Orforglipron Dosage

Oral non-peptide GLP-1 agonist

Orforglipron is an oral non-peptide GLP-1 pill, so its dosing involves no reconstitution or insulin-syringe math. The mg figures here trace to published trials rather than serving as a substitute for the current label. Phase 2 obesity tested once-daily 12, 24, 36, and 45 mg; Phase 3 obesity (ATTAIN-1) used 6, 12, and 36 mg; Phase 3 diabetes (ACHIEVE-1) used 3, 12, and 36 mg.[1][2][3]

Dosing

Because it is an oral tablet, orforglipron has no reconstitution or syringe math. Trials used once-daily oral doses reached through gradual escalation. The doses below describe what was studied, not a substitute for the current prescribing label:

ProgramOnce-daily oral doses studied
Phase 2 obesity (2023)12, 24, 36, 45 mg
Phase 3 obesity (ATTAIN-1)6, 12, 36 mg
Phase 3 diabetes (ACHIEVE-1)3, 12, 36 mg
Figures are the once-daily oral doses tested in published trials, reached through staged escalation. Follow the current label and a prescriber for real use.

Each program reached its target dose through staged escalation, stepping up over several weeks so the gut can adjust, which is how the trials aimed to keep gastrointestinal effects tolerable. Treat these numbers as a description of what was studied; for real use, follow the current product label and a prescriber.
