What does “compounded” mean here?
A compounded drug is prepared for a patient through a compounding process rather than marketed as an FDA-approved finished drug product. Compounded does not mean generic, equivalent, FDA-approved or automatically unsafe. It describes a different regulatory and preparation pathway.
What concerns has FDA published?
FDA has reported concerns involving compounded semaglutide and tirzepatide, including fraudulent products, dosing errors and adverse-event reports. FDA has also warned that semaglutide salt forms such as semaglutide sodium and semaglutide acetate differ from the active ingredient used in approved drugs.
What should a patient verify?
Clinical attributes
- Licensed prescriber
- Documented medication name
- Clear dose and titration plan
- Side-effect instructions
- Follow-up contact path
Pharmacy and product attributes
- Legitimate dispensing pharmacy
- Readable label
- Concentration and units
- Storage requirements
- Administration instructions
Why are dosing units important?
Compounded injectable products may use vials and syringes rather than manufacturer single-dose devices. If a prescription is expressed in milligrams but a syringe is marked in volume or “units,” the patient needs explicit conversion instructions from the healthcare team. FDA has linked some serious events to dosing errors.
When should someone seek medical help?
Side effects and urgent-warning signs depend on the specific medication and patient. Follow the prescriber's instructions and the applicable product information. Severe or rapidly worsening symptoms, signs of a serious allergic reaction or another medical emergency require prompt professional care.

Why does FDA warn about compounded semaglutide dosing?
FDA has received reports of dosing errors with compounded injectable semaglutide, including errors in measuring and administering doses.
What should I verify about a compounded product?
