Overview

Ozempic (semaglutide) is a once-weekly injectable treatment licensed for type 2 diabetes. It contains semaglutide, a GLP-1 receptor agonist that works by lowering blood sugar and supporting healthy weight management in people with type 2 diabetes. It slows digestion, reduces appetite, and helps the body regulate insulin more effectively.

Although Ozempic is primarily prescribed for diabetes, many patients taking it also notice a reduction in weight. This is because semaglutide works on the same appetite and satiety pathways in the brain that are targeted in newer weight loss medicines.

In fact, semaglutide is also the active ingredient in Wegovy, which is licensed specifically for weight management. While Ozempic and Wegovy are prescribed for different conditions, they both work in a very similar way inside the body.

At SwiftMedi, your treatment is supplied after a secure online consultation with a UK-registered prescriber, dispensed from our UK-regulated pharmacy, and delivered quickly and discreetly to your door.

Administration: Injected once a week under the skin (abdomen, thigh, or upper arm).


Dosing schedule: Usually starts at 0.25mg weekly, gradually increasing under prescriber guidance.


Ease of use: Pre-filled pens make self-injection straightforward and safe.


Duration: Ozempic is intended for long-term use in type 2 diabetes management.

Frequently asked questions

  • What is Ozempic and what is it used for?

    Ozempic contains semaglutide and is licensed in the UK for treating type 2 diabetes. It helps lower blood sugar and reduce health risks. Although not licensed for weight loss, some people may be assessed for suitability as part of an individualised weight loss plan.

  • Does Ozempic help with weight loss?

    Ozempic can support weight loss by reducing hunger and helping you feel full sooner. This makes it easier to eat smaller meals and maintain routines. Weight loss benefits are well recognised, but using Ozempic for this purpose is considered off-label in the UK. 

  • Who can use Ozempic for weight management?

    Some adults with obesity or overweight and health risks may be considered for off-label Ozempic, but suitability depends on a clinical review. Your clinician will check your BMI, medical history and medications to decide if it is safe and appropriate.

  • How do I take Ozempic and what dose do I start on?

    Ozempic is injected once weekly into the skin of your tummy, thigh or upper arm. Most people start on 0.25 mg weekly for four weeks, then gradually increase the dose depending on response and tolerance. Your prescriber will guide you through safe pen use.

  • What side effects can Ozempic cause?

    Common side effects include nausea, indigestion, constipation, diarrhoea and reduced appetite. These often improve as your body adjusts to treatment. A prescriber will check for any medical conditions or medications that may increase your risk of side effects.

  • How long does Ozempic take to work?

    Many people notice changes in appetite within the first few weeks, with weight-related benefits and blood sugar improvements developing gradually over several months. Steady routines and balanced meals support better long-term results.

  • Who should avoid using Ozempic?

    Ozempic is not suitable for people who are pregnant, breastfeeding, under 18 or have certain conditions such as severe stomach disease or a personal or family history of thyroid cancer. Your prescriber will confirm safety before treatment. 

  • Why is Ozempic sometimes used off-label for weight loss?

    Ozempic is licensed for diabetes but contains the same active ingredient used in licensed weight loss treatments. Because it reduces appetite and supports calorie control, some clinicians may prescribe it off-label when appropriate. This requires a full safety assessment.

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

    Yes, some people without diabetes may be considered for off-label Ozempic if they meet the BMI and health-risk criteria. Your prescriber checks everything carefully to ensure this is safe and clinically appropriate.

  • Do I need a specific diet while taking Ozempic?

    You don’t need a strict diet, but smaller balanced meals help reduce nausea and support better results. Choosing lean protein, plenty of fibre and limiting large or greasy meals can improve comfort during treatment.

  • Is Ozempic safe for long-term use?

    Evidence shows Ozempic is generally safe for long-term use when monitored. Regular check-ins help review progress, adjust doses and manage any side effects. Your clinician will guide how long it should be used. 

  • Can I drink alcohol while taking Ozempic?

    Yes, but alcohol may worsen nausea or digestive symptoms, particularly early on. If you have diabetes, alcohol can also increase the risk of low blood sugar, so moderation is important.

  • What should I do if I miss a dose of Ozempic?

    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 it and take your next dose on your normal day. 

  • Can I take Ozempic during pregnancy or breastfeeding?

    No. Ozempic should not be used during pregnancy or breastfeeding, and you should stop it before trying to conceive. Speak to your clinician for safer alternatives if you are planning pregnancy.
