The Wegovy oral tablet is a once-daily pill version of semaglutide, the same active ingredient found in the weekly Wegovy injection. Already using a weight loss injection? You might be wondering whether you can switch to tablets, and how to do it safely.
This guide explains how switching works, what happens if you're moving from Mounjaro, what to expect in the first few weeks, and how the two formats compare day to day. For a broader overview of the tablets, including how they work and their dosing schedule, see our complete guide to the Wegovy tablets.
Switching between any weight loss treatments should always be done with your prescriber, never on your own. So treat this guide as background information, not a replacement for advice about your own circumstances.
Do not stop your injection or start the tablets without speaking to your prescriber first.
How to switch between Wegovy injection and tablets
The injection and the tablets contain the same active ingredient, so moving between them is more straightforward than switching to a different medicine.
You take your final injection as normal. Then you start the tablets on the day your next injection would have been due. For example, if you injected on a Monday, you'd start the tablets the following Monday.
Switching from Wegovy tablets to the injection instead? You start the injection the day after your final tablet.
The equivalent Wegovy tablet doses for each Wegovy injection dose are in the table below:
| Current Wegovy injection dose |
Wegovy tablet starting dose |
| 0.25mg |
1.5mg |
| 0.5mg |
4mg |
| 1mg |
9mg |
| 1.7mg |
9mg |
| 2.4mg |
25mg |
If you're on the 2.4mg dose of the weekly injection, you can move straight to the 25mg daily tablet. For any other dose, including the 7.2mg injection, your prescriber will decide on a sensible starting dose for the tablet. They'll base this on your current injection dose and how well you've tolerated treatment.
That's because your body absorbs semaglutide a little differently from a tablet than from an injection. So your prescriber may choose a different dose from the one in the table.
Whatever your current dose, do not stop your injection or start the tablets without speaking to your prescriber first.
How to switch from Mounjaro to Wegovy tablets
Mounjaro contains tirzepatide, which is a different active ingredient from semaglutide. Tirzepatide acts on two hormone receptors (GLP-1 and GIP), while semaglutide acts on one.
Because they're different molecules, there's no established way to convert a Mounjaro dose into an equivalent Wegovy tablet dose. And the two must not be taken together.1
Do not take Mounjaro and Wegovy tablets together. Finish one before you start the other.
So Pharmica doesn't carry your Mounjaro dose across into a matching tablet dose. If you switch from Mounjaro to Wegovy tablets, you take your last Mounjaro injection and wait two weeks. Then you start at the beginning tablet dose of 1.5mg and titrate up through 4mg, 9mg and 25mg, with at least a month at each step.
Starting low and building up gives your body time to adjust to a new medicine. It also lowers the chance of digestive side effects, and avoids assuming a dose match that hasn't been clinically established between two different medicines.
Your appetite may feel different during the changeover. That's a normal part of moving between treatments, not a sign the new one isn't working.
You may also regain some weight until you reach your maximum tolerated dose or maintenance dose again. That's to be expected, as you're starting again from a lower dose.
It isn't necessarily a sign the treatment isn't working, either. That can only be judged once you've finished titrating (gradually increasing your dose) and have been on your maximum tolerated dose for at least three months.
As always, do not stop Mounjaro or start the Wegovy tablets without your prescriber's guidance.
What to expect in the first few weeks after switching
Your body absorbs the tablets differently from the injection, so you might notice some changes in how you feel.
The injection gives you a steady level of medicine across the whole week. The tablet is taken daily, and how much you absorb can vary a little from day to day, depending on how closely you follow the fasting and timing rules.
In the first one to three months after switching, some people find their appetite control feels a bit less consistent than it did on the injection. You might feel hungrier later in the day, or notice your hunger changes from one day to the next. This usually settles as your dose goes up and your body adjusts.
A consistent daily routine is key. The tablet only works fully when it's taken on an empty stomach (at least 8 hours since you last ate anything), followed by the 30-minute wait. So building that morning habit matters more with the tablet than with the injection.
