8 Best Xenical Clinics in Singapore (2026)

Before the list, here is how I weighed these clinics. Xenical Singapore is a health decision, not a beauty purchase, so my criteria are about safety, honesty, and aftercare rather than before-and-after marketing.

• Doctor-led and HSA-compliant. The 120mg version is a prescription-only medicine under the Health Sciences Authority, so a proper consultation and prescription are non-negotiable. Be wary of anywhere offering it without one.
• Honest about the side effects. A clinic I trust is upfront that orlistat causes oily, loose stools when you eat fatty food, and frames that as the low-fat diet doing the work, not a flaw to hide.
• Clear dietary and vitamin guidance. Because orlistat can reduce absorption of fat-soluble vitamins, the doctor should give practical low-fat eating advice and usually recommend a fat-soluble vitamin or multivitamin taken at a separate time of day.
• Honest eligibility assessment. A good clinic checks whether medication is actually appropriate, usually against the lower Asian BMI thresholds the Health Promotion Board uses, and is willing to say no if it is not.
• Treats it as one tool, not a cure. Orlistat works best alongside diet and lifestyle change. I rate clinics that present it as one tool among several rather than a guaranteed result.

Most clinics treat weight loss as one service among many. Edwin Lim runs a dedicated, doctor-led weight loss clinic, and that focus is exactly why it leads my list for Xenical. It carries the full modern range of doctor-prescribed options under one roof, from oral medications like orlistat through to the GLP-1 injections, so the doctor can match the treatment to you rather than to whatever the clinic happens to stock.

For Xenical specifically, that breadth matters. Orlistat is a fat blocker that works in the gut, not an appetite suppressant or an injection, so it suits a particular kind of person, and a clinic with the full toolkit can tell you honestly whether it is the right fit or whether something else would serve you better. If you want the widest medication choice with proper doctor oversight, this is where I would start. For the bigger picture, see my guide to the best weight loss clinics in Singapore.

DTAP Clinic (Dr Tan & Partners) is one of the more accessible options here, an established multi-branch GP group that lists orlistat on its weight programme alongside everyday primary care. The appeal is reach and approachability: with branches across the island, you are rarely far from one, and a GP setting can feel less intimidating than a glossy aesthetics clinic for a first conversation about weight.

Because orlistat sits within a broader medical service here, the doctor can also weigh up whether an appetite-based approach might suit you better, which pairs naturally with my guide to the best Duromine clinics. For straightforward, accessible orlistat access with a doctor, DTAP is a solid choice.

ATA Medical runs a doctor-led obesity-management programme that lists orlistat among its options, and I like that it frames weight as a medical problem to manage rather than a quick cosmetic fix. The programme structure means orlistat is prescribed after an assessment, with the dietary and follow-up support that makes a fat blocker actually work.

With four clinics across Tanjong Pagar, Orchard, Jurong East, and Novena, it is convenient from both the CBD and the west. For someone who wants orlistat within a proper, structured obesity programme rather than a one-off prescription, ATA Medical is a sensible pick.

Shim Clinic is an in-person GP clinic in Bedok that lists Xenical and orlistat by name, which makes it a refreshingly direct option if you already know that orlistat is what you are after. There is no dressing it up as a lifestyle package: you see a doctor, you are assessed, and where appropriate you get a prescription.

For people in the east who want a simple, no-frills route to a Xenical prescription with a doctor, this is an easy clinic to recommend. As always, the doctor will confirm whether the 120mg version is suitable for you before prescribing.

Little Cross Family Clinic is a long-running family clinic in Tampines, established in 1999, that offers Xenical (orlistat) as part of its everyday GP services. There is a particular comfort in getting weight loss medication from the same kind of neighbourhood doctor you would see for anything else, and that familiarity can make the first conversation a lot easier.

For heartland residents in the east who would rather not travel into town for an aesthetics clinic, Little Cross offers genuine family-clinic access to orlistat with a doctor who can also look at your wider health. It is a practical, grounded choice.

The Pegasus Clinic is a heartland family-medicine clinic in Bishan that offers the full oral and GLP-1 range, with evening and Sunday hours that make it genuinely usable for people working full-time. Orlistat sits within that range, so the doctor can talk you through how a gut-acting fat blocker compares with the appetite and injectable options before you commit.

