Meta Advertising Policy for Medical Weight Loss Ads: Guidelines (October 2026)

01 · The core answer

Can you advertise weight loss medicine on Meta?

You can advertise a legitimate weight-loss service on Meta, but you cannot advertise a prescription-only medicine by name to the public. That is the line that matters most, and it is the one most weight-loss clinics trip over. A GLP-1 or GIP/GLP-1 injection is a prescription-only medicine, so ads that name the product, show the pen, or invite people to buy it fall on the wrong side of both Meta's rules and UK medicines advertising law.

What remains open is education and service-led advertising. You can talk about a clinic, a consultation, a support programme or general healthy-weight information, as long as the creative does not steer the reader towards a specific prescription medicine. Our guide to how GLP-1 ads are treated goes deeper on the wording side.

If you are a patient rather than an advertiser, the practical point is different: a legitimate supplier will never need to reach you through a glossy social ad. Any seller offering to supply a prescription medicine without a consultation or prescription is a red flag, whatever platform it appears on.

02 · What to do next

The decisions advertisers actually face

Most advertisers are choosing between three routes: educational content, service promotion, and lead generation. Educational content is the safest, because it informs without selling a named medicine. Service promotion works when it describes how a consultation or clinic operates rather than what drug you will receive. Lead generation forms are allowed in principle, but the landing page and the form must also be compliant, because Meta reviews the destination as well as the ad.

If you are researching treatment rather than advertising, you can go straight to the Mounjaro pen and consultation, where the standard price starts at £169.99 per month for the 2.5mg starting pen (checked 10 October 2026).

03 · Meta's health rules

What Meta's health and wellness policies cover

Meta's health and wellness rules sit across several parts of its Advertising Standards, and weight-loss content touches more of them than most advertisers expect. The themes are consistent: no promotion of prescription drugs to consumers where the law forbids it, no unrealistic or exaggerated outcomes, no content that implies or asserts personal attributes, and extra care around audiences who may be vulnerable.

Meta groups the relevant restrictions under a handful of headings. They include prohibited and restricted content such as unsafe substances and misleading claims, personal health and appearance rules, and the age-targeting requirement for weight-loss products and services. Because Meta reorganises these pages periodically, a policy you read last year may have moved or been reworded.

Two practical consequences follow. First, a compliant ad needs a compliant landing page, because reviewers follow the click. Second, a rejection is rarely about a single word. It is usually the combination of imagery, headline, targeting and destination that tips an ad over.

04 · Prescription medicine ban

Why prescription weight-loss jabs cannot be advertised

Prescription-only medicines cannot be advertised to the public, and weight-loss injections are prescription-only. In the UK this follows from medicines regulation: advertising to consumers is limited to non-prescription products, while information for healthcare professionals is treated separately. Meta's policy aligns with this by prohibiting consumer promotion of prescription drugs in places where the law bars it.

The medicines themselves explain why the rule matters. Mounjaro, for instance, is a once-weekly injectable prescription medicine licensed in the UK for weight management in adults and for type 2 diabetes, and it is used alongside a reduced-calorie diet and increased physical activity.¹ It is supplied only after an online consultation reviewed by a GPhC-registered prescriber. The decision to prescribe belongs to a clinician who weighs suitability, not to an advert.

Ozempic is semaglutide licensed for type 2 diabetes. It is not a UK weight-loss medicine, and a compliant public ad for it does not exist. Anything that appears to sell it or similar injections directly through a social ad deserves caution. Patients should read the patient information leaflet and speak to a prescriber before starting any medicine.¹³

For advertisers, the sensible workaround is not clever phrasing. Euphemisms such as hinting at a named product with emojis, code words or a pen image are treated by reviewers and regulators as the same promotion. Promote the service, not the drug.

05 · Imagery and claims

Before-and-after images, claims and flagged words

Before-and-after visuals are the most frequently rejected creative in weight-loss advertising. Meta treats literal split-screen transformations as a problem, and it also looks at implied transformations, such as a product placed beside a fit model or a tape measure draped over a stomach. The concern is that the image suggests a typical or assured outcome and plays on how people feel about their bodies.

Words matter as well, though there is no single banned-word list. Reviewers, human and automated, respond to patterns. Phrases that address the viewer's body directly, such as asking whether they are overweight, tend to trip the personal attributes rules. Dramatic claims about fast or effortless results trip the misleading-claims rules. Superlatives and promises of specific outcomes are risky for the same reason, and under UK advertising codes they can also breach the ASA's rules on health and weight-control claims.

Safer habits for copy and creative:

• Describe what the service does, for example a clinician-led assessment, rather than what the viewer will look like afterwards.
• Avoid second-person statements about weight, shape or size.
• Do not name or picture a prescription medicine, pen or packaging.
• Keep any health statement accurate and tied to a recognised source.

