The importance of using Wegovy correctly

Wegovy (semaglutide) is a GLP-1 receptor agonist, which means it mimics a natural hormone that helps regulate appetite and blood sugar¹.

For many people, it forms part of a structured weight loss plan that includes changes in food habits, movement, sleep, and weekly coaching ² .

Correct use matters because it ensures you get the full benefit from each dose and reduces the chance of side effects .

We understand that starting an injectable treatment can feel like a big step. Many people tell us they worry about “doing it wrong”, or feel anxious about needles or side effects.

These feelings are normal. At Medicspot, a clinician reviews each case, we always verify your medical history using your NHS Summary Care Record (SCR), and your health coach is there to guide you week by week.

Every person I speak to has the same fear at the start: ‘What if I mess this up?’ The truth is that the pen is designed to be simple. Once you’ve done it once or twice, it becomes part of your weekly routine.

Your weekly routine

You will inject Wegovy once a week, on the same day each week. It does not matter what time of day you take it, or whether you have eaten³. Most people choose a day that already has a reliable habit built in (for example, Sunday evenings or Monday mornings).

Your dose will increase gradually, often every 4 weeks, until you reach the maintenance dose of 2.4mg, or the highest dose you tolerate. This slow increase is designed to give your body time to adjust and reduce symptoms such as nausea.

What you might feel in the first few weeks

People often ask what they will notice. Early on, you may feel:

  • a calmer appetite
  • feeling full sooner than usual
  • reduced snacking
  • occasional nausea or mild stomach discomfort

These changes are part of how GLP-1 medications work. If symptoms become difficult, your Medicspot team can help you adjust. You are never expected to manage alone.

Step 1 - Gather what you need

  • Your prescribed Wegovy pen (check the dose on the label).
  • A clean space to sit or stand.
  • An alcohol wipe or soap and water.
  • A cotton ball or gauze pad.
  • A sharps disposal container.

Check the pen before use. The liquid should be clear and colourless, the expiry date should be valid, and the device should not look damaged⁴.

Step 2 - Choose your injection site

You can inject in one of three areas:

  • the front of your thigh
  • your lower abdomen (avoiding a 2 inch area around the belly button)
  • the upper arm (outer area; some people ask for help)

Rotating injection sites is important because injecting in the same exact spot each week may cause irritation or small lumps.

Choose an area of skin that is calm, not bruised, hard, or sore.

Clean the area and let it dry fully.

Step 3 - Inject your first dose

    • Pull off the pen cap
    • Select a new needle, and remove the paper tab
    • Push the needle onto the end of the pen, and turn until tight.
    • Remove the outer cap from the needle – keep this safe to remove the needle afterwards.
    • Remove the inner cap and dispose of this.
  • For your first dose only – check the flow of the pen. Turn the dial a couple of clicks until it shows two little dots and a dash and that these line up with the dose indicator.
  • Press the dose button on the end of the pen until the indicator returns to zero, and a drop of wegovy can be seen on the needle. If no drop appears, repeat checking the flow again (only do this twice in total).
  • Next, turn the dial until the dose indicator shows your dose and the dial stops turning.
  • Insert the needle into your chosen injection site
  • Press the dose button down and hold until the dose indicator shows 0 again. Continue to hold and slowly count to 6 before removing the pen
  • Lift the pen away.

If you see a tiny drop of blood, press gently with your cotton ball – do not rub.

People often describe this part as “less painful than expected”, “a quick sting”, or “barely noticeable”.

Step 4 - Safely dispose of the needle

Use the outer cap saved earlier and place over the needle, and then unscrew the needle from your pen. Dispose of this needle in your sharps bin each time. Ensure you use a new needle each time you administer a dose.

Step 5 - Store your pen

  • Keep in the fridge in the original carton (2-8 °C).
  • A pen can stay at room temperature (up to 30°C) for 28 days once removed from the fridge – but only if protected from heat and light⁴.
  • Do not use pens that have been frozen, damaged, or left out for too long.

Missed doses - what to do and what not to do

Even with the best intentions, people miss doses. If this happens:

  • If it has been 48 hours or less, take the missed dose as soon as you remember and then return to your usual routine.
  • If it has been more than 48 hours, skip the missed dose and wait until your next scheduled dose.

Do not double the next dose. Doubling increases the risk of nausea without improving results.

If you want to change your weekly injection day, leave at least 5 full days between doses.

Common mistakes and how to avoid them

Most mistakes are easy to prevent once you know what to look out for. Here are the issues we see most often:

Stopping the injection too early

  • This happens when the pen is lifted either when the dose indicator is not yet showing zero, or not held for a short period after getting to zero
  • Ensure the indicator shows zero and you have waited at least a slow count of 6 after this point before removing the pen.

Using the same spot every week

  • This happens out of habit or convenience
  • Rotate between your abdomen, thigh and upper arm

Feeling rushed

  • This happens when injecting during stressful or busy moments
  • Choose a calm, predictable time each week and link it to an existing habit

Delaying injections due to fear or uncertainty

  • This happens because of anxiety about needles or nausea
  • Speak with your health coach – most people find it easier after the first dose
