Wegovy Pill

What is the Wegovy pill?

The Wegovy pill is a once-a-day weight loss tablet containing semaglutide, the same active ingredient found in the Wegovy injection. The pill can help reduce your appetite, quieten food noise, and make you feel fuller for longer. This means it can support long-term weight loss when used alongside other positive lifestyle changes, like a healthier diet and increased physical activity.

If you don’t like needles, or would prefer a daily rather than weekly medication, the Wegovy pill might be a better fit than injectable treatments like Wegovy and Mounjaro.

How do Wegovy pills work?

Wegovy pills are a GLP-1 receptor agonist and work by mimicking the GLP-1 hormone your body naturally produces. It activates receptors in the brain to reduce your appetite while slowing how quickly food leaves your stomach.

This can mean people taking it may:

• feel fuller faster during meals
• have fewer cravings and less of an urge to snack
• find it easier to eat less without feeling deprived

However, they're not a quick fix. Wegovy pills work best when you're also eating well and moving more.

What makes the pill possible is a clever bit of science. Your stomach can't tell the difference between medicine and food, so it would normally just break the semaglutide down before it can do anything.

To get around this, the semaglutide is combined with a special carrier molecule that acts like a bodyguard, protecting it just long enough to be absorbed into your bloodstream. Once it's there, it works exactly the same way as the injection.

How long does the Wegovy pill take to work?

The Wegovy pill gets to work in your body the moment you start taking it. However, it's completely normal for it to take a week or two for you to feel the effects of your treatment. This is especially true of the 1.5mg starter dose, which is designed to get your body used to the medication and reduce the risk of side effects.

This means you likely won't see the scales change immediately. But feeling fuller after smaller portions, thinking about food less, and finding it easier to manage cravings are still all signs the medication is working effectively.

How effective is the Wegovy pill for weight loss?

During the initial OASIS 4 clinical trial, patients on average lost around 17% of their starting weight while taking Wegovy pills. However, in a recent analysis of the trial, early responders (people who lost more than 10% of their starting body weight by week 16) actually lost 22% of their starting weight by the end of 64 weeks.

It's important to note that individual results can vary, and that these results were in a clinical trial environment. Some people lose less weight, while others lose more. For example, researchers found:

• 76% of people (8 in 10) lost at least 5% of their body weight.
• 60% of people (6 in 10) lost at least 10%.
• 47% of people (5 in 10) lost at least 15%.
• 28% of people (1 in 4) lost 20% or more.

Who can take the Wegovy pill

The eligibility criteria for Wegovy pills follows the same guidelines for Wegovy injections, meaning you’ll need:

• a BMI of 30 or above, or
• a BMI of 27 or above alongside a weight-related health condition like type 2 diabetes or high cholesterol

Before starting treatment, you need to complete a consultation, reviewed by one of our expert clinicians to make sure Wegovy pills are safe and suitable for you.

Wegovy pill price

The cost of Wegovy pills in the UK is as follows:

How to take the Wegovy pill

• Take your Wegovy pills first thing in the morning, on an empty stomach, before eating or drinking, or taking any other oral medication.
• Swallow whole with no more than 120ml of plain water. Not sparkling water, coffee, juice, or anything else.
• Wait at least 30 minutes before eating, drinking anything other than water, or taking other medications.
• Don't crush, chew, or split the tablet.
• Try to take it at the same time every morning so it becomes part of your routine.

What to do if you miss a dose

If you miss a dose, skip it and take your next tablet the following morning as normal. Don't double up, as it won't help and could increase side effects.

If you miss several doses in a row, speak to your prescriber before continuing, as they may want to review your dose.

What to do if you’re sick after taking your Wegovy tablet

If you throw up shortly after taking your Wegovy pill, you shouldn't take a second dose. Just wait to take your next scheduled dose the following day.

What happens if you stop taking the Wegovy pill?

If you stop taking the Wegovy pill, your appetite may return to its pre-treatment levels. However, the lifestyle changes that the tablet unlocked, like healthier eating habits and increased movement, can help you maintain and manage your weight.

Wegovy pill dosing schedule

Just like Wegovy injections, Wegovy pills use a titration process. This means you’ll gradually increase your dose each month (if suitable) to give your body time to adjust and reduce any potential side effects.

Your prescriber will advise you when it’s best to increase your dose based on how well you’re tolerating the medicine and your progress so far.

