Trial figures are averages from separate placebo-controlled trials with different people, lengths and doses. They do not rank one medicine above another. Your prescriber will advise on the right choice for you.
What a month costs
Both weekly injections come as a pen holding four doses. Four weeks of treatment equals one pen, so the price per pen is your monthly cost. Prices on iGovy include delivery.
The price rises at each dose step. Your first month is often discounted. From the second month you pay the pharmacy's standard price, shown on the Wegovy price list UK.
What the first year involves
Wegovy starts at 0.25mg and moves up every four weeks: 0.5mg, 1mg, 1.7mg, then 2.4mg. Most people reach the 2.4mg maintenance dose after 16 weeks. The Wegovy leaflet also allows 7.2mg for people who have been on 2.4mg for at least four weeks, if the prescriber agrees.
A year holds 13 four-week months. In a typical first year you buy four starter pens, one at each lower dose, then nine pens at your maintenance dose. The maintenance price therefore sets most of the yearly cost. Compare pharmacies on the maintenance price, not only the first month.
Private cost against the NHS
Private
You pay the full pen price each month. You start within days, after an online consultation. The pharmacy sets its own BMI rules for starting and staying on treatment.
NHS in England
You pay the standard prescription charge per item, or nothing if exempt. Access follows NICE guidance: TA875 for Wegovy and TA1026 for Mounjaro. Wegovy on the NHS runs through specialist weight services for up to two years.
Scotland, Wales, Northern Ireland
Prescriptions are free. Access still depends on local weight services and waiting lists.
Extra costs to watch
- Consultation fees. Most online pharmacies include the consultation. A few charge a separate fee.
- Delivery. Pens need cold delivery. iGovy prices already include delivery.
- Needles and sharps bins. Wegovy pens come with needles. Some pharmacies charge for a sharps bin.
- Price rises after month one. The largest hidden cost. Check the standard price before you order.
- Gaps in treatment. Stopping for a few weeks sometimes means restarting at a lower dose, which adds months to the climb.

How iGovy checks prices
iGovy is run by Medstack Ltd, an independent UK company (Companies House 16439872). We do not sell, prescribe or dispense medicines. Prices are checked against each pharmacy's own checkout several times a day and shown as the delivered total for one month. Every pharmacy's certificates are checked by hand before listing. Some links earn a referral fee. Fees never change the order of the price table.
Weight loss injection cost questions
How much are weight loss injections per month in the UK?
One pen covers four weeks, so the pen price is the monthly cost. Wegovy's first dose is the cheapest starting point at most pharmacies, and the price rises with each dose. iGovy shows the live delivered price for every Wegovy dose.
How much do weight loss injections cost per year?
A first year holds 13 four-week months: four starter pens at the lower doses and nine at your maintenance dose. The maintenance dose price sets most of the yearly total, so compare pharmacies on the maintenance price.
Why do weight loss injections get more expensive?
Higher doses cost more per pen, and most first-order discounts end after month one. Both push the monthly cost up during the first four months.
How much is a weight loss injection on the NHS?
In England you pay the standard prescription charge per item unless you are exempt. Prescriptions are free in Scotland, Wales and Northern Ireland. NHS access follows NICE criteria and is limited.
Is Mounjaro more expensive than Wegovy?
At the starting dose, yes, at most pharmacies. At higher doses the gap is smaller. Monj shows live Mounjaro prices and iGovy shows live Wegovy prices.
Are there hidden fees with weight loss injections?
Watch for separate consultation fees, delivery charges and sharps bins. iGovy prices include delivery and fees added at checkout.
