Question 1

How much do weight-loss injections cost in the UK?

Accepted Answer

Private weight-loss medication in the UK typically costs around £100–£350 a month depending on the medicine and your dose. WeightMedsCompare lists current monthly prices side by side, along with what each price includes.

Question 2

Who is eligible for weight-loss medication?

Accepted Answer

Private prescribing usually follows the licensed basis: a BMI of 30 or above, or 27 or above with a weight-related condition. Lower thresholds apply for some ethnic groups. NHS criteria are generally higher. A registered prescriber makes the final decision.

Question 3

What is the difference between Mounjaro, Wegovy and Saxenda?

Accepted Answer

Mounjaro (tirzepatide) and Wegovy (semaglutide) are weekly injections; Saxenda (liraglutide) is daily. They differ in how they act, their side-effect profiles and their price. Individual results vary and suitability is decided by a prescriber.

Question 4

Is WeightMedsCompare independent?

Accepted Answer

Yes. Rankings are not paid. Some outbound links are affiliate links and some providers can pay for a clearly-labelled Sponsored placement, but this never changes the organic order. See our funding and disclosure pages for details.
