How long does Cagrilintide take to work?
In the first week of Cagrilintide, mild appetite drop. Less nausea than the GLP-1 drugs. Around week 4, first titration step. Modest weight loss alone, stronger when stacked with semaglutide. By week 8, steady-state. Best results in 'CagriSema' combination with semaglutide. Response varies between people, this is the commonly reported pattern, not a guarantee.
