Weight loss injections are taken once a week, with each pen providing four weeks of treatment. They work by helping to reduce appetite and increase feelings of fullness, making it easier to manage portion sizes and calorie intake. Treatment starts at a lower dose and is gradually increased over time to help your body adjust.
No treatments are currently available to order. You can still explore the options below or contact our pharmacy team for help.

These trials studied adults without type 2 diabetes, with diet and activity support. Different studies and analyses are not a head-to-head comparison. Results vary and may be lower or none. A prescriber—not this chart—decides whether a medicine or dose is suitable for you.

Mounjaro is a newer injectable medication used in weight management and metabolic health. It works on multiple hormonal pathways involved in appetite regulation and blood sugar control. As awareness grows, many patients are researching Mounjaro weight loss injections as part of their weight management journey.
Semaglutide is a prescription medication used in weight management and metabolic health. It belongs to a class of medications known as GLP-1 receptor agonists, which help regulate appetite and food intake. Semaglutide is commonly associated with weight loss treatments that are administered via weekly injections.
Wegovy is a prescription weight loss injection that contains the active ingredient semaglutide. It has been developed specifically for chronic weight management in eligible patients. Wegovy is taken as a once-weekly injection and is designed to support sustainable weight loss when used correctly.
What Are GLP-1 Weight Loss Injections? GLP-1 weight loss injections are prescription medications designed to support weight management by helping regulate appetite and food intake. GLP-1 stands for glucagon-like peptide-1, a hormone that plays a key role in controlling hunger and blood sugar levels. These injections work by slowing digestion and increasing feelings of fullness, which can help reduce calorie consumption when used as part of a structured weight loss plan.
Medical weight loss has evolved significantly in recent years, with increasing attention on prescription treatments that support long-term weight management. One of the most talked-about developments is the rise of GLP-1 weight loss injections, which are now widely recognised as an effective option for eligible patients. At Platinum Online Pharmacy, we are preparing to support patients with access to modern weight loss solutions through a safe, regulated online pharmacy service.
Mounjaro and Wegovy are both once-weekly injections licensed in the UK for weight management. They work in related but different ways. Here is how a prescriber weighs them up.
Weight loss treatment no longer means an injection. Daily tablets were licensed in the UK in 2026. Here is how the two forms differ and what a prescriber considers.
Wegovy tablets put semaglutide, the active ingredient in the Wegovy injection, into a once-daily tablet. Here is what that changes and what it does not.
Most side effects of weight loss medication appear in the first weeks and after each dose increase. Here is why they happen, what helps, and the signs that need medical attention.
A questionnaire on its own is not enough to be prescribed a weight loss medicine in the UK. Here is what independent verification means and what it involves.

Speak to our pharmacy teamAdults aged 18 to 74 with a body mass index (BMI) of 30 or more. Also adults with a BMI of 27 or more and a weight-related condition, such as type 2 diabetes, high blood pressure or sleep apnoea. Your prescriber makes the final decision.
No. A prescription is not guaranteed. The prescriber decides on clinical grounds and may suggest an alternative or refer you to your GP. The assessment is free either way.
Your height, weight and BMI help the prescriber decide whether weight loss treatment is appropriate for you. Verifying these details gives them a more accurate picture of your suitability before any medicine is prescribed.
There are several ways we can verify your height and weight, depending on what’s most suitable for you. This may include a short video call, live video verification, a live selfie, or information from your GP or medical records.
That depends on your health, your other medicines and any treatment you have had before. Your prescriber will explain the options. The comparison on this page shows the main differences.
Often, yes. Tell us your current treatment and dose in the assessment. The prescriber can then continue it safely without restarting from the lowest dose.
