Buy Wegovy® Online

Wegovy® is a new prescription weight loss treatment that has just been licensed in the UK. They use the active ingredient semaglutide help to control your appetite and keep you feeling fuller for longer, making it easier to stick to that reduced-calorie diet and helping you to lose up to 15% of your starting weight. You'll receive 1 month's treatment in a single FlexTouch pen, and you’ll only need to inject once a week! If you have a BMI of 30 and above and have found that other weight loss treatments haven’t worked for you, Wegovy could be just what you need to hit your weight loss goals.

 

How Wegovy works

Semaglutide is the active ingredient in Wegovy and it is part of a group of medications called GLP-1 receptor agonists. This means it works by helping you to regulate your appetite, reducing hunger and cravings. It stimulates the production of insulin in your pancreas and also helps to reduce the production of a hormone called glucagon. This combination reduces cravings and feelings of hunger and slows down the emptying of your stomach contents, helping you feel fuller for longer. By reducing your appetite, Wegovy injections make it easier for you to stick to a calorie-controlled diet, which naturally makes it easier for you to lose weight.

 

Directions

You’ll use Wegovy once a week. Before injecting this weight loss medication, make sure to wash your hands and check the pen for any damages and the expiration date, then clean the area you’re going to inject with an alcohol swab or soap and water. Your Wegovy FlexTouch pen has enough doses for 1 month (4 doses, 1 dose injected once a week). You must replace the needle and redial the dose after every use.

Remove the pen cap and push a new needle straight onto the pen. Turn until it's tight. The needle is covered by two caps. You must remove both caps. Pull off the outer cap and keep it for later; you will need it to remove the needle safely after injecting. Pull off the inner needle cap and dispose of it. A drop of Wegovy may appear on the needle's tip. If this is your first time using the pen, you must check the flow before use. If not, inject as normal.

To check the flow, hold the pen with the needle pointing up. Press and hold the dose button until the dose counter returns to '0'. A drop of Wegovy should appear on the needle's tip. This means that your pen is ready for use. If it doesn't appear, check the flow again. This should only be done twice. If there is still no drop, change the needle and check the flow again. Do not use the pen if no drop of Wegovy still doesn't appear.

Now it's time to set your dose. Press and hold down the dose button until the desired dose appears on the counter. After selecting your dose, insert the needle into your skin, ensuring the dose counter is still visible. While injecting, press and hold the dose button until it returns to '0'. You may hear a click when it returns to '0'.

Carefully remove the needle from your skin. Bring the needle tip to the outer cap that you kept earlier and push it onto the needle. Unscrew the needle cap and dispose of it in a sharps container. Then put the cap back on your pen to protect the rest of your doses from the light. You may notice a little blood where you’ve injected your pen, this is totally normal, press down on the area lightly with a cotton ball or a gauze pad to stop the bleeding and clean.

 

 

Injection sites

You can choose from a few different injection sites for Wegovy, and your prescriber may recommend one for you. These sites include:

  • Your upper legs
  • Your lower stomach
  • Your upper arms

You can inject into the same area every time you use this treatment, but you should make sure that you don’t choose the exact same injection spot every time. Make sure to avoid any areas of skin that are bruised, broken, tender, red, or damaged in any way.

 

Dosing and titration

When you start taking Wegovy you’ll be prescribed the lowest possible dose (usually 0.25mg a week) and increase strength slowly over time. This process is called titration and it helps your body to adjust to your new medication and reduces side effects. Your health care team will usually review the dose you’re taking every 4 weeks, increasing it once a month until you’re taking the highest possible dose of 2.4mg a week. The key is to keep communicating openly with your prescriber and health care team and follow the dosage instructions they give you carefully.

Warnings

Wegovy pens are not suitable for use in children and teens under the age of 18. Do not use this product if you are allergic to semaglutide or any of the other listed ingredients. Do not take this treatment if you or any of your family have ever had a type of cancer called medullary thyroid carcinoma (MTC) or an endocrine system condition called Multiple Endocrine Neoplasia syndrome type II (MEN 2). Tell your prescriber during your consultation if you have:

  • Kidney problems
  • Pancreas problems
  • Depression, suicidal thoughts, or any other mental health issues
  • Type 2 diabetes

 

Pregnancy and breastfeeding

Wegovy is not suitable for use during pregnancy or breastfeeding, as it’s currently unknown whether the semaglutide in this treatment will affect your child while in the womb or whether it will pass into your breastmilk. Many women find that they gain weight during pregnancy, but if you’re worried about yours you should speak with your doctor or healthcare team and ask for advice. They’ll be able to help you work out why you’re gaining weight, (for example, whether it’s caused by cravings or hormonal changes) and help you to make lifestyle choices that could help you reach and stay at a healthy weight.