Keep your tablets by your bed. Taking one as soon as you wake up makes the empty-stomach rule much easier.
Wegovy tablets vs the injection: side by side
Both formats deliver semaglutide and work in the same way. The practical differences are what most people weigh up, and our guide to Wegovy tablets vs the injection explores these in more depth.

Who might the tablet suit best?
There's a lot to weigh up before switching from the injection to the tablet. It suits some people really well, but might be a poor fit for others.
It may be a good option if you:
- Would rather avoid needles, or find self-injecting gets in the way of staying consistent
- Want a treatment that doesn't need a fridge, which can be simpler if you travel
- Have a reliable morning routine and can take a tablet the same way every day
- Simply prefer taking a pill
It may be less suitable if you:
- Find it hard to stick to a strict fasting and timing routine, for example because of shift work or an unpredictable schedule
- Take other medicines first thing in the morning that can't easily be delayed by 30 minutes or more
- Get nausea or reflux when you take medicine without food
- Are losing weight steadily and getting on well with your current injection, in which case there may be little reason to change other than personal preference
Some people shouldn't use semaglutide in either form, or need extra caution. It isn't recommended if you have severe kidney or liver problems, and it shouldn't be used during pregnancy or while breastfeeding.
Your prescriber will review your full medical history before agreeing to any switch, to make sure it's suitable for you. Be sure to tell them about any health conditions you have and any medicines you take.1
When to seek advice
Contact your GP or prescribing clinician if you:
- Experience severe or persistent nausea, vomiting or abdominal pain
- Develop severe upper abdominal pain that spreads to your back, which can be a sign of pancreatitis
- Notice signs of low blood sugar (shakiness, sweating, confusion), especially if you also take insulin or a sulfonylurea for type 2 diabetes
- Are unsure about your dose, your timing, or how to manage the gap between your last injection and your first tablet
A full list of side effects and interactions is in the patient information leaflet that comes with your medicine. If you have type 2 diabetes, tell your prescriber, as your other diabetes medicines may need adjusting.1
Frequently asked questions
Are the side effects worse on the tablets than the injection?
Not necessarily. Because both contain semaglutide, the side effect profile is broadly similar. The most common effects are gastrointestinal: nausea, diarrhoea, vomiting, constipation and abdominal pain are all classed as very common (affecting more than 1 in 10 people), and they tend to be most noticeable when you first start or increase your dose. The main difference is that the injection can occasionally cause mild irritation at the injection site, which does not happen with a tablet.1 2
Will I start on the 25mg tablet straight away?
Only if you are switching from the 2.4mg weekly injection. From any other injection dose, or from Mounjaro, your prescriber will choose an appropriate starting dose and titrate you up. Do not assume you can begin at the maintenance dose right away.2
Can I take the tablet and the injection at the same time?
No. You should not double up on semaglutide, and semaglutide must not be combined with another GLP-1 medicine such as Mounjaro. The approach is to take your last injection, wait two weeks, then begin the tablets.2
Can I switch back to the Wegovy injection if the tablet does not suit me?
Yes. Because the tablet and the injection contain the same active ingredient, it is possible to move back to the injection if the tablet does not work for you, for example if the daily fasting and timing routine is hard to keep to. As with any switch, this should be planned with your prescriber, who will confirm the right injection dose and timing rather than you changing over on your own.
Will my appetite change when I first switch to the tablet?
It can. Moving from a weekly injection to a daily tablet can change how you feel because the injection gives a steady level of medication across the week, whereas the tablet's absorption varies a little day to day. In the first one to three months some people find their appetite control feels slightly less consistent, or notice more hunger later in the day. This usually settles as your dose increases and your body adjusts, and it is not a sign the tablet is not working.
Can I have tea or coffee when I take the tablet in the morning?
No. The tablet must be taken on an empty stomach (a minimum of 8 hours since you last ate anything) with a small sip of plain water only (no more than 120ml), and you then need to wait at least 30 minutes before eating or drinking anything else, including tea or coffee. Eating or drinking sooner than 30 minutes reduces how much semaglutide your body absorbs.2
