Had a Wegovy Prescription Rejected? Here's What It Actually Means

The biggest misconception: a rejection means you don't qualify for anything

The most widespread assumption after a Wegovy prescription is declined is that weight-loss medicine simply isn't an option for you. That's rarely accurate. UK prescribers follow the medicine's licensed eligibility criteria, their own clinical judgement, and in NHS settings the additional criteria set by NICE, and these are genuinely different things. A refusal through an NHS pathway, for instance, may reflect the tiered access rules under NICE's technology appraisal TA875 rather than anything permanent about your health profile.

Private prescribers follow the licensed eligibility directly: adults with a BMI of 30 or above, or 27 or above alongside a qualifying weight-related condition such as high blood pressure, type 2 diabetes, or obstructive sleep apnoea. If your rejection came through an NHS referral, the threshold that blocked you there may not apply in a private clinical setting. That doesn't mean every rejection evaporates in a different context (contraindications are real) but it does mean a second opinion, properly conducted, is often worth pursuing.

It's also worth distinguishing between a rejection of Wegovy specifically and a broader clinical concern. A prescriber who flags a contraindication to semaglutide may still be able to discuss an alternative. The short version: one refusal is a data point, not a verdict.

Clinical reasons prescribers decline a Wegovy prescription

Prescribers decline for specific reasons, and knowing them helps you address them directly. The NHS's semaglutide information sets out the key contraindications: a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN2), a history of pancreatitis, certain inflammatory bowel conditions, and pregnancy or breastfeeding. These are hard stops, and a responsible prescriber won't move past them.

Beyond contraindications, the more common reason for a decline is BMI. The licensed threshold for Wegovy is BMI 30 or above, or 27 or above with a qualifying comorbidity. If your BMI sits below 27 without a qualifying condition, semaglutide for weight management isn't currently licensed for you in the UK, and a prescriber who declines on that basis is acting correctly. It can feel frustrating, particularly if you've seen the drug discussed for people who appear similar to you, but the licensing boundary is there for clinical reasons.

Interactions with other medicines are another consideration. Semaglutide slows gastric emptying, which can affect how other oral medicines are absorbed. Some antidiabetic medicines carry a hypoglycaemia risk when combined with semaglutide that requires careful management. A prescriber reviewing your medication list isn't being obstructive; they're doing the job properly. If an interaction was flagged, that conversation is worth having with your GP before trying again.

How a fresh clinical assessment works, and what 'same-day review' actually means

If you've been declined before and want to explore your options again, the process at a regulated online pharmacy like nume starts with a free consultation. You answer a structured clinical questionnaire covering your medical history, current medicines, and weight data. A GPhC-registered Independent Prescriber (a real clinician, not a filtering algorithm) reads your answers personally and reaches a decision the same day.

At our clinical team's level of review, that assessment includes live weight verification on video and photo-ID checks; it's a proper clinical encounter, not a tick-box form. If treatment is approved, your prescription is with our GPhC-registered pharmacy the same day, and your order is dispatched for free next-working-day DPD delivery, a plain, unbranded box, tracked to your door, no indication of contents on the outside.

If the prescriber reaches the same conclusion as before, they'll say so clearly, and you'll have a factual reason to take back to your GP. That clarity has its own value. You can explore the full picture of how Wegovy works and what a consultation covers on our treatment overview, or read about the broader semaglutide evidence base if you want the clinical context before you apply.

For those considering what costs might look like if treatment is approved, the Wegovy pricing guide explains honestly what a legitimate private prescription includes and why headline prices vary so much between providers.

When Wegovy genuinely isn't the right fit, and what else exists

There are situations where a prescriber's decline is both correct and, on reflection, in your interest. If your BMI has fallen below the licensed threshold because of changes you've already made to your diet and activity, that's a positive reason for a different conversation about maintenance. If you have a condition that makes semaglutide genuinely unsuitable, the prescriber is protecting you, not blocking you.

Tirzepatide (Mounjaro), the only dual GIP and GLP-1 receptor agonist licensed for weight management in the UK, has a similar eligibility profile (adults with BMI 30 or above, or 27 or above with a qualifying condition) and may suit people for whom semaglutide has specific contraindications. It isn't a guaranteed alternative, but it's a separate clinical question worth raising. Our weight-loss treatment overview sets out both options side by side so you can go into a consultation with a clearer sense of what to ask.

Side effects during a previous course of semaglutide can also prompt a decline or a patient's own decision to stop. Bloating and stomach discomfort are the most frequently reported GI effects; if that's been your experience, pages on bloating on Wegovy and stomach discomfort during treatment explain what's usually happening and when it settles, which is relevant if you're deciding whether to try again. If you've ever had an injection go wrong, our guide on what to do when you've wasted a Wegovy shot is also worth reading before you restart.
