Superdrug: No Stock Available

Superdrug Online Doctor has taken the bluntest approach, stating outright that it is out of stock due to the national shortage. Its site directs patients to check back frequently or consider switching to Wegovy in the meantime.

The Bigger Picture

Not every provider is handling the price rise in the same way. Some, like Numan and MedExpress, are temporarily freezing prices. Others, like Asda, are adjusting gradually and keeping patients updated. And some, like Superdrug, are facing outright shortages.

For patients, this means:

Short-term relief is possible if your provider is still selling old stock at old prices.
Expect higher prices soon, no matter what. Once supplies are replenished, the hike will hit.
Communication is patchy; each provider is handling it differently, so you’ll need to check directly with yours.

One thing is certain: the old Mounjaro prices are running on borrowed time. But for now, at least, some UK prescribers are giving patients a brief reprieve.

Everyone’s situation is different, so always confirm with your healthcare provider before making any treatment changes.

MedExpress: Prices Held “As Long As Possible”

MedExpress, known for its lower-cost prescriptions, is also freezing prices for now. But it has published the future prices it expects to charge once old stock runs out:

2.5 mg → £149.99 (future: £179.99)
7.5 mg → £169.99 (future: £249.99)
15 mg → £199.99 (future: £309.99)

The company makes it clear that this is temporary: “We are holding current prices for as long as possible, while stocks last.”

Asda Online Doctor: “We’ll Keep You Updated”

Asda Online Doctor is taking a slightly different tack. On its site, it notes that “the cost of Mounjaro has recently increased”, but stresses that patients will always see the price at checkout before ordering.

Asda’s update strikes a softer note:

“We know a price increase can be worrying… Our priority is to keep you informed and help you continue your treatment safely.”

The provider also acknowledges supply pressures, with order processing times currently at 14 days and phone lines temporarily unavailable.

Eli Lilly’s 170% wholesale price increase for Mounjaro kicks in from 1 September, pushing the top dose from around £122 to £330 per month (Reuters, 14 Aug 2025). For patients paying privately, that’s a huge jump.

But here’s the surprising twist: not every UK prescriber is passing on the hike immediately. Several providers are freezing prices, at least for now, to give patients breathing room.

At Least One Prescriber Has Frozen Prices... For Now

In an email to patients, Numan reassured customers that orders placed before 7 September would still be charged at the old rate. After that, “a smaller adjustment” to prices may be necessary.

Numan wrote:

“If you request [an order] on or before Monday 7th September, your order will be guaranteed at current prices… While a smaller adjustment to our prices may be necessary, we’re fully committed to supporting the progress you’ve already made.”

Numan’s website is also promoting a £95/month offer for new patients, with £84 off the first treatment. It’s a rare sight, a price drop, even as the wholesale cost soars.
