Who makes semaglutide? Novo Nordisk manufactures Ozempic, Wegovy, and Rybelsus. Learn about generics, compounded versions, and safety in the US.
Novo Nordisk makes semaglutide. The Danish pharmaceutical company is the only manufacturer with FDA approval to sell semaglutide in the United States, where it markets the drug as Ozempic, Wegovy, and Rybelsus. No generic version of semaglutide is approved for sale in the U.S. as of 2026.
Novo Nordisk: The Company Behind Semaglutide
Novo Nordisk is a global healthcare company headquartered in Bagsværd, Denmark. It was founded in 1923 and has become a leader in diabetes and obesity care. The company discovered semaglutide and holds the patents that prevent other manufacturers from selling generic copies in the United States.
When people search for semaglutide Novo Nordisk, they are looking for the same manufacturer. Novo Nordisk controls the entire supply chain for its branded semaglutide products, from the active pharmaceutical ingredient to the finished pen or tablet.
Novo Nordisk also manufactures other diabetes and obesity medications, including liraglutide (Victoza, Saxenda) and insulin products. However, semaglutide remains its most well-known and profitable drug.
Novo Nordisk is the sole FDA-approved manufacturer of semaglutide in the United States.
Brand Names Made by Novo Nordisk
Novo Nordisk sells semaglutide under three brand names in the U.S. Each product uses the same active ingredient but is approved for different uses and comes in different forms.
| Brand Name | Form | Primary Use | Manufacturer |
|---|---|---|---|
| Ozempic | Injectable pen | Type 2 diabetes | Novo Nordisk |
| Wegovy | Injectable pen | Chronic weight management | Novo Nordisk |
| Rybelsus | Oral tablet | Type 2 diabetes | Novo Nordisk |
The Wegovy manufacturer is also Novo Nordisk. Wegovy was approved by the FDA in 2021 for chronic weight management in adults with obesity or overweight with at least one weight-related condition.
All three FDA-approved semaglutide brands are manufactured by Novo Nordisk.
Is There a Generic Semaglutide?
No generic semaglutide is available in the United States. Novo Nordisk's patents on semaglutide do not expire until the early 2030s, which blocks competitors from making generic copies.
Outside the U.S., the situation is changing. In Canada, Novo Nordisk's patent expired in January 2026, and generic manufacturers have started to launch their own versions. Other countries may follow as patents expire.
Patent litigation is common in the pharmaceutical industry. Novo Nordisk has successfully defended its semaglutide patents against multiple challengers, including generic drugmakers seeking to launch their own versions before expiration.
Generic semaglutide is not legally available in the U.S. because Novo Nordisk's patents remain in force.
Compounded Semaglutide: Who Makes It?
Compounded semaglutide is made by state-licensed compounding pharmacies and 503B outsourcing facilities. These products are not FDA-approved and are not manufactured by Novo Nordisk.
During a semaglutide shortage that began in 2022, the FDA allowed compounding pharmacies to make copies. The FDA declared the shortage resolved in 2024 and 2025, so compounded semaglutide is now only permitted in limited circumstances.
Compounded semaglutide may contain semaglutide salts or other forms not found in FDA-approved products. The FDA has warned that these differences can lead to dosing errors and other safety risks.
Compounded semaglutide is not manufactured by Novo Nordisk and is not FDA-approved.
How to Verify Who Made Your Semaglutide
If you want to confirm the manufacturer of your semaglutide, check the following:
- Look for the Novo Nordisk logo and the brand name (Ozempic, Wegovy, or Rybelsus) on the packaging.
- Find the National Drug Code (NDC) on the label and verify it with the FDA's database.
- Be cautious of websites selling 'generic semaglutide' or 'research grade' semaglutide.
- Ask your pharmacist to confirm the manufacturer and the source of the product.
You can also check the lot number and expiration date on the pen or tablet. If the packaging lacks these details, the product may be counterfeit or compounded.
Legitimate semaglutide products in the U.S. are made by Novo Nordisk and carry the company's branding.
Safety, Side Effects, and What to Know
Semaglutide can cause side effects, most commonly nausea, vomiting, diarrhea, and constipation. Talk to your healthcare provider about semaglutide side effects and whether the medication is right for you.
Some users report that semaglutide makes me tired, which can affect daily activities. Fatigue is not listed as a common side effect in clinical trials, but individual experiences vary.
Researchers are also studying combination therapies. Clinical trials are testing cagrilintide and semaglutide together for obesity, and some early research looks at aod 9604 and semaglutide for fat loss.
Stacking retatrutide and semaglutide is not recommended and has not been evaluated in human trials. Always consult a healthcare professional before combining any medications.
Before starting semaglutide, tell your doctor about any history of pancreatitis, gallbladder disease, or kidney problems. Semaglutide is not recommended during pregnancy.
Semaglutide is a prescription medication, and you should only use it under the supervision of a licensed healthcare provider.
