Frequently asked questions

How long does one Wegovy pen last?

Each pre-filled Wegovy pen contains four once-weekly doses, lasting one month (28 days). Store at room temperature after first use and dispose of pens in a sharps bin after the final dose.

Does Wegovy need to be refrigerated?

Yes, Wegovy must be kept in the fridge (between 2°C and 8°C) before first use. After opening, you can store the pen at room temperature (up to 30°C) for up to 42 days.

What if I miss a Wegovy dose?

If you miss your weekly Wegovy injection, you can take the missed dose if your next scheduled dose is more than 48 hours away.

If your next dose is less than 48 hours away, skip the missed dose and take your next injection on your regular day. Do not double up to make up for a missed dose.

Can I drink alcohol on Wegovy?

Yes, you can drink alcohol while taking Wegovy. There are no known direct interactions between Wegovy (semaglutide) and alcohol.

Can I get Wegovy on the NHS?

Yes, Wegovy (semaglutide) is available on the NHS, but only for patients who meet specific clinical guidelines. You may be eligible if you have a BMI of 35 or higher or a BMI between 30 and 34.9 with a weight-related health condition like type 2 diabetes, high blood pressure, or heart disease. The treatment must also be prescribed through a specialist NHS weight management service.

How much does Wegovy cost per month in the UK?

At Chelsea Slimming Clinic, monthly Wegovy costs range from £129.99/month for the starting dose to £249.99/month for the maintenance dose.

Is Wegovy the same as Ozempic?

Wegovy and Ozempic contain the same active ingredient, semaglutide, but they’re used for different purposes. Wegovy is specifically approved for weight loss in people with obesity or weight-related health issues. At the same time, Ozempic is licensed to manage type 2 diabetes by lowering blood sugar levels.

How do I switch from Ozempic to Wegovy?

If you're currently using Ozempic for weight loss, you can switch to Wegovy without restarting the dose from the beginning. In most cases, you can either continue at the same strength or step up to the next Wegovy dose if you've been stable on your current dose for at least 4 weeks. For example:

  • Ozempic 0.5mg → Wegovy 0.5mg or 1.0mg
  • Ozempic 1.0mg → Wegovy 1.7mg
  • Ozempic 2.0mg → Wegovy 2.0mg or 2.4mg

A short break (a few weeks) may allow you to resume where you left off. Still, if the gap is longer, it’s safer to restart at a lower Wegovy dose to minimise side effects like nausea.

How do I switch from Saxenda to Wegovy?

Switching from Saxenda to Wegovy is straightforward, but the doses are not equivalent. Both medications are GLP-1 receptor agonists but contain different active ingredients and are taken differently. Saxenda is a daily injection, while Wegovy is a weekly.

If you’re currently on 3.0mg of Saxenda daily, you can switch to Wegovy 0.5mg weekly. Starting at this dose helps reduce the risk of side effects like nausea. After 4 weeks, you can increase to the next Wegovy dose.

If you take less than 3.0mg of Saxenda or have a long break, start with Wegovy 0.25mg and follow the usual dose increase schedule.

Wegovy vs Mounjaro: What’s the Difference?

Wegovy and Mounjaro are weekly weight loss injections that have shown strong results in clinical trials. However, Mounjaro (tripeptide) has been shown to offer greater average weight loss—around 22% after 72 weeks—compared to Wegovy’s 15%.
