Missed Semaglutide injection by 10 days due to travel: do I resume or restart?

I was traveling for work and forgot my medication vial. I am on 1.0 mg Semaglutide. My last injection was 17 days ago (10 days past my normal injection day). Can I just take my normal 1.0 mg dose tonight?

Do not take the full 1.0 mg dose tonight. Because 17 days have elapsed since your last dose, you have cleared more than two half-lives of Semaglutide. Your circulating peptide levels have dropped significantly, and your gut and brain GLP-1 receptors have lost their active down-regulation.

If you inject 1.0 mg cold after a 17-day lapse, you will likely experience severe acute nausea, projectile vomiting, and dehydration.

Clinical Protocol for Lapses > 14 Days: 1. Step back to 0.50 mg for your injection tonight. 2. If tolerated without moderate GI symptoms, you can resume your regular 1.0 mg dose in 7 days. 3. If any severe symptoms occur, step back to the 0.25 mg starter dose for 2 to 4 weeks to rebuild receptor tolerance safely.
