Semaglutide demonstrates superior efficacy compared to Liraglutide in reducing hemoglobin A1c (HbA1c) levels, though it shows no significant difference in weight loss or fasting blood sugar (FBS) reduction compared to Liraglutide.
If you are managing Type 2 Diabetes without metformin, switching from Liraglutide to Semaglutide is likely to improve your blood sugar control (HbA1c) more effectively. However, do not expect significantly more weight loss from this switch alone, as both drugs appear to offer similar weight reduction benefits.
Semaglutide significantly reduced hemoglobin A1c (HbA1c) levels compared to Liraglutide (0.56; 95% CI: 0.19–0.94; p < 0.001). However, no significant differences were observed between Semaglutide and Liraglutide in terms of fasting blood sugar (FBS), body mass index (BMI), and weight change.
Why this rating
Based on a systematic review and meta-analysis of 16 studies involving 5,997 patients, including RCTs.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
