FAQs about weight loss medications
Our medical team are based in the UK and registered with the General Medical Council and General Pharmaceutical Council.
Weight loss tablets work by blocking the absorption of some of the fat in your diet. As a result, your body absorbs fewer calories from the fat you eat, which can help you lose weight over time.
Injectable GLP-1 treatments, like Wegovy® and Mounjaro®, are more effective as they help control your appetite. They mimic a natural hormone in your body called GLP-1, which signals to your brain that you’re full and should stop eating. By increasing this signal, GLP-1s can regulate your blood sugar and keep you feeling fuller for longer.
Both oral and injectable treatments are designed to be used as part of a weight loss plan that includes a healthy diet and regular exercise.
Injectable GLP-1 treatments like Wegovy and Mounjaro help regulate appetite and improve feelings of fullness, supporting steady, sustainable weight loss when used alongside healthy lifestyle changes.
Mounjaro® stands out as the most effective dual acting GIP + GLP-1.
In 72 weeks, people taking Mounjaro 15mg in a clinical study lost an average of 22.5% of their body weight when taken as directed. This means that someone who weighs 100kg may lose 22.5kg on average in 72 weeks (1 year, 5 months).*
What about Wegovy? In 72 weeks, people taking Wegovy 7.2mg in a clinical study lost an average of 20.7% of their body weight when taken as directed. This means that someone who weighs 100kg may lose 20.7kg on average in 72 weeks (1 year, 5 months).**
These are examples only. It is not a prediction of individual results.
*SURMOUNT-1, 72-week study of adults with obesity using Mounjaro (tirzepatide 15mg). Individual results vary.
**STEP UP, 72-week study of adults with obesity using Wegovy (semaglutide 7.2mg). Individual results vary.
Oral weight loss treatments, like orlistat, are clinically proven to help you lose 50% more weight than just dieting alone. In clinical trials, almost twice as many people lost 10% or more of their body weight in one year when taking orlistat, compared to those who were dieting without treatment.
Alli is designed to be used alongside a support programme. For every 2kg your efforts help you lose, Alli can help you lose 1kg more. It works by blocking 25% of the fat you eat from being absorbed, so it makes your healthy choices even healthier.
Mounjaro® and Wegovy® are injectable pens you use once a week.
They’re easy to use and give you the right dose without needing measurements or syringes. You can inject them into your arm, leg, or abdomen. The pens have a small, fine needle for a nearly painless injection just under the skin surface. They come with clear instructions and links to video demonstrations.
Take one pill with a drink at each main meal that contains fat.
You should take Orlistat (Alli®) up to three times a day alongside a reduced-calorie diet. Each time you take it, your meal should contain no more than around 30% of calories from fat.
GLP-1s, or glucagon-like peptide-1 receptor agonists, are among the most effective medications available for weight loss.
They work by mimicking the effects of a natural hormone called GLP-1 in your body. This hormone helps regulate your appetite, slows down digestion, and promotes a feeling of fullness after eating. By stimulating GLP-1 receptors, these medications can help you feel more satisfied with smaller portions of food, leading to reduced calorie intake and gradual weight loss over time.
They are a main ingredient in injectable pens like Mounjaro® and Wegovy®, which are often prescribed alongside a balanced diet and regular exercise to achieve the most effective results in managing weight.
Yes, the injectable treatments (Mounjaro® KwikPen and Wegovy®), and Alli® are all licensed for weight loss in the UK.

“Definitely be ordering again”
My order came within 24 hours. Very happy with the service I received from this company. I will definitely be ordering again.
“Being confidential is important to me”
MedExpress was a good experience. I needed help with my weight and it was nice to get advice for the different treatment I could use. Also the fact that it was confidential is very important. Having a lot of weight can be uncomfortable to talk front of stranger or even front of family. This is why I would recommend it.
“Very quick delivery”
Very easy to follow and order products as required, and very quick delivery.
“Fantastic service from start to finish”
Using Wegovy for about 4 weeks now and not only the product itself is fantastic, but the service from MedExpress is fantastic from consultation, ordering, delivery, re-ordering reminders. Also great to see the links between MedExpress and my own GP here in Northern Ireland. Sometimes in Norther Ireland we are treated like we are not part of the UK for deliveries etc. so was great to see that there were no hic-ups in the ordering of this product. Would highly recommend MedExpress.
“100% recommend this company”
If you are looking to order weight loss products this is the company to use. The process to order is easy, the website user friendly and the price so much better than a lot of other places. I have ordered from a London company previous to using MedExpress and literally only got sent the pen, no needles or instructions and postage was 3 x more expensive. MedExpress included tracked postage, needles, sharps box and 3 leaflets about using the product - so I 100% recommend this company - absolutely fantastic service. Thank you.
