Foundayo UK — 7 proven facts.

Foundayo UK availability has made orforglipron the second licensed GLP-1 weight loss pill in Britain. Many people want to know what it costs, how to take it and how it compares with the Wegovy pill.

This guide covers Foundayo in full: doses, price, how to take it, trial results, side effects, NHS status and how it compares with Wegovy and Mounjaro.

Foundayo UK: what is it?

Foundayo is the brand name for orforglipron, a once-daily weight loss tablet made by Eli Lilly, the company behind Mounjaro. It works on the GLP-1 receptor, like Wegovy and Ozempic.

The MHRA approved it in August 2026, and Foundayo UK supply has been available in UK pharmacies from 24 August 2026. The UK was the first country in Europe to approve it.

Unlike the Wegovy pill, Foundayo is a small molecule rather than a peptide. That is why it can be taken at any time, with or without food.

1. Foundayo was approved by the MHRA in August 2026
2. It has been in UK pharmacies since 24 August 2026

4. Doses rise from 0.8mg to 17.2mg over at least five months
5. In ATTAIN-1, the highest dose gave 11.2% average weight loss over 72 weeks
6. Private prices start from around £129 a month at some providers
7. It is not yet available on the NHS

Foundayo UK doses

Foundayo UK packs come in six strengths. You start low and move up no more than once a month to help your body adjust.

Step	Daily dose	Minimum time
1	0.8mg	1 month
2	2.5mg	1 month
3	5.5mg	1 month
4	9mg	1 month
5	14.5mg	1 month
6	17.2mg	Maintenance

Maintenance can be anywhere from 5.5mg to 17.2mg, depending on your response and side effects. Your prescriber decides when, or whether, to move up.

How to take Foundayo

Foundayo UK patients find it one of the simplest GLP-1 treatments to take. That is its main difference from the Wegovy pill.

• Take one tablet once a day
• Take it at any time of day, ideally at a similar time each day
• Take it with or without food
• Swallow it whole with water; do not crush or chew it
• Never take more than one tablet in a day

The Wegovy pill, by contrast, must be taken on an empty stomach with a small sip of water and a 30-minute wait. Our how to take the Wegovy pill correctly guide explains those rules.

Cost and pricing

Foundayo UK supply is private, so each provider sets its own price. Prices usually rise with the dose.

Dose	Typical monthly price (example provider)
0.8mg, 2.5mg, 5.5mg	around £129
9mg	around £149
14.5mg, 17.2mg	around £179

These figures come from one UK provider and are a guide only. Some providers offer lower prices on longer plans, so compare the full cost, including consultations and delivery.

For comparison, see our Wegovy pill UK price and Mounjaro cost UK guides.

Trial results

The main trial behind Foundayo UK approval is ATTAIN-1. It followed more than 3,000 adults with obesity or overweight, without diabetes, for 72 weeks.

Result	Highest dose	Placebo
Average weight loss (all participants)	11.2%	2.1%
Average weight loss (stayed on treatment)	12.4%	—

Lower doses produced smaller but still meaningful weight loss. In ATTAIN-2, people with type 2 diabetes also lost weight and improved their blood sugar.

As with all GLP-1 medicines, results vary. Some people lose much more than average, others less.

Foundayo vs Wegovy pill and injections

Feature	Foundayo	Wegovy pill	Mounjaro
Medicine	Orforglipron	Semaglutide	Tirzepatide
Form	Daily tablet	Daily tablet	Weekly injection
Food rules	None	Empty stomach, 30-minute wait	None
Trial weight loss	11.2% (72 weeks)	13.6% (64 weeks)	Up to 20.9% (72 weeks)
Fridge	No	No	Yes, before first use

The trials differ in length and participants, so the figures are only a rough guide. Foundayo and the Wegovy pill have not been compared directly.

Foundayo UK patients who want the most weight loss may still do better on an injection. Our Wegovy pill vs pen and semaglutide vs tirzepatide guides compare the options.

