What it's approved for
- Improving blood sugar control, with diet and exercise, in adults with type 2 diabetes
- Not approved for weight management
How it works
It mimics GLP-1, a gut hormone released after meals. It slows stomach emptying, lowers appetite and helps the pancreas release insulin when blood sugar is high.
Rybelsus has a half-life of about 1 week for the injection, so steady levels take 4 to 5 weeks.
The same medicine is sold as Wegovy pill. See Wegovy pill vs Rybelsus.
Dose steps on the label
Increase after at least 30 days on the current dose. Maintenance: 7 mg or 14 mg once daily (a newer tablet formulation uses 1.5 mg, 4 mg and 9 mg strengths; check your label).
What the main trials found
PIONEER program: A1C fell about 1.0 to 1.4 points at 14 mg, with modest weight loss of a few pounds to about 9 lb.

Read the transcript
- After you eat, your gut releases a hormone called GLP-1. GLP-1 medicines copy it, but last much longer in the body.
- It slows how fast your stomach empties, so you feel full sooner and stay full for longer.
- It also acts on appetite centers in the brain, which quiets hunger and constant thoughts about food.
- When blood sugar is high, it helps the pancreas release insulin. Tirzepatide also acts on a second gut hormone, GIP.
