What is Wegovy, and what is it used for?

Wegovy is a prescription-only, GLP-1 receptor weight loss medication containing Semaglutide as the main ingredient. Injected once weekly, it has shown 15% weight loss over 68 weeks when combined with lifestyle changes.

What is a GLP-1, and how does Wegovy help patients lose weight?

GLP-1 is a naturally occurring hormone responsible for regulating appetite and helping you stay full for a long time. Wegovy mimics the action of GLP-1 and helps your body stay satiated by controlling appetite and reducing cravings.

Studies have shown that eating habits become easier to control when combined with sustained physical activity. Wegovy is effective because it directly acts on appetite pathways, so patients don’t have to rely on willpower alone.

Over time, this change in appetite helps create a sustained calorie deficit—crucial for meaningful weight loss. Step by step, people build consistent routines around food, activity, and sleep—the pillars of long-term weight management.

What are the eligibility criteria for Wegovy?

Wegovy is intended for adults who meet the following criteria:

  • BMI of 30 kg/m² or above
  • Or a BMI of 27 kg/m² or above with at least one weight-related condition such as high blood pressure, high cholesterol, or pre-diabetes

You can buy Wegovy online through The Care Pharmacy with a simple consultation to confirm your suitability. We’ll review your medical history, current medications, and assess any risks to ensure treatment is safe and effective.

What is the dosing schedule for Wegovy?

Wegovy is administered once weekly using a pre-filled pen. The starting dose is 0.25 mg and is gradually increased every four weeks based on your body’s response. This slow titration helps minimise side effects.

Wegovy weight loss injection treatments

In the first few weeks, many people feel full sooner during meals and are less tempted by large portions or late-night snacks. To get the best results, we recommend:

  • Creating a realistic meal plan
  • Staying active with daily movement
  • Following a structured workout schedule
  • Maintaining proper hydration

How does Wegovy cost vary according to the dosage?

Wegovy prices generally increase with the dose. Lower doses are typically more affordable, but they are only used for a short adjustment period.

Most people remain on the 2.4mg weekly injection for long-term use, and that’s where the true cost is reflected.

That’s why The Care Pharmacy offers some of the most affordable prices for Wegovy in the UK—without hidden fees. Whether you’re starting out or on the maintenance dose, we provide competitive pricing across all strengths.

  1. M Vigneswararajah (verified owner) –

    It is not controlling the appadiate and as a result weight reduction is not happning

    • Mohammed Ismail Lakhi –

      Thank you for your message. Appetite control can vary during the early stages of Wegovy treatment, and many patients notice improved effects as the dose is gradually increased. If your current dose is not providing adequate appetite suppression, a clinical review may be needed to assess whether a dose adjustment or alternative approach is appropriate. Please share your current dose, duration of use, and any side effects so our team can advise you safely.

  2. Mariam –

    Excellent product and service. Speedy delivery. Answered all my questions.

How is Wegovy injected into the body?

Wegovy comes as a pre-filled injection pen that you use once a week. It is only for your personal use and should never be shared with anyone else.

Choose the dosing day

  • Pick a day of the week that is convenient for you.
  • You can inject at any time of day, with or without food.
  • Try to stick to the same day every week so it becomes routine.

Use the pen properly

  • Wash your hands and check the pen label to make sure you have the right strength.
  • Inspect the solution. It should be clear and colourless. Do not use if cloudy or contains particles.
  • Remove the cap and attach a new needle (never reuse needles).
  • Prime the pen if required (see leaflet instructions for your device).
  • Pinch the skin at your chosen site and insert the needle at the correct angle.
  • Press and hold the button until the full dose has been delivered.
  • Remove the needle, dispose of it in a sharps bin, and replace the pen cap.

Where to inject Wegovy?

Wegovy is injected just under the skin (subcutaneous injection).

  • You can use the abdomen, thigh, or upper arm.
  • Rotate the injection site each week to prevent soreness or irritation.
  • Avoid injecting into areas that are bruised, tender, red, or hard.

What to do if you missed a dose?

  • If you miss a dose and there are more than 2 days (48 hours) until your next scheduled injection, take the missed dose as soon as possible.
  • If there are less than 2 days until your next dose, skip the missed injection and continue with your regular schedule.
  • Do not take two doses within the same 48-hour period.

Are there any storage instructions for Wegovy?

  • Keep unopened pens in the refrigerator at 2°C to 8°C.
  • Do not freeze. If a pen has been frozen, it must be discarded.
  • Protect from light by storing in the carton until ready to use.
  • Once in use, a pen can be stored at room temperature for a limited time (as stated in the leaflet).
  • Always keep medicines out of the reach of children.

What are the possible side effects of Wegovy?

Most side effects of Wegovy are mild to moderate, especially at the beginning of treatment, and tend to improve as your body adjusts. Because Wegovy works on the digestive system, many of the most common effects are related to the stomach and bowels.

