Ozempic vs Other GLP-1 Medications Understanding the differences, uses, and considerations
What Are GLP-1 Medications? GLP-1 (glucagon-like peptide-1) is a hormone naturally produced by the small intestine after you eat. GLP-1 receptor agonist medications mimic this hormone and activate GLP-1 receptors to help regulate blood sugar, digestion, and appetite.

⚖️Slower Digestion These medications also suppress glucagon secretion, which would otherwise raise blood sugar, and slow gastric emptying so food leaves the stomach more gradually.
SPOTLIGHT
Ozempic: What Is It? Ozempic is a once-weekly injectable medication containing semaglutide, a GLP-1 receptor agonist. It was developed and FDA-approved specifically for Type 2 diabetes management, though it has gained widespread attention for its weight-related effects.

Targets two receptors vs. semaglutide's one, producing greater average weight loss.
Weight Loss: Head-to-Head Data Clinical trials reveal a meaningful gap in average weight reduction between the two molecules.
What the Trials Show Semaglutide 2.4 mg (Wegovy) produced an average 14.9% weight reduction at 68 weeks in the STEP 1 trial, published in NEJM (2021). SUSTAIN 7 showed that semaglutide 1.0 mg reduced body weight by 6.5 kg versus 3.0 kg with dulaglutide 1.5 mg in a peer-reviewed head-to-head trial.
These results come from peer-reviewed clinical trials: STEP 1 and SUSTAIN 7.
Side Effects: What to Expect Both drug classes share a similar side-effect profile, dominated by gastrointestinal effects — especially during dose escalation.
Most Common (Both) Nausea, vomiting, diarrhea, constipation, and fatigue — typically most pronounced during the first weeks of treatment
Semaglutide-Specific Retinopathy precaution for diabetic patients; monitor closely if pre-existing eye conditions are present
Boxed Warning (Both) Thyroid C-cell tumors (in rodent studies), pancreatitis risk, and gallbladder disease — discuss full risk profile with your physician
