About Wegovy

Wegovy is a medicine for weight loss and weight maintenance that contains the active substance semaglutide. This medicine works by acting on receptors in the brain that control your appetite, causing you to feel fuller and less hungry. The solution is injected underneath the skin surface using a pre-filled pen. Wegovy should be used with a reduced calorie meal plan and increased physical activity.

This medicine is used in adults, who have:

  • A BMI of 30 kg/m² or greater (obesity).
  • A BMI of 27 kg/m² and less than 30 kg/m² (overweight) and weightrelated health problems (such as diabetes, high blood pressure (hypertension), abnormal levels of fats in the blood, obstructive sleep apnoea, or a history of heart attack, stroke or vascular problems).

Wegovy is used together with diet and physical activity for weight management in adolescents ages 12 years and above, who have:

  • Obesity, and
  • Body weight > 60 kg.

As an adolescent patient, you should only continue using Wegovy if you have lost at least 5% of your BMI after 12 weeks on the 2.4-mg dose or maximum tolerated dose.

How to use Wegovy

Wegovy is given as an injection under the skin (subcutaneous injection). Do not inject it into a vein or muscle. The best places to give the injection are the upper arms, stomach or upper legs. Before you use the pen for the first time, ask your doctor, pharmacist or nurse how to use it.

Detailed instructions for use can be found in the package leaflet. Follow these instructions closely.


Your dose should be determined by a doctor. The general guidelines for use are as follows:

Adults The recommended dose is 2.4 mg once weekly, taken on the same day. Your treatment will start at a low dose which will be gradually increased over 16 weeks of treatment as follows:

  • When you first start using Wegovy, the starting dose is 0.25 mg once weekly.
  • Your doctor will instruct you to gradually increase your dose every four weeks until you reach the recommended dose of 2.4 mg once weekly.
  • Once you reach the recommended dose of 2.4 mg, do not increase this dose further.
  • During treatment with Wegovy, you may experience nausea or vomiting. Ask your doctor to delay increasing your dose or to lower your dose to the previous level until your body adjusts and the symptoms improve.

You will most likely be told to follow the table below:

  • Week 1–4: 0.25 mg once weekly
  • Week 5–8: 0.5 mg once weekly
  • Week 9–12: 1 mg once weekly
  • Week 13–16: 1.7 mg once weekly
  • From week 17: 2.4 mg once weekly

For adolescents, the same dose escalation schedule as for adults should be applied (see above). The dose should be increased until 2.4 mg (maintenance dose) or maximum tolerated dose has been reached. Weekly doses higher than 2.4 mg are not recommended.


This medicine does not interact with alcohol.

Wegovy is not likely to affect your reaction time. For diabetics using this medicine in combination with a diabetes medicine, low blood sugar (hypoglycaemia) may occur which may reduce your ability to concentrate. Do not drive or use machines if you feel dizzy or get any signs of low blood sugar.

If you use too much/forget to use/stop using Wegovy

If you use more Wegovy than you should, talk to your doctor straight away. You may feel sick (nausea) or be sick (vomiting), or have diarrhoea. These side effects can cause dehydration (loss of fluids).

If you forgot to inject a dose and:

  • it is five days or less since you should have used Wegovy, use it as soon as you remember. Then inject your next dose as usual on your scheduled day.
  • it is more than five days since you should have used Wegovy, skip the missed dose. Then inject your next dose as usual on your scheduled day.

Do not inject a double dose to make up for a forgotten dose.

Do not stop using Wegovy without talking to a doctor first.

Frequently asked questions

How does Wegovy work?
Wegovy contains the active ingredient semaglutide, a GLP-1 receptor agonist. GLP-1 is a hormone that supresses appetite and increases the feeling of fullness after eating. This makes people eat less, which in turn can lead to weight loss.

The injectable prescription medication Wegovy is used to treat people who are overweight or obese, with a body mass index (BMI) of 30 or higher.

It is also prescribed to people with a BMI of 27 or higher with weight-related health problems, such as type 2 diabetes or cardiovascular diseases.

Wegovy, also known as semaglutide, is not suitable for everyone. It should not be used by people with certain medication conditions, such as a kidney or liver disease, or by pregnant or breastfeeding women.
Are there any side effects or risks associated with Wegovy?
The most common side effects of Wegovy are nausea, vomiting, diarrhoea, constipation, stomachache, headache, dizziness, tiredness, changes in taste sensations, a general feeling of being unwell (malaise), and injection site reactions. These symptoms are usually mild and generally go away within a few weeks.

Serious side effects, such as pancreatitis, gallbladder disease and kidney problems, can occur while taking Wegovy, but they are rare.
How often and how long should Wegovy be used?
Wegovy is injected once a week. The duration of treatment varies per person. Most people use Wegovy for one year or longer. How long Wegovy is used depends on each person’s individual weight loss goals, and should be determined by a doctor.
Where can I buy Wegovy?
You can buy Wegovy from online services and pharmacies, provided you have a prescription for it from a doctor.
How much does Wegovy cost?
The cost of Wegovy can vary depending on several factors, including your location, your insurance coverage and the pharmacy rate. Some insurance providers cover the entire cost of Wegovy or part of it.
Are Wegovy and Ozempic the same?
