Weight loss medications

Eli Lilly, the manufacturer of Mounjaro, has increased the price of all dose strengths in the UK to align with prices across mainland Europe. This change means that in the UK, Wegovy is now a more cost-effective GLP-1 treatment option for weight management.
We know changes like this can feel unexpected and can lead to frustration. But our priority is to help you continue your weight loss journey with minimal disruption and find the treatment that best supports your health goals and fits your lifestyle.

Yes. With the recent price increase for Mounjaro, Wegovy has become the more cost-effective option for weight loss and obesity management with prices starting from £99.99 a month.
Switching medications is a normal and common occurrence — it’s something medical professionals do regularly for conditions like high blood pressure or high cholesterol, whether it's to reduce side effects or lower costs. We’ll work with you to find the treatment that’s right for your needs, budget and goals.
Read our guide to switching
Mild or moderate side effects? These are usually symptoms like mild nausea or a minor headache that don’t stop you from going about your day and often improve over time.
Severe or worrying side effects? If you experience any of the following, stop taking your medication immediately.
  • Severe, persistent stomach pain
    • Severe means:
      • It’s so intense (around 8 or more out of 10) that you can’t focus on anything else
      • It makes it nearly impossible to handle normal daily tasks (like walking, getting dressed, or eating)
      • It doesn’t improve with over-the-counter pain relief or rest
      • It radiates to your back or underneath your right ribcage or your right shoulder
      • You also have severe vomiting (3 or more times a day, or having coffee grounds or blood in vomit)
    • These symptoms could indicate pancreatitis, a serious condition that requires urgent medical attention.
  • Difficulty breathing, or swelling of the lips, tongue, or throat
    • These could be signs of a severe allergic reaction, which can be life-threatening.
  • Severe pain underneath your right ribcage that may spread to your shoulder or back
    • This may be accompanied by vomiting, a high temperature or a rapid heartbeat.
    • These symptoms could suggest acute gallbladder problems.
If you notice any of these symptoms, call 999 or head to A&E right away.
If you have any questions about side effects or how to manage them, we’re here to support you.
Some people may notice a lump or mild swelling at the injection site. This is usually harmless and should resolve on its own.
Rotating your injection site and using proper technique can help minimise irritation.
If a lump at the injection site persists, worsens or becomes painful, please contact your GP.
It’s important to remember that the uncomfortable but common side effects tend to improve with time as your body adjusts to the medication.
Contact us for advice on adjusting your dose — our experts might advise you to remain on a lower dose for longer.
You can report any side effect you experience through the government Yellow Card Scheme.

Mounjaro:

  • If you miss a dose, take it as soon as possible within 4 days. If more than 4 days have passed, skip the missed dose and take your next dose on the usual day.
  • Never take a double dose to make up for a missed dose.
  • If you’ve missed multiple doses, contact us to discuss restarting your treatment.

Wegovy:

  • If you miss a dose, take it as soon as possible within 5 days. If more than 5 days have passed, skip the missed dose and take your next dose on the usual day.
  • Never take a double dose to make up for a missed dose.
  • If you’ve missed multiple doses, contact us to discuss restarting your treatment.
If you become unwell with the cold or flu while taking weight loss medication like Wegovy or Mounjaro, treat your illness as you normally would — stay hydrated, rest and take over-the-counter medications like cold and flu tablets if needed.
Because these medications can increase the risk of dehydration, make sure to drink extra fluids — even more than you normally would — especially if you have a fever, vomiting or diarrhoea.
If you are experiencing severe diarrhoea that lasts longer than a few days, or vomiting that prevents you from keeping down food or fluids, you should stop taking your weight loss medication and call 111 for medical advice. Make sure you tell the healthcare provider that you have been taking weight loss medication.
It is important to remember that weight loss with medications like Wegovy and Mounjaro is a gradual process.
These medications begin working soon after your first dose by reducing appetite and regulating blood sugar levels. They stay in the body for about a week, which is why they are taken once weekly. To minimise side effects and help your body adjust, the dose is increased gradually every four weeks in a process called titration.
While some people may experience weight loss within the first few weeks, Wegovy and Mounjaro are designed as long-term treatments for obesity, rather than quick fixes. Weight loss is more likely to be steady over many months, and everyone's journey will be different — so don’t worry if your results aren’t immediate.
Clinical trials show that you can lose up to 15–20% of your body weight, but this can take over a year.
Be sure to reassess your lifestyle to make sure you are in a calorie deficit. This is when you burn more calories than you consume, and is key for weight loss.
If you’ve been taking your medication for several weeks and haven't noticed any changes in appetite or weight, please contact us to discuss further.
If your current dose is working and you’re happy with your progress, you can stay on that dose.
You start on the lowest dose of weight loss medication, which usually increases every 4 weeks. If you’re experiencing side effects or you’re satisfied with your current weight loss, you can stay on a lower dose.
You always have the option to increase your dose when you feel ready.
If you’re scheduled for surgery requiring general anaesthesia, please mention during your pre-operative assessment that you’re taking a GLP-1 medication (e.g. Mounjaro or Wegovy). Also, contact us so we can update your records.
Side effects can vary from person to person, but they’re most common when you first start Mounjaro or Wegovy or when your dose increases.
The good news is that mild side effects usually settle down within a few days to a couple of weeks, as your body adjusts to the medication. If you are experiencing more troublesome or lingering side effects, please contact us for further support.
When you increase your dose, side effects can sometimes reappear or worsen. This is simply because your body needs time to adjust to the higher dose. The good news is that these usually improve over time.

If you are of childbearing age and sexually active, you should use contraception while taking Mounjaro.

No, we advise patients to not use Mounjaro while breastfeeding. It is not yet known whether Mounjaro passes into breast milk, so the risk to a breastfed baby can’t be ruled out.

Some people taking GLP-1 medications, such as semaglutide (Wegovy) or tirzepatide (Mounjaro), may notice changes in their vaginal bleeding. This can happen more often if they are also using hormone replacement therapy (HRT). Although this is increasingly observed, official guidance is still limited.

These changes might happen because GLP-1 medications slow down digestion. This can affect how your body absorbs hormone treatments — especially HRT taken as tablets, particularly oral progestogens. There don’t appear to be the same issues with hormone patches or intrauterine devices (like the Mirena coil). Weight loss and other body changes may also play a role.

This kind of bleeding is usually not serious, but it’s important to tell your doctor if you experience new, heavy or ongoing bleeding. They can check for other causes and may suggest adjusting your HRT or carrying out further tests if needed.
