Titration timeline
FDA-labeled step-up schedule. Most clinicians follow this exactly, but may pause at a step for an additional 4 weeks if side effects are intolerable.
- 1
Weeks 1–4
5 mcg twice daily
Initiation dose. Inject within 60 minutes before morning and evening meals.
- 2
Week 5+
10 mcg twice daily
May step up after 1 month based on tolerability and glycemic response.
If a step-up is poorly tolerated
Patients who cannot tolerate 5 mcg twice daily after 4 weeks should discontinue. Most prescribers transition exenatide-treated patients to a once-weekly GLP-1 for adherence.

If a dose is missed, skip it and resume at the next scheduled meal — do NOT inject after eating. Never take two doses at once.
