Cost is one of the most frequently asked questions about weight loss injections at Newdays Pharmacy in Berkshire. Understanding what you are paying for, how prices break down by dose and treatment stage, and how to compare costs across different providers without compromising clinical safety, helps patients make informed decisions about accessing weight management treatment.
How Weight Loss Injection Pricing Works
Weight loss injections are sold as pre-filled injection pens that contain four weekly doses per pen, providing one month of treatment. Prices vary depending on the dose: the starting dose, used for the first four weeks, is cheaper than the higher maintenance doses used later in treatment. This means costs increase as the dose is titrated upward. The full cost of a treatment course should be considered from initiation through to maintenance dose, not just the starting dose advertised by some providers.

Typical 2026 UK Costs for Wegovy (Semaglutide 2.4mg)
Wegovy is available in five dose strengths as the dose is escalated from 0.25 mg to the 2.4 mg maintenance dose over approximately twenty weeks. Starting dose pens are lower cost, with the maintenance dose pen representing the highest ongoing monthly cost. Monthly costs at the 2.4 mg maintenance dose have ranged from approximately £175 to £295 in the UK private market in 2026. Supply constraints have historically driven price variation.
What Else Should I Budget For?
- Initial consultation fee: a private pharmacist led consultation is typically charged separately. At Newdays Pharmacy our consultation fee will be confirmed when you book
- Follow up monitoring: ongoing clinical oversight, follow up appointments, and monitoring are included in a properly managed programme and represent additional value beyond the medication cost alone
- Blood tests: a baseline blood glucose, HbA1c, blood pressure, and weight measurement are taken as part of the clinical assessment
Why Cheap Online Providers Are a Clinical Risk
Some online providers advertise very low cost weight loss injections, often by using minimal or automated clinical assessments. At best, this means inadequate clinical oversight. At worst, it means counterfeit or unlicensed products. GPhC investigations have found examples of substandard products being supplied through unregistered online pharmacies. Always verify that your provider is a GPhC registered pharmacy with a named superintendent pharmacist.
