What weight loss injections cost in Bangkok
On 3 November 2026 we looked for the weight loss injection prices that Bangkok hospitals and clinics publish on their own websites. One hospital, which updated its Saxenda page in March 2026, and one clinic, which updated its promotion and price list in October 2026, publish them:
| Medicine | Published prices |
|---|---|
| Saxenda (liraglutide) | At the hospital, a programme with a doctor's check-up, blood tests and a body composition analysis: 14,500 baht with 3 pens, 25,500 baht with 6 pens, or 37,500 baht with 9 pens and an ultrasound of the upper abdomen. Each extra pen is 4,200 baht. |
| Mounjaro | At the clinic, by dose: 8,999 baht for 2.5 mg, 9,999 baht for 5 mg, 14,400 baht for 7.5 mg, 17,000 baht for 10 mg, 21,499 baht for 12.5 mg and 23,999 baht for 15 mg. |
| Wegovy | At the clinic, by dose: 2,999 baht for 0.25 mg, 8,800 baht for 0.5 mg, 9,500 baht for 1 mg, 13,500 baht for 1.7 mg and 16,500 baht for 2.4 mg. |
| Ozempic | 9,500 baht for 1 mg at the clinic. |
The hospital says its programme prices do not include treatment fees, and that follow-up visits are charged for the doctor and the hospital. The clinic's list gives one price per dose but does not say whether that is one pen or how many weeks it lasts. Ask both, and work out the cost per month and per year.
The clinic also lists Rybelsus, a tablet rather than an injection, at 9,200 to 9,980 baht by dose.
What these medicines are
They are prescription medicines. The hospital says Saxenda, which contains liraglutide, copies a hormone called GLP-1: it slows the emptying of the stomach and reduces hunger. The clinic says Mounjaro acts on two hormones, GLP-1 and GIP, and was first used for type 2 diabetes. Both say the medicine is used together with a lower-calorie diet and more activity.
The hospital says Saxenda is for adults with a body mass index (BMI) of 30 or more, or of 27 to 30 with a weight-related condition such as diabetes, high blood fats, high blood pressure or sleep apnoea, and that a doctor should decide whether it suits you.
How the dose goes up
Saxenda is injected once a day under the skin of the thigh, upper arm or tummy. The hospital says it starts at 0.6 mg a day and rises by 0.6 mg each week to 3 mg; if you have not lost at least 5% of your starting weight after 12 weeks at 3 mg, treatment should stop, and a doctor should review it every year.
Mounjaro is injected once a week, on the same day, from a pre-filled pen. The clinic says doctors usually start at the lowest dose for four weeks, then may raise it step by step to as much as 15 mg. At the clinic's prices, a higher dose costs more, so the first months are the cheapest.
Side effects and storage
The hospital says the most common side effects of Saxenda, affecting more than 1 in 10 people, are nausea, vomiting, diarrhoea and constipation. The clinic lists nausea, vomiting, diarrhoea, constipation and tummy pain for Mounjaro, and says they usually ease as the body adjusts.
The clinic says Mounjaro pens are kept in a fridge at 2 to 8°C and must not be frozen. If you plan to take pens home, ask how to keep them cold on the journey and how you will get further supplies.
Check the doctor
Only a doctor registered and licensed by the Medical Council of Thailand may practise medicine (Medical Profession Act 1982, section 26). You can check a doctor on the Medical Council's website by searching their first name and surname, in Thai or in English. It lists only licensed doctors. If you find nothing, the Council answers on 02-590-1887.
No one may present themselves as skilled in a field of medicine unless they hold the Medical Council's certificate for it, or one the Council recognises, or meet criteria set in the Council's regulations (section 28). Ask which certificate your doctor holds, and check the name you are given.
What to ask before you pay
- Is the price for one pen, and how many weeks does it last at my dose?
- What will it cost per month as the dose goes up?
- Are the consultation, blood tests and follow-up visits included?
- Which medicine do you suggest for me, and why?
- How do I keep the pens cold on the flight, and get more at home?
- What is the prescribing doctor's full name?
