Wegovy vs. Rybelsus

Wegovy and Rybelsus are both semaglutide-based drugs, but their administration methods and approvals differ significantly. Wegovy is an injectable GLP-1 receptor agonist for chronic weight management, while Rybelsus is an oral formulation for type 2 diabetes. Wegovy delivers more pronounced weight loss (15% bodyweight) compared to Rybelsus’s HbA1c reductions and moderate weight effects. Wegovy has no off-label uses, whereas Rybelsus is occasionally used off-label for weight management. Common side effects of both drugs include nausea, but Rybelsus may pose higher risks of gastrointestinal discomfort. Wegovy is far more expensive, averaging $1,375/month, compared to Rybelsus’s $875/month. Neither drug currently faces shortages.
