Wegovy Dosing Schedule: A Complete Guide To Proper Administration

Starting a weight loss journey with Wegovy can feel empowering, but using an injectable medication for the first time can also be a little intimidating. It helps to understand how it works and what to expect from your treatment plan, from dosage information to side effects and everything in between.

In this guide, we'll walk you through how Wegovy dosing works, what your dosing schedule might look like, and common questions about using Wegovy, so you can work towards your weight loss goals with confidence. We’ll focus on Wegovy injections for this guide, as Wegovy Pill (a once-daily oral tablet) follows a different dosing schedule.

Article summary:

• Wegovy is the brand name for semaglutide, made by manufacturer Novo Nordisk. The medication belongs to a class of drugs known as GLP-1 receptor agonists, or glucagon-like peptide-1 receptor agonists. Originally developed for managing type 2 diabetes, it’s now used to support weight loss by mimicking a naturally occurring hormone that helps regulate appetite and blood sugar levels. [1]
• Wegovy is administered as a weekly subcutaneous injection, i.e. under the skin. You’ll start on the lowest dose and may gradually increase as your body adjusts. [1] Each dose is reviewed every 4 weeks by your healthcare provider, to make sure you’re tolerating side effects and to check in on your progress.
• Wegovy injections can only be prescribed for weight management if you’re eligible. In the UK, Wegovy is licensed for adults with a body mass index (BMI) of 30 or higher, which is classified as obesity, or a BMI of 27 or higher if you also have at least one weight-related health condition such as high blood pressure, type 2 diabetes, or high cholesterol. However, it may also be prescribed “off-label” if you have a BMI over 25 and have other weight-related health conditions. [1]

Wegovy dosing chart

Wegovy is an effective, clinically backed medication for weight loss and weight management, but it must be taken correctly to be effective.

Each Wegovy dose is administered once a week via subcutaneous injection, meaning it’s injected just under your skin. Common injection sites include the back of your upper arm, your lower tummy or thigh, and you should take it on the same day each week. [2]

To help your body adjust and to reduce the risk of side effects, you’ll get a treatment plan that gradually increases your doses over several weeks before reaching a maintenance dose suitable for you.

The following dosing chart shows the licensed dose escalation you might experience before reaching your maintenance dose. But, there’s never any pressure to increase your dose if you’re happy with your ongoing progress.

Each Wegovy dose comes in colour-coded, pre-filled pens for ease. Depending on your dose, you’ll either use the Wegovy FlexTouch pen (0.25mg, 0.5mg, 1mg, 1.7mg and 2.4mg) or the Wegovy 7.2mg single-dose pen.

Wegovy dosing schedule

Because everybody is different, not everyone will move up the dosing schedule at the same rate. When you select your next dose, your request will be assessed by a clinician to check if it’s safe and appropriate for you to continue with your chosen dose of Wegovy.

You can’t step up your dose early, but you can stay on a lower dose for longer if you need or choose to. For example, if side effects become difficult to manage at a particular dose, you may decide to pause dose increases or reduce your dosage temporarily. The goal is to find the dose that is most effective and comfortable for you.

You can support your weight loss with Wegovy injections by staying consistent with your weekly injections, sticking to a healthy diet and staying active. [3]

Available doses

There are currently 6 Wegovy doses available for weight management:

• Wegovy 0.25mg
• Wegovy 0.5mg
• Wegovy 1mg
• Wegovy 1.7mg
• Wegovy 2.4mg
• Wegovy 7.2mg

Starting dose

The starting dose of Wegovy is 0.25mg for the first 4 weeks. This is the lowest dose of Wegovy available.

The official dosing schedule for Wegovy involves increasing your dose every 4 weeks, but that doesn’t mean that you have to. Some people find that a lower dose works well for them, so they choose to stay on it for longer. Other people may take longer to adjust to side effects. There’s no need to increase your dose simply because you’ve reached the end of a 4-week period.

The aim is to find the dose that works best for you. This means finding a balance between making progress with your weight loss, and keeping your side effects manageable. For some people this means staying on a lower dose for longer, which is nothing to worry about.

Maintenance dose

Once you’ve reached a weight you’re happy at, it’s time to find your maintenance dose. As its name suggests, this is the dose that helps you to maintain your new, healthier weight.

Exactly what your maintenance dose will be will depend on your individual response to treatment. You may find that a lower dose of Wegovy is enough to keep your weight stable once you reach your target, and it may be necessary to alter your dose more than once to find the right maintenance dose for you.

Maximum dose

The maximum dose of Wegovy is 7.2mg, taken once a week.

What to expect at each stage

So now you know what your treatment journey might look like, you may wonder what to expect at each dose level.

First, a quick lesson on how Wegovy works. Wegovy promotes weight loss by mimicking the natural GLP-1 hormone that’s released after you eat to reduce hunger, regulate blood sugar, slow down digestion, and increase feelings of fullness. This should make it easier to eat less and lose weight over time.

