An overview

What is Wegovy?

Proven weight loss medication

Wegovy is an easy, once-weekly injection that helps reduce your appetite and supports long-term weight loss. Wegovy is popular for also offering health and lifestyle benefits.

How it works

The active ingredient in Wegovy is semaglutide. It works by increasing levels of a hormone called GLP-1. Increasing GLP-1 levels slows down digestion and stomach emptying. This affects your appetite because you feel fuller for longer, which means you eat less.

Wegovy and Ozempic

Wegovy is the same as Ozempic, they both contain semaglutide. However, only Wegovy is licensed as a weight loss treatment. Ozempic is licensed instead as a treatment for type 2 diabetes. Wegovy is available in more dosages and higher strengths than Ozempic.

Protects the heart and kidneys

Wegovy has been approved to reduce the risk of major cardiovascular events. A recent study shows that Wegovy 20% reduced the risk of heart attack and stroke¹. It also helps lower the risk of serious kidney problems in type 2 diabetes with kidney disease².

Oral contraceptives

If you’re using oral contraceptives, it’s good to know that clinical tests confirm that Wegovy does not affect oral contraceptives, unlike some other weight loss medications.

Clinical results

How effective is Wegovy?

Clinical studies show that with Wegovy, you can lose up to 17% of your body weight in 15 months³, and up to 21% with the upcoming 7.2 mg dose (step up)⁴.

Featured reviews review
  • I used wegovy first time yesterday and I have to say It started
    working few hours after first injection. First of all I started
    feeling tired and I had nausea, my mouth became dry. I had to drink a
    lot of water and I wasn't bothered with any food. All cravings
    gone. So far ,I'm so happy with wegovy, can't wait till next week to
    see the results.

    Anna H
  • Having tried a few of these injection weight loss drugs and tablet
    form weight loss drugs I find Wegovy to be the best. The side effects
    have been very minimal for me in comparison to ozempic and the drug
    feels cleaner in your body. I feel great and I’m losing weight at a
    healthy pace while still enjoying meals and having energy and no
    sickness.

    Remmi P
  • Only been using Wegovy for 4 days but showing a loss of weight
    already. Definitely curbs my appetite. I don't want to graze or
    drink alcohol. Previously I had a couple of brandies every night. I
    suffer from anxiety. No longer want or feel the need to drink
    alcohol. I'm very impressed.

    Jeanette
  • A bit early to review totally but by day 2 I’ve lost 4 lbs. No
    unpleasant side effects as such and it has worked wonders taking away
    my appetite for food and alcohol. Still ate healthily and found myself
    with more energy.

    Wendy
  • Wegovy works incredibly well. It is not a quick fix to instant
    slimness but enables you to lose weight - not too quickly but at a
    rate where the pounds gradually fall off, and you don't feel hungry in
    the process.

    Mrs Anne S
  • Its my first week, and I must say product is great. Just follow
    instruction and everything is alright. And definitively you are not
    hungry and not craving for any food, what your go before injection.

More information about Wegovy

Starting on Wegovy

Can I switch from Mounjaro to Wegovy?

Yes, if you are currently taking Mounjaro, you can switch to Wegovy. You can choose a similar dose or start again on the lowest dose of Wegovy. For example, if you are currently using the 5 mg dose of Mounjaro, you can take the 0.5 mg dose or go up to the 1 mg dose of Wegovy. You must wait at least 7 days after your last dose of Mounjaro before starting Wegovy.

Can I start Wegovy at 0.5 mg?

No, you must start on the 0.25 mg dose of Wegovy if it is your first time or you have not used it in a while. This is to ensure your body can get used to the medicine and minimise side effects.

Do I have to increase the Wegovy dose?

You do not have to increase the dose of Wegovy each time. The dose is increased gradually to allow your body time to adjust, and for some this may take longer. Everyone’s tolerance is different — some patients remain on lower doses, while others move up to the maximum. Our clinicians and nutritionist support help guide you to the right maintenance dose for your body.

Taking Wegovy

Does it hurt to inject Wegovy?

You should experience little to no pain if you inject Wegovy correctly. It should feel like a small pinching sensation as the needle goes into the skin. However, you may experience an injection site reaction after you use Wegovy, such as redness, swelling or itching. Make sure you rotate the injection spot each time and clean it before injecting to limit skin reactions.

What are the side effects?

Like all prescription medicines, Wegovy can cause some side effects, although not everyone gets them. Common side effects include diarrhoea, dizziness, tiredness, feeling sick and being sick. These common side effects should go away on their own after your body gets used to the medicine. If your side effects do continue, you may need to stay on your current dose a bit longer. If you experience any serious side effects, such as severe abdominal pain, stop taking it.

How quickly does Wegovy work?

You should start to notice a change in your appetite within the first week. In terms of weight loss, you should notice after 12 weeks a 6% weight loss. You should expect significant results after 15 months, with patients losing at least 17% of their body weight ³.

When do I stop taking Wegovy?

You can usually continue using Wegovy at the maintenance dose until you have reached your goal weight and feel confident enough to stop using it, unless your BMI goes below 20. This allows you to continue developing your lifestyle habits at your new weight, ensuring ultimate success as you transition from treatment.

Lifestyle habits

Can I drink alcohol on Wegovy?

Yes, but in moderation. Alcohol can make side effects like nausea worse and slow down digestion. Alcohol can also damage your weight loss efforts, as it is high in calories and sugar with little nutritional value.

How much water should I drink on Wegovy?

A good target is around 2 litres daily. Staying hydrated supports digestion, prevents constipation, and reduces side effects. Herbal teas, diluted squash, or sparkling water all count.

Can I exercise on Wegovy?

Yes — in fact, it’s recommended. Exercise not only boosts weight loss but also helps preserve muscle mass and improve mood. If you’re new to exercise, start small: brisk walking, swimming, yoga, or light weights. As you feel stronger, you can build up gradually.