Supplements deserve a separate warning. Low-cost supplements marketed as natural alternatives to prescription injections, with dramatic weight-loss claims, carry no clinical oversight and attract both policy rejections and regulator attention. Dosing is not standardised, and their marketing should never borrow the language of licensed medicines.

06 · Targeting rules

Age targeting and audience restrictions

Weight-loss ads must not be shown to minors. Meta requires advertisers promoting weight-loss products, services or supplements to restrict the audience to adults, and it applies the same logic to wider appearance-related content. Set the age floor explicitly in your audience settings rather than relying on defaults, and check that lookalike or broad audiences do not widen it.

There are further audience considerations. Interest targeting based on sensitive health conditions is limited, and Meta has reduced the detailed targeting options linked to health. Even where an option exists, using it to single out people because of a health condition or body concern is exactly the kind of personal attributes problem the policy is built to prevent. Broad adult targeting with a service-led message is both more compliant and, often, just as effective.

Eating disorders are the reason these rules exist. A person with a history of disordered eating is more vulnerable to weight-loss messaging, and that is why regulators and platforms act cautiously. Responsible clinics build the same caution into their service: a prescriber review looks at suitability and does not simply score a form.

07 · Common rejection reasons

Why Facebook rejects health ads and mistakes to avoid

A valid reason for rejection is any breach of Meta's Advertising Standards, and in health the usual causes are predictable. Most rejected weight-loss ads fall into a short list of mistakes.

• Naming a prescription product. Mentioning a brand or generic prescription medicine in the headline, text, image or landing page.
• Personal attributes. Copy that asserts or implies something about the viewer's body, weight or health.
• Before-and-after or implied transformation imagery. Including cropped photos, measuring tapes and side-by-side layouts.
• Unrealistic claims. Promises of rapid, effortless or specific results.
• Landing-page mismatch. An ad that is compliant but sends people to a page that is not.
• Wrong audience settings. Leaving age targeting open for a weight-loss offer.
• Unacceptable business practices. Deceptive offers, misleading pricing, hidden terms or pressure tactics, all of which fall under Meta's rules on misleading or deceptive advertising and are separate from health content.

Repeat violations matter more than a single rejection. Appealing an ad that is genuinely non-compliant tends to waste time, and repeated breaches can lead to account-level restrictions. If you receive a rejection, read the stated reason, change the specific element and resubmit rather than testing variations of the same problem.

Advertisers who want a straightforward template should look at how a regulated service describes itself: who reviews the consultation, how delivery works, what support follows. Those facts are allowed and are what readers want.

08 · UK law and ASA

UK rules that apply alongside Meta's

Meta's policy is only one layer. In the UK, medicines advertising law, the ASA and CAP codes and the MHRA all apply to weight-loss advertising, and passing Meta's review does not make an ad lawful. The ASA has authority over non-broadcast advertising, including social media, and it regularly rules against ads for prescription-only weight-loss medicines and against misleading weight-control claims.

The regulatory emphasis is consistent: protect the public from promotion of prescription medicines, and protect patients from unsafe products. The MHRA also issues counterfeit medicine alerts and runs the Yellow Card scheme for reporting suspected side effects, so patients can report problems with any medicine.⁷¹⁹

For pharmacies there is a further point. A registered online pharmacy is listed on the GPhC register, and you can check ours under GPhC registration 9012878. Advertisers should expect that regulators will look at who stands behind an ad, not only what it says.

If you are weighing NHS and private routes, our page on NHS medical weight loss sets out the current position. NHS access to Mounjaro is being phased in over several years, and the primary-care rollout began in June 2025 with the highest-need groups first.

09 · Compliant ad examples

What a compliant weight-loss ad can look like

A compliant ad describes a legitimate service in plain terms and leaves the prescribing decision to a clinician. A pharmacy might promote a free online consultation reviewed by a GPhC-registered prescriber, explain that treatment is only supplied if it is suitable, and mention that delivery is tracked and discreet. None of that names a prescription medicine or promises an outcome.

Three principles help when drafting:

• Lead with the process. Consultation, review, dispatch and aftercare are facts a reader can verify.
• Keep the destination clean. The landing page can explain treatments in an educational, sourced way for people who have chosen to look, which is different from pushing a product in an ad.
• Be honest about cost and suitability. Say that treatment is for adults who meet the licensed criteria and that results vary.

Cost is where many ads become misleading. Do not quote prices in a way a reader cannot reproduce, and do not imply that a discount is permanent unless it is. Our own pricing is shown live on the product page, so readers always see the current figure instead of a stale ad claim.
