What is Wegovy and how does it work?

Wegovy contains semaglutide, which copies a natural gut hormone (GLP-1) that helps regulate appetite. It is injected once a week with a pre-filled pen. In the UK it is licensed for adults with a BMI of 30 or more, or a BMI of 27 to under 30 with at least one weight-related health condition such as high blood pressure or type 2 diabetes. It is also licensed to reduce the risk of heart attack and stroke in some adults with established heart disease. We supply Wegovy to adults for weight management.

Wegovy works in three ways. It acts on the parts of the brain that control appetite, so you feel less hungry. It slows how quickly your stomach empties, so you feel full for longer. And it helps your body release insulin when your blood sugar rises. Wegovy is used alongside a reduced-calorie diet and more physical activity.

Wegovy doses: how titration works

Treatment starts low and steps up every four weeks so your body can adjust. Never change your dose without your prescriber.

If side effects are troublesome, your prescriber may keep you on a dose for longer or step you back down. Some people stay on a lower dose if it is working for them.

Wegovy 7.2 mg: the higher dose

In January 2026 the MHRA approved a higher 7.2 mg weekly dose for adults with a BMI of 30 or more. It can be considered after at least four weeks on 2.4 mg, and it is not used for people with a BMI under 30 or for heart-risk reduction. We supply it only when our prescriber confirms it is appropriate for you, so please tell us your current weight and how long you have been on 2.4 mg when you order.

Wegovy 7.2 mg comes as a single-dose pen: one pen is one injection, used once a week and then thrown away, and each box holds four pens. This is different from the multi-dose pens used for the lower strengths.

Is Wegovy 7.2 mg right for me?

• Who it is for: adults with a BMI of 30 or more who have been on 2.4 mg for at least 4 weeks and are tolerating it.
• Who it is not for: anyone with a BMI under 30, anyone using Wegovy only to lower heart risk, and under-18s.
• Moving up from 2.4 mg: only step up when your prescriber agrees. Side effects such as nausea can return after a dose increase, so tell us if 2.4 mg is still causing problems.
• How we check: before dispatching 7.2 mg we confirm your current weight and BMI and how long you have been on 2.4 mg. If you got 2.4 mg elsewhere, we may ask for proof of your previous supply, such as a dispensing label or order confirmation.

Wegovy prices

For 0.25 mg to 2.4 mg, each pen contains four weekly doses, so one pen lasts four weeks. Wegovy 7.2 mg comes as a box of four single-dose pens, which also lasts four weeks.

How to use the Wegovy pen

• Inject once a week, on the same day each week, at any time of day, with or without food.
• Inject under the skin of your tummy, thigh or upper arm, and use a new needle for every injection.
• If you miss a dose, take it as soon as you remember if it is within 5 days. If more than 5 days have passed, skip it and take the next dose on your usual day. Never take two doses to make up.
• If you have missed more than one dose, speak to us before restarting, because you may need to restart at a lower dose.

How to store Wegovy

Keep new pens in the fridge (2°C to 8°C), away from the cooling element, and never freeze them. Once you start a multi-dose pen (0.25 mg to 2.4 mg), you can keep it in the fridge or below 30°C for up to 6 weeks. Keep the cap on to protect it from light. Wegovy 7.2 mg single-dose pens can be kept out of the fridge, below 30°C, for up to 28 days; throw away any pen that has been out of the fridge for longer. Don't use a pen that has been frozen.

Wegovy pen, Wegovy Pill or Mounjaro?

The Wegovy Pill contains the same medicine, semaglutide, as a once-daily tablet taken on an empty stomach. Mounjaro is a different medicine, tirzepatide, also injected once a week. Foundayo (orforglipron) is a once-daily tablet with no food restrictions. Which suits you depends on your health, other medicines and preferences, and your prescriber will advise.
