Both semaglutide and liraglutide cause gastrointestinal adverse effects (nausea, vomiting, diarrhea) which are the most common reason for drug discontinuation.
Expect gastrointestinal side effects like nausea when starting GLP-1 medications. These are common, usually mild, and tend to decrease over time. Slow titration can help manage them.
GoodSupportsHIGH confidence
Gastrointestinal (GI) adverse effects represent the most common adverse events that characterize all GLP-1 RAs... GI adverse effects were the most frequent cause of premature drug withdrawal.

- Once-weekly semaglutide 2.4 mg produces significantly greater weight loss than once-daily liraglutide 3.0 mg in patients with obesity, based on indirect comparisons of randomized controlled trials.Moderate
- Semaglutide and liraglutide have similar anti-hyperglycemic efficacy, with no consistent significant difference in HbA1c reduction between the two drugs.Moderate

- 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
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