The extended hours are the standout. If your schedule makes weekday-daytime appointments hard, a clinic open in the evenings and on Sundays removes a real barrier to actually following through. For accessible, doctor-led orlistat in the central heartlands, Pegasus is a strong option.

Siena Health is doctor-led telehealth for people who would rather not sit in a waiting room. It is an MOH-licensed teleconsult service: you have a video consultation with a doctor, and where orlistat is appropriate, the medication is delivered to your home. For a medicine like orlistat, where the main ongoing question is sticking to a low-fat diet rather than complex monitoring, that convenience makes a lot of sense.

Telehealth is not the right starting point for everyone, but for a busy professional who is clear on what they want and comfortable with a video consult, Siena removes the friction. If you are weighing telehealth options more broadly, my guide to the best Saxenda clinics covers similar ground for the injectable route.

Trimly closes the list as a doctor-led telehealth service with a focus on transparent, all-in pricing and home delivery. With prescription medication, hidden add-ons are a common frustration, so a clinic that quotes one clear figure for the consult and the medication is a welcome change, especially for orlistat where people are often price-sensitive.

It follows the same MOH-licensed teleconsult model: a doctor reviews your suitability, and where orlistat is appropriate it is delivered to your door. For someone who wants the convenience of telehealth with no guessing about the bill, Trimly is a clean, sensible way to end the list.

Because the 120mg version is prescription-only, clinics cannot publicly advertise specific prices, so the figures below are indicative market ranges for 2026, not quotes. Your actual cost depends on the clinic, the consultation, and how much follow-up is included.

These prices are not advertised, and a consultation is required for the 120mg version, so treat the table as a guide for budgeting rather than a fixed menu. Ask each clinic for an all-in figure that includes the consult and any review so you are comparing like with like.

Xenical is orlistat, and it works as a fat (lipase) blocker. After a meal, enzymes called lipases break dietary fat down so your body can absorb it. Orlistat blocks some of those enzymes in your gut, so roughly a quarter to a third of the fat in that meal passes through undigested rather than being absorbed as calories.

What makes it different from most other weight loss medicine is where it acts. Appetite suppressants and GLP-1 injections work on the brain or on hormones to change how hungry you feel. Orlistat does none of that. It works entirely in the gut, with no stimulant effect, which is why it appeals to people who cannot take or do not want a stimulant or an injection. The flip side is that it only helps with the fat you eat, so it rewards a lower-fat diet.

The most talked-about side effects of orlistat are gastrointestinal, and they follow directly from how it works. Because it stops some fat being absorbed, that fat leaves the body instead, which can mean oily or loose stools, more frequent or urgent bowel movements, and oily spotting, especially after a high-fat meal. In practice this acts as a built-in nudge towards eating less fat, because the more fat you eat, the more pronounced these effects are.

Because orlistat reduces the absorption of fat along with some fat-soluble vitamins (A, D, E, and K), doctors usually advise taking a multivitamin, ideally at a different time of day such as at bedtime, so it is absorbed properly. These are general points, not medical advice, so discuss the specifics and any other medication you take with your doctor.

For the 120mg version, yes. Xenical (orlistat 120mg) is a prescription-only medicine regulated by the Health Sciences Authority (HSA), so you need to see a doctor for an assessment and a prescription. No legitimate clinic can sell it to you without that consultation, and none can publicly advertise a specific price for it.

A lower-strength orlistat can be pharmacist-supplied without a doctor's prescription, which is why you may have seen orlistat discussed as an over-the-counter option elsewhere. The two are not the same product, and if your doctor thinks the stronger 120mg dose is right for you, that route runs through a clinic. When in doubt, a quick consultation will clarify which version suits you.

Eligibility is a medical decision a doctor makes with you, but it generally follows body mass index (BMI) thresholds, and Singapore uses lower cut-offs for Asian populations. The Health Promotion Board treats a BMI of 23 and above as higher risk and 27.5 and above as high risk, lower than the global figures of 25 and 30.

In practice, orlistat is typically considered for people who are overweight or obese by these thresholds, often around a BMI of 27 to 30 and above, particularly if you also have a weight-related condition. A responsible clinic will assess your BMI, your health history, and what you eat, and will tell you honestly if orlistat is not the right path. That willingness to say no is one of the clearest signs of a clinic worth trusting.

Not sure this is the right medication for you? Each option works differently and suits a different person, so it is worth comparing. Here are my guides to the other weight loss medications in Singapore, plus the overview that ties them together:
