What the study found
Semaglutide lingers in the blood for five to seven weeks
This is why side effects do not stop the day you do. Semaglutide's half-life is about a week, and the label puts measurable drug in the blood for five to seven weeks after a final 2.4mg dose. It also slows stomach emptying, which can change how other tablets are absorbed.
The caveat · From the maker's own drug studies
These are label figures from the manufacturer's own pharmacokinetic studies, measured in trial participants rather than in general use. The label flags the interaction with oral medicines as something to watch rather than a quantified effect on any particular drug.
