I switched from injectable to oral semaglutide for travel reasons and the fasting window is proving harder to hold than the injection ever was.
The practical numbers: about 1% oral bioavailability, 30 minutes fasted before food, no more than 120ml of plain water, and coffee counts as food for this purpose.
What I am trying to establish is whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong.
I have searched first, so if this is covered somewhere point me at it and I will read it.
This one has a reasonably settled answer, so here it is. Orforglipron is the more interesting oral story because it is not a peptide at all. Being a small molecule it does not need SNAC, does not need the fasting window, and has oral bioavailability in the tens of percent rather than about one.

That is correct as far as it goes, and here is where it stops going. Worth adding that the tablet is taken daily, so a missed dose costs far less than a missed weekly injection. That is a genuine advantage nobody lists.

Can confirm the pattern COA_Karl describes. The OASIS programme put 50mg oral in the same territory as 2.4mg injectable — around 15% mean weight loss — but it needed a dose 20 times larger to get there because almost none of the tablet is absorbed. The dose numbers are not comparable across routes and quoting them side by side confuses people.
From the other side of the consultation, briefly. Worth answering the question that was asked rather than the one behind it. The narrow version usually has an answer; the broad version usually does not, and answering the broad one is how a thread stops being useful.
