Side-by-side comparison
| Dulaglutide | Exenatide | |
|---|---|---|
| Category | Weight Management & Metabolic | Weight Management & Metabolic |
| Regulatory status (US) | FDA approved | FDA approved |
| Typical dosage | 0.75-4.5 mg | 5–10 mcg (Byetta) or 2 mg (Bydureon/Bydureon BCise) |
| Frequency | weekly | Twice daily (Byetta) or once weekly (Bydureon) |
| Reported benefits | Blood sugar control, weight management, cardiovascular benefits | Glycemic control (HbA1c reduction 0.8–1.9 percentage points), modest body weight reduction (2–4 kg), low intrinsic hypoglycemia risk, modest systolic blood pressure reduction, cardiovascular non-inferiority established in EXSCEL |
| Reported side effects | Nausea, diarrhea, injection site reactions | Nausea, vomiting, diarrhea, injection site reactions, hypoglycemia (when co-administered with sulfonylureas), rare acute pancreatitis, rare acute kidney injury |
Key differences
Primary use. Dulaglutide is categorised under Weight Management & Metabolic, while Exenatide falls under Weight Management & Metabolic. Because they target a similar goal, they are common alternatives to weigh against each other.
Regulatory status. Dulaglutide: FDA-approved. Exenatide: FDA-approved.
Dosing. Dulaglutide is typically dosed at 0.75-4.5 mg (weekly). Exenatide is typically dosed at 5–10 mcg (Byetta) or 2 mg (Bydureon/Bydureon BCise) (Twice daily (Byetta) or once weekly (Bydureon)).
Can you stack them?
Some protocols combine peptides, but stacking Dulaglutide and Exenatide has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
