A qualified clinician can advise you as to whether you are eligible for a weight loss treatment. It’s assessed on the basis of your Body Mass Index (BMI) which is a screening tool that uses height and weight to estimate total body fat. Your BMI result will be displayed as a number within a category:
If you’re adult and have a BMI ≥ 30 kg/m2, or a BMI ≥ 27 kg/m2 alongside a weight-related condition, you’ll be eligible.
Clinical trials give an indication of how much people have lost in standardised research on commonly used treatments.
Mounjaro – People on Mounjaro have been shown to lose 20.2% of their body weight over 72 weeks.1
Wegovy – In the same trial, people on Wegovy lost 13.7%.(1) In a recent trial of a new higher dose of 7.2mg, nearly half of those taking it lost 20% or more of their body weight.(2)
Nevolat – When used correctly along with a change in diet and increase in exercise, people can expect to lose around 5-10% of their starting body weight.
Liraglutide – In a clinical trial, two thirds of people taking liraglutide lost at least 5% of their body weight.(3)

As with all medicines, you may get some side effects while taking weight loss injections. This is most likely when you first start taking treatment or after you’ve increased your dose. These side effects tend to go away within a few weeks and ease over time. Speak to your doctor if side effects aren’t getting better.
To find out more about any side effects you can expect for your weight loss injection, read the patient information leaflet that comes with your medicine.
Very common and common side effects of weight loss injections include:
Serious weight loss injection side effects can include:
If you experience side effects talk to your doctor or other healthcare professional. This includes any possible side effects not listed in the package leaflet. Call 999 or go to A&E if you get symptoms of any serious side effects.
Weight loss injections work by imitating natural hormones in your body that regulate your appetite and hunger levels. Mounjaro, Wegovy and Saxenda act on the hormone GLP-1 and Mounjaro acts on a second hormone too; GIP.
These hormones are released after you eat, attaching to receptors that send signals to your brain telling it that you’ve eaten and are full. Weight loss injections imitate these hormones, so you’ll feel fuller even while eating less. They also reduce how quickly your stomach empties after eating, which keeps you feeling full and so less likely get hunger urges.
If the missed Mounjaro® dose was 4 days ago or less:
If more than 4 days have passed since the missed dose:
Important dosing safety rule: Do not take two Mounjaro® doses within 3 days of each other.
Yes, you can drink alcohol while taking your weight loss treatment, but it should be in moderation. Alcohol and Mounjaro or Wegovy don’t specifically interact, but combining the two can still pose potential risks. GLP-1 medicines work by slowing gastric emptying and reducing appetite. This can sometimes cause nausea or stomach discomfort. And alcohol may make this worse.
In addition, drinking large amounts of alcohol can lead to side effects, such as low blood sugar. This can cause you to consume extra calories, which obviously negatively impacts your weight loss slowing your progress.
Women should try to limit themselves to one drink per day and men should not drink more than two. Try to avoid drinking on an empty stomach to reduce the risk of nausea and stomach irritation.
Since GLP-1s work by suppressing appetite, one of the first things you may notice after stopping taking your treatment is that you feel more hungry again. This is obviously going to encourage you to consume more food. It’s one of the reasons why people often quickly gain some of the weight they’ve successfully lost. It important to realise that obesity is a chronic condition and can’t be cured. It needs long-term treatment.
Speak to your doctor if you’re considering coming off your treatment and they can advise about the best way of doing so to support you in maintaining the weight loss you’ve worked so hard for. During your time on the treatment, if you’ve managed to make some healthy lifestyle changes too, it will be easier to keep the weight off.
A. Wegovy is not meant for a short-term or cosmetic weight loss – either as a pill or injection. Health experts strongly advise against using Wegovy as a quick-fix to get “beach body” ready.
The starting dose is a 1.5mg tablet once a day for one month. If your healthcare advisor agrees, the dose would then generally increase each month until the recommended maximum dose of 25mg daily. It can take several months to see the full benefits and weight may go back on after you stop the medication.
If you’re taking a 2.4mg semaglutide injection, it’s possible to switch to daily semaglutide 25mg tablets. You should always consult a healthcare professional before switching.
If you’re pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your healthcare professional for advice before taking Wegovy®. It shouldn’t be used during pregnancy, as it’s not known if it affects your unborn baby.
If you are planning to become pregnant, discuss how to change your treatment with your healthcare professional as you should stop using Wegovy® at least 2 months in advance. If you become pregnant while using Wegovy®, talk to your healthcare professional straight away, as your treatment will need to be changed.
Don’t use this medicine if you’re breast-feeding, as the medicine passes into breast milk, and it’s not known how it affects your baby.
The Wegovy® pill can fit into your morning: just Sip & Go.
Take it on an empty stomach in the morning with water (up to 120 mL). Makre sure that you swallow the pill whole and wait 30 minutes before eating, drinking, or taking other oral medications. That gives the medicine time to be properly absorbed.
Set yourself some reminders to help you take the Wegovy® pill the same way every day.
Your body needs time to absorb the semaglutide peptide medicine in the Wegovy® pill. Wegovy® tablets include something called SNAC, (salcaprozate sodium) which helps the semaglutide survive in the stomach long enough to be absorbed into your bloodstream. Taking the Wegovy® pill on an empty stomach with the 30-minute window gives the medication time to get absorbed without being interrupted.
To protect your medicine, store your pills at room temperature (68 °F to 77 °F) in a dry place. It’s important to keep them in the original bottle and keep it tightly closed until you are ready to take your pill.
