Semaglutide 6mg — the dose step that doesn't exist on a Wegovy pen

Why 6mg comes up, and where the confusion starts

The question makes sense once you know the context. Semaglutide exists in three distinct licensed UK products, each with its own dosing ladder, and none of them includes 6mg. Wegovy injections top out at 2.4mg per week. The new Wegovy tablet (the first oral GLP-1 medicine approved for weight management in the UK) runs up to 25mg daily. Rybelsus tablets sit at 3mg, 7mg and 14mg, but those are strictly for type 2 diabetes, not weight loss.

The 6mg figure most likely enters searches in one of three ways: people misremembering a dose they were told about; content from countries where tirzepatide or other agents are described in milligram totals that coincidentally land near 6; or, occasionally, forum discussion that mixes product names. The semaglutide overview on this site covers all three UK products and how they differ, worth reading if you're trying to orient yourself before a consultation.

One thing worth saying plainly: if a seller is offering you a "6mg semaglutide" pen or vial, that is not a licensed UK product. The MHRA has warned repeatedly about counterfeit weight-loss pens circulating online, and unlicensed products claiming to contain semaglutide are among the most commonly reported concerns, including in specific clinical populations such as those covered by guidance on semaglutide and Prader-Willi syndrome where prescribing restrictions are especially strict. You can check whether any pharmacy offering you these medicines is registered at the GPhC's pharmacy register, it takes under a minute.

What the actual licensed injection schedule looks like at this dose range

To understand why 6mg doesn't exist on the injection pathway, it helps to see how the Wegovy titration is structured. Treatment opens at 0.25mg weekly for four weeks, a dose whose job is settling the digestive system before any therapeutic effect is expected. It then steps to 0.5mg, then 1mg, then 1.7mg, and finally 2.4mg as maintenance. The gap between 1.7mg and 2.4mg is the largest single jump on the schedule, and it's the transition most people notice.

Prescribers can hold patients at any step longer than the standard four weeks if side effects need time to settle. That decision belongs entirely to the clinician, not the patient, not the pharmacy, and not a titration chart found online. If you're on the 1mg weekly dose and wondering whether 6mg is a future step, the short answer is no: 2.4mg is the ceiling on the injection, and the updated MHRA approval of a 7.2mg pen (confirmed April 2026) represents the highest dose now licensed, reachable only through clinical re-assessment.

The oral tablet schedule, approved in June 2026, follows entirely different arithmetic. Its steps (1.5mg, 4mg, 9mg, 25mg) are higher in number because semaglutide absorbs far less efficiently from the gut than from a subcutaneous injection. A 25mg tablet delivers roughly comparable systemic exposure to the 2.4mg injection. So while "9mg semaglutide tablet" is a real licensed step, it is a titration point on the oral path only, distinct from anything on the injection schedule. The weight-loss treatments page outlines both options and explains how a prescriber would discuss which route fits your situation.

What this means if you're deciding between the injection and the tablet

The decision between Wegovy injections and the Wegovy tablet is a clinical one, but the practical factors are worth understanding before you speak to a prescriber. The injection is once weekly and requires refrigeration between 2°C and 8°C; the tablet is once daily, can be stored at room temperature and requires no needles. For anyone who travels frequently or simply prefers not to inject, the tablet removes a real barrier.

On results, the OASIS 4 trial (the phase 3 study that supported the UK tablet approval) reported an average weight reduction of around 13.6% over 64 weeks among participants taking the 25mg tablet, rising to approximately 17% among those who stayed fully adherent to the regimen throughout. The injection at 2.4mg produced around 15% average weight loss in the STEP 1 trial, as documented by the NHS semaglutide medicines page. Neither number is a promise, clinical trial participants follow structured support that most private-prescription patients don't have access to, and individual responses vary considerably.

Cost is another factor. For context on what Wegovy injections typically cost through a private pharmacy in the UK, the Wegovy cost page gives a factual market overview. The tablet was launched into the private market only and has no NICE appraisal yet, so NHS access doesn't currently exist for it. A prescriber at a regulated service like ours can talk through both products at consultation, including which one your health history makes more suitable. That conversation is free at nume, no upfront fee, no obligation, reviewed the same day by a real clinician.

Red flags if you've been told 6mg is available

A few things are worth flagging directly. If a website, social media account or unofficial WhatsApp group is offering you semaglutide at 6mg (in any form) they are not describing a UK-licensed product. That is a serious concern, not a minor technicality. The MHRA's Yellow Card scheme exists partly to collect reports of suspect sellers; reports can be submitted at yellowcard.mhra.gov.uk. Fake pens in circulation have included unlabelled insulin in place of semaglutide, the consequences have required hospital treatment.

A legitimate UK online pharmacy will hold a GPhC registration number you can verify, will require a medical questionnaire reviewed by a named prescriber, and will only issue doses that appear on the licensed schedule for that product. At nume, every prescription is assessed by a GPhC-registered Independent Prescriber before anything is dispensed. The pen that arrives (via DPD, in plain unbranded packaging, tracked to your door) is sourced through the authorised UK supply chain. If the dose on the label doesn't match what the NHS or MHRA documents say is licensed, something is wrong.

If you have questions about your current treatment, or you want to explore Wegovy for the first time with a clear picture of what the licensed schedule actually involves, speaking to a prescriber is the right starting point.
