Missed doses
I took two Foundayo tablets by mistake
The label's rule is one tablet per day, never two the same day. For too much Foundayo, the Medication Guide says to call your healthcare provider or the Poison Help line at 1-800-222-1222, or go to the nearest emergency room right away.

The short answer
The label's rule is one tablet per day, never two the same day. For too much Foundayo, the Medication Guide says to call your healthcare provider or the Poison Help line at 1-800-222-1222, or go to the nearest emergency room right away.
What the label says
The dosing section, §2.1, sets the limit in one short sentence:
From the labelDo not take more than one tablet per day.
The Medication Guide repeats it in its missed-dose lines:
From the labelIf you miss a dose, take it as soon as possible. Do not take 2 doses of FOUNDAYO in the same day.
And it says what to do when the limit has been passed:
From the labelIf you take too much FOUNDAYO, call your healthcare provider or Poison Help line at 1-800-222-1222 or go to the nearest hospital emergency room right away.
The prescribing information has its own overdose section, §10, written for clinicians:
From the labelIn the event of an overdose, consider contacting Poison Control (1-800-222-1222) or a medical toxicologist for latest recommendations. Initiate appropriate supportive treatment according to the patient's clinical signs and symptoms. A period of observation and treatment for these symptoms may be necessary, considering the half-life of orforglipron.
Why the label speaks of observation
Orforglipron, the molecule in Foundayo, does not leave the body in a few hours. The clinical pharmacology section, §12.3, gives the number:
From the labelThe elimination half-life is approximately 29 to 49 hours after an oral dose.
That means half of a dose is still there one to two days later. A second tablet taken the same morning is not gone by the next one, and whatever it causes may last more than a day. This is the reason §10 mentions a period of observation rather than a single check.
The label does not list symptoms specific to an overdose. It says treatment follows the signs and symptoms the person has. The side effects the label reports most often are stomach ones, nausea, vomiting, diarrhea and constipation, and the Medication Guide asks you to drink fluids to reduce the chance of dehydration when they cause a loss of fluids.
What the label does not say
It does not say whether to skip the next day's tablet to make up for a double one. The missed-dose rule ("take it as soon as possible") is about a tablet that was not taken, and it does not apply in reverse. The next tablet is a question for the person on the phone, or for the prescriber.
It also does not set a different rule by strength. The guide's sentence about taking too much is the same at every step.
What helps on the phone
The person you call will want the facts in order: the strength printed on the bottle, when each tablet went down, and how you feel now. The Medication Guide already asks for the rest:
From the labelKnow the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.
That list, at hand, answers the next question before it is asked.
Oolite logs each tablet with its time, so a glance at the day answers "did I already take it?" before a second one does.
Questions people ask
Who do I call?
The Medication Guide names your healthcare provider or the Poison Help line at 1-800-222-1222. If you feel very unwell, it says to go to the nearest hospital emergency room right away.
Should I skip tomorrow's tablet to even it out?
The label does not say. Its missed-dose rule is about a dose that was not taken, not one taken twice. Ask the person you call, or your prescriber, before changing the next day.
How long will the extra tablet stay in my body?
The label gives an elimination half-life of about 29 to 49 hours, so it is not gone by the next morning. That is why the overdose section speaks of a period of observation.
What symptoms should I watch for?
The label's overdose section does not list specific symptoms. It says treatment follows the person's signs and symptoms. The side effects the guide lists most often are stomach ones, such as nausea, vomiting and diarrhea, and it asks you to drink fluids to avoid dehydration.
