The two peptides hit different receptors and pathways, so there's no known direct interaction
Unexpectedly, although the expression of the GLP-1R gene in the untreated Pla2g6 / mice did not differ from WT controls, treatment with semaglutide resulted in up-regulation of GLP-1R expression suggesting a feed-back loop upon activation of the receptor
Managing side effects Side effects are the most common reason people discontinue semaglutide or fail to reach therapeutic doses
