Foundayo Eligibility: Who Can Take It
Foundayo is licensed for adults with a BMI of 30 or above, or a BMI of 27 to below 30 with at least one weight-related condition, and separately for improving blood sugar control in adults with type 2 diabetes. According to the UK licensing, the only absolute contraindication is hypersensitivity to orforglipron or any of its ingredients. However, our pharmacy applies additional prescribing criteria, and we will not prescribe Foundayo to anyone with a personal history of pancreatitis. Foundayo should not be used during pregnancy or breastfeeding or combined with another GLP-1 medicine. Tell your prescriber about any personal or family history of thyroid cancer so they can assess your circumstances against UK prescribing information and pharmacy criteria. Some other conditions — such as severe digestive conditions or diabetic eye disease — require individual assessment rather than ruling treatment out automatically. Your clinical team will review your full medical history during your consultation before any prescription is issued.
Foundayo's core eligibility criteria mirror those used across the GLP-1 weight-management class in the UK:
- A BMI of 30 or above, or a BMI of 27 to below 30 with at least one weight-related condition such as high blood pressure, high cholesterol, or type 2 diabetes
- Aged 18 or over
- Willing and able to follow the accompanying dietary and lifestyle guidance, since Foundayo is licensed for use alongside a reduced-calorie diet and increased physical activity, not as a standalone treatment
Foundayo also holds a separate UK licence for improving blood sugar control in adults with insufficiently controlled type 2 diabetes, alongside diet and exercise. Our orforglipron diabetes guide explains that separate indication. These weight-management criteria do not confirm access to diabetes treatment through Happy Pharmacy.
When Foundayo Is Unsuitable or Needs Prescriber ReviewThe table distinguishes a formal UK contraindication, uses that are not recommended, and situations requiring prescriber review. Happy Pharmacy also applies its own additional prescribing criteria. If you are considering treatment during perimenopause or menopause, our Foundayo menopause guide covers the evidence and HRT and contraception questions to raise during your assessment.
| Situation | Why |
|---|---|
| Hypersensitivity to orforglipron or any excipient | The only absolute contraindication in the UK licensing |
| Personal or family history of medullary thyroid carcinoma or MEN 2 | Requires prescriber review and disclosure of family history; this is not listed as an absolute contraindication in the UK Foundayo prescribing information |
| Pregnant, breastfeeding, or trying to conceive | Do not use during pregnancy or breastfeeding. Stop at least 3 weeks before a planned pregnancy; if pregnancy occurs, stop and contact your prescriber |
| Already taking another GLP-1 receptor agonist | Combining GLP-1 medicines, including with each other, isn't recommended |
| Severe hepatic impairment | Not recommended — orforglipron exposure is substantially increased in severe liver impairment |
| Severe heart failure (NYHA class IV) | Not recommended, due to a lack of clinical experience in this group |
| Personal history of pancreatitis | Happy Pharmacy's own additional prescribing criteria — orforglipron hasn't been specifically studied in this group |
Several other situations don't automatically rule out Foundayo, but do need individual assessment with your prescriber, who will weigh your specific circumstances before deciding whether — and how cautiously — to proceed.
Severe Gastrointestinal Disease
Conditions like severe gastroparesis (delayed stomach emptying) haven't been specifically studied with Foundayo, and since the medicine itself further slows gastric emptying, this needs careful individual assessment.
Diabetic Retinopathy or Macular Oedema
If you have a history of diabetic eye disease, Foundayo can be used with caution, but your prescriber will want to monitor for any progression, consistent with guidance across the GLP-1 class.
Mild to Moderate Hepatic Impairment
No dose adjustment is needed for mild or moderate liver impairment, but it's still important information for your prescriber to have as part of your overall assessment.
Renal Impairment
Reassuring detail
Unlike some medicines, no dose adjustment is needed for Foundayo in people with kidney impairment, including end-stage renal disease — studies found no meaningful change in how the drug behaves in the body across this group. Your prescriber will still monitor kidney function if you experience side effects that could lead to dehydration, such as persistent vomiting or diarrhoea.
Taking Hormonal Contraceptives
Foundayo may reduce oral hormonal contraceptive effectiveness. Use a non-oral method or add a barrier method for 30 days after starting and after each dose increase. Discuss your plan with your prescriber; see our Foundayo side effects guide.
Insulin, Sulfonylureas and Low Blood Sugar
Insulin or sulfonylurea treatment may increase the risk of low blood sugar when combined with Foundayo. Your prescriber may adjust those medicines and arrange glucose monitoring. Do not reduce or stop diabetes medication yourself.
Taking Medicines That Affect Liver Enzyme Metabolism
Some medicines need to be avoided with Foundayo; others require a dose limit or monitoring. Certain strong CYP3A4 inhibitors or OATP1B inhibitors limit the daily Foundayo dose to 9mg, while strong CYP3A4 inducers should be avoided. Some statin doses also need adjustment. Give your prescriber a full list of prescriptions, over-the-counter medicines and supplements. Do not adjust any medicine yourself; see the Foundayo dosage guide.
Foundayo is one of a small number of GLP-1 medicines authorised in the UK for two separate purposes: weight management in adults meeting the BMI criteria above, and improving blood sugar control in adults with insufficiently controlled type 2 diabetes, used alongside diet and exercise. These are assessed as genuinely separate clinical indications — eligibility for one doesn't automatically confirm eligibility for the other, and your prescriber will consider which licensed use applies to your specific circumstances during your consultation.
Age and Other General ConsiderationsFoundayo is licensed for adults. No dose adjustment is required solely because of age, but evidence in people aged 85 and over is very limited. Older adults and people with several medical conditions need an individual assessment of suitability and monitoring.
If You Don't Meet the Criteria TodayIf Foundayo is unsuitable, your prescriber can discuss other approaches. Mounjaro and Wegovy injections also have eligibility criteria and are not automatic alternatives if you fall below the licensed weight-management BMI thresholds. A change in your health can justify reassessment, but meeting a BMI threshold alone does not guarantee a prescription.
Why Eligibility Criteria ExistIt's worth understanding that eligibility criteria aren't arbitrary hurdles — they reflect where the clinical evidence is genuinely strongest and safest. Many of the situations above (severe gastroparesis, a history of pancreatitis, significant liver impairment) simply weren't well represented in Foundayo's clinical trial programme, which means there isn't robust safety data to confirm how the medicine behaves in those specific circumstances. Rather than guessing, careful individual assessment — or in some cases, a different treatment altogether — protects you from being prescribed something without the evidence base to support it being both safe and effective for your particular situation.
What Happens During Your Eligibility AssessmentYour eligibility must be confirmed through a free online consultation with our GPhC-registered pharmacy team. This covers your current BMI and weight history, any existing health conditions (particularly those listed above), your full current medication list including any supplements, and your family medical history where relevant — particularly regarding thyroid conditions. This isn't a formality; it's a genuine clinical review designed to confirm Foundayo is an appropriate and safe choice for you specifically, not just a box-ticking exercise before a sale.
Important
Always disclose your complete medical history and current medications during your consultation, even details that feel unrelated or embarrassing to mention. Eligibility criteria exist to protect your safety, not to create unnecessary hurdles — omitting relevant information can lead to a treatment being prescribed when it genuinely isn't the right or safest choice for you.
