What actually comes in a Wegovy starter kit?

What is physically included in a Wegovy starter kit?

The term "Wegovy starter kit" usually refers to the first month's supply of semaglutide at the 0.25mg starting dose, packaged with the materials you need to use it safely. Inside the box you'll typically find the pre-filled KwikPen, a Patient Information Leaflet, and needles. Some supplies arrive with needles already fitted; others include them separately in a sealed foil pack. Either way, the leaflet tells you exactly what's in your particular batch.

The pen itself holds four doses, one for each week of the month. You dial to your dose, press the button against the injection site, and hold for a count of ten. Injection sites are the abdomen, thigh or upper arm; rotating between them each week helps avoid local irritation. For a detailed walkthrough of the process before your first pen arrives, the guide on how to start Wegovy covers the practicalities step by step.

One thing worth knowing: the 0.25mg starting strength is a tolerability dose. Its job is to introduce semaglutide to your system gradually, reducing the chance of nausea in the early weeks. Your prescriber will guide any subsequent increases, the titration schedule is not something to adjust yourself, and the Patient Information Leaflet sets out the licensed steps clearly. The getting started with Wegovy page has more on what to expect during that adjustment period.

Does the starter kit include a test kit or a special beginner's pack?

Some readers searching for a "semaglutide starter kit" are wondering whether there's a separate diagnostic or test kit involved, there isn't. Wegovy treatment begins with the 0.25mg pen. What varies between providers is what's included around it: some package the first pen with written guidance, some provide a nurse call, some provide nothing beyond the medicine itself.

There is a related product sometimes called a semaglutide test kit, which relates to verifying the authenticity of a medicine rather than starting treatment. Given the volume of counterfeit pens that have entered the UK market (the MHRA seized around 20 million doses of illegally traded weight-loss medicines worth approximately £45 million in 2025) understanding how to verify what you've received matters. The MHRA's Yellow Card scheme is also the place to report any pen that looks or behaves unexpectedly.

A legitimate Wegovy starter pack from a GPhC-registered pharmacy will always arrive as part of a prescription issued by a qualified prescriber. You can read more about what a Wegovy starter pack includes and how it differs from later maintenance packs, including the higher-dose options now available following the MHRA's approval of the 7.2mg pen in April 2026.

Who can receive a Wegovy starter kit on a private prescription?

Wegovy is licensed for adults with a BMI of 30 or above, or 27 or above where a weight-related condition is present, things like high blood pressure, high cholesterol, obstructive sleep apnoea or type 2 diabetes. Lower BMI thresholds apply for certain ethnic backgrounds under UK guidance, typically 2.5 kg/m² below the standard figures. A BMI figure alone doesn't decide anything; a prescriber weighs the full clinical picture.

Wegovy is not recommended during pregnancy, while breastfeeding, or for anyone trying to conceive. It is not licensed for under-18s. If you have a history of pancreatitis, medullary thyroid carcinoma or certain gastrointestinal conditions, that's a conversation for your prescriber before treatment begins. The NHS has useful background on semaglutide on its semaglutide medicines page, including contraindications presented in patient-friendly language.

On the NHS, access to Wegovy is currently through specialist weight management services under NICE guidance, with waiting lists that can be lengthy. A private prescription through a regulated online pharmacy is the route for people who don't meet the current NHS criteria or prefer not to wait. You can explore what that involves on the Wegovy overview page, or compare it with other licensed treatments on the weight-loss treatments overview.

What side effects should you watch for in the first few weeks?

The most common early side effects with semaglutide are gastrointestinal: nausea, loose stools, constipation, indigestion and burping. They tend to be most noticeable in the days after the first injection or following a dose increase, and most people find they settle within one to two weeks as the body adjusts. Eating smaller portions, staying well hydrated and avoiding very fatty meals in the early weeks all help.

Less common but more serious: acute pancreatitis is a known, infrequent risk with GLP-1 medicines. Severe stomach pain that spreads to the back (with or without vomiting) needs urgent medical attention, not a wait-and-see approach. The MHRA highlighted this in a January 2026 Drug Safety Update. Gallbladder symptoms, signs of dehydration from prolonged GI illness and allergic reactions are also reasons to seek help promptly rather than push through.
