How to Get Weight Loss Injections in the UK
A safe, step-by-step guide to obtaining prescription weight loss medication like Mounjaro and Wegovy through regulated UK providers.
Getting weight loss injections in the UK is a strictly regulated process. Whether you choose the NHS route or a private prescription, these medications (such as Mounjaro, Wegovy, and Saxenda) are Prescription Only Medicines (POMs).
This means you cannot buy them "off the shelf". You must complete a medical consultation to ensure the treatment is safe for you. Here is exactly how the process works.
Check Your Eligibility
To be prescribed weight loss injections in the UK, you must meet specific medical criteria known as the "NICE guidelines". Generally, you must have:
Standard Criteria
A Body Mass Index (BMI) of 30kg/m² or higher (classified as obesity).
Alternative Criteria
A BMI of 27kg/m² to 30kg/m² (overweight) AND at least one weight-related health condition (e.g., high blood pressure, pre-diabetes, high cholesterol).
Choose Your Route: NHS vs Private
NHS Route
- Free of charge (prescription fee may apply).
- Comprehensive support via Tier 3 Weight Management Services.
- Long waiting lists (often 12-24 months).
- Stricter criteria and limited availability.
Private Prescription
- Fast access (usually within 24-48 hours).
- Convenient online consultation process.
- Discreet home delivery.
- Costs between £140 - £200 per month.
The Online Consultation Process
If you choose a private online pharmacy, the process is simple but thorough. Here is what to expect:
Medical Questionnaire
You will answer questions about your current weight, medical history, and any other medications you are taking. Be honest—this ensures your safety.
Prescriber Review
A UK-registered clinician (doctor or pharmacist) reviews your answers. If approved, they issue an electronic private prescription.
Discreet Delivery
Your medication is dispatched in unmarked packaging. Mounjaro and Wegovy pens require "cold chain" delivery (refrigerated packaging) to stay effective.
Safety Checklist: Avoiding Scams
Buying medication online can be risky if you don't know what to look for. Always check these 3 things:
GPhC Registration
The pharmacy must display the General Pharmaceutical Council (GPhC) logo and registration number.
Registered Address
They must have a physical UK address listed on their website.
Prescription Requirement
NEVER buy from a site that doesn't ask for a consultation or prescription. It is illegal and dangerous.
