How to get a Wegovy script: the decisions that matter

Is a Wegovy script something you actually qualify for?

Eligibility is the first fork in the road. The UK licence for Wegovy covers adults with a BMI of 30 or above, or a BMI of 27 to 29.9 alongside a qualifying condition, high blood pressure, type 2 diabetes, dyslipidaemia, obstructive sleep apnoea or cardiovascular disease are the most common. That threshold drops by 2.5 kg/m² for people from South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds, in line with NICE guidance. The NHS medicines page for semaglutide sets out the conditions under which it is used and what to discuss with a clinician before starting.

Meeting the BMI number is necessary but not sufficient. A prescriber will also look at contraindications: a personal or family history of medullary thyroid carcinoma, certain pancreatic conditions, and pregnancy or breastfeeding all rule treatment out. Women planning to conceive are advised to stop treatment and allow a washout period before trying. These are not minor caveats, they are the clinical reasons why a real assessment, not a checkbox, is required before any script is written.

If you are unsure where you stand, the Wegovy overview page summarises the licensed eligibility criteria in plain terms, or the NHS BMI calculator gives you a starting number to bring to your consultation.

Where does a legitimate Wegovy script come from?

This is the decision that trips most people up. There are broadly three routes: your GP, an NHS specialist service, or a regulated private clinic or pharmacy. On the NHS, NICE recommends Wegovy only within specialist weight management services, and waiting times can be long. From April 2026 some GP practices may also prescribe under updated contract arrangements, but this varies considerably by area.

A private route through a GPhC-registered prescriber sidesteps the waiting list and does not require a GP referral, but the clinical standard must be identical. The MHRA has been clear that counterfeit semaglutide pens (some containing insulin rather than semaglutide) have reached people who bought from sellers offering the medicine without a proper clinical assessment. You can check whether any online pharmacy is properly registered at the GPhC pharmacy register; it takes about thirty seconds and tells you immediately whether the service is regulated. Sellers who offer a Wegovy pen without a prescription are operating outside the law.

At a reputable service, the process runs in a set sequence: you complete a clinical history, a prescriber reviews it personally the same day, your identity and weight are verified, and the script is issued only if treatment is clinically appropriate. No script is issued first and questions asked later.

What changes when you actually start on a Wegovy script?

The titration schedule is gradual by design. Treatment opens at 0.25 mg weekly, a dose chosen to help your body adjust, not one expected to produce significant weight change. The prescriber then steps the dose up roughly every four weeks, through 0.5 mg, 1.0 mg and 1.7 mg, towards the 2.4 mg maintenance dose. The MHRA approved a 7.2 mg pen in April 2026 for adults with a BMI of 30 or above, representing the new maximum for those who progress to it under clinical supervision.

Side effects at each step are mostly gastrointestinal: nausea, loose stools, reflux and reduced appetite are the most commonly reported, and they tend to be most noticeable in the first week or two after a dose increase. Keeping the pen in the same spot in the fridge door and injecting on the same day each week helps turn the routine into something unremarkable fairly quickly. For the full side-effect picture, the Wegovy SmPC on the eMC is the definitive reference, it is publicly available and worth reading before your first injection.

Women taking the oral contraceptive pill should be aware that GLP-1 medicines can slow gastric emptying and potentially affect pill absorption; your prescriber can advise on whether an additional method is sensible during titration. Anyone due to have surgery should tell their anaesthetist they are on semaglutide. These are conversations to have at the consultation stage, not after the script has been issued. If you want to understand the broader pharmacology of semaglutide before that conversation, that page covers the mechanism in plain language.

How much does a Wegovy script cost, and what does that include?

A private Wegovy prescription is not just the pen. It should include the clinical assessment, the prescription itself, dispensing, and ongoing support if side effects arise, and it is worth asking each provider which of those are bundled and which trigger an extra charge. Some services separate out consultation fees or charge for dose-review calls; others include aftercare as standard. A UK price comparison for Wegovy sets out what different providers typically charge and what those prices do and do not include, which is useful context before committing to a service.

The honest framing is this: for a prescription medicine, the cheapest listing is the wrong question to start with. The right question is whether the service behind it is properly regulated, whether a real prescriber reviews your notes, and whether someone is available if things go wrong at week three. That is the standard to hold any provider to, including us. If you would like to read a plain-language description of what Wegovy is and how it works before making any decisions, that page covers the essentials clearly. Equally, if the ongoing cost and structure matter to you, our Wegovy subscription page explains how a rolling plan is set up and what it covers month to month. When you are ready to explore whether Wegovy is right for your situation, speaking to our prescribers is the next step, the consultation is free, and a GPhC-registered prescriber reads every response personally.
