The Wegovy pill is coming to the UK. One of the first questions people ask is simple: what is actually different?
The two options share an active ingredient but they are not interchangeable. How you take them, how well they work and who they suit are all different. Here is what you need to know.
Same active ingredient. Different delivery.
Both the Wegovy tablet and injection contain semaglutide. It is a GLP-1 receptor agonist that helps regulate appetite, slows stomach emptying and helps you feel fuller for longer. In simple terms, the mechanism is the same. The delivery is not.
The injection is taken once a week and delivers semaglutide under the skin. The pill is taken daily and has to be absorbed through the stomach wall.
Because of this, results do differ slightly.
Results: what the trials show
The Wegovy injection at 2.4mg weekly leads to around 15% average weight loss over 68 weeks in clinical trials. Some people lose more. A higher 7.2mg dose has shown around 21% over 72 weeks.
The Wegovy pill at 25mg daily shows around 15% weight loss over 64 weeks in the OASIS 4 trial. That is broadly comparable to the standard injection dose.
Although this gives an estimate to what you can expect, results are not fixed. They depend on your dose, how long you stay on treatment and how consistently you follow the protocol. For the pill, consistency is critical.
How you take them
This is the biggest practical difference.
Wegovy injection
- Once weekly
- Injected into the abdomen, thigh or upper arm
- No food or timing restrictions
- Stored in the fridge
Wegovy pill
- Once daily
- Taken first thing in the morning on an empty stomach, with 120ml of plain water
- Wait 30 minutes before food, drink or other medication
- Stored at room temperature
- No sharps disposal required
The routine for the pill is not optional – it’s a carefully designed process which is what makes it work.
Semaglutide is a peptide. It breaks down in the stomach before it can be absorbed. The pill includes SNAC to temporarily change stomach conditions and allow absorption. That only works when the stomach is empty and nothing else interferes.
In real world data, around 31% of people do not follow this consistently after the first month. When that happens, the drug may seem less effective when the issue is timing.
If your mornings are predictable, this can work well. If they are not, it is worth discussing whether the pill is practical for you.
Drug interactions
The pill changes how you time other medications. You need to avoid taking other oral medications during the 30 minute window after your dose.
At CheqUp, your full medication schedule is reviewed before you start and at each renewal and our Clinicians will advise you on when you can take these alongside the Wegovy pill. This is not something you need to manage alone.
Who each option suits
The injection may suit you if you:
- Want to achieve the most weight loss on semaglutide
- Prefer a once weekly routine
- Have used semaglutide before
- Have a history of cardiovascular disease
The pill may suit you if you:
- Prefer not to inject
- Have a consistent morning routine
- Are starting treatment for the first time
- Want to move to an oral GLP-1 without changing the active ingredient
- Are a frequent traveller
- Are a shift worker
What stays the same
Whichever option you choose, you are on the same CheqUp programme.
Same clinical team. Same health coaching. Same support and advice.
Only the format of the medication changes.
However, this decision should not be made alone. To choose the right medication for you, you will need to fill in a short medical questionnaire and answer questions on your medical history.
The Wegovy pill is coming. We are ready for it. If you want to talk through your options, our clinical team is here.

CheqUp plans to offer both the Wegovy pill and Wegovy injection as part of our full weight management programme. Oral GLP-1 treatments are not yet licensed in the UK. This page will be updated once MHRA approval is confirmed.
Frequently Asked Questions (FAQ’s)
Can I switch from the Wegovy injection to the pill?
Yes, switching is possible but it is a clinical decision, not something to do without guidance. The dose you move to depends on which injection dose you are currently on, and the timing of the switch needs to be managed carefully. If you are a CheqUp member and want to explore switching, speak to your Clinician through My Account (link)
Is the Wegovy pill as effective as the injection?
At the standard doses, the results are broadly comparable, around 15% average weight loss for both. A higher injection dose of 7.2mg has shown up to 21% in trials, which the pill does not currently match. For the pill, how consistently you follow the morning fasting protocol has a significant impact on how well it works in practice.
Can I take the Wegovy pill if I take other medications in the morning?
It depends on which medications you take. You need to wait 30 minutes after taking the pill before taking anything else orally. For some medications, particularly levothyroxine and certain heart or epilepsy drugs, timing needs careful planning. Your CheqUp Clinician will review your full medication list before prescribing.
What happens if I miss the 30-minute fasting window?
If you eat or drink something other than plain water within 30 minutes of taking the pill, absorption may be reduced. It is not a wasted dose, but it may be less effective. If this happens regularly, it is worth raising with your Clinician as repeated missed windows can affect your overall results and it may be worth reviewing whether the pill is the right format for your routine.
What is SNAC?
SNAC stands for Salcaprozate sodium. It is a compound included in the Wegovy pill that makes oral semaglutide possible.
Semaglutide is a peptide, which means it would normally be broken down by stomach acid before it could be absorbed. SNAC solves this by briefly changing the conditions in the stomach lining immediately around the tablet, creating a short window where semaglutide can pass through the stomach wall and into the bloodstream before it is degraded.
This is why the fasting protocol matters. SNAC only works effectively on an empty stomach with a limited amount of plain water. Food, other drinks and other oral medications all interfere with this process – the window closes and significantly less semaglutide is absorbed.
Are the side effects different between the Wegovy injection and the pill?
The side effects are generally similar for both forms and may include mild gastrointestinal symptoms such as nausea, vomiting, constipation, indigestion (dyspepsia), and diarrhoea. However, clinical studies showed that a higher number of patients experienced dyspepsia (indigestion) when taking the Wegovy pill.
