Wegovy Tablets for Weight Loss: How They Work and What to Expect

October 08, 2026

Wegovy tablets offer eligible adults a new way to manage their weight without injections. They contain semaglutide, a GLP-1 medicine that can reduce hunger, increase feelings of fullness, and help people consume fewer calories.

Wegovy tablets are taken once daily and must be used alongside a reduced-calorie diet and increased physical activity. As a prescription-only medicine, they should only be supplied after a qualified healthcare professional confirms that treatment is safe and appropriate.

This guide explains how Wegovy tablets work, who may be eligible, how to take them, and what results and side effects patients may experience.

Quick Summary

• Wegovy tablets contain semaglutide.
• Take them once daily for weight management.
• The tablets help reduce hunger and food cravings.
• Treatment begins at a low dose that gradually increases.
• Take them after fasting for at least eight hours.
• Common side effects include nausea, diarrhea, constipation and vomiting.
• Wegovy tablets require a prescription and clinical assessment.
• Results vary, and healthy lifestyle changes remain important.

What Are Wegovy Tablets?

Wegovy tablets are a prescription weight-loss medicine containing semaglutide. They belong to a group of medicines called glucagon-like peptide-1 receptor agonists, commonly known as GLP-1 medicines.

The tablets are approved in the UK for weight loss and long-term weight management in eligible adults. Use them with a reduced-calorie diet and increased physical activity, not as a replacement for healthy lifestyle changes.

Unlike weekly weight-loss medicines, Wegovy tablets are taken by mouth once each day. However, they must be taken in a specific way to help the body absorb the medicine properly.

How Do Wegovy Tablets Work for Weight Loss?

Semaglutide works by mimicking the effects of GLP-1, a hormone the body naturally releases after eating.

GLP-1 acts on brain areas involved in appetite regulation. Wegovy tablets may support weight loss by helping patients:

• Feel full for longer after eating
• Experience less hunger between meals
• Reduce food cravings
• Control portion sizes
• Consume fewer calories

The medicine can also slow food movement through the stomach. This may contribute to longer-lasting fullness, although it can also cause digestive side effects.

Wegovy tablets do not directly burn fat. Weight loss occurs when reduced appetite helps a person maintain a lower calorie intake alongside appropriate dietary and physical activity changes.

Who May Be Eligible for Wegovy Tablets?

Wegovy tablets may be prescribed to adults with:

• A body mass index of 30 kg/m² or higher, classified as obesity; or
• A BMI between 27 kg/m² and under 30 kg/m², classified as overweight, together with at least one weight-related health condition

Relevant conditions may include high blood pressure, abnormal blood-fat levels, obstructive sleep apnoea, cardiovascular disease or problems with blood sugar regulation.

BMI is only one part of a clinical assessment. A prescriber will also consider:

• Medical history
• Current weight and health conditions
• Previous weight-management attempts
• Other medicines being taken
• Possible contraindications
• Pregnancy or breastfeeding
• The potential benefits and risks of treatment

Wegovy tablets are not suitable for everyone and should not be used solely for cosmetic weight loss.

How Should Wegovy Tablets Be Taken?

The way Wegovy tablets are taken can affect how much semaglutide the body absorbs.

According to the MHRA’s instructions, the tablet should be:

1. Taken once daily after fasting for at least eight hours.
2. Swallowed whole with a small sip of water.
3. Taken without food, tea, coffee or other drinks.
4. Wait at least 30 minutes before eating, drinking, or taking another oral medicine.

Do not split, crush or chew the tablet. Eating or drinking too soon after taking it can reduce the absorption of semaglutide and may make the medicine less effective.

Always follow the instructions provided by your prescriber and the patient information leaflet.

What Is the Wegovy Tablet Dosing Schedule?

Wegovy tablets usually begin at a low dose. The dose is gradually increased to help the body adjust and reduce the likelihood of digestive side effects.

The approved dose stages are:

• 1.5 mg once daily
• 4 mg once daily
• 9 mg once daily
• 25 mg once daily

Each dose stage generally lasts for a minimum of one month before the next increase. The 25 mg dose is the usual maintenance dose.

Your prescriber will determine the appropriate schedule. Do not increase your dose early or take more than prescribed. If side effects become difficult to manage, contact your healthcare provider instead of changing the dose yourself.

How Much Weight Can You Lose With Wegovy Tablets?

Results vary between individuals and cannot be guaranteed. Factors such as starting weight, diet, physical activity, treatment adherence, and individual response can all influence weight loss.

In the OASIS 4 clinical trial, adults receiving semaglutide 25 mg tablets alongside lifestyle support lost an average of approximately:

• 13.6% of their body weight after 64 weeks when all participants were included, regardless of whether they remained on treatment
• 16.6% when estimating results among participants who continued following treatment

The placebo groups lost approximately 2.4% and 2.7%, respectively. These are study averages and should not be interpreted as a guaranteed personal result. 

How Long Do Wegovy Tablets Take to Work?

Wegovy tablets begin affecting appetite after treatment starts, but visible weight loss usually develops gradually.

