Is compounded semaglutide safe? What to know before you start

Compounded semaglutide is not FDA-approved, so no compounded version has been reviewed by FDA for safety, effectiveness or quality before it is dispensed. That does not make every compounded product unsafe, but the protections that come with an approved medicine do not apply in the same way. Most of the risks you can control come down to three questions: who prepares it, what exactly is in the vial and how the dose is measured. FDA on compounded drugs.

What is compounded semaglutide?

Compounding is when a pharmacy prepares a medicine for an individual patient based on a prescription. Semaglutide is a GLP-1 receptor agonist: it acts like a hormone the body releases after eating, which affects appetite, how quickly the stomach empties and blood sugar. Semaglutide injection information.

FDA-approved semaglutide medicines include Ozempic, approved for type 2 diabetes, and Wegovy, approved for chronic weight management. Compounded semaglutide is a separate product prepared by a compounding pharmacy. It is not a generic version of either medicine, and FDA has warned companies not to describe compounded drugs as generic or as the same as an approved drug. FDA guidance for telehealth companies.

How is it different from Ozempic and Wegovy?

	Ozempic and Wegovy injections	Compounded semaglutide
FDA review before sale	Yes: safety, effectiveness and manufacturing quality	No
Clinical trials of the product itself	Yes	No published trials of compounded formulations
Usual form	Prefilled pen with set doses	Often a multi-dose vial drawn up with a syringe
Ingredients	Approved formula	Set by the pharmacy; may include an added ingredient such as glycine, niacinamide or a vitamin
Who makes it	Manufacturer, under the FDA approval	State-licensed compounding pharmacy or registered outsourcing facility

The form matters in practice. With a pen, the dose is set by the device. With a vial, you measure each dose yourself, which is where FDA has seen serious errors.

Do Wegovy results apply to compounded semaglutide?

No. The STEP clinical trials that support Wegovy’s approval tested Wegovy itself, at specific doses, together with diet and exercise. Those results describe that product. No comparable trials have been published for compounded semaglutide, so its results cannot be assumed to match. STEP 1 trial.

• Adverse event reports. As of May 31, 2026, FDA had received 990 reports of adverse events associated with compounded semaglutide. A report shows that a problem was reported, not that the medicine caused it.
• Dosing errors. FDA has described patients who injected 5 to 20 times the intended dose after confusing milliliters, milligrams and syringe “units”. Some needed hospital care. FDA dosing error alert.
• Salt forms. Semaglutide sodium and semaglutide acetate are different active ingredients from the one used in the approved medicines. FDA says it knows of no lawful basis for compounding with them.
• Fake products. FDA has found counterfeit Ozempic and sellers that operate without a prescription or a state license.
• Opened vials. FDA advises discarding a multi-dose vial within 28 days after first use, even if medicine remains or the label allows longer.

Is compounded semaglutide still legal?

The semaglutide injection shortage ended on February 21, 2025, and the temporary flexibility FDA allowed during the shortage has ended. Compounding is still allowed under conditions, but pharmacies generally may not regularly make copies of an approved drug. One exception is when a prescriber documents that a change produces a significant difference for an identified patient. Lower price or an added vitamin does not qualify by itself.

What should you check before starting?

1. A real evaluation. A licensed provider should review your health history, current medicines and goals before prescribing.
2. The pharmacy. The label should name a state-licensed pharmacy. Avoid any seller that offers semaglutide without a prescription.
3. The ingredients. Confirm the active ingredient and everything else in the vial. If the label lists semaglutide sodium or semaglutide acetate, contact your provider and pharmacist before using it.
4. The dose in writing. Your instructions should state the dose in milligrams and the exact amount to draw in milliliters or syringe units. Use the syringes supplied with your prescription and ask for help before your first injection if anything is unclear.
5. Storage and dates. Check the beyond-use date, storage temperature and how long an opened vial can be used.
6. Who to call. Know how to reach the provider and the pharmacy if you have side effects or questions.
