Why the Most Effective Weight Loss Treatment Isn’t a Pill at All
At Junction Pharmacy in Brixton, one of the most common questions we hear is: What is the strongest weight loss prescription pill? It’s a completely valid question—after all, most of us are used to taking pills when we need help managing our health. But when it comes to long-term, sustainable weight loss, the most effective solution isn’t actually a pill at all.
In recent years, weekly weight loss injections like Wegovy and Mounjaro have emerged as powerful, medically-proven treatments that outperform traditional tablets in both results and patient satisfaction. And no, they’re not as intimidating as they sound.
In this blog, we’ll explore why it’s time to rethink weight loss medication—and why injections, not pills, are now considered the gold standard in medical weight management.
The Problem With Weight Loss Pills
For years, prescription pills like Orlistat (Xenical) and phentermine have been used to help people shed excess weight. While these tablets can work for some, they often come with limited success, unwanted side effects, and inconsistent long-term results.
Orlistat, for example, works by preventing fat absorption in the gut. This might sound useful, but it often leads to uncomfortable digestive issues such as diarrhoea and bloating.
Phentermine, a stimulant-based appetite suppressant, is not widely prescribed in the UK due to safety concerns and its potential for dependency.
Other weight loss pills available under NHS or private prescribing schemes often rely on modifying neurotransmitters or blocking absorption, with modest weight loss outcomes at best.
So, while people continue asking what is the strongest weight loss prescription pill, the truth is that stronger doesn’t necessarily mean better—especially when the body adapts or side effects outweigh the benefits.
The Rise of Weight Loss Injections
Enter Wegovy (semaglutide) and Mounjaro (tirzepatide): weekly injectable medications that are changing the landscape of obesity treatment.
These treatments don’t work like traditional pills. Instead of simply suppressing appetite or blocking fat, they mimic the body’s natural hormones involved in hunger and digestion. Both medications target GLP-1, a hormone that helps regulate appetite and blood sugar. Mounjaro also targets GIP, giving it a second mechanism that may enhance its effect for some people.
The result? Reduced hunger, longer feelings of fullness, fewer cravings, and more consistent weight loss—without the rollercoaster crash diets or willpower battles. Of course, pairing your weight loss journey with physical activity and healthy eating habits can make a real difference and help you achieve lasting results.
Clinical Results Speak Volumes
Numerous trials have shown that Wegovy and Mounjaro outperform all existing oral weight loss medications, both in terms of effectiveness and sustainability.
Wegovy users lost an average of 15% of their body weight over 68 weeks in clinical trials, when combined with a healthy diet and regular activity.
Mounjaro users experienced even more dramatic results—some losing up to 20% or more of their body weight in comparable timeframes.
Compare that to the modest 3–5% weight loss usually associated with prescription pills, and it becomes clear why so many people are turning to injectable support.
But Aren’t Injections Harder to Use?
We understand that the idea of an injection can be off-putting at first—but rest assured, both Wegovy and Mounjaro come in simple, pen-style injectors designed for easy at-home use. The injection is done just once a week, and we’ll show you exactly how to use it during your consultation.
Most patients find it quick, painless, and much easier than taking daily pills, especially once they see the results start to appear.
