Wegovy Pill

What is the Wegovy (Semaglutide) Pill?

The Wegovy pill is the oral form of the well-known Wegovy weight loss injection and contains the same active ingredient, semaglutide. It offers a convenient alternative to injections, making it a useful medication for people who can’t or don’t like the idea of using needles.

Wegovy weight loss pills were approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in June 2026, making them the first GLP-1 receptor agonist to be licensed for weight loss in tablet form. Wegovy tablets should be taken daily in the morning on an empty stomach. You will begin on a low dose that gradually increases until you reach the maintenance level of 25 mg. Clinical trials have shown that the treatment can help people lose an average of 16.6% over 64 weeks, making it comparable to the weekly injections.  

What is the Wegovy Pill Used For?

Much like semaglutide injections, the Wegovy pill is prescribed to support weight loss when taken alongside a balanced diet, increased physical activity, and other positive lifestyle changes. The tablets are not designed to be a quick fix, however, and will work best when you are eating well and being more active. 

Additional Benefits of Wegovy Tablets

In addition to potential weight loss, Wegovy semaglutide pills offer several other benefits. For example, clinical trials have found that people using Wegovy tablets experienced improvements in risk factors such as waist circumference and blood pressure, despite not being licensed for these purposes.

Wegovy pills and injections are also the only weight loss treatments proven to reduce the risk of major cardiovascular events, such as heart attack and stroke, in adults with established cardiovascular disease. This is after the MHRA approved semaglutide for use for this purpose.

Finally, semaglutide does not interact with oral contraceptives such as the combined pill or mini pill, meaning there is no need for women of childbearing age to switch to a non-oral form of contraception (such as the contraceptive patch, vaginal ring, or condoms). This makes semaglutide different to Mounjaro’s active ingredient, tirzepatide, which can reduce the effectiveness of oral contraceptives. That being said, you may need to use additional forms of contraception, such as condoms, if you experience Wegovy pill side effects such as vomiting or diarrhoea. 

How Does the Wegovy Pill Work?

The Wegovy pill contains the active ingredient semaglutide, a GLP-1 receptor agonist. It works by mimicking the naturally occurring GLP-1 hormone (which helps regulate blood sugar), activating receptors in the brain to help you feel satisfied for longer and reduce hunger and cravings.

Wegovy tablets help support weight loss in several ways, including:

• Helping you feel fuller faster during meals
• Suppressing your appetite
• Reducing ‘food noise’, the urge to continuously think about food
• Making you feel fuller for longer after eating
• Finding it easier to eat less without feeling deprived
• Regulating blood sugar levels to help prevent blood sugar spikes and cravings

The main difference in how the Wegovy pill works compared to the injections is how the medication is absorbed into the body. The injections are administered subcutaneously and are absorbed into the bloodstream, whereas the tablets have to pass through the digestive system first.

This process is facilitated by a carrier molecule known as salcaprozate sodium (SNAC), which is included in every Wegovy pill. SNAC is designed to protect the medicine from stomach acid and enzymes, while temporarily increasing local absorption into the bloodstream, allowing it to work similarly to injections. Without this ingredient, almost none of the medication would be absorbed from the tablet.   

How Long Does the Wegovy Pill Take to Work?

The Wegovy semaglutide pill can start working on your appetite and cravings within a few days to a few weeks after starting treatment, though it may take several weeks to notice significant weight loss. You might see a reduction in food noise and a greater feeling of satiety relatively quickly; however, the most substantial weight loss is likely to happen once you reach the maintenance dose after around 13 weeks. 

How Effective are Wegovy Pills?

The OASIS 4 clinical trial found that a daily 25 mg dose of Novo Nordisk’s Wegovy pill can lead to an average body weight reduction of 16.6% after 64 weeks, compared to 2.7% when using a placebo. This makes it comparable to the 17.5% weight loss achievable with the 2.4 mg Wegovy injection and slightly lower than the 20.7% weight loss with the 7.2 mg injection seen in the STEP UP trial.

Other results from the OASIS 4 study were as follows:

• 79.2% of participants lost at least 5% of their body weight
• 63% had a reduction of at least 10%
• 50% experienced a reduction of 15% or more
• 29.7% lost 20% or more

Meanwhile, a secondary analysis of the trial found that early responders (those who lost more than 10% of their body weight by week 10) lost an average of 21.6% of their body weight by week 64, indicating the potential for significant results. People who lost more than 7.5% of their starting weight by week 10 managed to lose an average of 20.3% by week 64.  

It’s important to note, however, that everyone’s weight loss journey is different. Your results may vary depending on your individual circumstances. 

How to Take the Wegovy Pill

Wegovy weight loss pills should be taken exactly as prescribed by a clinician, as they are specifically designed to ensure the medication works as effectively as possible.

