How to get prescribed Wegovy: what the process actually involves

What does a prescriber actually check before issuing a Wegovy prescription?

A Wegovy prescription is not a formality. A prescriber works through your full clinical picture: your current BMI, any weight-related conditions you've declared, your medication list, and your medical history. Certain conditions rule Wegovy out entirely, a personal or family history of medullary thyroid carcinoma, for example, or multiple endocrine neoplasia type 2. A history of pancreatitis, certain gastrointestinal conditions, and pregnancy or breastfeeding are also grounds for declining to prescribe. The NHS semaglutide page lists the contraindications clearly if you want to read them before you apply.

Beyond the hard stops, the prescriber is making a clinical judgement about benefit versus risk for you specifically. BMI alone doesn't guarantee approval. Someone sitting just at the threshold with several comorbidities and a history of severe nausea on other medicines may need a different conversation than someone presenting straightforwardly. That individual review is what separates a legitimate prescription from a rubber stamp. At our clinical team, this assessment happens the same working day as your consultation.

One practical point worth knowing: if you're already on Wegovy through another provider and want to transfer, a prescriber will still review your case. Dose increases require evidence of your current dose, not just your word for it. That's standard clinical practice, not bureaucracy.

Does the NHS prescribe Wegovy, and what are the alternatives if you can't access it that way?

NICE has recommended semaglutide for weight management in England, but with narrow conditions: it must be used within a specialist weight management service, for a maximum of two years, and the patient must have a BMI of 35 or above alongside at least one weight-related comorbidity (thresholds are lower for some ethnic backgrounds). You can read the full recommendation in NICE Technology Appraisal TA875. In practice, those specialist services often have waiting lists measured in months or longer.

For people who don't meet the NHS threshold, who do meet it but can't face the wait, or who simply prefer the speed and privacy of a private route, a GPhC-registered online pharmacy is the legal alternative. The key word is registered: you can verify any online pharmacy on the GPhC register in under a minute. If a pharmacy isn't listed, walk away. The MHRA has seized tens of millions of doses of illegally traded weight-loss medicines in recent years, including counterfeit pens that contained insulin rather than semaglutide. If you want to understand how to get prescribed semaglutide through a legitimate private route, the process is more straightforward than many people expect.

For context on how private treatment is priced, our guide to buying Wegovy explains what a legitimate private prescription typically includes.

What happens between submitting a consultation and the prescription being issued?

The mechanics differ between providers, but at a regulated service the sequence is: online consultation (health questions, current medications, relevant history), identity and weight verification (at nume, that means photo ID and a live video weight check) and then prescriber review. If the prescriber approves, a prescription is generated and sent to the pharmacy. The pharmacy dispenses, packages, and hands to the courier.

At nume, the whole chain from consultation to dispatch happens the same day for orders placed before midday on a working day. The pen itself arrives the next working day in plain packaging, nothing on the outside to indicate what's inside or where it came from. If you have questions before or after starting, aftercare is available seven days a week. There's no subscription and no auto-renewal; each repeat order goes through clinical review again, which is how it should work for a prescription medicine.

What should you expect once treatment begins?

Wegovy is titrated slowly by design. The starting dose (0.25 mg weekly) isn't intended to produce weight loss; it's there to let your body adjust before the dose steps up. Most people reach the 2.4 mg maintenance dose after about five months of four-weekly increases, though that timeline is decided by the prescriber based on how you're tolerating each step. Our guide to how to prescribe Wegovy covers the titration schedule in detail, including the dedicated single-dose 7.2 mg pen approved by the MHRA in April 2026 for people with a BMI of 30 or above, extending the maximum dose further; availability and suitability are confirmed at consultation.

Side effects are mostly gastrointestinal: nausea, vomiting, constipation, indigestion. They're most noticeable at the start of each new dose level and typically ease within a couple of weeks. Seek urgent medical attention if you develop severe, persistent stomach pain that radiates to the back, that's the warning sign for pancreatitis, a rare but serious complication that the MHRA specifically flagged in a Drug Safety Update in January 2026.