In a major clinical trial, overweight or obese adults who used 7.2mg Wegovy injections weekly lost an average of 20.7% of their body weight over 72 weeks. [6]

However, it’s not a quick fix. You’ll most likely notice small behavioural changes in the early weeks of your treatment before you see any changes on the scale. That doesn’t mean your treatment isn’t working, it’s just your body’s natural response to the medication.

Here’s a guide to what you can expect from month to month, and what your Wegovy results may look like. But don’t panic if your journey looks different. Weight loss plateaus happen, bodies respond differently, and medication is just one piece of the puzzle.

Month 1

During the first few weeks of your Wegovy treatment, it’s not unusual to experience mild side effects as your body adjusts. These are usually digestive symptoms like nausea or constipation, and often subside as your system becomes more accustomed to the medication. [5] If you’re struggling with them, reach out to your prescriber to find out about other medications, such as anti-nausea drugs, that could help.

Studies show you can expect to lose 2-3% of your weight in the first month, but remember, everyone’s journey is different. [6]

Month 2

By month 2, you might start to notice your appetite changing. You may feel fuller for longer, notice less food noise, or be satisfied with smaller portions. [7] These are all signs your treatment is working. According to clinical trial data, you may lose an average of 4% of your starting weight by this point. [6]

Month 3

In month 3, you may notice a more consistent reduction in appetite and fewer cravings. You could see more visible weight loss, too. [8] Your clothes may feel looser, with clinical trials showing you could lose an average of 6-7% of your starting weight by the third month of treatment. [6]

Month 4+

Wherever you are in your titration schedule, you should be noticing continued, gradual weight loss (we recommend aiming for 0.5-1kg a week), stable appetite suppression and be feeling more confident. Once you’ve reached a weight you’re happy with, it’s time to think about maintaining your results with a long-term maintenance dose.

How movement can support you at every dose

When it comes to adding movement to support your weight loss journey, you really need to be guided by your own health and physical abilities. For some people this means starting to gradually increase their step count each week, to help you become more mobile and active. For people who already regularly exercise, this could mean continuing with your usual activities, or adding to them.

In an ideal world, you should aim for 20–30 minutes of activity, 4–5 days a week, including warm-up and cool-down stretches to reduce injury risk, as well as 2 strength training sessions per week. These can be built up gradually. [9]

However, just know that moving more, in any capacity, will be beneficial for managing your side effects, as well as supporting you in achieving your weight loss goals.

Doses and side effects

When it comes to prescription weight loss medications like Wegovy, some people may experience side effects, especially during the early weeks of use or when dose strengths are being increased. Most side effects are temporary and manageable.

You’ll find more details on these in your patient information leaflet that’s included with your medication, but below is a table of Wegovy side effects, grouped by how common they are: [1]

Side effects of Wegovy

Very common (may occur in more than 1 in 10 people)

• Constipation
• Diarrhoea
• Fatigue
• Headache
• Nausea (feeling sick)
• Stomach pain
• Vomiting

Common (may occur in up to 1 in 10 people)

• Unusual skin sensations (dysaesthesia)
• Bloating
• Burping
• Changed sense of taste (dysgeusia)
• Dizziness
• Flatulence
• Gallstones
• Gastritis
• Hair loss
• Heartburn
• Indigestion
• Injection site reactions (redness, swelling)

Uncommon (may occur in fewer than 1 in 100 people)

• Increased heart rate (you may notice this as a racing, pounding or fluttering feeling in your chest)
• Kidney stones
• Low blood sugar (also known as hypoglycaemia)
• Low blood pressure
• Acute pancreatitis

Rare (may occur in up to 1 in 1000 people)

• Severe allergic reaction (anaphylaxis or angioedema). This can present as difficulty breathing, swelling of lips, tongue and/or throat, difficulty swallowing, rapid heartbeat.

Simple strategies like eating smaller meals, staying well hydrated, avoiding fatty or greasy foods, and exercising may help ease them. Rotating your injection site each week or injecting into a slightly different spot each time can also help to reduce the risk of skin irritation. [10]

Your healthcare provider may also make suggestions about managing symptoms, adjusting your dose, or suggesting medications that can help.

Most common side effects and how to manage them

The most commonly reported side effects of Wegovy injections include nausea, constipation, diarrhoea, and vomiting. These digestive symptoms often occur as your body adjusts to the medication or an increase in dose. Most people find that these side effects reduce and disappear over time, especially once a maintenance dose is reached.

To manage digestive symptoms:

• Eat slowly and mindfully to avoid overeating
• Stick to bland, low-fat foods during periods of discomfort
• Stay hydrated, especially if you experience diarrhoea or vomiting
• Limit alcohol and high-sugar foods, which can worsen symptoms

Other very common side effects include headaches, stomach pain and fatigue.

