What are weight loss injections?
Weight loss injections are prescription medicines from a group known as GLP-1 receptor agonists. They work in a similar way to a hormone your body releases after eating, helping you feel fuller sooner and for longer, and reducing food cravings. Used alongside changes to diet and physical activity, they can support steady, sustainable weight loss for people living with obesity or who are overweight with a related health condition. They are not a quick fix or a substitute for healthy habits — they are a clinical tool that works best as part of a supported programme. Treatment is prescription-only in the UK and must be supplied after a consultation with a registered prescriber, who checks that it is safe and suitable for you before any medicine is dispensed.
How our online weight management programme works
Our service is built to be simple, private and properly clinical. There are four steps:
- Check your eligibility. Use our free BMI and eligibility checker to see whether you may meet the usual threshold.
- Complete your consultation. Answer a confidential health questionnaire about your weight, medical history and current medicines. It takes only a few minutes.
- Prescriber review. A GPhC-registered prescriber reviews your information and decides whether treatment is appropriate. They may contact you for more detail.
- Treatment and support. If approved, your medicine is dispatched in discreet packaging for next-day delivery, with clear instructions and ongoing dose support.
Am I eligible for treatment?
Prescription weight management is generally suitable for adults with a BMI of 30 or above, or a BMI of 27 or above where there is a weight-related health condition such as type 2 diabetes, high blood pressure, raised cholesterol or obstructive sleep apnoea. This mirrors the approach used across UK weight management services. Our eligibility checker gives you an instant estimate, but the final decision always rests with the prescriber after reviewing your full health information.
Treatment is not suitable for everyone. It is not prescribed during pregnancy or breastfeeding, and certain medical histories mean a different approach is safer. Being honest in your consultation helps us keep you safe.

Is it safe? Side effects to know about
When prescribed and monitored properly, GLP-1 weight management medicines have a well-understood safety profile. The most common side effects are digestive — nausea, constipation, diarrhoea or feeling full quickly — and these usually ease as your body adjusts and the dose is increased gradually. Less common but more serious effects are rare; your prescriber will explain the warning signs to look out for and what to do. Because we monitor your progress, we can adjust your dose or pause treatment if you experience problems. This ongoing oversight is exactly why buying these medicines from unregulated online sellers is risky: the MHRA has repeatedly warned that medicines bought outside the regulated pharmacy system may be fake, incorrectly dosed or unsafe.