Common side effects

These are the most frequently reported and usually settle with time:

  • Nausea
  • Vomiting
  • Diarrhoea
  • Constipation
  • Stomach pain or bloating
  • Indigestion, reflux, or burping
  • Headache
  • Tiredness or low energy
  • Dizziness
  • Injection site reactions such as redness, swelling, or itching

Less common but important side effects

While rare, some patients may experience more serious reactions that need medical attention:

  • Pancreatitis (inflammation of the pancreas): severe and persistent abdominal pain, often spreading to the back, with or without vomiting
  • Gallbladder problems such as gallstones: pain in the upper right abdomen, fever, or yellowing of the skin/eyes (jaundice)
  • Kidney problems: worsening of existing kidney disease, especially if dehydrated from vomiting/diarrhoea
  • Allergic reactions: rash, itching, swelling of the face, lips, tongue, or throat, difficulty breathing

Will I experience blood sugar changes?

If you use Wegovy alongside medicines for diabetes (particularly insulin or sulfonylureas), your risk of low blood sugar may increase. Symptoms include sweating, shakiness, fast heartbeat, hunger, or confusion. If you experience any of these, seek medical attention immediately.

Tips to manage side effects

  • Eat smaller meals and avoid very fatty or spicy foods to help reduce nausea.
  • Stay hydrated, especially if you experience vomiting or diarrhoea.
  • Give your body time to adjust. Many side effects ease after the first few weeks.
  • Speak to your prescriber if side effects are bothersome or do not settle.

When to seek urgent medical advice?

Stop using Wegovy and get medical help right away if you develop:

  • Severe abdominal pain that does not go away
  • Signs of an allergic reaction (swelling of face/lips/tongue, difficulty breathing)
  • Persistent vomiting or diarrhoea leading to dehydration
  • Sudden changes in vision (especially if you have diabetes)

It is always best to read the patient information leaflet inside your pack to be aware of potential side effects before starting.

What warnings should I be aware of before using Wegovy?

Wegovy is a prescription-only medicine and may not be suitable for everyone. Before starting treatment, we require patients to complete a consultation to assess your health history and ensure this medicine is safe for you.

You should not use Wegovy if you:

  • Are allergic to semaglutide or any of the ingredients in the injection
  • Are pregnant, planning a pregnancy, or breastfeeding
  • Are under 18 years of age

Extra care is needed if you:

  • Have a history of pancreatitis (inflammation of the pancreas)
  • Have gallstones or gallbladder disease
  • Have diabetic retinopathy (eye disease linked to diabetes)
  • Use insulin or sulfonylureas (these may increase the risk of low blood sugar)
  • Have other significant long-term conditions

During treatment, seek urgent medical advice if you develop severe stomach pain, signs of gallbladder problems, or symptoms of an allergic reaction such as swelling of the face, lips, or throat.

Always read the patient information leaflet provided in your pack for the full list of warnings, precautions, and advice.

What are the ingredients in Wegovy?

Wegovy contains the active medicine semaglutide, which is a GLP-1 receptor agonist. This is the ingredient that helps control appetite, reduce cravings, and support long-term weight loss.

Alongside the active medicine, Wegovy also contains several inactive ingredients. These are added to stabilise the injection solution, keep the medicine safe during storage, and ensure it can be delivered effectively under the skin.

  • Disodium phosphate dihydrate
  • Sodium chloride
  • Water for injections

It is important to note that Wegovy does not contain preservatives, lactose, or gluten.

Patients with known allergies to any of the ingredients should not use this medicine or should discuss it with the prescriber.

If you miss a dose and it’s been less than 5 days, take it as soon as you remember. If it’s been more than 5 days, skip that dose and take the next one on your usual scheduled day. Never take two doses within 72 hours.
Not quite—both contain semaglutide, but Wegovy is specifically approved for weight management, while Ozempic is primarily used for type 2 diabetes. They have different dosing strengths and schedules, so they’re not interchangeable.
Yes, if you use a regulated UK pharmacy like The Care Pharmacy. You’ll complete an online consultation, and approved orders are dispensed and delivered securely. Avoid unregulated sites, as they may sell counterfeit products.
Wegovy starts working from your first dose, but the effects are usually subtle at first. Many people report reduced appetite within the first few injections, with noticeable weight changes becoming clearer after several weeks of consistent use.
No, Wegovy treatment begins at a low dose of 0.25mg once weekly and gradually increases over several weeks. This step-up process helps reduce side effects and gives your body time to adjust. Starting directly at 1.7mg would likely cause unnecessary discomfort.

You can buy Wegovy through regulated UK pharmacies like The Care Pharmacy. After consultation and approval, prescriptions are dispensed and delivered discreetly with free next-day delivery.
Yes, some patients remain on lower doses if higher strengths aren’t tolerated. However, the best results are usually at the 2.4mg maintenance dose. The Care Pharmacy can guide you to find the most effective and comfortable option.

You may feel less hungry and get full quicker. Mild nausea, bloating, or tiredness are common but usually ease as your body adjusts. The side effects generally improve as you continue using the medication.

Wegovy has a half-life of about one week, remaining in the body for several weeks after the last dose. It is taken once weekly.