To take the Wegovy pill, follow these instructions:

• Take the Wegovy tablet first thing in the morning on an empty stomach after a fasting period of at least 8 hours
• Swallow one pill whole. Ensure that you don’t chew, crush, or dissolve it 
• Take it with no more than 120ml of plain water. Don’t use it with tea, coffee, sparkling drinks, or any other beverage 
• Wait at least 30 minutes before eating, drinking, or taking any other medication

It’s important that the Wegovy tablet is taken this way so that the active ingredient (semaglutide) is protected from digestion and can reach the bloodstream, where it can travel to and activate GLP-1 receptors in the brain. 

How Often to Take the Wegovy Weight Loss Pill

The oral Wegovy pill is designed to be taken once per day in the morning. This makes it different from semaglutide injections, which are administered weekly according to a set dosing schedule. As with all weight loss treatments, consistency is key to achieving sustainable results. It’s therefore recommended to take the Wegovy tablet at the same time each day. 

What If You Miss a Wegovy Pill

If you forget to take a Wegovy tablet, skip the missed dose and take your normal pill the next day. Do not double up to make up for a missed dose, as this won’t help and could exacerbate side effects.

Should you miss several doses in a row, it’s recommended to speak to your prescriber, as they may want to review your dose to determine if it is still suitable to take. 

What If You Take Too Many Wegovy Tablets

If you take more Wegovy pills than you should, inform your doctor or clinician straight away. You may experience side effects such as nausea (feeling sick).

If You Stop Taking Wegovy Pills

Don’t stop taking the Wegovy pill without consulting your clinician or a doctor beforehand. They will be able to understand your difficulties and circumstances, and could recommend an alternative solution that’s more suitable for you.

Wegovy Pill Dosage Schedule

Much like semaglutide injections, Wegovy tablets follow a recommended dosage schedule that starts with a low-strength tablet and titrates up to a maintenance dose over a set period of time. The Wegovy pill dosage schedule is as follows:

If you experience side effects from the Wegovy pill, your clinician may advise that you stay on a lower dose for a longer period of time so your body can adjust to the medication. Remember that everyone’s journey is different and the suggested Wegovy dosage schedule is just a recommendation. Exactly how you reach your goals will be unique to you. 

Wegovy Pill Side Effects and Cautions

Like all medications, Wegovy weight loss pills can cause adverse reactions, both mild and serious. It’s therefore essential to have a clear understanding of what you could expect, so you can make a more informed decision about whether the treatment is right for you. If you’re ever unsure, consult your clinician before starting the medicine. 

Side Effects of Wegovy Pills 

Wegovy pill side effects can vary in frequency and duration, with more common reactions usually fading over a short time. Some people may not experience any adverse effects at all. Either way, it’s a good idea to know what may happen and how to deal with them.

Potential side effects of Wegovy tablets include:
 

If you experience any Wegovy pill side effects, you can report them to the MHRA’s Yellow Card scheme. 

How Long Do Wegovy Pill Side Effects Last? 

Wegovy pill side effects typically occur at the start of treatment and as your dosage increases. They can last from a few days to a few weeks and will usually improve as your body adjusts to the treatment. Thankfully, they tend to be mild and usually easy to manage at home.

You can deal with the side effects of Wegovy semaglutide tablets by doing the following:

• Resting well
• Eating smaller, more frequent meals
• Staying well hydrated 
• Eating bland, plain foods 
• Taking over-the-counter painkillers like paracetamol for headaches or mild stomach discomfort

If you experience side effects that worsen, don’t improve after a few weeks, or prevent you from carrying out your usual activities, consult a clinician for further advice. 

Serious Wegovy Pill Side Effects

If you experience any of the following serious Wegovy pill side effects, it’s important to get immediate medical assistance from your clinician or GP:

• Gallbladder issues: Pain in your upper stomach, yellowing of the skin or eyes, fever, or clay-coloured stools
• Dehydration and kidney problems: Ensure you drink plenty of fluids, as persistent nausea, diarrhoea, or vomiting can lead to dehydration and kidney issues
• Hypoglycaemia (low blood sugar): Dizziness, blurred vision, sweating, anxiety, slurred speech, confusion, feeling jittery
• Pancreatitis: Severe stomach pain that won’t go away. May also spread to your back 
• Changes in vision: Important if you have type 2 diabetes and notice any changes in your vision, or if you experience symptoms like sudden blindness or a rapid deterioration in eyesight
• Serious allergic reaction: Difficulty breathing or swallowing, severe rash or itching, swelling of the face, lips, tongue or throat, fainting, or a very rapid heartbeat

More information regarding the side effects of Wegovy pills can be found in the Patient Information Leaflet that comes with the medication. 

Who Can Take Wegovy Tablets?

Wegovy pills are suitable for adults who have a BMI (body mass index) of 30 or above, or between 27 and 30 with weight-related health conditions such as high blood pressure, heart disease, type 2 diabetes, or high cholesterol. Although highly effective for weight loss, the treatment may not be suitable for everyone, as some medical conditions or other medicines can reduce its effectiveness or make it potentially unsafe.

