Running out of a regular medicine is one of the most common reasons long-stay visitors come to see me. Most everyday medicines can be continued safely, but some controlled drugs are restricted or unavailable in Thailand. So I always ask to see the original packaging or prescription.
Lost luggage, a trip extended by a week, tablets left in a hotel safe on another island: people run short of regular medicines in Phuket for all sorts of ordinary reasons. Most of these medicines, such as blood pressure tablets, inhalers and the contraceptive pill, can be replaced quickly once a doctor knows exactly what you take. The difficulty comes when all we have is a brand name that does not exist in Thailand, or when the medicine is one that Thai law controls tightly. Knowing how the process works saves you a wasted journey.
What to bring so we can match your medicine
The most helpful thing is the original box, blister strip or bottle, even if it is empty. The label shows the generic name, meaning the active ingredient, together with the strength and how often you take it. A photo of the packaging, a copy of your prescription, a letter from your doctor or a screenshot of your pharmacy record from home all work too. Brand names differ between countries, so a tablet you know by one name may be sold here under another. We cannot guarantee a specific brand. What we match is the active ingredient and dose, and if the exact strength is not available, the doctor explains the change, for example two smaller tablets or a close alternative from the same drug class.
How a refill visit works
The doctor asks why you take the medicine, how long you have been on it and whether anything has changed recently. Some medicines need a quick measurement before they are continued: blood pressure for blood pressure tablets and the combined pill, a finger-prick sugar level for diabetes, and a look at your technique for inhalers. Where a blood test is sensible, such as kidney function for some blood pressure and diabetes medicines, our on-site laboratory runs common tests with same-day results. Once the doctor is satisfied, the on-site pharmacy supplies enough to see you through your stay or until you can see your own doctor, with written dosing instructions and an itemised receipt. Not sure whether your medicine is available? A telemedicine consultation lets you show us the packaging on video first.
| Medicine group | Generic examples | What to expect |
|---|---|---|
| Blood pressure | amlodipine, losartan, ramipril | Blood pressure check; heat and dehydration can push readings too low |
| Cholesterol | atorvastatin, rosuvastatin | Usually simple to continue |
| Diabetes | metformin, gliclazide, insulin | Sugar check; insulin types vary, so ask us on WhatsApp whether yours is in stock today |
| Asthma and COPD inhalers | budesonide-formoterol, salbutamol | Review of how often you need your reliever |
| Thyroid | levothyroxine | Matching the exact strength matters |
| Contraception | combined pill, progestogen-only pill | Blood pressure check for the combined pill |
| Mood and anxiety | sertraline, fluoxetine | Continuing an established dose is usually possible |
| Controlled medicines | oxycodone, zolpidem, diazepam, ADHD stimulants | Tightly restricted; some cannot be supplied, others have strict limits |
Controlled medicines: what Thailand restricts
Thailand regulates some medicines more strictly than many travellers expect. Strong opioid painkillers such as oxycodone and morphine, many sleeping tablets and benzodiazepines such as diazepam and alprazolam, and stimulants used for ADHD fall under Thai narcotics and psychotropic substances laws. Some are not available in Thailand at all, some cannot be dispensed by a clinic, and others are limited to small quantities after an in-person assessment. We tell you honestly what is possible, suggest safe alternatives where they exist, and refer you to a hospital specialist when that is the right route. If you travel with a controlled medicine, carry your prescription or a doctor’s letter, keep it in the original packaging, and check the Thai Food and Drug Administration’s current rules on quantities and permits before you fly.
Heat, stomach bugs and your regular tablets
Phuket’s heat and the ease of picking up traveller’s diarrhoea both affect medicines. If you become dehydrated through sweating, vomiting or diarrhoea, some blood pressure tablets, water tablets (diuretics), metformin and anti-inflammatory painkillers can strain the kidneys or drop your blood pressure too far. Doctors often give sick day guidance, which means pausing certain medicines until you are eating and drinking normally again, so ask us before stopping anything. Vomiting or severe diarrhoea can also stop the contraceptive pill working; follow the missed-pill advice in the leaflet and use condoms until you are protected again.
Insulin needs particular care. Unopened pens belong in a fridge, and the pen in use can usually stay at room temperature for about four weeks, but a Phuket afternoon can exceed the maximum temperature printed on the leaflet. Keep it out of direct sun and never leave it in a parked car or under a scooter seat.