To manage headaches:

• Drink plenty of fluids (water, herbal teas)
• Use over-the-counter pain relief such as paracetamol, if appropriate
• Apply a warm or cold compress
• Aim for 7–9 hours of sleep each night
• Consider adding magnesium citrate, which may help reduce headaches and support energy levels

To manage stomach pain:

There are different types of stomach pain, and how you manage it depends on the type you’re experiencing. Refer to the booklet that came with your medication for more details, but you may find the following helps:

• Eat smaller meals more frequently
• Chew your food slowly
• Try peppermint tea
• Go for a gentle walk
• Hold a heat pack against your stomach

To manage fatigue:

• Make sure you’re eating enough nutrient-dense food to meet your energy needs.
• Ensure adequate intake of key vitamins and minerals. Vitamin B12 (found in meat, fish, eggs and dairy) plays an important role in energy production. Low levels can contribute to fatigue.
• Vitamin D also supports overall health. Sunlight is the main source, but it can also be found in oily fish, red meat, liver and egg yolks. If you’re getting sun exposure, wear SPF 50.
• Check your iron levels if fatigue persists. Iron is found in foods such as red meat, liver, beans and pulses.
• Exercise regularly at a manageable intensity to support energy levels.
• Aim for 7–9 hours of sleep each night and try to keep a consistent sleep schedule.
• Create a sleep environment that is cool, dark and quiet.
• Consider magnesium citrate supplements, which may help support energy levels.

Rarely, more serious side effects can occur for Wegovy users, such as:

• Severe abdominal pain (which could indicate pancreatitis)
• Signs of allergic reactions such as swelling, rash, or difficulty breathing
• Vision changes or symptoms of diabetic retinopathy (in people with type 2 diabetes)
• Signs of kidney problems, such as reduced urination or swelling in your legs or feet

If you experience any of these, contact 999 or head to A&E. Serious side effects are uncommon, but it's important to look out for them and seek help immediately. [4] [11] [12]

Wegovy dosing FAQs

We’ve put some of your most common questions about Wegovy dosing to our Head of Medical Affairs, Dr. Sophie Dix.

Who decides when your dose increases?

“You’re in control of your weight loss journey. You should track your weight loss progress and monitor your side effects, to help you decide when to increase your dose. When you order your next prescription, a clinician will review your details and decide if it’s safe and appropriate for you to move up to the next dose, or if you should stay on the dose you’re currently taking.

“Skipping doses or adjusting your schedule may disrupt your progress and even reduce how well your medication works over time. Being consistent with your treatment is the best way to achieve your weight loss goals.”

When should your dose increase?

“Wegovy doses may be increased gradually every 4 weeks until you reach a maintenance dose. However, everyone is different and some people choose to stay on a lower dose for longer, usually to help them manage side effects or because they are losing weight at a rate they are happy with.”

Do I have to increase my dose?

“No, there’s no need to increase your dose if you don’t want to. Some people find they tolerate side effects better on a lower dose, or may see the results they want without moving to a higher dosage. The aim is not to reach the maximum dose available, it’s to find the right dose for you.”

What is titration?

“Titration is the medical process of slowly increasing your medication dose over time to help your body adjust and reduce side effects. [1] Titration also makes it easier for you to see how your body responds to Wegovy, so you can decide which dose is working for you. This will help ensure that you’re on the correct dose, which will help to make your treatment plan more sustainable for you in the long term.”

What is a maintenance dose?

“Your maintenance dose is the dose you may decide to stay on once you’ve reached your target weight. Everyone’s maintenance dose is different, because it’s based on a careful balance of helping you to maintain your new, healthier weight and manage any side effects you may be experiencing.”

“Remember, healthy habits also matter. A balanced diet, good hydration, and regular exercise all play crucial roles in supporting your weight loss long term.”

What should I do if I miss a dose?

“You should aim to take your dose of Wegovy on the same day of the week. This ensures a consistent level of medication in your system.”

“But, if you miss a dose, you can take it within 5 days of the scheduled dose. If more than 5 days have passed, skip the dose and stick to your normal dosing schedule. Never take a double dose to make up for missed injections.”

How many doses are in a Wegovy pen?

“There are 4 doses in each Wegovy pen. If you have any medication left over in your pen, don’t take more. This is there for priming, and not for injecting. It’s sometimes referred to as the ‘golden dose’ or ‘fifth dose’ and taken by people trying to squeeze an additional week out of their Wegovy pen. This isn’t safe or recommended.”

Is it possible to split my Wegovy dose?

“No, and it’s not recommended. You should take each dose exactly as prescribed so that you can keep track of exactly how much you’re taking.”

What should I do if I can't tolerate my new dose?

“If you’re finding your side effects are more severe when you step up your dose, this can be normal as it takes time for your body to adjust. Contact our team to discuss reducing your dose, and visit our Weight Loss Health Guide for advice on how to manage your side effects at home, and when to seek additional medical advice.”

At MedExpress, we offer online consultations with regular clinical check-ins, and a range of weight loss treatments including Mounjaro Pen, Wegovy Pen, Wegovy Pill and Foundayo and our team can help you find the right treatment for you.
