What Is Ozempic?
Last reviewed: May 2026 · Haute MD Editorial Team
Ozempic is the brand name for semaglutide, a once-weekly injectable GLP-1 receptor agonist made by Novo Nordisk and FDA-approved to treat type 2 diabetes and reduce cardiovascular risk in adults with type 2 diabetes and known heart disease. It is widely prescribed off-label for weight loss, though the same molecule is FDA-approved specifically for weight management under the brand name Wegovy, at higher doses.
How Ozempic works
Semaglutide mimics the body's natural GLP-1 hormone, which is released by the gut after meals. It binds GLP-1 receptors in the pancreas (boosting glucose-dependent insulin release and suppressing glucagon), the brain (reducing appetite and food reward signaling), and the gut (slowing gastric emptying so food stays in the stomach longer). The combined effect lowers blood sugar, reduces hunger, and increases satiety, leading to lower food intake and meaningful weight loss as a downstream effect.
FDA-approved uses and dosing
Ozempic is FDA-approved for adults with type 2 diabetes to improve glycemic control alongside diet and exercise, and to reduce major cardiovascular events in type 2 diabetes patients with established cardiovascular disease. It is also approved to reduce risk of progression of chronic kidney disease. Doses are 0.25 mg weekly (starting), titrated to 0.5, 1.0, and 2.0 mg weekly. The same molecule for weight loss is sold as Wegovy at doses up to 2.4 mg weekly.
What to expect — benefits and side effects
Patients typically lose 10-15% of body weight on semaglutide over 12-18 months, with HbA1c reductions of 1.5-2% in diabetic patients. The most common side effects are gastrointestinal — nausea, vomiting, constipation, diarrhea — and are usually mild and improve over time. Less common but more serious risks include pancreatitis, gallbladder disease, and a boxed warning for thyroid C-cell tumors based on rodent data (not confirmed in humans). It is contraindicated in personal or family history of medullary thyroid carcinoma or MEN2 syndrome.
Frequently Asked Questions
Is Ozempic the same as Wegovy?
Both are semaglutide made by Novo Nordisk. Ozempic is approved for type 2 diabetes at doses up to 2.0 mg weekly. Wegovy is approved for chronic weight management at doses up to 2.4 mg weekly. The molecule, mechanism, and side effect profile are the same.
Can I take Ozempic if I don't have diabetes?
Many physicians prescribe Ozempic off-label for weight loss, but the on-label, insurance-approved option for non-diabetic weight management is Wegovy. Both contain the same drug.
How long do you have to stay on Ozempic?
Obesity is a chronic disease. Most patients who stop semaglutide regain a significant portion of the lost weight within 1-2 years because the underlying biology returns. Most obesity specialists frame GLP-1 therapy as long-term, similar to blood pressure or cholesterol medication.
Will my insurance cover Ozempic?
Insurance typically covers Ozempic for type 2 diabetes. Coverage for weight loss specifically (Wegovy, Zepbound) varies widely and is improving but still limited. A longevity or obesity-medicine physician can navigate prior authorization and alternatives.

How Do GLP-1 Medications Work?
GLP-1 medications mimic a gut hormone that suppresses appetite, slows gastric emptying, and improves insulin response — leading to lower blood sugar and significant weight loss.
