With recent price increases for Mounjaro, now may be a good moment to review your treatment options. If you’re happy with your current medication and the new price works for you, there’s no need to change — Mounjaro remains a highly effective choice. But if you’d like to explore alternatives, our guide explains when switching to Wegovy could make sense, how the process works, and what to expect.
The Benefits of Losing Weight
Weight loss is more than a number on a scale, it’s about improving your overall health. Losing weight reduces the risk of conditions like heart disease, type 2 diabetes, and certain cancers. It also relieves stress on your joints, enhances sleep quality, and boosts energy levels. At Happy Pharmacy, we’re here to help you achieve these life-changing benefits.
Most types of weight loss medication work best when combined with exercise, sleep improvements, and better nutrition. Plus, treatments that help you to lose weight often encourage healthier eating habits, allowing you to eat less and lose weight naturally.
Wegovy vs Mounjaro – Dosage & Weight Loss Timeline
Choosing the right, effective weight loss treatment depends on your goals, medical history, and starting body weight. Both Wegovy and Mounjaro deliver weekly injections that result in noticeable progress, typically from body weight after 12 weeks onward. For some, weight loss can be achieved in even less time when combined with diet and exercise.
Your rate of weight loss will vary based on adherence to your weight loss plan, dietary habits, and physical activity levels.
At Happy Pharmacy, we provide both Wegovy and Mounjaro, two powerful, once-weekly injectable medications for weight loss. Whether you're just starting your journey or comparing treatment options, view our dosage timeline for what you can expect from each.

How do weight loss injections work?
Weight-loss injections such as Wegovy (semaglutide) and Mounjaro (tirzepatide) work by mimicking natural hormones that help control appetite, digestion and blood sugar levels. These medications send signals to your brain that make you feel fuller for longer, reduce cravings, and slow how quickly food leaves the stomach — making it easier to maintain a calorie deficit and lose weight sustainably.
Both medicines are injected once a week using a pre-filled pen, and doses are increased gradually over several weeks to reduce side effects.
How Mounjaro Works (Tirzepatide)
Mounjaro activates two key hormone pathways:
- GLP-1, which reduces appetite and slows digestion
- GIP, which improves insulin sensitivity and helps stabilise blood sugar
Acting on both receptors allows Mounjaro to control hunger more strongly than single-pathway treatments. In clinical trials, patients taking Mounjaro alongside healthy-lifestyle changes have achieved up to 22% weight loss over 18 months. It can be particularly helpful for people with insulin resistance or pre-diabetes.
How Wegovy Works (Semaglutide)
Wegovy targets the GLP-1 receptor, a hormone released naturally after eating. By enhancing this signal, Wegovy helps you feel full sooner, reduces food cravings and slows gastric emptying, which supports long-term calorie control. Clinical trials show that adults using Wegovy with a balanced diet and increased activity can expect around 15–17% weight loss on average.
Why These Treatments Are Effective
GLP-1 and GIP–based treatments support weight management by:
- lowering appetite
- reducing cravings and emotional eating
- slowing digestion to prolong fullness
- stabilising blood sugar levels
- helping you stick to a reduced-calorie diet more comfortably
During your online consultation, our GPhC-registered pharmacists assess your medical history, BMI, and lifestyle to ensure any treatment prescribed is both safe and suitable for your health needs.
How do weight loss tablets work?
Prescription weight-loss tablets such as Orlistat (branded as Alli) work differently from injections. Instead of affecting appetite, they block the absorption of up to 30% of dietary fat, meaning fewer calories are absorbed by the body.
When used alongside a lower-fat, reduced-calorie diet, Orlistat can support a 5 to 10% reduction in body weight within a few months. It is often prescribed for adults with a BMI of 28 or higher, especially when lifestyle changes alone have not produced results.
All medications supplied by Happy Pharmacy are dispensed by UK based GPhC licensed pharmacists and authorised for use by the Medicines and Healthcare products Regulatory Agency (MHRA). During your online consultation, our pharmacists assess each case individually to ensure every treatment is safe, effective, and appropriate for your health profile.
FAQs
Which treatment is right for me?
When deciding between injections and tablets, consider how they’re taken, their effectiveness, cost, and side effects:
- Injections: Often provide more significant weight loss (15-20%) but are higher in cost and require needle use.
- Tablets/Capsules: A simpler, less invasive option, generally resulting in around 5% weight loss.
Both types are effective when used as part of a broader lifestyle plan that includes diet and exercise.
How to sustain weight loss
While medications can enhance weight loss, lifestyle changes play a critical role. Here are some proven strategies:
- Calorie Tracking: Keep a log of everything you eat to stay aware of your intake.
- Smaller Portions: Start with a modest serving and focus on low-calorie, nutrient-rich foods.
- Stay Hydrated: Drinking water before meals can help reduce appetite.
- Prioritize Sleep: Insufficient sleep affects hunger hormones, making weight management harder.
- Stay Active: Regular exercise, whether walking, cycling, or strength training, supports long-term weight loss.

What are the side effects of weight loss treatment?
Weight loss injections like Mounjaro and Wegovy can cause common side effects such as nausea, constipation, diarrhoea, or injection-site reactions—particularly during dose escalation. These are typically mild and manageable.
Tablets may cause digestive issues if dietary fat is not controlled. Our online pharmacist provides clear guidance to reduce discomfort, and such effects often diminish over time. Safety remains central, with regular check-ins and weight loss support offered throughout your regimen.
