How to take Foundayo: one tablet a day, no fasting rules
Take one Foundayo tablet by mouth once a day, with or without food, at whatever time suits you. Swallow it whole with any drink — there is no empty-stomach window, water limit or 30-minute wait, unlike oral semaglutide. Start at 0.8 mg and step up no sooner than every 30 days, as your prescriber directs.
Before you start
Foundayo is orforglipron, a once-daily GLP-1 tablet from Eli Lilly, FDA-approved in 2026 for chronic weight management in adults with obesity, or overweight plus a weight-related condition. It is a small-molecule drug, not a peptide, and unlike oral semaglutide its label sets no fasting rules. Before starting, tell your prescriber about any personal or family history of medullary thyroid carcinoma or MEN 2, which rule it out, and about pancreatitis, gallbladder disease, severe gastroparesis, severe liver impairment, diabetic eye disease, pregnancy or breastfeeding. Bring a full medicine list: strong CYP3A4 inhibitors and inducers, simvastatin, and oral contraceptives all change how it is used. Do not combine it with another GLP-1 medicine. Have your first bottle of 0.8 mg tablets in hand, and note the start date so you know when 30 days have passed.
Step by step
Pick a daily anchor
The label says once daily, with or without food, and names no required hour. That leaves the timing to you, so tie the tablet to something you already do every day — breakfast, brushing your teeth, or an evening routine. A consistent anchor is simply the easiest way not to miss a dose.
Take exactly one tablet
Take one tablet of the strength you were prescribed. The label is explicit that you should not take more than one tablet per day, including to make up for a missed dose. If you have bottles of two strengths at home during a dose change, check the strength on the label before you open one.
Swallow it whole
Swallow the tablet whole. Do not break, crush or chew it, according to the prescribing information. If you find tablets hard to swallow, raise it with your prescriber or pharmacist rather than splitting it; splitting also will not give you an in-between dose, since each strength is a separate tablet.
Eat and drink as normal
There is no limit on water, no ban on coffee, and no wait before breakfast or other tablets. In Lilly's food study, a meal lowered total exposure by about 19%, which the label judges not clinically relevant. Levels peak 4 to 8 hours after a dose regardless of whether you have eaten.
Check the tablet you were given
Each strength looks different. The 0.8 mg tablet is pink and round, 2.5 mg light yellow round, 5.5 mg grayish purple round; 9 mg, 14.5 mg and 17.2 mg are modified ovals in the same three colors, debossed "Lilly" and G4 to G6. If a refill looks unfamiliar, ask the pharmacy before taking it.
Step up only on schedule
Stay on each strength for at least 30 days before moving up, and only when your prescriber tells you to. The label's escalation exists to reduce stomach side effects, and in its trials nausea, vomiting and diarrhea were most common during escalation. Never double a lower tablet to reach the next strength yourself.
Tell your prescriber about new medicines
Drugs that act on the liver enzyme CYP3A4 change Foundayo levels. The label caps Foundayo at 9 mg daily alongside a strong CYP3A4 inhibitor such as clarithromycin, advises avoiding strong inducers such as carbamazepine, and limits simvastatin to 20 mg daily. Mention Foundayo whenever any new prescription is written.
Schedule
The label's starting dose is 0.8 mg once daily. After at least 30 days, it rises to 2.5 mg, and after at least 30 days on that, to 5.5 mg. From there your prescriber may move you to 9 mg, then 14.5 mg, then 17.2 mg, each after at least 30 days on the current strength and based on how well it is working and how you tolerate it. The maximum is 17.2 mg once daily, or 9 mg with a strong CYP3A4 inhibitor. Each bottle holds 30 tablets, which lines up with the 30-day steps. Steady levels are reached after about one week of daily dosing.
How and where to take it
Foundayo is a tablet, so there are no injection sites. The things that matter instead are how you swallow it and what you take it with. Swallow it whole with a drink of your choice; the label sets no volume limit and no restriction to plain water. You can take it with a meal or without one, which is the main practical difference from oral semaglutide. Its half-life of 29 to 49 hours means timing within the day is forgiving. If you take other tablets whose absorption matters, the label notes Foundayo slows stomach emptying.
Storage
Store Foundayo at room temperature, 68°F to 77°F (20°C to 25°C). Short excursions between 59°F and 86°F (15°C to 30°C) are permitted under the label's controlled room temperature rule. It does not need refrigeration, and no cold pack is needed for travel. The tablets come in bottles of 30 with a desiccant and a child-resistant cap; keep them in that bottle with the lid closed and the desiccant inside. Do not leave the bottle anywhere that could pass 86°F, such as a parked car, and keep it out of children's reach.
