compresses for symptomatic relief. Identifying the actual trigger matters as much as the medicine. We take a structured history, and where the picture is unclear we arrange skin prick testing or specific IgE blood tests through our partner allergy specialists. For confirmed airborne allergies we can refer you for sublingual or subcutaneous allergen immunotherapy, and for systemic reactions to bee or wasp stings, venom immunotherapy is an option worth discussing.
Severity grid: how serious is this reaction
| Severity | Signs | Where to treat |
|---|---|---|
| Mild | Localised hives, itchy nose or eyes, sneezing, no swelling or breathing change | Clinic, oral antihistamine, discharge with action plan |
| Moderate | Widespread urticaria, lip or eyelid swelling, mild abdominal cramping, no airway change | Clinic antihistamine plus oral steroid, observe at least one hour |
| Severe (anaphylaxis) | Throat swelling, hoarseness, wheeze, vomiting, low blood pressure, skin involvement | Clinic IM adrenaline, oxygen, IV access, observe six hours, hospital if not settling |
| Life-threatening | Stridor, collapse, loss of consciousness, no response to first dose of adrenaline | Hospital emergency department, call us en route, we coordinate ambulance |
Red flags, give adrenaline if you have it and get to us or a hospital now: any breathing difficulty, wheeze, or noisy breathing, tongue or throat swelling, hoarse voice or difficulty swallowing, feeling faint or actually fainting, persistent vomiting after an exposure, hives plus any of the above, or any reaction that started within minutes of a known trigger such as a bee sting, peanut, shellfish, or a new medication.
See a doctor if hives last more than 48 hours or keep coming back for over six weeks, your nasal symptoms wake you at night or block your ears, antihistamines stop working at standard doses, you have had any reaction to a medication or insect sting, you are pregnant with a new allergic flare, or you are leaving Phuket without an adrenaline auto-injector and a written action plan for a known severe allergy.
Prevention and travel essentials
Avoidance is still the most reliable treatment. Once your trigger is known, we put it in writing on a card you keep with your passport, in your phone, and in your travel companion’s phone. For food allergy we give you Thai-language translation cards for restaurants. For known anaphylaxis you should carry two adrenaline auto-injectors at all times because one is often not enough, and we will check the expiry date and practice the injection technique with a trainer pen before you leave. For dust mite and mould sensitivity we recommend a non-smoking room away from heavy carpet, washing pillow covers in hot water, and asking housekeeping to clean the air-conditioning filter.
Prevention checklist: written allergy and anaphylaxis action plan, two in-date adrenaline auto-injectors for known severe allergy, daily intranasal steroid for confirmed allergic rhinitis, second-generation antihistamine in your travel kit, Thai-language allergy cards for food triggers, medic-alert bracelet, and a clinic phone number saved on the lock screen.
Summary
Allergy care in Patong should match the severity of what is in front of you. Mild reactions get an antihistamine and a plan, moderate reactions add an oral steroid and an hour of observation, and anaphylaxis gets intramuscular adrenaline within seconds and six hours of monitoring before discharge with an auto-injector. The next reaction is easier to survive when you know your trigger and carry the right kit.
“In allergy we never wait to see if it gets worse. If the picture even hints at anaphylaxis, adrenaline goes in first and we explain afterwards. Patients do not die from an adrenaline injection given in error, they die from one that was given too late.” Doctor Patong Takecare Clinic medical team
Frequently asked questions
How quickly do I need to be seen after a suspected anaphylaxis?
Immediately. Anaphylaxis can progress from mild skin signs to airway closure within minutes. If you carry an auto-injector, give it into the outer thigh first, then call us on WhatsApp or by phone while travelling to the clinic or hospital. We will arrange ambulance transfer if you cannot move safely.
Can you prescribe an adrenaline auto-injector before I fly home?
Yes. After any confirmed or strongly suspected anaphylaxis episode we issue an adrenaline auto-injector prescription, demonstrate the technique with a trainer pen, and supply a written action plan in English. We recommend two devices to cover the possibility of a biphasic reaction.
What can I take for hay fever symptoms while I am on holiday?
A daily second-generation antihistamine such as cetirizine or loratadine handles mild allergic rhinitis. If symptoms are bothering you most days, we add an intranasal corticosteroid spray such as fluticasone, which is the most effective single treatment for moderate or severe nasal allergy and is safe for daily use.
Do you do allergy testing at the clinic?
We do not run skin prick tests on site, but we arrange them and specific IgE blood tests through partner allergy specialists in Phuket, and we interpret the results with you at follow-up. Most travellers find a structured history plus targeted testing is enough to identify the trigger.
My child has a peanut allergy and we are travelling to Phuket, what should I bring?
Bring two in-date adrenaline auto-injectors at the correct paediatric dose, a written anaphylaxis action plan, a supply of liquid antihistamine, and Thai-language allergy cards listing peanut and tree nuts. Peanut and cashew are common in Thai cooking, so we recommend showing the card at every meal and avoiding open-pan stalls.
I was stung by a wasp last year and felt unwell, what should I do now?
Any systemic reaction after a sting raises the risk of a worse reaction next time. Carry an adrenaline auto-injector while in Phuket, avoid known nest sites and sweet drinks left uncovered outdoors, and ask us about referral for venom immunotherapy when you return home, as it is a long-term treatment that can prevent future anaphylaxis.
