If you have recently been prescribed Wegovy or are considering it as a weight management option, understanding how dosing works is one of the most important steps you can take before starting treatment. Getting the dose right, and following the recommended schedule, can make a significant difference to both your results and your experience of side effects.
Wegovy (semaglutide) is a once-weekly injectable treatment licensed for weight management in adults with obesity or overweight when combined with a reduced-calorie diet and increased physical activity. Like many medications of its type, it is introduced gradually to allow the body to adjust.
If you would like to discuss whether Wegovy is suitable for you, contact us or book a consultation with the team at Mendus Pharmacy in Pembroke.
What Is Wegovy and How Does It Work?
Wegovy contains semaglutide, a GLP-1 receptor agonist that mimics a hormone naturally produced in the gut after eating. It works by:
- Reducing appetite by acting on receptors in the brain that regulate hunger
- Slowing gastric emptying, which helps you feel fuller for longer
- Influencing blood sugar regulation, which may reduce cravings
- Supporting a sustained calorie deficit when used alongside lifestyle changes
Wegovy is intended for use in adults with a BMI of 30 or above, or a BMI of 27 or above in those with at least one weight-related health condition such as high blood pressure or type 2 diabetes.
The Wegovy Dosing Schedule
Wegovy follows a structured dose escalation schedule. The gradual increase is designed to minimise side effects, particularly nausea and gastrointestinal symptoms, while allowing the body to adjust over time.
| Phase | Weekly Dose | Duration | Purpose |
|---|---|---|---|
| Phase 1 | 0.25 mg | Weeks 1 to 4 | Initial introduction, allow body to adjust |
| Phase 2 | 0.5 mg | Weeks 5 to 8 | Gradual increase, monitor tolerance |
| Phase 3 | 1 mg | Weeks 9 to 12 | Continued escalation |
| Phase 4 | 1.7 mg | Weeks 13 to 16 | Approaching maintenance dose |
| Maintenance | 2.4 mg | Week 17 onwards | Full therapeutic dose for ongoing weight management |
It is important to follow this schedule as directed by your prescribing clinician. Increasing the dose too quickly can raise the risk of side effects, while staying at a lower dose for longer may be recommended if tolerance is a concern.
How to Administer Wegovy
Wegovy is administered via a pre-filled injection pen and is given once weekly on the same day each week. Key points to be aware of include:
- It is injected subcutaneously, meaning just beneath the skin
- Suitable injection sites include the abdomen, upper thigh, or upper arm
- The injection site should be rotated each week to avoid skin irritation
- Wegovy can be taken with or without food
- If a dose is missed and it is within five days of the scheduled day, take it as soon as possible
- If more than five days have passed since the missed dose, skip it and resume on your next scheduled day
- Never take two doses in one week to make up for a missed one
What to Expect at Each Stage of Dosing
Knowing what is normal at each phase of the Wegovy dosing schedule can help you feel more confident throughout treatment.
Weeks 1 to 4 (0.25 mg): This is a starter dose and is not expected to produce significant weight loss results at this stage. Some people experience mild nausea or digestive changes as their body begins to adjust.
Weeks 5 to 12 (0.5 mg to 1 mg): As the dose increases, appetite suppression typically becomes more noticeable. Side effects may briefly increase following each dose change before settling again.
Weeks 13 to 16 (1.7 mg): Most people are approaching their maintenance dose by this stage. Weight loss progress may become more consistent, and many side effects will have reduced compared to earlier phases.
Week 17 onwards (2.4 mg): This is the full therapeutic maintenance dose. At this stage, the focus shifts to sustaining progress through continued treatment and lifestyle adjustments.
Safety Considerations and Who Should Not Use Wegovy
Wegovy is not suitable for everyone. A healthcare professional will assess your suitability before prescribing. The following factors may affect eligibility:
- A personal or family history of medullary thyroid carcinoma
- A history of pancreatitis
- Pregnancy or breastfeeding
- Certain other medical conditions or medications that may interact with semaglutide
- Type 1 diabetes (Wegovy is not indicated for this)
Common side effects include nausea, vomiting, diarrhoea, constipation, and headache. These are most common during the early stages of treatment and typically improve over time. If side effects are severe or persistent, it is important to seek medical advice promptly.
Wegovy Dosing: Frequently Asked Questions
Click on each question to reveal the answers you are looking for:
Can I increase my Wegovy dose faster than the schedule suggests?
The dose escalation schedule is designed to reduce the risk of side effects. It is not recommended to increase your dose ahead of schedule without explicit guidance from your prescribing clinician. Doing so may increase the likelihood of nausea and other gastrointestinal symptoms.
What happens if I miss a Wegovy dose?
If you miss a dose and it has been five days or fewer since your scheduled injection day, take it as soon as you remember. If more than five days have passed, skip the missed dose and continue with your next scheduled injection. Never take two doses in the same week.
How long does it take for Wegovy to start working?
The starter doses (0.25 mg and 0.5 mg) are introductory phases and may not produce noticeable weight loss results. Most people begin to see more meaningful progress once they reach higher doses, particularly from around week nine onwards. Results vary between individuals.
Do I have to stay on the 2.4 mg dose once I reach it?
The 2.4 mg dose is the recommended maintenance dose for most people. If this dose is not well tolerated, your clinician may recommend temporarily staying at 1.7 mg before progressing. Any changes to your dose should be made under professional guidance.
Can I stop Wegovy suddenly?
You should not stop taking Wegovy without speaking to a healthcare professional first. Stopping treatment may affect your progress, and your clinician will be able to advise on the most appropriate approach based on your individual circumstances.
Where should I inject Wegovy?
Wegovy should be injected subcutaneously into the abdomen, upper thigh, or upper arm. It is important to rotate the injection site each week. Avoid injecting into the same spot repeatedly, as this can cause skin irritation or changes in the tissue beneath the skin.