If you miss a dose
If you miss a dose, take it as soon as possible, as the label directs. Do not double up the next dose to make up for it, and never take two tablets in one day. The rule that changes things is length: if you miss 7 or more doses in a row, the label says to restart dose escalation at a lower strength to reduce the risk of stomach side effects. Contact your prescriber before restarting after a gap of a week or longer.
If you take too much
Taking more than prescribed is most likely to cause severe nausea, vomiting, diarrhea or dehydration, and low blood sugar in people also using insulin or a sulfonylurea. The label advises contacting Poison Control on 1-800-222-1222 or a medical toxicologist, with supportive care guided by symptoms. Because the half-life runs 29 to 49 hours, observation may be needed for a day or more. Seek emergency care if you cannot keep fluids down, or feel confused, shaky, sweaty or faint.
What to avoid
Do not use Foundayo with another GLP-1 medicine. If you use birth control pills, switch to a non-oral method or add a barrier method for 30 days after starting and for 30 days after each dose increase. Do not start a new prescription or supplement without checking it for CYP3A4 effects. Avoid dehydration during stomach side effects. Stop and tell your prescriber if you become pregnant, and tell any surgeon or anesthetist you take it before a procedure.
Frequently asked questions
Do I need to take Foundayo on an empty stomach?
No. The prescribing information says to take it once daily with or without food. That separates it from oral semaglutide — Rybelsus and the Wegovy pill — which must be taken on waking with no more than 4 ounces of plain water and a 30-minute wait. Lilly's food study found a meal lowered total exposure by about 19%, and the label concludes this is not a clinically relevant effect, so there is no reason to fast.
What time of day should I take Foundayo?
Any time. The label does not name a required hour or ask for the same time every day. A consistent time makes it easier to remember, and if a morning dose leaves you queasy, the label allows you to take it later in the day instead. Because orforglipron's half-life is 29 to 49 hours, taking a dose a few hours earlier or later than usual does not create a meaningful gap. Steady levels build over about the first week.
Can I drink coffee with Foundayo?
Yes. The label places no restriction on which drink you take it with, and no required wait before coffee, tea or breakfast. That is one of the practical differences from oral semaglutide, whose label requires plain water only, up to 4 ounces, and a 30-minute wait. The label does list gastroesophageal reflux disease among Foundayo's common side effects, affecting 6% to 7% of patients in its trials, so tell your prescriber if heartburn becomes a problem.
What happens if I miss several days?
For one missed dose, take it as soon as possible and carry on, without doubling up. For a longer gap the label draws a line at 7 consecutive missed doses: at that point you should restart the dose escalation at a lower strength rather than resume where you stopped, because restarting at full strength raises the chance of nausea and vomiting. Your prescriber decides which lower strength to use and how quickly to step back up.
Can I split or crush a Foundayo tablet?
No. The label says to swallow tablets whole and not to break, crush or chew them. Splitting would also not produce a reliable intermediate dose, because each of the six strengths — 0.8, 2.5, 5.5, 9, 14.5 and 17.2 mg — is a separate tablet. If you cannot tolerate your current strength, talk to your prescriber about staying on it longer or stepping down, rather than trying to adjust the amount yourself. A pharmacist can also confirm the strength if tablets from two bottles get mixed up.
What are the most common side effects of Foundayo?
Stomach effects. In the label's pooled placebo-controlled trials, nausea affected 26% on 5.5 mg, 34% on 9 mg and 35% on 17.2 mg, against 10% on placebo. Constipation, diarrhea, vomiting and indigestion were also common. The label reports these were most frequent during dose escalation and decreased over time. About 8% of Foundayo-treated patients stopped treatment because of side effects, compared with 3% on placebo, mostly because of stomach symptoms. Severe or persistent symptoms need a call to your prescriber.
Does Foundayo affect birth control pills?
It can. The label says Foundayo may reduce how well oral hormonal contraceptives work, because it slows stomach emptying. If you take the pill, switch to a non-oral method or add a barrier method such as condoms for 30 days after you start Foundayo and for 30 days after each dose increase. The label's advice is aimed at oral contraceptives specifically. The label also advises effective contraception throughout treatment, because Foundayo may cause fetal harm.
Where do I get Foundayo and what does it cost?
Foundayo is dispensed through Eli Lilly's LillyDirect pharmacy. Temi's Foundayo page lists $149 for a 30-day supply of the 0.8 mg tablet (usetemi.com/medications/foundayo, checked 28 Sep 2026), and notes that Temi does not fill it through its own checkout. Higher strengths may be priced differently. Lilly sets these prices and can change them, so confirm the current amount with LillyDirect before each fill, and ask your prescriber whether a Temi clinician review suits your situation.
