Care notes / Made-to-order medicine

Made to order needs a reason you can understand.

Compounding is making a medicine to meet a particular need. Ask why that need remains unmet by a ready-made medicine.

Facts checked as of September 26, 2026.

A patient need versus a lower advertised price

The patient need

FDA is short for Food and Drug Administration. In the US, this agency reviews medicines.

FDA says preparing medicine to order may fit a patient whose need cannot be met with an approved medicine, or when an approved medicine is unavailable to buy. a

Ask what your specific need is and what would change in the medicine to meet it.

The lower advertised price

As of September 26, 2026, federal rules limited made-to-order copies of medicines already available. b

Under the patient-specific copying rule, a change must make a significant difference for the patient, as decided by the person writing the prescription. Paying less does not qualify as that difference.

For example, FDA uses “essentially a copy” for a medicine whose main drug ingredient is the same, whose strength is similar, and whose way of being taken matches an available medicine.

Price and the reason for compounding need separate answers.

Made for one named patient versus made in larger amounts

Medicine for a named patient

Under the part of federal law called 503A, a licensed pharmacist or doctor prepares medicine under a valid prescription for an identified patient. b

Other rules in that law also have to be met.

A registered medicine-making facility

The part of federal law called 503B covers places that register with FDA to make sterile medicines. Sterile means free of living germs. c

These places can make larger amounts at one time, including for clinics or hospitals. They may make medicine without a prescription naming one patient.

They must follow federal factory quality rules, and FDA inspects them.

Being registered does not give their medicines FDA approval.

Neither set of rules gives the made-to-order medicine FDA approval.

Ask who made it and why

As of September 26, 2026, compounded medicines still lacked FDA review of safety, benefit, and quality before reaching patients. a

Ask which pharmacy or facility made your medicine, and get its name. Ask whether it follows the rules for a named patient’s prescription or for a registered medicine-making facility.

Ask why an approved option does not meet the need, what information supports the proposed change, and who handles any problems.

A clear answer explains why this medicine fits your need. It does not stop at “custom”.

Ask for the medical reason in ordinary words, then check the maker’s name.
