Wegovy is made as a biologic medicine, meaning it uses recombinant technology to produce semaglutide, a protein-based drug. Mysimba and Orlistat, by contrast, are small-molecule tablets made by chemical synthesis. These differences influence regulation and supply but not day-to-day use for patients. What makes Wegovy a biologic Wegovy (semaglutide) belongs to a group of medicines known as biologics. These are typically large, complex molecules produced in living cells using r

Both contain semaglutide and improve blood sugar by enhancing insulin release and reducing glucagon. Ozempic is specifically licensed for diabetes at lower doses, while Wegovy provides the same benefits at higher doses alongside more pronounced weight reduction. How semaglutide works on blood sugar Semaglutide, the active ingredient in both Wegovy and Ozempic, belongs to the GLP-1 receptor agonist family. It lowers blood sugar by stimulating insulin release when glucose level

Yes — trials show Wegovy users lose more weight earlier than with Saxenda, thanks to its stronger appetite effect and weekly dosing. That said, both require steady use over months for results to build. The two medicines at a glance Wegovy and Saxenda belong to the same family of medicines, GLP-1 receptor agonists. They help people feel fuller sooner, reduce appetite, and support healthier eating. The difference lies in the active ingredient and how they are dosed: Wegovy cont

In many cases, Wegovy can be used as the main weight loss medicine, especially when diet and exercise alone haven’t worked. However, switching or replacing other drugs should always be guided by a clinician, as some combinations may still be appropriate depending on health needs. Wegovy as a first-choice option Since its approval by NICE in 2023, Wegovy (semaglutide 2.4 mg weekly) has become the leading option for medical weight management in the UK. Clinical evidence from th

Wegovy mimics the hormone GLP-1, acting on the brain to reduce appetite and slow digestion. Contrave (naltrexone/bupropion) affects brain reward and craving pathways, which can reduce emotional eating but doesn’t directly target satiety hormones. How Wegovy works Wegovy (semaglutide 2.4 mg weekly) is a GLP-1 receptor agonist. It mimics a natural gut hormone called GLP-1, which signals to the brain that you are full, slows down stomach emptying, and enhances insulin release wh

Both Wegovy (semaglutide 2.4 mg) and Trulicity (dulaglutide) improve blood sugar, but semaglutide generally produces greater reductions in HbA1c and body weight. NICE recommends semaglutide more widely for people needing weight-focused management. Two GLP-1 medicines, one key difference Wegovy and Trulicity both belong to the GLP-1 receptor agonist family of medicines. They mimic the hormone GLP-1, which reduces appetite, slows digestion, and stimulates insulin release when b

Nausea? Hair loss? Headaches Acid reflux? Sulphur burps? These can be some of the most common side effects when using weight loss medications such as Mounjaro and Wegovy. We can help.

The most common side effects with Wegovy are gastrointestinal, such as nausea and diarrhoea, and these often lessen over time. Other medicines have different risks: Orlistat can cause oily stools, Mysimba may raise blood pressure, and phentermine (not used in the UK) carries cardiovascular risks. Understanding risk in context All weight-loss medicines come with benefits and risks. Doctors weigh these carefully before prescribing, taking into account a person’s health conditio

The SELECT trial showed semaglutide 2.4 mg (Wegovy) reduced the risk of major heart problems in people with overweight or obesity and cardiovascular disease. Orlistat, while useful for modest weight loss, has not shown the same scale of cardiovascular benefits in large outcome studies. Two very different medicines Wegovy and Orlistat are both prescribed for weight management, but they work in completely different ways. Wegovy (semaglutide) is a GLP-1 receptor agonist that red

In the UK, coverage depends on NHS commissioning rather than insurance, and NICE now recommends Wegovy within specialist services. Saxenda has more limited NHS use. In private healthcare or in other countries, coverage varies by insurer, but newer guidance tends to prioritise Wegovy because of its stronger results. The UK context: NHS commissioning, not insurance Unlike in the United States, where health insurance policies determine which drugs are covered, the UK relies on t

Trials such as STEP-1 and SELECT showed Wegovy not only reduced weight but also improved blood pressure, cholesterol, and markers of heart health. Other medicines, like Saxenda, also improve some metabolic measures but to a smaller extent, and drugs like Orlistat mainly affect fat absorption rather than broad cardiometabolic outcomes. Why metabolic health matters Weight management is not just about the number on the scales. Many of the health risks linked to excess weight — i

In STEP trials, people using Wegovy started to see weight changes within the first 4–8 weeks, with maximum effects building over about a year. Ozempic, studied mainly for diabetes, also showed early improvements in blood sugar and weight within weeks, but average weight loss was smaller because of its lower doses. Early signs of progress One of the most common questions people ask is how soon results can be seen. In clinical trials of Wegovy (semaglutide 2.4 mg), participants

After first use, a pen can usually be kept below 30 °C (cap on, away from light) for up to 6 weeks — then it must be discarded, even if medicine remains. Unopened pens belong in the fridge; if they have been kept at room temperature on purpose, many packs allow a limited period out of the fridge — your leaflet sets the exact limit. Never freeze, never overheat (hot cars, radiators, direct sun), and never store with a needle attached. Why storage rules matter Wegovy (semagluti