Who can take it?

Foundayo UK licensing covers adults who meet the usual weight management criteria. It can also be used to improve blood sugar in type 2 diabetes.

• A BMI of 30 or above
• A BMI of 27 to 30 with at least one weight-related condition, such as high blood pressure or type 2 diabetes
• Adults with poorly controlled type 2 diabetes, for blood sugar control

Lilly says it is not intended for people who are not overweight or obese. A prescriber will check your health history before prescribing.

Side effects

Foundayo UK side effects are similar to other GLP-1 medicines. The most common are digestive and usually mild to moderate.

• Nausea
• Diarrhoea
• Vomiting
• Constipation
• Stomach discomfort and indigestion
• Reduced appetite

Side effects are most common in the days after a dose increase and usually ease as your body adjusts. Small meals, plenty of water and avoiding fatty food help.

NHS and NICE

Foundayo UK supply is currently private only. It is not yet available on the NHS.

NICE is assessing Foundayo, with final guidance expected in November 2026. If it is recommended, NHS prescribing could begin during 2027, possibly with strict eligibility criteria at first.

Until then, the only way to get Foundayo is through a private prescription from a regulated UK provider.

Who it may suit best

• People who dislike needles
• People with busy or irregular mornings who struggle with the Wegovy pill rules
• People who take other morning medicines
• Frequent travellers who want a fridge-free option
• People who want a gentler, gradual start

It may suit less well those who need the largest possible weight loss. Injections such as Mounjaro produced bigger average results in trials.

Switching from other medicines

Some people ask about Foundayo UK switching from Wegovy, Mounjaro or the Wegovy pill. A switch is possible, but only with your prescriber, as doses do not convert directly.

If you are losing weight well and tolerating your current medicine, there may be no reason to change. Your prescriber will advise which Foundayo dose to start on, if switching is right for you.

Missed doses

If you miss a Foundayo UK dose, take it as soon as you remember on the same day. Never take two tablets in one day to catch up.

If you miss several days in a row, speak to your prescriber before restarting. You may need to restart at a lower dose to avoid side effects.

Storage and travel

Foundayo UK tablets do not need to be kept in the fridge. Store the tablets at room temperature in their original packaging.

Keep Foundayo UK packs away from direct heat and moisture, so avoid leaving them in a hot car or a steamy bathroom. A simple weekly pill organiser can help you remember your daily Foundayo UK dose, especially in the first few months.

That makes Foundayo UK holidays and work trips easy. Take your prescription and enough tablets for the whole trip, and keep them in your hand luggage.

Diet and exercise

Foundayo UK treatment works best alongside a reduced-calorie diet and more activity. Eating enough protein matters, because rapid weight loss can include some muscle loss.

• Protein at every meal
• Plenty of vegetables and fibre
• Two or three strength sessions a week
• Daily walking
• Limited alcohol

Our GLP-1 and muscle loss guide explains how to protect muscle.

Buying safely

With any new medicine, fake products soon appear online. Only buy Foundayo UK stock with a prescription from a regulated UK pharmacy or online doctor.

• Check the pharmacy is registered with the General Pharmaceutical Council
• Expect a proper medical consultation
• Avoid sellers on social media or without a prescription
• Never buy “research” orforglipron

Our research peptides UK legal guide explains the risks of unlicensed products.

What comes next?

Foundayo UK availability is part of a new wave of GLP-1 pills. More competition between Foundayo, the Wegovy pill and future medicines may bring prices down over time.

Lilly is also developing retatrutide, an injection that produced even larger weight loss in trials. Our retatrutide vs tirzepatide guide covers it.

Key dates

Date	Milestone
August 2026	MHRA approves Foundayo for weight management and type 2 diabetes
24 August 2026	Foundayo UK launch in pharmacies on private prescription
November 2026	NICE final guidance expected
2027	Possible NHS prescribing, if NICE recommends it

The Foundayo UK launch came only weeks after approval, making Britain the first European country with access. Future dates depend on NICE and may change.