Some patients may notice reduced hunger or changes in portion size during the early stages. More meaningful changes in body weight generally require several weeks or months of consistent treatment.

The starting doses are primarily intended to help the body adjust to semaglutide. Greater effects may become noticeable as the dose increases, but patients should not rush the dosing schedule.

A prescriber should regularly review:

• Weight-loss progress
• Side effects
• Treatment adherence
• Nutrition and physical activity
• Changes in other health conditions
• Whether continuing treatment remains appropriate

What Side Effects Can Wegovy Tablets Cause?

Like all medicines, Wegovy tablets can cause side effects, although not everyone will experience them.

The most common side effects affect the digestive system and may include:

• Nausea
• Vomiting
• Diarrhoea
• Constipation
• Abdominal discomfort
• Reduced appetite

These effects may be more noticeable when starting treatment or increasing the dose. They often improve as the body adjusts, but persistent or severe symptoms require medical advice.

Eating smaller meals, avoiding very rich or fatty foods, and drinking enough fluids may help some patients manage mild digestive symptoms.

What Serious Symptoms Require Medical Attention?

Seek prompt medical advice if you develop severe or persistent side effects.

Symptoms requiring urgent assessment may include:

• Severe, persistent abdominal pain
• Repeated vomiting or inability to keep fluids down
• Signs of dehydration, such as dizziness or reduced urination
• Symptoms of a serious allergic reaction
• Sudden changes or loss of vision
• Severe upper-abdominal pain, particularly with fever or yellowing of the skin or eyes

Always read the patient information leaflet for a complete list of warnings and side effects.

Can Wegovy Tablets Be Taken With Other Medicines?

Wegovy tablets can affect how quickly the stomach empties, which may influence the absorption or effects of some oral medicines.

Before starting treatment, tell your prescriber about everything you take, including:

• Prescription medicines
• Over-the-counter products
• Vitamins and supplements
• Herbal remedies
• Diabetes medicines
• Other weight-management treatments

Do not use Wegovy tablets with another medicine containing semaglutide or another GLP-1 medicine unless specifically instructed by an appropriate healthcare professional.

Because no other oral medicines should generally be taken for at least 30 minutes after a Wegovy tablet, discuss your morning medication schedule with the prescriber.

What Should You Eat While Taking Wegovy Tablets?

There is no single diet that every patient must follow, but Wegovy tablets should be combined with a nutritionally balanced, reduced-calorie eating plan.

Helpful habits may include:

• Eating smaller portions
• Choosing lean sources of protein
• Including vegetables, fruit, and fiber-rich foods
• Drinking enough water
• Eating slowly and stopping when comfortably full
• Limiting highly processed and calorie-dense foods
• Reducing greasy or fatty meals if they worsen nausea
• Avoiding excessive alcohol

Rapid weight loss or an overly restrictive diet can make it difficult to consume enough protein, vitamins, and minerals. Seek professional dietary advice if you are unsure how to eat safely during treatment.

Is Exercise Necessary While Taking Wegovy Tablets?

Wegovy tablets are approved for use alongside increased physical activity. Exercise can support weight management while helping preserve muscle, improve fitness, and protect general health.

A suitable routine may combine:

• Walking or other aerobic activity
• Strength or resistance exercises
• Flexibility and mobility work
• Gradual increases in everyday movement

Choose activities appropriate for your health and fitness level. Speak to a healthcare professional before beginning a new exercise programme if you have an existing medical condition or have previously been inactive.

What Happens If You Miss a Dose?

Follow the missed-dose instructions supplied with the medicine or contact your prescriber or pharmacist for advice.

Do not take two doses together to compensate for a missed tablet. Taking extra medicine could increase the risk of side effects.

Using a daily reminder may help you follow the treatment schedule consistently.

Can You Drink Coffee After Taking Wegovy Tablets?

You should wait at least 30 minutes after taking a Wegovy tablet before drinking coffee, tea, or any other beverage.

The tablet should be swallowed after an overnight fast with only a small sip of water. Eating or drinking during the following 30 minutes can reduce the absorption of semaglutide.

Patients who normally have coffee immediately after waking may need to adjust their morning routine.

Can Wegovy Tablets Be Used During Pregnancy?

Wegovy tablets should not be used during pregnancy. Weight loss is not recommended during pregnancy, and semaglutide may pose a risk to the developing baby.

Tell your prescriber if you:

• Are pregnant
• Think you may be pregnant
• Are trying to become pregnant
• Are breastfeeding
• Plan to become pregnant

Your healthcare professional can advise when treatment should be stopped before a planned pregnancy and discuss suitable alternatives.

What Happens When You Stop Taking Wegovy Tablets?

Appetite may increase after treatment is stopped, and some people may regain weight. Obesity is a long-term health condition, so maintaining weight loss often requires continued dietary, activity and behavioral support.

Do not stop Wegovy tablets without speaking to your prescriber. They can help develop a long-term plan based on your progress, health, and reasons for discontinuing treatment.
