Is compounded semaglutide the same as Ozempic?
Semaglutide is a medicine that helps lower blood sugar. It belongs to a group of diabetes medicines known as glucagon-like peptide-1 receptor agonists that help release insulin when blood sugar is high. Semaglutide is available in FDA-approved diabetes and weight-management drugs including the following:
Ozempic® is an FDA-approved semaglutide injection given once a week. It’s approved to improve blood sugar control in adults with type 2 diabetes as an addition to diet and exercise. Ozempic is also approved to reduce the risk of major cardiovascular events, such as heart attack or stroke, in adults with type 2 diabetes who have established cardiovascular disease. Ozempic is also approved to reduce kidney-related risks in adults with type 2 diabetes and chronic kidney disease.
While not specifically approved for weight management, Ozempic may be prescribed for weight management off-label. Wegovy® is an FDA-approved semaglutide drug with a weight-management indication.
Ozempic is available as a prefilled pen that includes specific instructions for use. Compounded semaglutide, on the other hand, may come in multidose vials with a variety of concentrations or be combined with other ingredients like vitamin B12. The salt forms sold by some compounders raise separate concerns, discussed below.
What are the risks of compounded semaglutide?
Medications compounded at a local or other pharmacy aren't FDA-approved like Ozempic and Wegovy. This means they haven't been reviewed by FDA to make sure the medicines are safe and effective. Compounded semaglutide does not inherit the clinical trial evidence for Ozempic or Wegovy.
What to check before using compounded semaglutide
Check if compounded semaglutide is appropriate for you. Discuss your health history with your prescriber, including past or current digestive problems and pregnancy plans.
Verify who's making compounded semaglutide. Check who is prescribing it, which pharmacy is compounding it, the pharmacy’s address and license, and where it’s being shipped. Many times the pharmacy that dispenses a GLP-1 drug is different from the telehealth platform that offers the treatment.
Confirm you have easy access to your prescriber and dispensing pharmacy. Make sure you know how to reach out to your prescriber and pharmacy with any questions.
Be careful if compounded semaglutide shipments aren't cold. FDA advises consumers to avoid using an injectable GLP-1 drug if the product isn’t adequately refrigerated, including if your medication arrives at your home warm.
FDA advises patients to discard multidose vials of compounded GLP-1 drugs within 28 days of opening (first use). Do this even if your compounder instructs that it’s okay to keep using it for a longer time frame.
Understand your compounded semaglutide dose. FDA has received reports of serious medication dosing errors with compounded injectable semaglutide products that have led to hospitalization. This has been due to confusion about dosing units, such as mixing up units on the syringe, milliliters, and milligrams, especially since compounded semaglutide is prepared at different strengths/concentrations in the vial. Ask the pharmacist to show you how your prescription, vial concentration, and supplied syringe fit together before injecting.
FDA’s semaglutide compounding warning
FDA warned that compounded semaglutide drugs as salts, such as semaglutide sodium or semaglutide acetate, aren't the same as the FDA-approved injectable semaglutide medications Ozempic or Wegovy. Semaglutide sodium and semaglutide acetate have no known lawful basis for compounding and are different active ingredients from the semaglutide used in FDA-approved drugs.
Additionally, FDA says the safety and effectiveness of combining semaglutide with other ingredients, including vitamin B12, have not been established. Adding B12 has not been shown to make the medicine safer, work better or cause fewer side effects.
Compounding rules after FDA declared the semaglutide shortage over
FDA declared the national semaglutide injection shortage resolved on February 21, 2025. The shortage-related transition periods for compounders have since ended. In April 2026, FDA reiterated that compounding drugs that are essentially copies of commercially available semaglutide products is restricted. A local pharmacy’s Ozempic stockout does not put semaglutide back on the national shortage list.
Note that a drug being compounded by a pharmacy doesn't mean the drug is FDA-approved:
A state-licensed pharmacy operating under section 503A can do patient-specific compounding when the applicable conditions are met. With semaglutide, this means your prescriber would need to determine and document that a change produces a significant difference for you compared with an available approved drug, based on your specific health situation.
An FDA-registered section 503B outsourcing facility can do some types of compounding for multiple patients, subject to legal conditions. That status alone does not authorize compounding semaglutide from bulk ingredients.
Is compounded semaglutide less expensive?
A lower advertised monthly price does not necessarily mean lower total treatment costs. What you pay depends on the medication, your coverage and the service’s fees. Make sure to understand the full cost of GLP-1 treatment before you get started, including:
Monthly medication costs: Many telehealth services advertise low-cost compounded semaglutide, but there may be higher-priced dosage tiers that could be recommended after you get started. Understand the full costs for compounded vs. name-brand semaglutide and other GLP-1 drugs.
Telehealth plan or membership costs: Check any monthly or yearly costs to receive compounded semaglutide at a telehealth service.
Clinician visit costs: Some services charge for office visits, telehealth visits or medication management. Make sure you understand if and when you’ll be charged to see a clinician at your GLP-1 service.
Medication refills: Check how you’ll be charged when you get compounded semaglutide medication refills.
Shipping and storage costs: Check whether refrigerated delivery costs extra and what storage arrangements you’ll need at home.
Medication supplies: Understand what’s needed to use your compounded semaglutide vial, including syringes, alcohol swabs and a sharps container. Ask whether these supplies are included in the quoted price.
Lab tests and monitoring costs: Ask if and when you’ll be asked to pay for lab work with semaglutide treatment.
Other treatment costs: For example, if you’re on another medication that needs to be adjusted when you start compounded semaglutide, make sure you understand costs for a new prescription.
