Levels
When does the Wegovy pill peak in your blood?
About one hour after the tablet. The label says the maximum concentration of semaglutide is reached 1 hour post dose with the tablets, against 1 to 3 days with the weekly injection. Absorption happens mostly in the stomach, which is why the morning routine matters.

The short answer
About one hour after the tablet. The label says the maximum concentration of semaglutide is reached 1 hour post dose with the tablets, against 1 to 3 days with the weekly injection. Absorption happens mostly in the stomach, which is why the morning routine matters.
What the label says
The pharmacokinetics section (§12.3) has a paragraph for each form. For the tablets, it starts with where the medicine goes in:
From the labelWEGOVY® tablets are co-formulated with SNAC which facilitates the absorption of semaglutide after oral WEGOVY® tablet administration. The absorption of semaglutide predominantly occurs in the stomach.
Then the timing:
From the labelMaximum concentration of semaglutide is reached 1 hour post dose.
For the weekly injection, the same section gives a very different clock:
From the labelMaximum concentration of semaglutide is reached 1 to 3 days post dose.
A peak on top of a level
The one hour peak is the high point after each tablet. It is not the whole story, because semaglutide leaves slowly. The same section says:
From the labelWith an elimination half-life of approximately 1 week, semaglutide will be present in the circulation for about 5 to 7 weeks after the last injectable dose of 2.4 mg or 7.2 mg or oral dose of 25 mg.
So each morning's tablet adds to what the previous days left. The level climbs over several weeks until what comes in each day matches what goes out. The Wegovy tablets label does not give that delay; the Rybelsus and Ozempic tablets label, same molecule and same kind of tablet, does:
From the labelSteady-state exposure was achieved following 4 to 5 weeks of semaglutide tablets oral administration.
The label does not say how much the level rises and falls within one day. What it makes clear is that a tablet is not gone by evening.
Why the morning routine is about that hour
Since the medicine is absorbed in the stomach, the label's instructions are about what is in the stomach at that moment. In §2.1:
From the labelAfter taking a WEGOVY® tablet, wait at least 30 minutes before eating food, drinking beverages or taking other oral medications
And in §12.3, the study behind it:
From the labelIn this study, semaglutide absorption (i.e., AUC and C max) was higher after a longer post-dose fasting period.
The label also notes that only a small share of each tablet is absorbed, approximately 1% to 2%. That is why the empty stomach, the small amount of water and the wait are part of the dose, not details around it.
Oolite's level chart is a model built from these label numbers, drawn as a percent of the level your current step settles at, never in mg. It is not a blood test.
Questions people ask
Does the one hour peak mean the pill wears off by evening?
No. The label gives semaglutide an elimination half-life of approximately 1 week. Each tablet adds to what the previous ones left, so the level is built over weeks, and the daily peak is a small rise on top of it.
Why is the injection so different?
The injection goes under the skin and is absorbed slowly: the label puts its maximum concentration 1 to 3 days after the shot. The tablet is absorbed in the stomach, with the help of an ingredient called SNAC, and peaks within the hour.
Should I feel something one hour after the tablet?
The label does not link side effects to the hour of the peak. If a symptom keeps coming back at the same time of day, note it and mention it to your prescriber.
Does waiting longer than 30 minutes change the peak?
The label says absorption, measured as total exposure and peak concentration, was higher after a longer post-dose fasting period in a study of 15 to 120 minutes. The instruction itself stays: at least 30 minutes.
