A doctor-led weight programme in Colombo: assessed, prescribed and supervised.
book a consultationMounjaro is a brand name for tirzepatide, a prescription-only medicine used within medical weight management. It is not a cosmetic product and it is not something a patient can decide to start alone. In Sri Lanka, as in most countries, it can only be prescribed by a doctor, for a suitable patient, after a clinical assessment, and it should be reviewed by that doctor for as long as treatment continues.
Tirzepatide acts on two gut hormone pathways at once, GIP and GLP-1. It slows how quickly the stomach empties and reduces appetite signalling, so most patients feel full sooner and stay full longer. It does not burn fat directly; it makes a reduced-calorie way of eating easier to sustain, which is where the change comes from. It is considered here only inside a supervised programme, and the starting point is always a consultation.
Eligibility comes from your medical history and clinical measurements, not from how much weight you would like to lose.
This list is not exhaustive. Gallbladder disease, diabetic eye disease, kidney problems and several other medicines also need review first.
| Step 1: Consultation | Medical history, current medications, measurements, goals and eligibility assessment |
|---|---|
| Step 2: Decision | The doctor decides whether tirzepatide is appropriate; if it is not, alternatives are discussed |
| Step 3: Starting dose | If prescribed, treatment begins at the lowest strength, with each weekly dose given as a shot in clinic |
| Step 4: First review | Roughly four weeks in, checking tolerance, side effects and progress before any dose change |
| Step 5: Further reviews | At intervals of no less than four weeks while the dose is stepped up, then less often once stable. Increases are never automatic |
| Step 6: Ongoing support and exit plan | Diet and activity guidance runs throughout, and how to step down or stop is agreed before you start |
Tirzepatide has real side effects, and you should know them before you decide rather than afterwards.
The cost of Mounjaro in Sri Lanka is the most common question we are asked, and a single headline figure would mislead you. The total is made up of the consultation and review appointments, the medicine at whichever strength you are prescribed, and how long you remain on treatment. Tirzepatide is supplied at several strengths, so the monthly cost early in a programme is not the cost several months in.
What we give you at consultation instead is the full breakdown: the consultation fee, the current cost at your own prescribed strength, the review schedule, and what a realistic first three months would total. If the programme is not affordable or not clinically suitable, we will say so and talk through the alternatives.
Tirzepatide (Mounjaro) is a prescription-only medicine. This page is general information about a clinical service. It is not medical advice, not a recommendation to use any particular medicine, and not an offer to supply one. No medicine is prescribed without an individual medical assessment by a doctor, and suitability can only be determined at consultation.
Please do not obtain this medicine from unregulated sources. Use without medical assessment and supervision carries genuine risk, including missed contraindications and unmanaged side effects.
For how these medicines work, what the published trials reported, and how tirzepatide compares with semaglutide, our guide covers it in detail.
Mounjaro vs Ozempic in Sri Lanka: How They Work, What the Trials Showed
Tirzepatide, the medicine known by the brand name Mounjaro, is prescription-only. It can be prescribed only by a doctor, for a suitable patient, after a clinical assessment. At our Colombo clinic it is considered within a supervised weight management programme, and only if the assessment shows it is appropriate for you.
We do not publish a fixed figure, because cost depends on the strength you are prescribed, how long you stay on treatment and how many reviews are involved. Doses step up gradually, so early months and later months differ. Your consultation gives you the consultation fee, the current cost at your own strength and the review schedule in writing.
There is no single injection price. Tirzepatide is supplied at several strengths and the strength you are on changes as the dose is stepped up, so someone in their first month is not on the same product as someone six months in. We give you the current figure for your own prescribed strength at consultation.
Yes. A doctor must assess your medical history, current medications and suitability before prescribing, and must keep reviewing you while you are on treatment. Using this medicine without medical assessment and supervision is unsafe, because contraindications can be missed and side effects go unmanaged.
No clinic can promise you a figure. In the SURMOUNT-1 trial of tirzepatide (New England Journal of Medicine, 2022), participants with obesity and without diabetes recorded an average body weight reduction of roughly 15 to 21 percent over 72 weeks depending on dose, alongside a reduced-calorie diet and increased activity. Those are trial averages, and individual results vary considerably.
The most common are gastrointestinal: nausea, vomiting, diarrhoea, constipation, indigestion, abdominal pain and reduced appetite, usually worst after starting or increasing a dose and often settling. Fatigue and injection-site reactions also occur. Less common but serious risks include pancreatitis, gallbladder problems and dehydration severe enough to affect the kidneys.
It is not suitable during pregnancy or breastfeeding, or for anyone with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia type 2, or a history of pancreatitis. Care is also needed with severe gastrointestinal disease, gallbladder disease and diabetic eye disease. This list is not exhaustive, which is why a full assessment comes first.
It can. Slower stomach emptying may reduce how well an oral contraceptive is absorbed, particularly after starting and after each dose increase. Patients on an oral contraceptive are advised to discuss a non-oral method, or to add a barrier method for four weeks after starting and after every increase. Please raise it at consultation.
Appetite typically returns, and published follow-up work shows a substantial part of the lost weight is commonly regained without ongoing support. That is why diet, activity and habit change carry equal weight from the first appointment, and why an exit plan is agreed before you start rather than afterwards.
No. Tirzepatide acts on two gut hormone pathways, GIP and GLP-1, while semaglutide acts on GLP-1 alone. The two have different dose schedules, different published trial programmes, and side-effect profiles that are similar but not identical. Our comparison guide sets out the differences in full.
No. Medical weight management addresses overall body weight through appetite regulation and lifestyle change. Fat freezing and liposuction are body contouring treatments for localized fat pockets in a specific area, and are not weight loss treatments. Goals are discussed at consultation to decide which route fits.
