Quick answer

Foundayo reaches its peak level in the blood four to eight hours after a dose, with steady levels after around one week of daily tablets. Treatment starts at 0.8 mg once daily for at least 30 days. Some patients start to see weight changes from around week two, while others take longer to respond. In a large clinical trial called ATTAIN-1, patients lost around 12% of their total body weight on average over 72 weeks.

Key takeaways

The Foundayo prescribing information gives a time to maximum concentration of four to eight hours and steady levels after around one week of daily doses.
Foundayo has a half-life of around 29 to 49 hours, shorter than that of the weekly injections, which is why it is taken once a day.
Foundayo can be taken with or without food, at any time of day, which can make it easier to fit into a daily routine.
The prescribing information reports digestive side effects such as nausea and constipation more often than other side effects.
Each dose step lasts at least 30 days, and your endocrinologist will agree any increase with you at the monthly follow-up.
The Emirates Drug Establishment approved Foundayo for chronic weight management in April 2026, and the US prescribing information approves it for adults only.
Foundayo is not for use in pregnancy or while breastfeeding, and the prescribing information advises extra contraception alongside an oral contraceptive pill for the first 30 days.

In one line: Foundayo does not need to be taken on an empty stomach, unlike the Wegovy pill.

01 Introduction

Foundayo (orforglipron) is a once-daily tablet that targets the same GLP-1 receptor as injectable GLP-1 weight loss medications. It helps regulate appetite and food intake, but unlike weekly GLP-1 injections, it is taken by mouth.

02 How quickly does Foundayo start working?

The Foundayo prescribing information states that orforglipron reaches its maximum concentration in the blood four to eight hours after a dose. With one tablet a day, levels in the blood become steady after around one week.

Appetite may begin to change in the first weeks, although the response differs from one patient to another. Our guide on how long weight loss injections take to work explains how this compares with the weekly injections.

03 Why is Foundayo taken every day?

Foundayo leaves the body faster than the weekly injections. The prescribing information gives its half-life as around 29 to 49 hours, which is why it is taken once a day.

Foundayo can be taken with or without food, at any time of day. Swallow the tablet whole, and do not take more than one tablet a day.

04 Week one on Foundayo

In week one, you will take 0.8 mg once a day. Side effects such as nausea or constipation can be particularly pronounced in the first few days at a new dose. They often improve as your body adjusts, although some symptoms last longer.

The prescribing information lists nausea, constipation, diarrhoea, vomiting and indigestion among the side effects reported in 5% or more of patients. Not every patient experiences them. If you experience nausea or constipation, your endocrinologist can adjust the pace of dose increases and, where needed, prescribe medication to help manage these side effects. Our page on Foundayo side effects covers each one in detail.

If you use an oral contraceptive pill, the prescribing information advises switching to a non-oral method or adding a barrier method for 30 days after starting Foundayo. The same applies for 30 days after each dose increase.

05 Weeks two to four on Foundayo

Early changes on the scale can partly reflect changes in body water, rather than fat loss alone. Early weight loss also does not necessarily continue at the same rate.

You will stay on 0.8 mg for at least 30 days. At your first monthly follow-up, your endocrinologist will review your weight, any side effects and your progress, and discuss the next step with you.

At Endocare, body composition analysis is included free of charge at every consultation. Body composition analysis estimates body fat, muscle mass and body water. Repeated measurements help your endocrinologist understand how your body is changing beyond the number on the scale.

06 After the first month: your first dose step

The next dose is 2.5 mg, after at least 30 days on 0.8 mg, and the prescribing information then sets 5.5 mg after at least another 30 days. From 5.5 mg, the dose may be increased in steps to 9 mg, 14.5 mg and 17.2 mg, with at least 30 days at each dose. Each increase depends on your response and how well you tolerate the medication.

The dose is reviewed with your endocrinologist at each monthly follow-up. The 0.8 mg and 2.5 mg doses are steps in the dose escalation, and your maintenance dose is not necessarily the highest one. Our Foundayo dosage guide explains each step and what to do if you miss a dose.

07 When do results show with Foundayo?

In ATTAIN-1, a large Phase 3 clinical trial in adults with obesity or overweight, participants taking the highest dose of orforglipron lost around 12% of their body weight on average, with some achieving 15% or more. That trial lasted 72 weeks. Its average describes the result after more than a year of treatment.

At Endocare, our endocrinologists typically observe weight loss of three to four kilos a month in patients on a medically supervised programme. Individual results vary from patient to patient.

The Wegovy pill and the weekly injections are alternatives. Our comparison of Foundayo and the Wegovy pill looks at the two tablets side by side.

08 When to contact your endocrinologist

Seek medical advice immediately if you have severe stomach pain that spreads to your back and does not go away, as this can be a sign of pancreatitis. Seek medical advice immediately if you keep vomiting or cannot keep fluids down, as this can lead to dehydration.

Foundayo should not be used during pregnancy because it may harm an unborn baby. Breastfeeding is also not recommended while taking Foundayo. Endocare’s doctors are always available to support patients with advice.

09 FAQ

Can I take Foundayo every other day?

No. Foundayo is taken once a day, every day, because it leaves the body faster than the weekly injections. Do not change how often you take it without speaking to your endocrinologist.

Why am I not losing weight on Foundayo yet?

Some patients take longer to respond, and the first month is spent on the starting dose of 0.8 mg. If your weight is not changing despite a consistent plan, it may be worth reviewing both the plan and whether any medical factors could be contributing.

Does Foundayo work as well as the weekly injections?

The leading injectable treatments still produce greater average weight loss, while Foundayo offers the convenience of a daily tablet without injections. Neither option is necessarily better. The right choice depends on your individual assessment, how well you tolerate treatment and what you can realistically sustain long term. Our comparison of Foundayo and Mounjaro explains the differences.

What should I eat during my first month on Foundayo?

Start with protein. Our coaches focus on including a good source of protein at each meal, then look at portion sizes and drinks, which can contribute significantly to daily calorie intake. Our guide to what to eat on Foundayo has practical examples.

Should I stop Foundayo if I feel unwell in the first week?

Do not stop without speaking to your endocrinologist. Mild nausea or constipation often settles. Your endocrinologist can also adjust the pace of dose increases. Seek medical advice immediately for severe stomach pain, persistent vomiting or signs of dehydration.

Where can I get Foundayo in Dubai?

Foundayo is available on prescription after a medical assessment, and UAE pharmacies listed every strength in October 2026. Our page on Foundayo in Dubai explains how to start treatment at our Dubai clinic. Our Foundayo price page explains the cost.

Start Foundayo with a medical assessment

Patients should not decide by themselves to start a GLP-1 medication. A doctor’s review is critical to ensure the treatment is safe and appropriate for the individual. The US prescribing information approves Foundayo for adults only.

At our Dubai clinic, your endocrinologist will assess you, review your blood tests and discuss whether Foundayo is appropriate for you. You can book a weight loss consultation on +971 4 285 3885 or send us a message on WhatsApp.
