- 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.
