Compounded semaglutide is not FDA-approved Trusted sourceU.S. Food and Drug AdministrationFederal regulatory agency for food and health-related productsGo to source , so its safety and effectiveness are not evaluated by the FDA.

The primary difference between compounded semaglutide and Ozempic is how they are made and regulated.

• Ozempic is a brand-name, FDA-approved prescription drug, which means it has been tested for safety and effectiveness Trusted sourcePubMed Central (PMC)PubMed Central is the National Library of Medicine's free full-text archive of biomedical and life sciences journal literatureGo to source .

• Compounded semaglutide is made by individual pharmacies and filled according to a healthcare professional’s prescription. It does not have the same strict quality controls as Ozempic, so it could vary in strength and reliability, depending on which compounding pharmacy you buy from.

Is semaglutide a generic for Ozempic?

No, there is no FDA-approved generic version Trusted sourceU.S. Food and Drug AdministrationFederal regulatory agency for food and health-related productsGo to source of Ozempic.

1. Ozempic is a subcutaneous injection for type 2 diabetes. It can also be prescribed off-label for weight loss.

2. Wegovy is another once-weekly injection but has a higher dose of semaglutide (2.4 mg weekly). It’s FDA-approved for weight loss in people with obesity or overweight and have a weight-related health issue, like type 2 diabetes or high blood pressure.

3. Rybelsus is an oral form of semaglutide. It is FDA-approved for controlling blood sugar in type 2 diabetes.

Is compounded semaglutide as effective as Ozempic?

The effectiveness can vary by compounding pharmacy. One of the main differences is that compounded semaglutide is custom-made to fit a person’s specific needs, such as different strengths or ingredients, which can help if someone has allergies to a particular ingredient in the brand name drug.

Compounded semaglutide can be a good option for people who can’t take the brand-name Ozempic for medical reasons such as an allergy to a specific ingredient. Some pharmacies also make it to help patients during shortages, so they can still get their medication.

Ozempic drug shortage

There was recently a shortage of FDA-approved semaglutide injections including Ozempic, which meant it was harder for some people to get the medication. This shortage has been caused by high demand and production delays.

If you can’t use Ozempic for medical reasons, you might consider compounded semaglutide. Speak with your doctor or pharmacist about whether compounded semaglutide is right for you.

Is compounded semaglutide safe?

Yes, compounded semaglutide can be safe, but it’s not FDA-approved, so it’s less regulated than brand-name medications like Ozempic. This means the quality and strength might vary.

The FDA has issued warnings Trusted sourceU.S. Food and Drug AdministrationFederal regulatory agency for food and health-related productsGo to source for semaglutide, that some compounded semaglutide may contain salt forms of semaglutide, like semaglutide sodium or semaglutide acetate, instead of the base form found in FDA-approved drugs like Ozempic.

When semaglutide is compounded as a salt Trusted sourceU.S. Food and Drug AdministrationFederal regulatory agency for food and health-related productsGo to source , it can affect its safety and efficacy and may lead to dosing errors or diminished efficacy.

There is no evidence to prove that these salt forms are safe or effective, and compounded semaglutide with these salts may not meet federal safety standards.

The high demand and cost of brand-name semaglutide products might lead people to use compounded versions. However, the company that makes Ozempic, Novo Nordisk, does not sell semaglutide for compounding, raising concerns about where compounded semaglutide comes from and the possible use of different formulas. Always use a reputable and state-licensed compounding pharmacy that adheres to strict state and federal guidelines.

What is the difference between Ozempic and compounded semaglutide?

The key difference between compounded drugs and FDA-approved versions is that compounded drugs are not FDA-approved.

Compounded semaglutide is a custom-made version of the approved medication, often to accommodate a patient’s needs or during shortages. Compounded semaglutide is not FDA-approved for weight loss or any other use.

Compounded semaglutide is not standardized, meaning its quality and safety can vary, and it hasn’t been tested in clinical trials. Some pharmacies might use semaglutide salts, which are not the same as the semaglutide used in Ozempic. Always check with the compounding pharmacy to ensure you are not receiving the sale form of semaglutide.

Ozempic is made by Novo Nordisk, the only company approved by the FDA to produce medications with semaglutide, including Ozempic, Wegovy, and Rybelsus. Compounded semaglutide is not identical to Ozempic, as it’s not made by the same company or regulated in the same way.

Dosage and administration

Ozempic comes in injectable pens, with each pen containing 4 to 8 doses. You need to attach a new needle for each injection. Compounded semaglutide usually comes in small glass vials, and you’ll use a syringe to draw your dose for each injection.

For Ozempic, the starting dose is 0.25 mg, injected once a week. After 4 weeks, the dose is increased to 0.5 mg per week. The recommended maximum dose is 2 mg per week.

The dosage schedule for compounded semaglutide can vary by pharmacy.

With Ozempic, people usually start seeing weight loss and improved blood sugar control within a few weeks. It can take up to 3-6 months to see the full benefits. For compounded semaglutide, the time to see results may vary, depending on the formulation and individual response, but there’s no official data on its timeline.

Comparison of severity and frequency of side effects between semaglutide and Ozempic

• The most common side effect of Ozempic is nausea, which affects about 15% to 20% of people. Other side effects include vomiting (5% to 9%), diarrhea (8%), stomach pain (6% to 7%), and constipation (3% to 7%).

Long-term safety considerations

Ozempic has been studied for long-term safety, and it’s considered safe for most people when used as directed. Compounded semaglutide lacks extensive long-term safety data because it’s not FDA-approved. Therefore, its long-term safety is uncertain and may vary depending on the compounding process by the compounding pharmacy you purchase from.

Cost

Branded Ozempic is expensive, often costing around $1,000 or more for a month’s supply. Compounded semaglutide pricing can vary depending on the pharmacy and location.

Ozempic may be covered by insurance, but coverage can vary. Novo Nordisk offers savings programs to help reduce the cost for eligible patients, which can significantly lower the price for some people. There is no savings card program available for compounded semaglutide.

To make Ozempic more affordable, check if your insurance covers it and ask about savings programs. You can also compare prices at different pharmacies or look for discount cards online. For compounded semaglutide without insurance, shop around at different semaglutide compounding pharmacies to find the best price.

Bottom line

Ozempic is an effective, FDA-approved treatment for controlling blood sugar control and weight loss (off-label). Compounded semaglutide may work similarly as it contains the same active ingredient as the brand name drug, but without the testing and regulation of the FDA (U.S. Food and Drug Administration).

Ozempic is manufactured under strict regulations. Compounded semaglutide is made by compounding pharmacies and can vary in strength which can affect safety and efficacy, depending on the compounding pharmacy you purchase from.

Compounded semaglutide is a solution for those who can’t get FDA-approved semaglutide due to shortages or for patients who require customized dosing. It can be customized to your needs with the guidance of a healthcare provider.

Both drugs can help people lose between 15% to 20% of their body weight when combined with a healthy diet and exercise. Before choosing to start a new medication, discuss your health goals, insurance coverage, and any potential side effects with your healthcare provider to find the most effective and safe treatment.
