Example Orforglipron Titration Schedule
FDA‑Approved Dosing Protocol (Foundayo®)
Orforglipron is taken as a once‑daily oral tablet with or without food. The dosing protocol follows a monthly titration schedule across six color‑coded dose strengths, with a maximum dose of 17.2 mg once daily.
Step Dose Strength Duration
1 (Starting dose) 0.8 mg once daily At least 4 weeks
2 (Titration) 2.5 mg once daily At least 4 weeks
3 (Titration) 5.5 mg once daily At least 4 weeks
4 (Titration) 9 mg once daily As tolerated
5 (Titration) 14.5 mg once daily As tolerated
6 (Maximum dose) 17.2 mg once daily Maintenance

Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
Orforglipron Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
It's a once-daily oral GLP-1 receptor agonist from Eli Lilly, now sold under the brand name Foundayo. Unlike injectable GLP-1s, it's a small-molecule pill (not a peptide), so it isn't reconstituted, mixed, or injected — you swallow a tablet. It's also the first GLP-1 pill that can be taken any time of day without food or water restrictions.
Yes. The FDA approved it on April 1, 2026 as Foundayo, for adults with obesity or overweight with a weight-related condition, used alongside diet and exercise. That makes it one of the first oral GLP-1 options for weight management, after oral semaglutide (the Wegovy pill) was approved in December 2025.
Foundayo is a once-daily tablet taken at the same time each day, with or without food. The approved dose ladder steps up gradually — 0.8, 2.5, 5.5, 9, 14.5, up to a 17.2 mg maintenance dose — to ease stomach side effects. Because it's a fixed-strength pill, there's no measuring or mixing involved; the exact schedule is set by a prescriber.
No. Tirzepatide (Mounjaro/Zepbound) is an injectable peptide that acts on two receptors (GLP-1 and GIP). Orforglipron is an oral, non-peptide pill that acts on GLP-1 only. They're different molecules in different formats — orforglipron isn't an oral version of tirzepatide, even though both come from Eli Lilly.
Yes — orforglipron is one of the first. Most GLP-1 drugs are peptides that stomach acid breaks down, so they're injected; orforglipron is a small molecule that survives digestion, which is why it works as a daily tablet. Oral semaglutide (the Wegovy pill) is another oral option. A pill format means no needles, vials, or reconstitution at all.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
