Where 2.5 mg sits on the ladder
What the label says
Zepbound 2.5 mg: Starting dose. It is not a maintenance dose: it gives your gut time to adjust.
This is the starting dose. Its job is to let your stomach adjust; the label doesn't use it as a maintenance dose. Stomach side effects are most likely in these first weeks.
