The short answer
Compounded preparations have not received approval, as of September 2026, from the Food and Drug Administration (FDA). Before marketing, they receive no agency review for quality, effectiveness or safety.
There can be a real reason for it
The FDA describes compounding for medical needs an approved product cannot meet, including omitting a dye because of an allergy.
A reason for compounding and permission to use a particular ingredient are separate questions. Ask about both.
A prescription does not explain the ingredient rule
As of September 2026, federal law limits the raw ingredients that an ordinary compounding pharmacy may use.
Raw ingredient means the starting substance used to prepare the medicine.
Ask the clinician to explain which rule applies to that ingredient. Ask the pharmacy the same question. A reply that only says “made for you” leaves the ingredient question unanswered.
Identify who makes it
With online services, the compounder behind a medicine may be unclear to the patient, the FDA notes.
- What need is the preparation meant to meet?
- Which pharmacy or facility would prepare it?
- What is the full ingredient name?
- Who can explain the product and answer later questions?
Get those names before comparing an offer with another one. It is easier to check a specific preparation than a broad description.
Carry this forward
Ask why it is being made to order, what permits the ingredient, and who will prepare it.
