General Advice

Yes. You can change to a new weekly day as long as at least 3 full days have passed since your last injection. Once you switch, keep using the new day each week. If you’re unsure about the timing, ask your clinic to help you plan the change. Why flexibility exists Wegovy is designed as a once-weekly injection, and the dosing rules were created with real life in mind. Few people manage a routine that never changes. Work patterns, holidays, travel, or family events can all inte

Any time of day works — morning or evening — because the weekly dose is designed to be flexible. Pick a time you can stick to, keep it the same each week, and set a reminder so doses aren’t missed. If your routine changes (shift work, travel), you can move the time as long as your weekly schedule stays consistent. A flexible schedule Wegovy is designed as a once-weekly injection, and its long half-life means the exact time of day does not affect how well it works. Whether you

In major STEP trials, Wegovy led to about 15% weight loss over 68 weeks. Contrave (called Mysimba in the UK) generally achieves around 6–9% across pivotal studies. This means semaglutide tends to provide greater weight reduction than naltrexone/bupropion combinations. Two very different medicines Although both Wegovy and Contrave are used for weight management, they belong to very different drug families and work in different ways. Wegovy contains semaglutide, a GLP-1 recepto

Wegovy contains semaglutide at a higher dose and is licensed for weight management, while Trulicity (dulaglutide) is prescribed for type 2 diabetes. Weight changes with dulaglutide are usually modest compared with the significant reductions seen in trials of semaglutide for obesity. Different active ingredients and purposes The first key difference is that Wegovy and Trulicity contain different GLP-1 receptor agonists. Wegovy delivers semaglutide at doses up to 2.4 mg weekly,

Standard UK instructions start at 0.25 mg once weekly and step up gradually to improve comfort and reduce tummy side effects. Starting at 0.5 mg is not the routine plan and tends to increase nausea for first-time GLP-1 users. If you’ve previously tolerated a GLP-1, your prescriber will still weigh the pros and cons before deviating from the usual start. Why titration matters Wegovy contains semaglutide, a GLP-1 receptor agonist that acts on appetite control centres in the bra

You can change your weekly injection day if needed, as long as there are at least 3 days (72 hours) between two doses. After switching, keep to the new weekly day going forward. For missed doses, the rule is different: if you are within 5 days, take it as soon as you remember; if it has been more than 5 days, skip it and take the next dose on your usual day. Why flexibility is built in Wegovy is prescribed as a once-weekly injection. The idea is to give people a medicine that

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

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.

Yes, NICE guidance states that Wegovy can be offered to adults with a BMI over 35 and at least one weight-related condition, or sometimes with a BMI over 30 if criteria are met. Other drugs, like Saxenda or Mysimba, have similar but slightly different BMI thresholds, while diabetes drugs like Trulicity are prescribed on blood sugar criteria instead. Wegovy and its eligibility rules In the UK, NICE sets out clear criteria for who can be prescribed Wegovy. It is recommended for

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

In major STEP trials, Wegovy led to about 15% weight loss over 68 weeks. Contrave (called Mysimba in the UK) generally achieves around 6–9% across pivotal studies. This means semaglutide tends to provide greater weight reduction than naltrexone/bupropion combinations. Two very different approaches Although both Wegovy and Contrave are prescribed for weight management, they work in completely different ways.

Yes, Wegovy and metformin are often used together in people with type 2 diabetes, and no special dose adjustment is typically required. They work differently: Wegovy (a GLP-1 receptor agonist) reduces appetite, slows stomach emptying, and boosts insulin release, while metformin mainly reduces glucose production in the liver and improves insulin sensitivity. Why these medicines are combined Doctors frequently prescribe Wegovy (semaglutide) alongside metformin, particularly in
