Wegovy (semaglutide) is a GLP-1 receptor agonist – a medication that mimics the natural hormone GLP-1, which regulates appetite, slows digestion, and helps control blood sugar.¹
The 0.5mg dose is the second step in the Wegovy treatment plan, usually taken after four weeks at 0.25mg. It’s designed to gently increase your body’s exposure to semaglutide while minimising Wegovy side effects.
At this stage, your body is learning a new rhythm: feeling full sooner, experiencing fewer cravings, and gradually shifting towards a healthier relationship with food.
“Many people tell me the 0.5mg dose is the first time they feel real appetite control. That’s when the work begins – building habits around that new feeling so it lasts long after treatment.”

A Wegovy 0.5mg pen costs £109 for the first month, and then £159 for subsequent months. This includes ongoing medical oversight and access to Medicspot’s coaching support, helping you stay consistent, manage side effects, and get the most from your treatment.
If you’re already using Wegovy, you can easily switch to Medicspot. We’ll just need proof of your current prescription, such as:
Most people start Wegovy at 0.25mg for four weeks, then move up to 0.5mg for another four weeks.
However, there’s no one-size-fits-all plan. Your clinician may recommend staying on 0.25mg longer if you:
Wegovy works well when increased gradually. Rushing up the doses too fast doesn’t mean faster weight loss – it can actually make you feel worse and risk stopping treatment early.
This calculator uses data from a major clinical study on GLP-1 weight loss treatment to show what typical progress looks like. Your results will depend on your specific medication, dose, lifestyle, and medical history.
Based on the results of a clinical study with 806 participants.
Most people notice a drop in appetite during this stage. You might feel full sooner, or lose interest in foods you used to crave.
This is your chance to practise mindful eating – listening to your hunger cues and eating slowly. You may find smaller portions satisfying for the first time in years.
“Try putting your fork down halfway through a meal. Check in with your body – are you satisfied? This simple habit helps you reconnect with your natural fullness signals.”
– Laura
Wegovy 0.5mg can help stabilise blood sugar levels, which may reduce cravings for some people. But side effects are still common, such as nausea, bloating, and constipation.
These symptoms don’t mean the medication isn’t working. They’re a normal sign your digestion is slowing down as GLP-1 hormones do their job.
Here are 5 gentle ways to ease side effects:
It’s completely normal to have mixed feelings right now – excitement about progress, but also frustration if side effects appear or the scale isn’t moving as fast as you hoped.
Medicspot’s coaching team encourages members to track both physical and emotional progress, because motivation often comes from how you feel day to day, not just what the scales say.
“Remember, the 0.5mg stage is still early. Focus on consistency, not perfection. Every week you stay consistent, even if progress feels slow, you’re retraining both your body and your brain.”
– Laura
Before listing side effects, it’s important to know that you’re not failing if you feel rough. Many members feel some discomfort in the first few months – it’s part of your body learning to respond to a new hormone signal. Most side effects ease with time.
If you experience severe abdominal pain, this could be a sign of pancreatitis (a rare side effect of GLP-1 medications) and requires urgent medical review.²
| Common side effects at the 0.5mg stage | |
|---|---|
| Nausea or upset stomach Wegovy slows how fast your stomach empties. |
Eat slowly, avoid high-fat foods, and try ginger or mint tea. |
| Constipation Slower digestion. |
Drink 2L of water daily, add fibre (fruit, veg, oats), and walk regularly. |
| Bloating or burping Food stays in your stomach longer. |
Eat smaller meals, chew thoroughly, and avoid lying down after eating. |
| Tiredness Lower calorie intake. |
Eat balanced meals with protein and complex carbs; rest as needed. |
| Headache Mild dehydration or sugar change. |
Stay hydrated and don’t skip meals. |
| Mild bruising around the injection site | Vary the injection site. |
Typically, you’ll stay on the 0.5mg dose for about four weeks before increasing to 1.0mg. But it’s not a race. You might stay on 0.5mg longer if you:
What to look out for
Mild side effects are normal and to be expected. If you feel your symptoms are more severe than you expected or you are concerned please contact us.
We would always want to know about stomach pains that feel a little more than a mild discomfort or if you start feeling unwell. Any unusual redness or discharge from your injection site is also something to look out for.
“Members often worry they’ll ‘fall behind’ if they don’t increase on schedule. In reality, staying at a lower dose a little longer can make the whole journey easier and more sustainable.”
– Laura