When to see a doctor
Running out is not usually an emergency, but for some medicines a gap is risky. See a doctor the same day if you take medicine for epilepsy, heart rhythm problems, blood thinning, type 1 diabetes, an organ transplant, Parkinson’s disease or HIV, or if you have suddenly stopped steroid tablets, an antidepressant or a beta-blocker. Stopping long-term steroid tablets abruptly can cause a dangerous fall in the body’s own steroid hormone. Call 1669 or go to a hospital emergency department for a seizure, chest pain, breathlessness that your reliever inhaler does not ease, confusion or drowsiness with very high or low blood sugar, or swelling of the lips or tongue.
Prevention and early detection
Pack twice what you expect to need, split between your hand luggage and a second bag, so one lost case does not leave you with nothing. Carry a list of your medicines with generic names, strengths and doses, plus a doctor’s letter for anything controlled. When you get a replacement, check that the active ingredient and strength on the new pack match what you expected, and if something bought over the counter does not seem to work as usual, get it checked rather than taking more. For long-stay visitors, a review every few months is a chance to catch rising blood pressure or blood sugar early.
Getting your medicines sorted at Takecare Clinic
All three of our clinics are open 24 hours a day, every day: the Bangtao (Cherngtalay) clinic, the clinic in Kata-Karon and the Patong clinic. A walk-in doctor in Phuket can usually see you within minutes, and the pharmacy is on site. To check availability first, send a photo of your packaging on WhatsApp or call +66 81 718 9080. If you are too unwell to travel, book a doctor hotel visit in Phuket. For claims, we bill most travel insurers directly or give you an itemised receipt that lists each medicine by its generic name.
Related services and treatments
If a flare of a long-term condition has left you breathless, our page on asthma treatment covers inhaler reviews and attacks. Missing work because of illness while away? We can issue a medical certificate in Phuket. Flying home with a condition the airline asks about may need a fit-to-fly certificate, and you can see all our medical services in one place.
Summary
A prescription refill in Phuket is usually straightforward for common long-term medicines: bring the packaging or prescription, see a doctor, have any quick checks done and collect your supply from the on-site pharmacy. Expect the brand to differ, and expect strict limits or refusals for controlled medicines such as strong painkillers, sleeping tablets and ADHD stimulants. The practical takeaway is to photograph your medicines before you travel and contact us before you run out, not after.
“Bring the box, the blister pack or your prescription from home. The generic name and dose let me find the right equivalent quickly and safely.”

Frequently asked questions
Can you give me exactly the same brand I use at home?
Sometimes, but we cannot guarantee it. Many medicines are made by several companies and sold under different names in each country. We match the active ingredient and strength, which is what matters clinically. If you want to know whether a particular product is in stock today, send us a photo of your packaging on WhatsApp.
Do I need a prescription from my own doctor?
Not always. For common medicines such as blood pressure tablets or inhalers, the packaging or a photo of it is usually enough for our doctor to assess you. Controlled medicines are different: you need documentation, an in-person review, and even then some cannot be supplied in Thailand at all.
How long does a refill visit take?
Most walk-in visits take under 30 minutes, and if the medicine is in stock our on-site pharmacy dispenses it before you leave. If the doctor wants a blood test first, common tests come back the same day. Insulin and less common medicines can take longer to source, so message us early.
Do I need to book an appointment?
No. You can walk into any of our three clinics at any hour. A quick WhatsApp message with a photo of your medicine is still worthwhile, because we can tell you in advance whether it is available and confirm the price before your visit, which may save you a trip.
Can a doctor come to my hotel if I am unwell and have run out?
Yes. A doctor can visit your hotel, villa or condo anywhere in Phuket, 24/7, review your medicines and examine you if something else is wrong. This is useful if you are ill as well as out of tablets, or if missing doses has already made you feel unwell.
Will my travel insurance cover the cost of replacement medicine?
It depends on the policy. Routine refills for long-term conditions are often excluded or limited, while lost or stolen medicine is sometimes covered, occasionally only with a police report. Check your policy wording. We confirm the price on WhatsApp before your visit and give you an itemised receipt for any claim.
