About the 12.5 mg Dose
The 12.5 mg dose is the penultimate escalation step for Mounjaro and Zepbound, used during weeks 17 through 20 before reaching the 15 mg maximum. Patients at this dose have been titrating for four months and are nearing the full therapeutic level. This dose bridges the gap between 10 mg and the 15 mg maintenance dose.
