Wegovy — the Weekly Weight Loss Injection, Done Properly

Yes — Wegovy (semaglutide 2.4 mg) is available in Singapore as a prescription-only medicine. It is prescribed after a medical assessment confirms you meet the eligibility criteria, and used under doctor supervision with scheduled reviews.

They contain the same molecule, semaglutide. Ozempic is registered for type 2 diabetes; Wegovy is the higher-dose formulation registered specifically for weight management with its own titration schedule. Which is appropriate — if either — is a prescribing decision made on your medical picture.

Semaglutide mimics the gut hormone GLP-1: it signals fullness to the brain, slows stomach emptying and steadies insulin response. Appetite falls naturally, portions shrink, and the constant urge to snack quietens — which is why it outperforms willpower-based dieting in trials.

Responses vary genuinely between individuals, and Singapore's advertising rules rightly prevent outcome promises. What can be said: the randomised STEP trials showed substantially greater loss with semaglutide 2.4 mg than lifestyle change alone, and your own trajectory is reviewed against your plan at each visit.

Eligibility follows BMI thresholds, adjusted downward when weight-related conditions such as pre-diabetes, hypertension or obstructive sleep apnoea are present. It is confirmed at medical assessment — pursuing it below criteria, or from unregulated online sellers, carries real risk.

Nausea, reflux and constipation are common early and usually settle with slow titration. Gallbladder disease and pancreatitis are recognised, less common risks; muscle loss is a practical concern the programme actively manages. Your personal risk picture is discussed before any prescription.

The pen uses a very fine needle into the skin of the abdomen, thigh or arm; most patients describe it as barely felt. You are taught the technique at the first visit and inject at home on the same day each week.

Rapid weight loss deflates the structural fat that supports the face — the pattern nicknamed “Ozempic face”, which applies to semaglutide by any brand name. Slower, supervised loss with muscle preservation reduces it, and a dedicated restoration pathway exists if it has already happened.

Appetite signalling returns when the medication stops, and regain is common without a maintenance plan — that is physiology, not weakness. This is why the exit strategy is designed at the start of the programme, not at the end.

Not legally in Singapore. Sellers offering it without a doctor's assessment are the warning sign — counterfeit and mishandled GLP-1 products are well documented, and an unscreened prescription skips the safety checks that make this medicine appropriate.

They work on different receptor combinations (Wegovy on GLP-1; Mounjaro on GLP-1 and GIP), and both have published trial support. “Better” is individual — history, tolerability, response and availability all matter, and that is what the assessment weighs.

Prescription medicine pricing is not advertised. Cost depends on dose stage and programme structure, and is set out transparently at consultation before you decide anything.
