Foundayo is the brand name for orforglipron, a once-daily prescription GLP-1 tablet from Eli Lilly used for weight management and type 2 diabetes in approved patients.
The medicine was approved in the United States in April 2026 and authorised in the United Kingdom in August 2026, making the UK the first European country to approve it.
This article is general information, not medical advice. Foundayo is prescription-only and should be used under the care of a qualified healthcare professional.
What is Foundayo?
Foundayo belongs to the GLP-1 receptor agonist class of medicines.
GLP-1 medicines affect appetite, blood sugar and digestion. Other well-known drugs in this broader category include injectable products, but Foundayo is taken as a tablet.
What is the active ingredient?
The active ingredient is orforglipron.
Lilly sells Foundayo in multiple tablet strengths and uses dose escalation under medical supervision rather than starting everyone at the highest strength.
Is Foundayo approved in the UK?
Yes. The UK Medicines and Healthcare products Regulatory Agency authorised orforglipron on 10 August 2026 for approved weight-management and type 2 diabetes uses.
The MHRA said the authorisation covers eligible adults with obesity and some adults who are overweight and have weight-related health conditions, alongside diet and physical activity.
Is Foundayo available on the NHS?
Authorisation by the MHRA does not automatically mean unrestricted NHS availability.
Access depends on NHS commissioning and treatment guidance as well as clinical eligibility. Patients should check current NHS guidance or speak with a qualified prescriber rather than assuming a private approval date equals routine NHS supply.
How is Foundayo taken?
Lilly says Foundayo is taken by mouth once daily and can be taken with or without food.
The tablet should be swallowed whole. Dosing and dose increases are medical decisions and should follow the prescribing information provided by the healthcare professional.
How is it different from injectable GLP-1 medicines?
The biggest practical difference is that Foundayo is a tablet.
That may appeal to people who are uncomfortable with injections, but convenience does not mean the drug is suitable for everyone or that side effects disappear.
How much does Foundayo cost in the United States?
LillyDirect lists self-pay pricing starting at US$149 per month for some lower strengths, with different pricing at higher strengths and temporary offers that can change.
Commercial insurance and eligibility programs can result in different out-of-pocket costs.
UK private prices are set by providers and pharmacies rather than simply converting the US price into pounds.
What are the important safety warnings?
Foundayo has important warnings and contraindications in its prescribing information.
Lilly’s US medication guide includes a boxed warning about a potential risk of thyroid C-cell tumours based on animal studies. It says the medicine should not be used by people with a personal or family history of medullary thyroid carcinoma or people with Multiple Endocrine Neoplasia syndrome type 2.
Its prescribing information also discusses risks including pancreatitis, severe gastrointestinal reactions, kidney injury related to dehydration, gallbladder disease, hypoglycaemia in some patients, and other complications.
Anyone considering the medicine should review these risks with a qualified healthcare professional who knows their medical history.
What side effects can occur?
GLP-1 medicines commonly cause gastrointestinal side effects such as nausea, diarrhoea, vomiting or constipation in some users.
Side-effect frequency and severity depend on the individual and dose. Serious or persistent symptoms require medical attention.
Is Foundayo the same as Ozempic?
No. Foundayo contains orforglipron. Ozempic contains semaglutide.
They belong to the same broader GLP-1 treatment class but are different medicines with different formulations, approved uses and prescribing information.
Recent comparisons reported by Lilly are indirect analyses rather than a head-to-head trial between the two products.
Can you buy Foundayo without a prescription?
Legitimate Foundayo is a prescription medicine.
Websites claiming to sell it with no medical assessment or prescription should be treated cautiously, especially if the seller cannot be verified as a regulated pharmacy.
How to avoid fake Foundayo
Weight-loss medicines are frequently impersonated by counterfeit sellers because demand is high.
Use regulated pharmacies and recognised prescribing services. Be suspicious of social-media sellers offering unusually cheap tablets, “research” versions or products shipped loose without normal pharmacy packaging.
What does the latest research say?
Lilly has continued publishing analyses from its clinical development program during 2026. Results differ between trial populations, doses and whether participants had type 2 diabetes.
Those figures should not be interpreted as a promise of how much weight one individual will lose.
