Key facts about Orforglipron
What dosages is Orforglipron available in?
Orforglipron is available as 0.8 mg, 2.5 mg, 5.5 mg, 9 mg, 14.5 mg, and 17.2 mg oral tablets. Treatment is typically initiated at a lower dose and titrated upward over time as directed by your healthcare provider.
What is Orforglipron used for?
Orforglipron is indicated for adults with obesity (BMI ≥ 30 kg/m²), or adults who are overweight (BMI ≥ 27 kg/m²) and also have at least one weight-related medical problem such as hypertension, dyslipidemia, obstructive sleep apnea, or cardiovascular disease, to reduce excess body weight and maintain weight reduction long term. It should be used alongside a reduced-calorie diet and increased physical activity.
How does Orforglipron work?
Orforglipron works by activating GLP-1 (glucagon-like peptide-1) receptors in the body. As a once-daily oral small molecule GLP-1 receptor agonist, it mimics the action of the naturally occurring incretin hormone GLP-1, which is released after eating. By activating GLP-1 receptors, Orforglipron helps reduce appetite and food intake, slows stomach emptying, and promotes a feeling of fullness, all of which contribute to weight loss over time. Unlike peptide-based GLP-1 drugs (such as injectable semaglutide or tirzepatide), Orforglipron is a non-peptide small molecule that is fully absorbed orally without requiring fasting or specific fluid restrictions.
How do I take Orforglipron?
Orforglipron is taken by mouth once a day, at any time of day, with or without food — there are no food or water restrictions. Swallow tablets whole; do not break, crush, or chew them. Take exactly as directed by your healthcare provider. If you miss a dose, take it as soon as possible, but do not take 2 doses in the same day. If you miss 7 or more consecutive days, contact your healthcare provider before restarting. Treatment should always be combined with a reduced-calorie diet and increased physical activity.
Is it safe for me to take Orforglipron?
Orforglipron is a safe and effective treatment when used for its FDA-approved indication. However, like all medications, it may cause unwanted side effects. Always discuss potential side effects with your physician to ensure the medication is suitable for you.
