Byetta is not approved for weight loss, so there is no weight-loss timeline of its own to quote. What its label does set is how quickly the dose is raised, below.
When Byetta reaches its full dose
- Month 1: 5 mcg twice daily — Within the 60 minutes before the morning and evening meals.
- Month 2 on: 10 mcg twice daily — Recommended after 1 month, based on response.
When to reassess
The Byetta label sets no time point for judging whether it is working. Ask your prescriber when they plan to review your response, and do not change the dose on your own.
