I switched from injectable to oral semaglutide for travel reasons and the fasting window is proving harder to hold than the injection ever was.
What I am after 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.
Taking the question as asked, rather than the general version of it. 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.
That is the short version; the long version is somebody else's post.

labquiet_amy has the substance of this right. The condition it depends on is worth stating. 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 hans_munich describes. Oral semaglutide is absorbed in the stomach with the help of SNAC, which locally raises pH and protects the peptide long enough to cross. That mechanism is fragile: bioavailability is roughly 1% and highly sensitive to gastric contents, so a mouthful of coffee genuinely changes the exposure. This is why the label wants 30 minutes and no more than half a glass of plain water.
Adding the clinical framing, because it changes how the question reads. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.
I would rather be corrected than agreed with, if it comes to it.
