Wegovy FlexTouch Pen: How to Use and Dose Guide

Starting a medical weight management journey is a big step, and if your doctor has prescribed Wegovy, you might be feeling a mix of excitement and nervousness. You are not alone. Millions of people are exploring semaglutide (the active ingredient in Wegovy) to help manage their weight and improve their long-term health.

However, holding a medical device in your hand can be intimidating. Depending on your region, your prescription may come in the Wegovy FlexTouch pen. Unlike single-use auto-injectors, the FlexTouch pen is designed to deliver multiple doses over a month. It gives you control, but it also requires a specific technique to ensure you get the full benefit of the medication.

This guide is designed to be your friendly companion. We will walk you through exactly how to use the Wegovy FlexTouch, understand the dosing schedule, and manage your treatment safely and effectively.
 

The Wegovy FlexTouch pen is a pre-filled, multi-dose prescription pen used for weight management. It contains semaglutide, a medication that mimics a natural hormone in your body called GLP-1. This hormone targets areas of the brain that regulate appetite and food intake, helping you feel fuller for longer and reducing cravings.

While the standard Wegovy device in the United States is often a single-use pen, the Wegovy FlexTouch (commonly used in the UK, Europe, and increasingly other markets) works differently.

Key features of the FlexTouch include:

• Multi-use: One pen usually contains four doses (enough for one month of treatment).
• Dial-a-dose: You manually turn a selector to set your dose.
  Needle attachment: You must attach a new, sterile needle for every single injection.

Understanding these mechanics is the first step toward a successful experience.
 

One of the most important aspects of taking Wegovy is the "titration" schedule. You do not start at the maximum dose. instead, you slowly increase the amount of medication over several months. This allows your body to adjust to the medicine and minimises side effects like nausea.

Your doctor will guide your specific plan, but the standard schedule generally looks like this:

• Month 1 (Weeks 1–4): 0.25 mg once weekly.
• Month 2 (Weeks 5–8): 0.5 mg once weekly.
• Month 3 (Weeks 9–12): 1.0 mg once weekly.
• Month 4 (Weeks 13–16): 1.7 mg once weekly.
• Maintenance (Week 17 onwards): 2.4 mg once weekly.

The Wegovy FlexTouch pens are colour-coded to match these specific doses. For example, you will use a specific pen for the 0.25 mg month, and a different pen for the 0.5 mg month. Never try to calculate or guess doses; always use the pen prescribed for your current stage of the schedule.
 

Using the pen correctly ensures the medication works as intended. Follow these steps carefully.

Phase 1: Preparation

1. Check your pen: Look at the label to ensure it is the correct dose (e.g., 0.25 mg or 1.0 mg). Check the expiration date.
2. Inspect the liquid: Look through the pen window. The liquid should be clear and colourless. If it looks cloudy or colored, do not use it.
3. Wash your hands: Cleanliness is crucial to prevent infection. Wash your hands thoroughly with soap and water.
4. Gather supplies: You will need your pen, a new disposable needle (usually NovoFine or NovoTwist), and an alcohol swab.

Phase 2: Attaching the Needle

The Wegovy FlexTouch does not come with a needle attached. You must put a new one on every time.

1. Peel the tab: Take a new needle and peel off the paper tab on the back.
2. Push and twist: Push the needle straight onto the pen and twist it until it is tight.

3. Remove caps:

Pull off the outer needle cap and save it (you will need it to remove the needle later).
Pull off the inner needle cap and throw it away. You should now see the needle tip.

Phase 3: Checking the Flow (Priming)

Important: If you are using a new pen for the first time, you must check the flow. This removes air bubbles and ensures the needle is not blocked.

1. Turn the dose selector to the "flow check" symbol (usually two dots or a line).
2. Hold the pen with the needle pointing up. Tap the cartridge gently so any air bubbles rise to the top.
3. Press and hold the dose button until the counter returns to 0.
4. You should see a drop of liquid appear at the needle tip. If you see the drop, the pen is ready. If not, repeat the step.

Note: You only need to do this step before the FIRST injection of a new pen.

Phase 4: Selecting and Injecting Your Dose

1. Dial the dose: Turn the dose selector until the dose counter shows your prescribed dose. Stop when the number aligns with the dose pointer.
2. Clean the site: Use an alcohol swab to clean the area of skin where you plan to inject. Let it dry.
3. Insert the needle: Insert the needle into your skin (subcutaneously). Your doctor or nurse will show you the correct technique.
4. Inject: Press and hold down the dose button. You will hear or feel a click as the dial returns to 0.
5. Hold and count: After the counter hits 0, keep the needle in your skin and count slowly to 6. This ensures that the full dose has been delivered.
6. Remove: Pull the needle straight out.

Phase 5: Disposal

1. Carefully put the outer needle cap back on the needle.
2. Unscrew the needle and dispose of it immediately in a sharps container. Never store the pen with a needle attached.
3. Put the pen cap back on to protect the medication from light.
 

Wegovy is a subcutaneous injection, meaning it goes into the fatty layer just under your skin. You have three main options for injection sites:

• The Stomach (Abdomen): You can inject anywhere on your stomach, provided you stay at least 2 inches away from your belly button.
  The Thighs: The front of your thighs is a popular and easy-to-reach location.
  The Upper Arm: You can use the fleshy outer part of your upper arm. This can be tricky to do yourself, so you might need a family member to help if you choose this spot.
• Pro Tip: Rotate your injection sites each week. For example, if you inject in your right thigh this week, try your left thigh or your stomach next week. This helps prevent soreness and keeps the skin tissue healthy.
   

Proper storage is essential to keep the medication effective.

• Unopened Pens: Store them in the refrigerator between 36°F and 46°F (2°C to 8°C). Do not freeze them; if the pen freezes, the medication is ruined and must be thrown away. Keep them in the original carton to protect them from light.
• Currently In-Use Pens: Once you have used a pen for the first time, you can usually keep it for up to 6 weeks. You can store the in-use pen in the refrigerator or at room temperature (below 86°F / 30°C).
• Travel: If you are travelling, keep the pen in your carry-on bag, not checked luggage (where it can freeze).

Always remove the needle after every injection. Storing the pen with a needle attached can allow air to get into the cartridge or medication to leak out, which affects the accuracy of your next dose.
 

Like all medications, Wegovy can cause side effects. Because the Wegovy FlexTouch delivers a powerful hormone, your digestive system needs time to adapt.

The most common side effects include:

• Nausea
• Diarrhoea
• Vomiting
• Constipation
• Stomach pain

Tips to manage these symptoms:

1. Eat slowly: Consuming food too quickly can trigger nausea.
2. Smaller meals: Try eating smaller portions throughout the day rather than three large meals.
3. Stay hydrated: Drink plenty of water, especially if you experience diarrhoea or vomiting.
4. Avoid high-fat foods: Greasy or fried foods can make nausea worse while on Wegovy.

If side effects become severe or if you experience severe stomach pain that will not go away (which could be a sign of pancreatitis), stop using the medication and contact your healthcare provider immediately.
 

The Wegovy FlexTouch pen is a powerful tool in the fight against obesity and weight-related health issues. While the mechanism of dialling and injecting might seem technical at first, it quickly becomes a simple part of your weekly routine.

Remember, the medication is most effective when combined with the lifestyle changes recommended by your doctor, such as a balanced diet and increased physical activity. By following the proper storage guidelines, rotating your injection sites, and adhering to the dosing schedule, you are setting yourself up for the best possible results.

Always consult your healthcare provider if you have questions about your specific medical condition or if you are unsure about how to use your device.
