Who prepares it?
A licensed pharmacist or doctor can prepare a compounded medicine, as can a registered outsourcing facility.
A pharmacist is a health professional who prepares or supplies medicines.
Registered means the facility has submitted its details for an FDA list; that listing is not approval of its medicines.
An outsourcing facility makes batches of medicine under a separate set of compounding rules.
When can it make sense?
FDA, the U.S. drug agency, says a custom preparation may fit a need an approved product cannot meet.
Examples include being allergic to a dye in the product or finding a tablet hard to swallow.
Ask what the specific need is in your case.
Has the finished preparation been approved?
Compounded drugs lack FDA approval; their quality, benefit and possible harm receive no FDA check before marketing, as of September 2026.
Poor preparation can leave unwanted matter in the medicine, or the wrong amount of the ingredient meant to do the work.
Ask who makes it and which record you can check.
Does a larger facility change the answer?
A registered outsourcing facility follows federal factory quality rules and is subject to FDA inspection as of September 2026.
That registration is not an approval of its products.
Inspecting how a facility makes medicine is different from approving the finished medicine.
What can I take away?
Ask why a custom preparation is needed and who is responsible for making it.
