Questions for a preparation made for you

# How does compounding change the questions?

A pharmacist or doctor can prepare medicine for an individual order; that process is compounding. Ask why that preparation fits your needs and whether its ingredient is permitted.

## Questions to work through

Ask what need the preparation would meet.

Food and Drug Administration is the agency’s name, shortened to FDA.

When the approved medicine cannot address a patient’s medical need or cannot be obtained, compounding may help, FDA explains in its position recorded September 26, 2026.

Which feature of this preparation addresses a need for you? Ask the clinician to describe it.

Keep the review limit in view.

Safety, quality and whether a made-to-order medicine works go unchecked by FDA before sale; this was the position on September 26, 2026.

Ask about the ingredient itself.

US ingredient rules recorded September 26, 2026 limit which raw ingredients a pharmacy can use when preparing medicine for individual patients.

If an official United States Pharmacopeia or National Formulary standard exists for the ingredient, the pharmacy must follow it. These are written quality rules. The pharmacy must also follow their rules for making the medicine.

Without an ingredient standard, the rule requires an ingredient found in a medicine that has FDA approval. When neither route fits, the ingredient has to appear on FDA’s permitted-ingredient list for this kind of compounding.

The ingredient must also come with a valid report of testing and be made by an FDA-registered business. A prescription alone does not remove these requirements.

## Withdrawing an ingredient request grants no permission

People or groups asked FDA to consider allowing BPC-157 and TB-500 as raw ingredients for compounding, then took back those requests. TB-500 is a short piece of the larger peptide called thymosin beta-4. FDA’s page current to April 22, 2026 lists these requests as withdrawn.

FDA still prints its safety concerns beside those ingredients. As of September 26, 2026, taking back the requests had not given permission to compound them.

## An important limit on copies

US rules recorded September 26, 2026 bar a pharmacy or doctor from making essentially the same medicine as a ready-made product already sold, either regularly or in unusually large amounts.

A change made for an individual patient takes the medicine outside this copy rule if the prescriber judges the difference significant for that patient. The difference must be in the medicine, not just a lower price.

For example, compounding can meet a need for a patient who is allergic to a dye or cannot swallow a tablet.

Ask the prescriber to explain the proposed change to your medicine and why it matters in your case. Ask the prescriber to write the reason down.

Keep this thought

Made to order describes a process. It does not establish approval or permission for every ingredient.

## Notes for this question

### [FDA: reasons for compounding](https://www.fda.gov/drugs/human-drug-compounding/compounding-and-fda-questions-and-answers)

Sets out patient needs and the limits of the review process.

### [FDA: which raw ingredients may be used](https://www.fda.gov/drugs/human-drug-compounding/bulk-drug-substances-used-compounding-under-section-503a-fdc-act)

Explains the raw-ingredient rules for pharmacies making medicines for individual patients.

### [FDA: withdrawn ingredient requests](https://www.fda.gov/drugs/human-drug-compounding/certain-bulk-drug-substances-use-compounding-may-present-significant-safety-risks)

FDA still lists safety concerns after the requests were taken back. This list does not give permission to use the ingredients.

### [FDA: claims about compounded drugs](https://www.fda.gov/drugs/human-drug-compounding/fda-telehealth-companies-what-know-when-promoting-compounded-drugs)

Calling a compounded preparation identical to an approved medicine, or saying their results are proven to match, is false or misleading according to FDA.
