Wegovy Overview

Wegovy is one of the most trusted and clinically proven weight loss injections available today. Powered by semaglutide (the same ingredient found in Ozempic), Wegovy works by reducing appetite, slowing digestion, and helping you feel fuller for longer. This makes it far easier to manage cravings, cut calories, and stay on track with your weight loss goals.

In clinical studies, patients using Wegovy lost an average of 10–15% of their body weight, with many also reporting better energy, improved health, and greater confidence in daily life. Unlike daily treatments such as Saxenda, Wegovy is taken just once a week with a simple pre-filled pen, making it convenient and easy to fit into your routine.

For patients seeking a clinically proven, cheaper alternative to newer treatments like Mounjaro, Wegovy offers the perfect balance of effectiveness, safety, and convenience.

Available from SwiftMedi following a secure online consultation with a UK-registered prescriber, your treatment will be dispensed from our UK-regulated pharmacy and delivered quickly and discreetly to your door.

Treatment Description

Administration: Wegovy is taken as a once-weekly injection under the skin of the abdomen, thigh or upper arm.


Dosing schedule: Treatment begins at a lower dose, which is gradually increased over several months until the full maintenance dose is reached.


Ease of use: Pre-filled pens are designed to make self-administration at home simple and safe.

Frequently Asked Questions

Below are some of the more common questions we hear from customers about shopping with Swiftmedi.

  • What is Wegovy, and what is it used for?

    Wegovy is a once-weekly injection containing semaglutide. It is used to support weight loss in adults with obesity, or overweight with related health risks. Treatment is prescribed following a full clinical assessment and works alongside lifestyle changes to help support long-term weight management.

  • How does Wegovy help with weight loss?

    Wegovy mimics a natural hormone involved in appetite regulation, helping you feel fuller sooner and reducing hunger. This can make it easier to eat smaller portions and maintain a calorie deficit, supporting gradual and sustainable weight loss when combined with healthy habits.

  • Who can use Wegovy for weight management?

    Wegovy is usually recommended for adults with a BMI over 30, or over 27 if they have a weight-related condition such as high blood pressure, diabetes or high cholesterol. A prescriber will review your health history, current medicines and safety considerations before treatment begins.

  • How do I take Wegovy, and what dose do I start on?

    Wegovy is injected once a week under the skin of the abdomen, thigh or upper arm. Most people start on a 0.25 mg dose for four weeks, with the dose increased gradually to reduce the likelihood of side effects such as nausea. It should be taken on the same day each week.

  • What side effects can Wegovy cause?

    Common Wegovy side effects include nausea, constipation, diarrhoea, tiredness and reduced appetite. These often improve as your body adjusts to treatment. Your clinician will review your medical history to ensure Wegovy is safe for you and to identify any factors that may increase the risk of side effects.

  • How long does Wegovy take to work?

    Many people notice changes in appetite within the first few weeks, with visible weight loss typically developing over several months. Results are best when Wegovy is combined with regular meals, balanced nutrition and supportive lifestyle changes.

  • Who should not use Wegovy?

    Wegovy is not suitable if you are pregnant, breastfeeding, under 18, or have certain medical conditions, including severe stomach disorders or a personal or family history of thyroid cancer. Your prescriber will carefully assess your clinical background before approving treatment.

  • Can I use Wegovy if I don’t have diabetes?

    Yes. Wegovy is licensed for weight management in adults without diabetes, provided they meet the relevant BMI and health-risk criteria. Your prescriber will confirm that it is safe, particularly if you have long-term conditions or take other medicines.

  • What foods help reduce side effects on Wegovy?

    Eating smaller meals, including lean protein, and choosing fibre-rich foods can help reduce nausea and support digestion. Avoiding large, greasy or spicy meals may also help, especially during dose increases.

  • Is Wegovy safe for long-term use?

    Current evidence shows Wegovy is safe for long-term use when monitored by a clinician. Regular reviews help track progress, manage side effects, and ensure the dose remains appropriate as your weight and health change.

  • Can I drink alcohol while taking Wegovy?

    Yes, but alcohol may worsen nausea or stomach discomfort, particularly in the early stages of treatment. If you have diabetes, alcohol may also increase the risk of low blood sugar, so moderation is advised.

  • What should I do if I miss a Wegovy dose?

    If you remember within five days of your usual dosing day, take the missed dose as soon as possible. If more than five days have passed, skip the missed dose and take your next injection on your regular day.

  • Can I use Wegovy during pregnancy or breastfeeding?

    Wegovy is not recommended during pregnancy or breastfeeding, and should be stopped before trying to conceive. Your clinician can advise on alternative options if you are planning a pregnancy.

  • Can I buy Wegovy online in the UK?

    Yes, but only from a regulated UK online pharmacy following a full clinical consultation. A prescriber must review your medical history, current medicines and eligibility before Wegovy can be supplied safely.

  • Wegovy vs Mounjaro: what’s the difference?

    Wegovy and Mounjaro are both popular once-weekly prescription injections for weight loss, but they contain different active ingredients. Wegovy uses semaglutide, which targets appetite regulation, while Mounjaro contains tirzepatide, which acts on two hormones involved in appetite and blood sugar control.

    Which option is most suitable for you depends on your health history, goals and how you respond to treatment. Wegovy is usually available at a lower price than Mounjaro, which can be an important factor to consider. A prescriber will assess these factors and recommend the best choice for you.