Below is an example of what your dosing schedule could look like:

Wegovy pills vs Wegovy injections

If you’re at the start of your weight loss journey, you may be wondering which treatment is right for you: the Wegovy pill or the Wegovy injection. The answer all depends on what you want from your medication:

Can I switch from Wegovy injections to pills?

It’s completely possible to switch from Wegovy injections to pills. Your dose will depend on which injection strength you're currently on. For example, if you're on the 2.4mg injection, you'd move to the 25mg pill.

Any switch should always be done under clinical supervision. You can find which dose you can safely switch to below:

While 25mg is the highest dose of the Wegovy pill, on average it's not as effective as the maximum 7.2mg injection. It is, however, slightly more effective than the 2.4mg injection, and may be a more convenient treatment option depending on your preferences.

Can I take Wegovy pills and injections at the same time?

No, you shouldn't use Wegovy pills and injections at the same time. It won't help you lose more weight but will put you at risk of overdosing your medication while increasing the chance of side effects. 

Is the Wegovy pill safe?

Wegovy pills have now been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK and the Food and Drug Administration (FDA) in the US, based on clinical trial data from hundreds of adults who are overweight or living with obesity.

Like any medication, they carry potential side effects and aren't right for everyone. But for people who meet the eligibility criteria, they're considered safe and effective when used as directed and under the supervision of a healthcare professional.

For more information on Wegovy pill side effects, please read the patient information leaflet.

How long do Wegovy pill side effects last?

For most people, the initial common side effects last between 1-4 weeks. They'll normally go away on their own as your body gets used to the medication but may come back when you increase your dose.

Managing your side effects

The most common Wegovy pill side effects can usually be managed by:

• eating plain foods, like rice and crackers
• avoiding foods that are fatty or oily
• eating smaller portions, more regularly
• Making sure you drink plenty of water to stay hydrated
• keeping moving to help your digestion

You can also take over-the-counter treatments, like painkillers and anti-sickness medications, to ease your symptoms if needed.

When to seek medical help

Contact your GP or prescriber or seek urgent medical help if you experience any of the following:

• Pancreatitis: severe stomach pain that won't go away, with or without nausea or vomiting. The pain may also spread to your back.
• Gallbladder problems (like gallstones): pain in your upper stomach, fever, yellowing of the skin or eyes, or clay-coloured stools.
• Low blood sugar (hypoglycaemia): Particularly if you also take insulin or sulfonylureas. Signs include dizziness, blurred vision, anxiety, sweating, slurred speech, shakiness, confusion, a fast heartbeat or feeling jittery.
• Dehydration and kidney problems: persistent nausea, vomiting, or diarrhoea can lead to dehydration, which can affect your kidneys. Make sure you're drinking plenty of fluids.
• Serious allergic reaction: swelling of the face, lips, tongue or throat, difficulty breathing or swallowing, severe rash or itching, fainting, or a very rapid heartbeat.
• Changes in vision: if you have type 2 diabetes and notice any changes in your vision, speak to your doctor.
• Increased heart rate: your heart feels like it's racing or pounding at rest, and it lasts for several minutes.

Who shouldn’t take Wegovy pills

You shouldn’t take Wegovy pills if:

• you're allergic to semaglutide or any of the other listed ingredients
• you've previously had a serious allergic reaction to semaglutide or any of the ingredients in Wegovy
• you or a close family member has ever had medullary thyroid carcinoma (MTC), a type of thyroid cancer
• you have multiple endocrine neoplasia syndrome type 2 (MEN 2)
• you are pregnant or breastfeeding

Tell your prescriber before starting if you:

• have or have had problems with your pancreas or kidneys
• have type 2 diabetes with a history of diabetic retinopathy
• are due to have surgery or a procedure involving anaesthesia
• are planning to become pregnant, as Wegovy may harm your unborn baby, so you should stop taking it at least two months before trying to conceive
• are planning to breastfeed, as it isn't recommended while taking Wegovy pills

Tell your prescriber about all medications you take, including prescription medicines, over-the-counter treatments, vitamins and supplements. Wegovy can affect how some medicines work, and some medicines can affect how Wegovy works.

This is especially important if you take diabetes medications like insulin or sulfonylureas, as using Wegovy alongside these treatments increases your risk of hypoglycaemia.

How to store Wegovy pills

Store your tablets in their original packaging, in a dry place away from moisture. This means you should avoid keeping them in the bathroom if it gets hot and steamy.