Getting a prescription

Foundayo UK prescriptions come from private online doctors, high-street pharmacies and private clinics. The process is similar to other GLP-1 medicines.

• Complete an online or in-person consultation
• Share your height, weight and medical history
• Some providers ask for a photo or ID check
• A prescriber reviews whether Foundayo is safe and suitable
• Your tablets are dispensed and delivered

A good Foundayo UK provider will review you regularly, check your progress and help you move through each dose. Avoid any seller that skips the medical questions.

Your first month on Foundayo

The first month of Foundayo UK treatment starts on 0.8mg, a low dose designed to help your body adjust. Many people notice only mild effects, such as feeling full sooner.

Weight loss in the first month is usually modest. The bigger changes tend to come later, once you reach higher doses.

• Take your tablet at the same time each day
• Eat smaller meals and stop when full
• Drink plenty of water
• Note any side effects in a diary
• Weigh yourself once a week

Foundayo UK prescribers usually check in before your first increase to 2.5mg.

Cost over a year

Because the dose rises over time, Foundayo UK costs change through the first year. Based on example prices from one provider, the first year on the fastest route to 17.2mg works out at roughly £1,970.

Staying on a lower maintenance dose costs less. Longer plans and multi-month bundles can also lower the monthly price at some Foundayo UK providers.

Always check what is included: consultations, delivery and ongoing reviews can add to the total.

Foundayo and type 2 diabetes

Foundayo UK licensing also covers blood sugar control in adults with type 2 diabetes. In the ATTAIN-2 trial, people with diabetes lost weight and improved their blood sugar control.

Weight loss in people with diabetes was lower than in ATTAIN-1, which is common with GLP-1 medicines. If you take insulin or sulfonylureas, your doses may need adjusting to avoid low blood sugar.

Myths and facts

Myth	Fact
Foundayo is the same as the Wegovy pill	It is a different medicine, orforglipron, with no food rules
Foundayo is on the NHS	It is private only for now
Pills work as well as injections	Injections such as Mounjaro gave larger average weight loss in trials
You can buy it without a prescription	Foundayo UK supply is prescription only

Knowing the facts helps you choose the right Foundayo UK option, or decide whether another medicine suits you better.

Common mistakes

• Moving up doses faster than once a month
• Taking two tablets to make up for a missed dose
• Buying from unregulated websites
• Expecting injection-level results from a pill
• Ignoring protein and strength training

Avoiding these mistakes makes Foundayo UK treatment safer and more effective. If in doubt, ask your prescriber.

Choosing a provider

Foundayo UK providers differ on price, support and how often they review you. A cheap headline price is not always the best value.

• Is the price fixed at every dose, or does it rise?
• Are consultations and reviews included?
• How quickly are Foundayo UK orders delivered?
• Can you speak to a clinician if you have side effects?
• Is the pharmacy registered with the General Pharmaceutical Council?

Comparing two or three Foundayo UK providers on these points can save money and give you better support over the year.

Realistic expectations

Trial averages are a guide, not a promise. Some Foundayo UK patients will lose more than 11%, others less, depending on dose, diet, activity and genetics.

Results also take time. The strongest effects in ATTAIN-1 appeared after more than a year, once people had reached and stayed on their maintenance dose.

Setting realistic goals with your prescriber helps you stay motivated. A steady loss of 5 to 10% already brings real health benefits, such as better blood pressure and blood sugar.

Questions to ask your prescriber

• Is Foundayo, the Wegovy pill or an injection best for me?
• Which dose should I start on?
• How long should I stay on each dose?
• Do any of my other medicines interact with it?
• What will treatment cost over a year?

These questions help you decide whether Foundayo UK treatment fits your goals and budget.

Key takeaways

• Foundayo is a once-daily orforglipron tablet from Eli Lilly
• It has been in UK pharmacies since 24 August 2026
• It can be taken any time, with or without food
• The highest dose gave 11.2% average weight loss over 72 weeks
