Semaglutide for Medical Weight Loss
Semaglutide is a GLP-1 receptor agonist available in products with different FDA-approved indications. Brand, formulation and indication should not be treated as interchangeable.
How it is used in weight management
Wegovy formulations are indicated for chronic weight management in eligible patients alongside reduced-calorie nutrition and physical activity. Treatment generally begins at a low dose and is adjusted according to the applicable label, tolerance and clinical judgment.
Wegovy injection and Wegovy tablets differ in administration. Ozempic and Rybelsus are semaglutide products associated with diabetes indications and should not be presented as identical weight-loss brands.

Safety and follow-up
Common problems include nausea, vomiting, diarrhea, constipation and abdominal symptoms. Important warnings and precautions include thyroid C-cell tumor risk, pancreatitis, gallbladder disease, kidney injury related to dehydration, severe gastrointestinal reactions, diabetic retinopathy complications in some patients and hypoglycemia with certain diabetes drugs. Do not combine with another semaglutide-containing product or GLP-1 receptor agonist.