For example, you should not take the Wegovy pill if you:

• Are allergic to semaglutide or any of the other ingredients in the tablets
• Have previously had a serious allergic reaction to semaglutide or other Wegovy ingredients
• Are pregnant or breastfeeding

When to Inform Your Doctor Before Taking Wegovy Pills

Wegovy semaglutide pills may not be suitable for everyone, including some older adults and individuals with complex health conditions. It’s therefore important to tell your clinician or doctor before starting treatment if you:

• Are over 85
• Have type 2 diabetes
• Have severe heart failure
• Have severe liver or kidney problems
• Have diabetic eye problems 
• Experience sudden changes in eyesight
• Are scheduled to have surgery or other procedures that use sedation or anaesthesia
• Have delayed stomach emptying (gastroparesis)
• Have inflammation of the pancreas
• Have low blood sugar (hypoglycaemia) 

Wegovy Tablets and Other Medications

It’s possible for some medications to interact with the Wegovy pill and make it unsuitable to take. As a result, it’s important to notify your prescriber of any other treatments you may be taking, including over-the-counter or herbal remedies, so they can ensure Wegovy tablets are safe for you to use. This is especially important if you are taking the following medicines:

• Diabetes treatments, including insulin or sulfonylureas
• Levothyroxine for thyroid disease
• Warfarin or similar medications that are designed to reduce blood clotting

Although semaglutide itself does not affect oral contraceptives, if you experience Wegovy pill side effects such as severe diarrhoea or vomiting, your protection from pregnancy may be impacted. This is because absorption of the pills can be affected. According to the NHS, what you should do if you encounter these symptoms depends on whether you are taking the combined pill or progestogen-only pill (mini pill). 

Pregnancy and Breastfeeding

Wegovy pills should not be used if you are pregnant, as it’s not known if the medication can affect your unborn baby. It’s therefore important to use contraception while taking the medication. If you become pregnant while taking semaglutide, talk to your clinician or doctor immediately, as your treatment will need to be changed. Should you wish to become pregnant, seek medical advice as you will have to stop using Wegovy tablets at least 2 months in advance.

You should also not use Wegovy tablets if you are breastfeeding, as the medication can pass through breastmilk. It is not known how this may affect your baby. 

Comparing Wegovy Pills and Wegovy Injections

Wegovy weight loss pills are the oral version of Wegovy injections. Both contain the same active ingredient and work in the same way to help you along your journey. However, there are some key differences that you should be aware of:
 

Can I Switch from Wegovy Injections to Wegovy Tablets?

Yes, it’s possible to switch from Wegovy injections to Wegovy pills following a consultation with our prescribers. This is because any change in medication must be done under clinical supervision. If you do make the change, your starting tablet dose will depend on your current injection strength. 

Switching from Wegovy injections to Wegovy pills can offer potential benefits and drawbacks. For example, the average weight loss with the tablets is lower than that of the 7.2 mg injection (though more comparable to the 2.4 mg). However, the tablets may offer a more convenient treatment option depending on your preferences and schedule.  

Comparing Wegovy Tablets and Mounjaro

Mounjaro is another popular weight loss injection. It contains a different active ingredient and affects additional receptors in the brain to help you lose weight. The main differences between the two treatments are as follows:

Can I Switch From Mounjaro to Wegovy Tablets?

Yes, you can switch from Mounjaro to Wegovy pills under medical supervision. This is to determine whether Wegovy tablets will be safe and suitable for you to take. Your starting dose of Wegovy tablets will be determined by your current Mounjaro strength and how you are coping with side effects. 

Where to Buy the Wegovy Pill in the UK

Wegovy weight loss pills are currently unavailable in the UK, so they're not available to buy. However, because the treatment has now been licensed by the MHRA, it will soon be available for purchase. 

Can You Buy the Wegovy Pill Over the Counter?

No, you will not be able to buy the Wegovy pill over the counter, as it is classed as a prescription-only medication (POM), just like semaglutide injections. You will therefore need a prescription from a licensed clinician before obtaining the treatment, so they can determine whether it is safe and suitable for you. 

Is the Wegovy Pill on the NHS?

No, the Wegovy pill is not available on the NHS and can only be purchased via private providers or registered online pharmacies. Since it is a new treatment, access to it on the NHS will depend on guidance from the National Institute for Health and Care Excellence (NICE).

It is currently possible to obtain Wegovy injections on the NHS, up to a dose of 2.4 mg. 

Can You Buy the Wegovy Pill Online?

Yes, you will be able to buy the Wegovy pill online from trusted pharmacies, such as Prescription Doctor, once it becomes available. Simply complete our brief questionnaire so our experienced clinicians can see whether it is suitable for your circumstances.
