Each prescription weight loss medication works in a slightly different way, as they contain different active ingredients. Wegovy, Mounjaro, Saxenda and Mysimba all work on the brain and other organs, to reduce appetite levels and cravings, making it easier to eat less and lose weight.

Orlistat, alli, and Xenical work by changing how your body digests fat. alli is actually an over-the-counter weight loss pill, but a doctor or pharmacist still needs to check your BMI and medical history to make sure it’s suitable.

We have a range of weight loss treatments available that can help you lose weight, including tablets and injections. These need to be prescribed for you and can be used if you are obese, or if you are overweight and have other medical problems that are affected by weight, such as diabetes or high blood pressure.
