Why choose Wegovy for weight loss?

Wegovy is a clinically proven weight loss treatment. On average, Wegovy patients lose 15% of their body weight over 52 weeks.¹

  • Controls appetite
  • Slows digestion
  • Keeps you feeling full for longer

If you've tried diet and exercise but still can't lose weight, the revolutionary Wegovy medication might be right for you.


Wegovy is a weight loss injection for people living with obesity. Taken once per week over 52 weeks, it's clinically proven to reduce body weight by 15% on average.¹


Wegovy doesn't work for everyone – and it's not meant as a replacement for diet and exercise. But if you're eligible for the programme, you'll get tailored advice and guidance from SemaPen's clinical experts.


Start with a digital consultation on the SemaPen app. You'll know right away if Wegovy is a fit for you. If it isn't, our clinical team may suggest another approach, like Mounjaro or our drug-free SemaHealth programme. Whatever the recommendation, you'll have direct access to weight loss experts and practical support from our app to help you lose weight and improve your health.

How to get Wegovy on private prescription

Wegovy works for around 95% of patients – but it's not suitable for everyone. That's why it's important to have a consultation with a medical professional before you buy Wegovy online in the UK.

1. Get started with our app

Begin with a quick digital consultation designed by leading weight-loss experts. It lets you know right away if Wegovy is suitable for you. If not, we may recommend a different weight loss programme that better suits your needs.

How to take Wegovy

Taking Wegovy: a step-by-step guide

1. Do a visual check

Take the lid off your Wegovy pen and make sure the liquid is clear and colourless.

2. Attach the needle

Pull back the tab on the needle and then screw it onto the pen. Remove the top sheath and inner sheath.

3. Check the flow

Dial up to the flow marker (∙ ∙). Hold the pen upright and press the button until liquid squirts out.

4. Dial up to your dose

Turn the dial until it reaches your required dose (it will lock at this setting).

5. Inject the needle

Insert the needle into the soft part of your belly. Press the button and wait for 10 seconds.

6. Wait a week and repeat

Each pen has enough for four weekly doses. It's a good idea to rotate the injection site each time.

Wegovy dosage chart

You take Wegovy once a week by injecting it yourself at home. You can take it at any time of day, with or without meals. However, it's important to take it on the same day each week.


When you first purchase Wegovy online through SemaPen or get an NHS prescription, you'll receive a 0.25mg pen with enough for four weekly doses. This is your starting dose.


Your dose increases each month until it reaches 2.4mg. This is your maintenance (maximum) dose. Most patients continue taking this dose for the duration of their treatment.


Remember that your Wegovy medication programme is a marathon, not a sprint. That's why it's important to step up the dose gradually – it takes time for your body to get used to the medication.


The good news is that you don't have to remember to order your next pen. SemaPen's subscription service means we take care of dates and dosages for you.

What are the possible side effects of Wegovy medication?

All medications can cause side effects. A side effect is any unwanted result from taking a medication.


In Wegovy clinical trials, the most common side effects were nausea and stomach problems, including tummy pain, diarrhoea and vomiting. A fair few patients also experienced headaches.


You might experience these side effects, too. However, they're typically mild and can be managed at home with simple remedies or over-the-counter drugs.


More serious side effects are rare, though they do happen from time to time.


We haven't listed all the possible side effects here. For more information on side effects and how to manage them, read our guide to the side effects of weight loss drugs.
