How long does Wegovy take to work?
Wegovy is an effective weight loss medication that can produce excellent results when combined with broader lifestyle changes based on nutrition and exercise. If you’re referred to a weight management programme like Oviva, you could receive an NHS prescription for Wegovy. So when does Wegovy start working, and at what dose do weight loss results begin to show?
Key Takeaways
- Wegovy starts to work inside the body quickly, but it’ll take time to build up to a stable level, and noticeable results may take a while.
- On average, people on Wegovy lose 2% to 3% of their body weight in the first month.
- Weight loss differs for everyone, and results may take longer.
- Oviva can help you implement behavioural changes concerning food and exercise, which can maximise your weight loss outcomes while you’re taking Wegovy.
How long does Wegovy take to work?
When you start taking Wegovy, the medication should begin to work inside the body within a few days of your first injection.
However, you’ll start on a low dose, and it takes 16 to 20 weeks to build up to the maintenance dose. Feeling a change in your appetite could take several days or weeks.
So, how long does Wegovy take to work for weight loss? Well, many people experience initial weight loss in the first few weeks of treatment.
A STEP 1 clinical trial (Wilding et al.) found the average weight loss achieved during the first four weeks of treatment with Wegovy was 2% to 3% of total body weight.
But it’s not uncommon for the effects of weight loss to take longer. This is partly because the Wegovy dosing schedule focuses on gradual increases over several months.
At what dose does Wegovy start working?
The Wegovy dosing schedule begins at 0.25 mg once per week, and this low initial dosage should stay the same for the first four weeks of treatment.
From there, the dosage increases gradually in four-week intervals before you eventually reach the maintenance dose, which is usually 2.4 mg per week.
Wegovy can start producing weight loss benefits at the starting dose (0.25mg), but it’s typical for weight loss results and appetite suppression to become more apparent as the dosage increases.
Generally, weight loss effects increase when dosage increases. Therefore, you can expect the best results once you reach the 2.4 mg/week maintenance dose.
How long does it take to notice weight loss on Wegovy?
The amount of time it takes for your weight loss to become noticeable will depend on your starting weight and the amount of weight you can lose in the early stages of treatment. Your height and body type can also determine how noticeable early weight loss is.
Many people will experience weight loss in the first four weeks of treatment, which could be 2% to 3% of their total body weight. As this increases towards 10% of your body weight in the months beyond, you’ll likely start noticing changes.
This may include changes in your appearance, mobility or fitness levels. However, exact results will vary from one person to the next.

When should my Wegovy dosage increase?
When you first begin treatment with Wegovy, you’ll receive an initial dosage of 0.25 mg, taken once a week using a simple injection pen that can be self-administered. This low initial dosage is taken for four weeks so your body can get used to the medication.
The dosage escalation then progresses as follows:
- Weeks 1-4: 0.25 mg/week
- Weeks 5–8: 0.5 mg/week
- Weeks 9-12: 1 mg/week
- Weeks 13-16: 1.7 mg/week
- Week 16 and beyond: 2.4 mg/week
Healthcare providers may recommend either 1.7 mg/week or a higher 2.4 mg/week dose as the final maintenance dose. The aim is to reach the maximum dose and manage side effects, as the best and most widely studied results are associated with the 2.4 mg/week dosage.
However, your maintenance dose may depend on various factors, including the severity of any side effects you experience and your weight loss results on the 1.7 mg/week dosage.
