Safety is the most important consideration when starting any medication. GLP-1 medications have been extensively studied in clinical trials involving tens of thousands of patients, and they have a well-established safety profile when prescribed and monitored by licensed healthcare providers.
What the Research Shows
The STEP and SURMOUNT clinical trial programs included over 25,000 participants combined. These large-scale studies established the efficacy and safety profile that led to FDA approval for weight management.