 

Other medications

If you’re using any other medication, including herbal remedies and medicines you obtained without a prescription, you should tell your prescriber about them during your consultation for Wegovy. Some medications can interact when used together, causing unwanted side effects or making your medication less effective. You should especially be sure to tell your prescriber if you are already taking:

  • Anticoagulants, also known as blood thinners, such as warfarin
  • Insulin, as your doctor will need to monitor your blood sugar more closely and may change your insulin dose
  • Any other weight loss medications

Frequently Asked Questions

Is Wegovy the same thing as Ozempic?

Wegovy and Ozempic are two medications which use the same active ingredient for different purposes.

They are both manufactured by Novo Nordisk, which holds the patent for both medications at the moment. Ozempic is a medication for patients with type 2 diabetes that helps you to control your blood sugar, and it can be used alone or alongside other medicines like insulin or metformin.

As they both contain semaglutide, these medications work similarly, but that doesn’t mean you can use them interchangeably.

Ozempic is used in different dose sizes to Wegovy, with Wegovy often being prescribed in higher amounts, so if you’re already taking Ozempic for type 2 diabetes you won’t be able to take Wegovy as well, as this could cause an overdose of the active ingredient.

Is a sharps bin included with this product?

Yes, we can supply sharps bins you can use to safely dispose of Wegovy or Saxenda pens.

When you have completed your consultation with our prescribers, the option to include a sharps bin with your order will be there for you to select.

Depending on your order size, we may be able to give you your sharps bin for free, but there may be a charge for smaller orders.

Once you have your sharps bin, you will need to contact your local council to organise collection and its safe disposal when your bin is full.

What is the difference between Wegovy and Saxenda?

Saxenda is another brand of weight loss injection that is very similar to Wegovy.

They work in a similar way, but use different active ingredients and have different dosage sizes. Saxenda uses an active ingredient called liraglutide, which is part of the same group of medicines as semaglutide — GLP-1 receptor agonists.

Saxenda needs to be injected once a day, whereas Wegovy only needs to be injected once a week.

Saxenda pens also need you to set your dose manually and insert a new needle for each dose, Wegovy doesn’t need you to do either of these as each pen is only used once.

The final big difference is that Wegovy has been shown to be much more effective than Saxenda in clinical trials.

With Saxenda you can lose 5% of your starting weight within 12 weeks of taking its maximum dose, but clinical trials of Wegovy have found that patients lose an average of 15% of their starting weight.

Can I drink alcohol while I’m taking Wegovy?

You can drink alcohol while you’re taking Wegovy, it shouldn’t affect the way this treatment works.

However, we always recommend that you drink in moderation and try to drink water or another soft drink between alcoholic drinks to help you stay hydrated.

Something else you should look out for is the calorie content in alcoholic drinks.

Alcoholic drinks often contain a lot more calories than you might expect, so drinking a lot can interfere with your weight loss simply by increasing your calorie intake.

Do Wegovy pens need replacement needles?

Unlike Saxenda, Wegovy pens don’t need you to replace their needles after each use.

This is because Wegovy pens are single-use only, so you won’t need to measure out a dose manually and won’t need to worry about putting a new needle onto your pen.

This is one of the reasons that patients prefer this treatment to Saxenda, as you don’t need to manage dosing or needles by yourself, making the whole process simpler.

How long do Wegovy weight loss injections take to work?

Wegovy injections get to work in your system right away, but that doesn’t mean that the pounds will fall off within a couple of days.

Clinical trials of Wegovy have shown that patients typically lose 15% of their starting body weight during their treatment, but how quickly this happens depends on the number of calories you’re eating every day.

Wegovy works by helping to control your appetite and reduce food cravings, making it easier for you to stick to the low-calorie diet you’ll need to lose weight.

A healthy rate of weight loss is generally considered to be 1 - 2lbs a week, so you may want to use this as a rule of thumb when considering your weight loss goals.

Do I need a prescription for this medication?

You do need a prescription for this medication in the UK.

Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.

When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.

Just like an in-person consultation with your GP, our doctors will assess your answers to their questions and write a prescription for the treatment they think will be best for you.

You’ll then be able to pay for your medication and we’ll send it out to you quickly and in discreet packaging.

Why do you need to know my BMI?

Weight loss treatments are only suitable for use in people with a BMI (body mass index) of 30 or above, or a BMI of 27 or above in those who have weight-related medical conditions. If your BMI is lower than this, then our prescribers won’t be able to recommend this product as a treatment for you.

Starting to take weight loss medication when you have a lower BMI could mean that you lose too much weight and become underweight, which can also contribute to some medical conditions.
