You can buy Wegovy in the following doses: 0.25mg, 0.5mg, 1mg, 1.7mg, and the highest dose of 2.4mg. Wegovy is an appetite suppressant that keeps you fuller for longer, reduces cravings, and limits food intake to support weight loss. Each Wegovy pen contains four doses, enough for one injection per week. This means you’ll need one pen per month to stay on track with your weight loss treatment.

Wegovy directions
Always use your Wegovy pen exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. For further instructions on how to use your Wegovy pen, including how to dispose of an empty pen and needles, please read our ‘How to take Wegovy’ guide.
Can you take half a dose of Wegovy?
Some people try to stretch their Wegovy pen by halving the dose, but we don’t recommend this or provide advice on it. Wegovy’s set doses exist for a reason. Splitting it may reduce its effectiveness, lead to inaccurate dosing, or even result in using expired medication. Plus, it can cause a treatment gap, which might delay or cancel your next order for safety reasons.
Wegovy side effects
Like all medicines, Wegovy may cause side effects in some people, but these won’t affect everybody. Common side effects may include:
- Headaches
- Nausea & vomiting
- Diarrhoea & constipation
For more information on side effects, including potentially serious side effects, refer to the patient information leaflet or read our detailed ‘Wegovy side effects’ guide for helpful advice on how to relieve symptoms of Wegovy.
Wegovy warnings
- Do not use Wegovy if you’re allergic to semaglutide or any of the other listed ingredients.
- Wegovy is only suitable for adults aged 18 years and over.
- Do not use Wegovy if you are pregnant or breastfeeding. Contraception is recommended while using Wegovy.

Wegovy with food, drink & alcohol
Wegovy can be used with or without food. If you’re wondering about what you can and can’t eat while using Wegovy, read our ‘Wegovy diet’ guide, which also includes advice about drinking alcohol during your treatment.

Lifestyle changes for Wegovy
Is Wegovy the same thing as Ozempic?
Wegovy and Ozempic are two medications which use the same active ingredient for different purposes.
They are both manufactured by Novo Nordisk, which holds the patent for both medications at the moment. Ozempic is a medication for patients with type 2 diabetes that helps you to control your blood sugar, and it can be used alone or alongside other medicines like insulin or metformin.
As they both contain semaglutide, these medications work similarly, but that doesn’t mean you can use them interchangeably.
Ozempic is used in different dose sizes to Wegovy, with Wegovy often being prescribed in higher amounts, so if you’re already taking Ozempic for type 2 diabetes you won’t be able to take Wegovy as well, as this could cause an overdose of the active ingredient.
Is a sharps bin included with this product?
Yes, we can supply sharps bins you can use to safely dispose of Wegovy or Saxenda pens.
When you have completed your consultation with our prescribers, the option to include a sharps bin with your order will be there for you to select.
Depending on your order size, we may be able to give you your sharps bin for free, but there may be a charge for smaller orders.
Once you have your sharps bin, you will need to contact your local council to organise collection and its safe disposal when your bin is full.
What is the difference between Wegovy and Saxenda?
Saxenda is another brand of weight loss injection that is very similar to Wegovy.
They work in a similar way, but use different active ingredients and have different dosage sizes. Saxenda uses an active ingredient called liraglutide, which is part of the same group of medicines as semaglutide — GLP-1 receptor agonists.
Saxenda needs to be injected once a day, whereas Wegovy only needs to be injected once a week.
Saxenda pens also need you to set your dose manually and insert a new needle for each dose, Wegovy doesn’t need you to do either of these as each pen is only used once.
The final big difference is that Wegovy has been shown to be much more effective than Saxenda in clinical trials.
With Saxenda you can lose 5% of your starting weight within 12 weeks of taking its maximum dose, but clinical trials of Wegovy have found that patients lose an average of 15% of their starting weight.
Can I drink alcohol while I’m taking Wegovy?
You can drink alcohol while you’re taking Wegovy, it shouldn’t affect the way this treatment works.
However, we always recommend that you drink in moderation and try to drink water or another soft drink between alcoholic drinks to help you stay hydrated.
Something else you should look out for is the calorie content in alcoholic drinks.
Alcoholic drinks often contain a lot more calories than you might expect, so drinking a lot can interfere with your weight loss simply by increasing your calorie intake.
Do Wegovy pens need replacement needles?
Unlike Saxenda, Wegovy pens don’t need you to replace their needles after each use.
This is because Wegovy pens are single-use only, so you won’t need to measure out a dose manually and won’t need to worry about putting a new needle onto your pen.
This is one of the reasons that patients prefer this treatment to Saxenda, as you don’t need to manage dosing or needles by yourself, making the whole process simpler.
How long do Wegovy weight loss injections take to work?
Wegovy injections get to work in your system right away, but that doesn’t mean that the pounds will fall off within a couple of days.
Clinical trials of Wegovy have shown that patients typically lose 15% of their starting body weight during their treatment, but how quickly this happens depends on the number of calories you’re eating every day.
Wegovy works by helping to control your appetite and reduce food cravings, making it easier for you to stick to the low-calorie diet you’ll need to lose weight.
A healthy rate of weight loss is generally considered to be 1 - 2lbs a week, so you may want to use this as a rule of thumb when considering your weight loss goals.
Do I need a prescription for this medication?
You do need a prescription for this medication in the UK.
Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.
When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.
Just like an in-person consultation with your GP, our doctors will assess your answers to their questions and write a prescription for the treatment they think will be best for you.
You’ll then be able to pay for your medication and we’ll send it out to you quickly and in discreet packaging.
Why do you need to know my BMI?
Weight loss treatments are only suitable for use in people with a BMI (body mass index) of 30 or above, or a BMI of 27 or above in those who have weight-related medical conditions. If your BMI is lower than this, then our prescribers won’t be able to recommend this product as a treatment for you.
Starting to take weight loss medication when you have a lower BMI could mean that you lose too much weight and become underweight, which can also contribute to some medical conditions.
