Switching from Wegovy injections to Wegovy tablets

In early 2026, the US Food and Drug Administration (FDA) approved Wegovy pills for helping manage obesity, providing a needle-free option for weight loss. However, in Ireland, they're still currently under review by the Health Product Regulatory Agency (HPRA).

If you're already taking Wegovy and are interested in switching from injections to Wegovy tablets once they become available, then we’ve laid out the differences are between the two treatments, how to switch safely and reasons you might want to make the change.

Key points

• Same medicine, different format: Wegovy tablets and injections both contain semaglutide and work in the same way. However, since they’re absorbed differently, the doses aren’t like-for-like.
• Effectiveness differs, but both work: Injections currently show higher average weight loss in clinical trials, but tablets still deliver results that can improve your health.
• Lifestyle fit matters: Choosing between injections and tablets often comes down to preference, routine, and what you’re most likely to stick with long-term.

How to switch from Wegovy injections to Wegovy tablets

If the tablets are approved in Ireland, and you're interested in switching from Wegovy injections to pills, you should always speak to your clinician first. They will help you safely move from one treatment to another, while also letting you know what to expect.

Below is an example dose conversion for switching from Wegovy injections to Wegovy pills:

If you’re on Wegovy 7.2mg, you can also switch to a 25mg pill. The 25mg tablet is less effective than 7.2mg, but slightly more effective on average than 2.4mg, and has the added convenience of being a daily tablet over a weekly injection. That may make it easier to stick to as your maintenance dose.

Do Wegovy tablets work in the same way as injections?

Yes, Wegovy tablets and Wegovy injections work in the same way inside the body. Both contain the same active ingredient, semaglutide, and belong to a group of medicines known as GLP-1 receptor agonists.

This means they mimic a natural hormone that helps regulate your appetite, slow digestion, and control blood sugar levels. In both tablet and injection form, semaglutide works by helping you feel fuller for longer, reducing hunger, and making it easier to eat less.

The main difference isn’t how the medicine works, but how it gets into your body. Injections deliver semaglutide directly into the bloodstream, while tablets combined with a 'carrier molecule' that protects the medicine and helps it be absorbed through the digestive system. This is why their dosages are different.

Are Wegovy tablets as effective as weight loss injections?

In clinical trials, the newest 7.2mg Wegovy injections helped participants achieve around 21% average weight loss over 72 weeks. Wegovy tablets, meanwhile, produced average weight loss of around 17% across a similar time frame. However, participants who were early responders (having lost 10% starting body weight by week 16) saw an average of up to 22% weight loss.

However, these figures are just for guidance. Your personal weight loss will depend on how you react to the treatment, how well you stick to the guidelines, and other lifestyle changes like your diet and level of physical activity.

And the Health Service Executive (HSE) advises that even losing 5-10% of your body weight can bring positive health improvements, like lowering your:

• blood glucose
• blood pressure
• cholesterol

Additionally, the SELECT trial observed a 20% reduction in major adverse cardiovascular events (MACE) like heart attacks and strokes, in overweight or obese adults taking Wegovy injections. At present, no studies have conducted exploring Wegovy tablets and heart health.

Is it safe to switch from weight loss injections to Wegovy tablets?

Based on current evidence, switching from Wegovy injections to Wegovy tablets is considered to be safe under the guidance of a healthcare professional. Both forms contain the same active ingredient, semaglutide, so will interact with your body in similar ways, despite being absorbed differently.

Importantly, if you're considering making any change to your treatment plan then you should always discuss this with your healthcare professional first.

In this case, while working similarly, tablets and injections are absorbed differently and follow different dosing schedules. A prescriber will be able to give you tailored advice about how to transition, and what to expect when switching.

Before this, they'll need to check certain things to make sure the switch is right for you, like:

• your current dose
• how well you're tolerating treatment
• your overall health

Key points to consider before switching from injections to tablets

There are several reasons why someone might choose to switch from Wegovy injections to tablets. The right option will depend on your lifestyle, preferences, and what works best for you.

Convenience

For some people, taking one injection a week is their preferred option for weight loss. Others may find the ease of taking a tablet every morning more appealing.

Whether it’s prescription medications or vitamins, most people have a morning routine that tablets can easily fit into.

Tablets can also be easier to store, as they don’t need to be kept in your fridge before use.

Maintenance

After reaching your weight loss goals, you may prefer a pill as part of your longer-term maintenance plan. Tablets may help you keep weight off while stopping injections.

Preference

Some people simply prefer taking a tablet over using injections. If you’re uncomfortable with needles or would rather avoid injecting yourself, switching to a tablet option may feel more manageable.

Injections may not suit everyone. For example, you might struggle with:

• confidence in self-injecting
• injection site discomfort
• managing a pen device or weekly dosing

In these cases, a tablet could offer a more practical alternative.

Frequently asked questions about switching from weight loss injections to tablets

Can I switch from Mounjaro to Wegovy pills?

If you’re using Mounjaro and are considering switching to Wegovy pills, this should only be done with clinical support. Below is an example dose conversion between the two treatments:

Always speak to your clinician before making any changes to your medication, including stopping or switching.

Are side effects worse on Wegovy tablets?

In studies, tablets have produced similar side effects to Wegovy injections.

Common side effects include:

• nausea
• vomiting
• diarrhoea
• constipation

As with injections, these side effects are usually mild and often improve as your body adjusts.

The main difference is that injections can sometimes cause mild irritation at the injection site, which won’t happen with tablets.

How often do you take Wegovy tablets?

Wegovy tablets are taken once a day. It’s recommended to take them when you first wake up, as you’ll need to wait 30 minutes before having any food or other oral medications to allow them to be properly absorbed into your system.

Will I experience withdrawal symptoms when I stop taking my injections?

Wegovy doesn't usually cause traditional withdrawal symptoms, whether you switch to tablets or stop taking the injections. However, after stopping treatment, appetite may increase again.

Your prescribing pharmacist will help you navigate switching, as well as letting you know everything you might encounter when changing.

Summary of switching from weight loss injections to Wegovy tablets

“If you’re currently using Wegovy injections, it’s worth thinking ahead about whether a tablet option would suit you if it becomes available in Ireland.

“Ask yourself: do you prefer a simple daily routine, or does a once-weekly dose fit your lifestyle better? Would avoiding injections make it easier to stay consistent, or are you comfortable with how you take your treatment now? Can you realistically stick to the timing requirements that tablets may involve?

“If any of that resonates, a tablet could be a better fit from a lifestyle point of view. That said, in Ireland the approved and available option for weight management right now remains injectable treatments like Wegovy, which offer consistent dosing and are supported by established evidence.

“Any future switch would come down to how well your current treatment is working for you, how well you tolerate it, and whether a different format genuinely makes it easier to stay on track long term, rather than preference alone.”
