New weight loss drugs for 2022

Overview of newer UK weight loss medicines — GLP-1 injectables, oral options, and emerging treatments patients and prescribers are watching.

Since it's approval, it has become the first weight loss drug to be approved for treatment of chronic weight management since 2014. The FDA will be using higher form of Wegovy's diabetes medication, Semaglutide as a form of weight-loss medication in patients with obesity.

Wegovy from Novo Nordisk

UPDATE : September 2023, Wegovy has now been released into the UK market by Novo Nordisk.

Tirzepatide from Eli Lilly

Tirzepatide has recently hit the headlines in the UK due to the Food and Drug Administration’s (FDA) approval of the drug to treat type 2 diabetes in the US. Whilst Tirzepatide is only available for type 2 diabetes and only sanctioned for use in the United States, this does show some promise for use in the UK in the future. As of June 2022 we do not know what the plans are for Tirzepatide in the UK market and it is not licensed with the MHRA.

Tirzepatide is available as a weekly injection under the brand name of Mounjaro in the US for the treatment of type 2 diabetes . Mounjaro(Tirzepatide) comes in three different doses which are 5mg, 10mg and 15mg, with a patient’s dose adjusted as tolerated to meet blood sugar goals.

The clinical trials of Eli Lilly’s Tirzepatide have exceeded the results achieved in trials of Novo Nordisk’s Wegovy but caution should be taken when drawing comparisons between trials of different drugs amongst different cohorts of trials patients. It is important to note that all patients respond differently to different treatments and that results will be different between patients.

Unlicensed treatments

At PrivateDoc we often receive enquires about the use of unlicensed products for weight loss. An unlicensed product is one that is used outside of the terms of the UK license for the product or the product has no license for use in the UK.

As a leading online clinic PrivateDoc will only prescribe licensed medicines in accordance with the terms of their licence in the UK.

PrivateDoc may provide a license product to support weight loss on the basis of an assessment of an individual patient and the prescribing doctor decides it its appropriate to supply the medicine to meet the specific needs of the patient. In this instance an off license prescription will be made, but only with the consent of the patient and their understanding that the prescription is off license.

At PrivateDoc our key concern is patient safety and the ethical supply of medicines where appropriate and effective, supported by a treatment plan.

Our advice at PrivateDoc

As of June 2022 the UK has a number of licensed treatments for weight loss that are available to patients, on prescription, under the supervision of experienced GPs in managing obesity and weight loss.

At PrivateDoc we prescribe the complete range of licensed medicines where appropriate, with patients able to choose between Wegovy, Saxenda, Mysimba and Orlistat.

Whilst it might be tempting to wait for the new medicines coming to the UK market; the best time to lose weight and realise the health benefits is now. It is important not to rely on the results of others as indication of success for you and you should commit to weight loss medicine use only when diet and exercise has failed to deliver results on there own.
