Detailed Answer

The cost of weight loss medication in the UK varies depending on the specific medication, the dose you are on, and the provider you choose. All prices listed below are for private prescriptions and typically include the cost of an online consultation with a registered prescriber.

Mounjaro (tirzepatide): starting prices for the initial 2.5mg dose are typically £149–179/month. As you progress through the dose escalation schedule, costs increase. Higher doses (10mg–15mg) typically cost £250–350/month depending on the provider.

Wegovy (semaglutide): starting prices for the 0.25mg dose are approximately £155–185/month. The maintenance dose of 2.4mg typically costs £260–320/month. Wegovy supply has historically been constrained by global manufacturing issues.

Saxenda (liraglutide): prices start from approximately £155/month for the 0.6mg dose. As a daily injection (rather than weekly), Saxenda requires more pens per month at higher doses, which increases cost. Full maintenance dose (3.0mg) typically costs £180–250/month.

Some providers offer bundle discounts for multi-month supplies or subscription plans with reduced pricing. Always check whether the quoted price includes the consultation fee, and verify the provider is GPhC-registered before purchasing.

On the NHS, weight loss medication is available through specialist weight management services at no cost to the patient (beyond standard prescription charges where applicable). However, NHS access is currently limited and varies by region.
