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.

Changing your dose day

You can change your weekly injection day as long as the last dose was at least 3 days (72 hours) earlier.

Why GLP-1 doses go up slowly
Read the transcript
  1. GLP-1 doses start low. Zepbound starts at 2.5 mg, a starter dose that gives your gut time to adjust.
  2. 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.
  3. Stomach side effects like nausea often flare for a few days after each increase, then settle on the same dose.
  4. Staying on a dose longer is common and allowed by the label. Never increase faster than your prescription says.
