Dosage chart
| Dose | Fastest label timing | Label note |
|---|---|---|
| 0.75 mg | Weeks 1 to 4 | Starting dose. |
| 1.5 mg | Weeks 5 to 8 | Can be increased after at least 4 weeks on 0.75 mg. |
| 3 mg | Weeks 9 to 12 | If more control is needed after at least 4 weeks on 1.5 mg. |
| 4.5 mg | Week 13 onward | If more control is needed after at least 4 weeks on 3 mg. Highest dose. |
The fastest timing assumes every increase happens as soon as the label allows. Prescribers often hold a dose longer; that's common and on-label.

- GLP-1 doses start low. Zepbound starts at 2.5 mg, a starter dose that gives your gut time to adjust.
- After at least 4 weeks, your prescriber may step it up by 2.5 mg, up to a maintenance dose of 5, 10 or 15 mg.
- Stomach side effects like nausea often flare for a few days after each increase, then settle on the same dose.
- Staying on a dose longer is common and allowed by the label. Never increase faster than your prescription says.
