- Decreasing the amount of food eaten
- Reducing craving for food
- Supporting reduced calorie intake

The very long half-life of Semaglutide, which is one week, enables the medicine to be taken once a week.

Wegovy 0.25mg Dosage for Weight Loss
0.25mg once weekly is the starting dose for Wegovy weight-management treatment.
The usual dose-escalation schedule is:
| Treatment period | Weekly dose |
| Weeks 1–4 | 0.25mg |
| Weeks 5–8 | 0.5mg |
| Weeks 9–12 | 1mg |
| Weeks 13–16 | 1.7mg |
| Maintenance | 2.4mg |
There is a 16-week period during which the amount is being increased gradually so as to limit the possibility of experiencing gastrointestinal side effects. If the person has a lot of stomach problems, then maybe the next dose increase would be put off until the symptoms subside.
The first week the dose of Wegovy 0.25mg is only for adults, not for regular use. Don’t raise the dose without a doctor’s or prescriber’s advice.
What If You Miss a Wegovy 0.25mg Dose?
If you miss your weekly dose, it should be administered as soon as possible within 5 days after the missed dose.
If more than 5 days have passed, skip the missed dose and take the next injection on your usual scheduled day.
If several doses are missed, your doctor may consider restarting treatment at a lower dose. Do not take two injections together to make up for a missed dose.
Possible Side Effects
The most common side effects of Wegovy are related to the digestive system.
Possible side effects include:
- Nausea
- Diarrhoea
- Constipation
- Vomiting
- Abdominal pain
- Indigestion
- Bloating
- Headache
- Dizziness
- Tiredness
- Injection-site reactions
Gastrointestinal (GI) symptoms are also especially common in patients who receive treatment at different dosage levels during the dose-escalation period. Nausea, diarrhoea, constipation and vomiting have been some of the most frequent GI adverse reactions experienced by patients participating in clinical studies.
The majority of these gastrointestinal adverse effects tend to be mild-to-moderate in intensity and may become more pronounced during dosage escalations. Contact your healthcare provider if you experience severe or prolonged abdominal discomfort that radiates into the region surrounding your back, since this can be an indication for acute pancreatitis.
It’s important to note that repeated vomiting or diarrhoea will lead to dehydration as well as affecting your kidney functions.
Precautions Before Using Wegovy 0.25mg
Tell your doctor before starting Wegovy if you have:
- A history of pancreatitis
- Severe gastrointestinal problems or delayed stomach emptying
- Kidney problems
- Liver problems
- Gallbladder disease or gallstones
- Diabetic retinopathy
- A previous serious allergic reaction to semaglutide
- Diabetes treated with insulin or sulfonylureas
- A planned surgery or procedure involving general anaesthesia or deep sedation
You shouldn’t use Semaglutide if you’re pregnant or plan on becoming pregnant.
Australian product information advises stopping Semaglutide at least two months prior to planned pregnancy due to its prolonged presence within the body.
Tell your healthcare team you’re using Wegovy if you have surgery or a procedure involving either general anaesthesia or deep sedation. This is because Semaglutide has been associated with an effect of slowing gastric emptying.
Wegovy 0.25mg and Other Medicines
You should tell your doctor if you take: all of your prescription medicines, including medicines for diabetes (such as insulin or sulfonylureas), any supplements or other treatments for weight management
The risk of hypoglycaemia increases when semaglutide is taken alongside insulin or sulfonylureas, which are types of medicine used to treat diabetes.
Your doctor might decide to reduce your doses of these medicines. Semaglutide can delay gastric emptying – how quickly food leaves your stomach and moves through your gut into your intestines. This could affect the way your body absorbs some medicines from your mouth to stomach. It could be important for medicines that need to be absorbed quickly by your gastrointestinal system.
You shouldn’t take Wegovy together with other semaglutide containing medicines or other GLP-1 receptor agonists unless you have been specifically advised to do so by your healthcare professional

Frequently Asked Questions
Is Wegovy 0.25mg enough to cause weight loss?
The 0.25mg dose is primarily used to start treatment and help the body adjust to semaglutide. Weight-management treatment is gradually increased to higher doses when appropriate. Individual weight-loss responses vary.
Why is Wegovy started at such a low dose?
Starting at 0.25mg helps improve tolerability. Semaglutide can cause nausea, vomiting, diarrhoea and constipation, particularly when treatment begins or the dose is increased. Gradual escalation is used to reduce the likelihood of these problems.
Can Wegovy 0.25mg be taken at night instead of in the morning?
Yes. Wegovy can be administered at any time of day, provided it is taken once weekly according to the prescribed schedule. It does not need to be taken with a meal.
How quickly does Wegovy start working on appetite?
Semaglutide begins acting on GLP-1 receptors after administration, but the noticeable effect on appetite can vary from person to person. The 0.25mg stage is mainly an introductory dose, so some people may notice only modest appetite changes during the first few weeks.
Can I change my weekly Wegovy injection day?
Yes. If necessary, the weekly injection day can be changed provided there are at least 72 hours between two doses. After changing the day, continue with a once-weekly schedule.
