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 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 for a long time by controlling appetite and reducing cravings.

Studies have shown that their eating habits become easier to control when combined with sustained physical activity. The reason why Wegovy is effective is that it directly acts on appetite pathways. This makes sure the patient doesn’t have to rely on willpower alone.

Over time, the change in appetite helps form a sustained calorie deficit, which is crucial for clinically meaningful weight reduction. Step by step, people build more consistent routines around food, activity, and sleep, which are the pillars of effective weight management.

What are the eligibility criteria for Wegovy?

Wegovy is intended for adults who meet the following criteria for weight management treatment:

• BMI of 30 kg/m² or above

• Or a BMI of 27 kg/m² or above with at least one weight-related disease, 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, check current medications, and assess any risks to make sure your treatment is safe and effective.

What is the dosing schedule for Wegovy?

Wegovy is administered once each week using a pre-filled pen.  The starting dose is 0.25 mg, and is increased every four weeks according to how your body reacts and adapts to the treatment. The dose is increased slowly and gradually to make sure the side effects are minimised. Generally, the following dosing schedule is followed for Wegovy:

In the first weeks, many people notice they feel full sooner at meals and are less drawn to large portions or late-night snacks. To get sustainable results, patients should create a realistic meal plan, do regular movements throughout the day, make a proper workout schedule, and follow an adequate hydration routine.

How does Wegovy cost vary according to the dosage?

Generally, Wegovy prices vary as the dose increases. The lowest dose is normally the cheapest.

It is important to keep in mind that although the starting doses are cheaper, they are only used for a short period of time while your body adjusts. Once you’re fully adjusted to the medication, most people stay on the 2.4mg weekly injection, and it reflects your long-term Wegovy cost.

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 go through a consultation process to assess your health history and decide if 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 when combined with Wegovy)

• 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.

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

1. Pick a day of the week that is convenient for you.

2. You can inject at any time of day, with or without food.

3. Try to stick to the same day every week so it becomes routine.

Use the pen properly

1. Wash your hands and check the pen label to make sure you have the right strength.

2. Inspect the solution. It should be clear and colourless. Do not use if cloudy or contains particles.

3. Remove the cap and attach a new needle (never reuse needles).

4. Prime the pen if required (see leaflet instructions for your device).

5. Pinch the skin at your chosen site and insert the needle at the correct angle.

6. Press and hold the button until the full dose has been delivered.

Where to inject Wegovy?

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

2. You can use the abdomen, thigh, or upper arm.

3. Rotate the injection site each week to prevent soreness or irritation.

4. 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.

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 make sure it can be delivered effectively under the skin.

The inactive ingredients in Wegovy include:

• 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 discuss it with the prescriber.

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 this, immediately get medical attention.

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 seek immediate medical help 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.
