When I first heard about semaglutide, I was surprised by how many brand names it goes by. From Ozempic® to Wegovy® and a few others, each one has its own unique purpose and benefits. With so much buzz around these medications, it’s easy to get confused about which brand does what.

I know how important it is to understand your options, especially when it comes to health. That’s why I want to break down the different semaglutide brands and what sets them apart. Whether you’re curious about weight loss solutions or managing diabetes, knowing the brand names can help you make more informed decisions.

What Is Semaglutide?

Semaglutide is a GLP-1 receptor agonist that mimics the incretin hormone GLP-1 to regulate blood sugar. Doctors prescribe semaglutide for adults with type 2 diabetes or obesity. Researchers at Novo Nordisk first developed semaglutide, introducing it for clinical use in 2017.

Injectable semaglutide, available as subcutaneous formulations, reduces glycated hemoglobin (HbA1c) and body weight. It stimulates insulin secretion, decreases glucagon levels, and slows gastric emptying. These actions lower blood glucose and promote satiety.

The FDA has approved semaglutide for type 2 diabetes and chronic weight management. Brand names include Ozempic® for diabetes, Wegovy® for obesity, and Rybelsus® as an oral tablet. Trials, such as SUSTAIN and STEP, support its efficacy and safety for these indications.

Doctors monitor patients for adverse reactions such as nausea, vomiting, and pancreatitis. Higher doses may result in increased gastrointestinal side effects. Semaglutide use remains contraindicated in patients with medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.

How Semaglutide Works

Semaglutide works by activating the GLP-1 receptor, a protein found on pancreatic beta cells that responds to glucagon-like peptide-1. I see semaglutide mimics natural GLP-1 hormone action so it raises insulin secretion when blood glucose is high. This lowers glucose in the bloodstream after meals.

Semaglutide reduces the hormone glucagon’s secretion, which suppresses the liver’s glucose release. This dual action improves blood sugar control in type 2 diabetes.

Semaglutide also delays gastric emptying, so food exits the stomach more slowly. I find this effect leads to increased satiety, which reduces food intake and supports weight loss—key for obesity management underscored by evidence in the STEP clinical trial series (Wilding et al., 2021, NEJM).

I monitor for semaglutide’s effects on appetite centers in the brain. Activation of GLP-1 receptors modulates hunger cues so patients experience less frequent and less intense hunger.

Semaglutide doesn’t typically cause hypoglycemia when used alone, though the risk increases if combined with insulin or sulfonylureas. I always check for possible interactions and adjust treatments as needed to optimize therapy results.

Approved Semaglutide Brand Names

Three semaglutide brand names hold FDA approval in the US for diabetes and obesity treatment. I compare common indications and characteristics under each name below.

Ozempic®

Ozempic® contains injectable semaglutide formulated for adults with type 2 diabetes. I see Ozempic® dosed once weekly, with strengths including 0.25 mg, 0.5 mg, 1 mg, and 2 mg per injection (Novo Nordisk, FDA). Most patients use Ozempic® to lower A1C and reduce cardiovascular risk in diabetic populations when paired with diet and exercise. Ozempic® is not indicated for weight loss alone.

Wegovy®

Wegovy® delivers semaglutide for chronic weight management. I find doses of Wegovy® at 2.4 mg once weekly, which is the highest approved semaglutide strength for any indication (FDA, 2021). Wegovy® targets adults with obesity (BMI ≥30) or overweight (BMI ≥27) with at least one weight-related comorbidity, such as hypertension, hyperlipidemia, or type 2 diabetes. Wegovy® therapy is used alongside reduced-calorie meal plans and increased physical activity.

Rybelsus®

Rybelsus® is the only oral semaglutide brand approved for type 2 diabetes. Rybelsus® offers tablets in 3 mg, 7 mg, and 14 mg strengths taken once daily. Most prescriptions of Rybelsus® help reduce A1C when diet and exercise alone provide insufficient glycemic control. Rybelsus® does not hold approval for weight loss or obesity treatment.

Off-Label and International Semaglutide Brands

Several semaglutide brands exist beyond FDA-approved Ozempic®, Wegovy®, and Rybelsus®, especially in international markets and off-label compounding.

• International semaglutide brands:

I find semaglutide brands like Rybelus® (India), Wegovy® (Europe, Canada), and Ozempic® (worldwide) present with different packaging, device appearance, or local branding, depending on regulatory approval and country-specific supply chains.

• Compounded semaglutide for off-label use:

I see compounded versions prepared in US compounding pharmacies for off-label weight loss, frequently when the FDA-approved Wegovy® faces shortages. These formulations sometimes use semaglutide sodium salt, a form not identical to branded products, which the FDA has warned may not ensure similar safety or effectiveness (FDA, Drug Shortages Q&A, December 2023).

• Other international names and biosimilars:

I note emerging examples in clinical registries and pharmaceutical catalogs, such as Ozempic Pen (Australia), Ozempic FlexTouch® (EU), and biosimilar products in early development or pending approval in Asia and Eastern Europe, creating a complex global brand landscape.

• Legal and regulatory constraints:

I observe that some international or compounded versions use non-FDA-approved excipients or delivery methods, raising quality concerns. Regulatory frameworks, such as those in the EU or Brazil (Anvisa), only permit semaglutide distribution through approved channels.

These off-label and international options generally appear in contexts where branded semaglutide is rare or too costly.

Key Differences Between Semaglutide Brands

Semaglutide brands differ in approved uses, dosing schedules, and how patients receive the drug. I see clear distinctions in clinical intent and convenience among these options.

Uses and Indications

Ozempic® specifically targets adults with type 2 diabetes to improve glycemic control and lower major cardiovascular risk. Wegovy® focuses on chronic weight management in adults with obesity (BMI ≥30) or overweight individuals (BMI ≥27) with at least one weight-related health issue, such as hypertension or dyslipidemia. Rybelsus® is indicated for type 2 diabetes management, but not for weight loss. Compounded semaglutide formulations may be used off-label for weight loss, but major professional societies and the FDA don’t endorse this use due to safety and efficacy uncertainties.

Dosage Forms and Administration

Ozempic® and Wegovy® are available as once-weekly injectable pens, but their maximum indicated doses differ: Ozempic® is titrated up to 2 mg weekly for diabetes, while Wegovy® reaches 2.4 mg weekly for weight loss. Rybelsus® is unique as a daily oral tablet, available in 7 mg and 14 mg doses, enhancing access for type 2 diabetes patients who prefer not to inject. Compounded semaglutide is usually injectable and may be offered in alternative strengths, though these don’t follow standardized dosing and delivery protocols approved for branded products.

How to Choose the Right Semaglutide Brand

Selecting the right semaglutide brand depends on clinical needs and individual preferences, with FDA-approved options including Ozempic®, Wegovy®, and Rybelsus®.

• Review Indications: Ozempic® treats type 2 diabetes and lowers cardiovascular risk, Wegovy® addresses chronic weight management, and Rybelsus® helps with glycemic control in type 2 diabetes. Off-label and compounded versions arise in shortages or when cost prohibits branded access.
• Compare Administration Methods: Ozempic® and Wegovy® require subcutaneous weekly injections, while Rybelsus® comes as a daily oral pill. Compounded semaglutide may use alternate delivery routes, increasing variability. I check each patient’s preference and comfort with injections or pills.
• Evaluate Dosing Schedules: Ozempic® and Wegovy® use different maximum doses and titration plans for their specific indications, while Rybelsus® dosing remains fixed for glycemic control. Dosing frequency impacts adherence, especially for those with busy schedules.
• Consider Safety and Purity: FDA-approved brands guarantee strict safety, consistency, and efficacy, while compounded versions pose potential risks due to lack of federal regulation or thorough testing. I weigh therapeutic benefit against adverse event risk after confirming regulatory status.
• Factor in Cost and Availability: Brand-name options may cost more, but insurance coverage often influences total out-of-pocket expense. Compounded or international products offer lower prices, but typically lack insurance support and official oversight. I advise considering insurance coverage and local availability before choosing.
• Assess Comorbidities and Contraindications: Thyroid conditions, pancreatitis history, and medication allergies affect eligibility for all semaglutide forms. I review medical history thoroughly before deciding among options.

Physician input and regulatory guidance inform each decision. Consistent brand supply, clear FDA approval status, and medical appropriateness guide final selection for diabetes or obesity management.
