What Should Patients Know Before Filling a Compounded Prescription?

A compounded prescription can look and feel different from a standard manufactured medication because it is prepared for an individual patient's prescription. Knowing what to ask before the medication is prepared can make the process clearer and help the pharmacy address important patient-specific details.

Confirm the prescribed dosage form and strength

Make sure you understand what your prescriber ordered. A compounded prescription may be written as a cream, gel, liquid, capsule, suppository, troche, or another suitable dosage form depending on the prescription and pharmacy capabilities.

The prescribed strength may also differ from standard commercially available strengths. If the label or directions are not clear, ask the pharmacist before using the medication.

Tell the pharmacy about relevant allergies or sensitivities

Patients should share known medication allergies and important sensitivities with both the prescriber and the pharmacy. Depending on the formulation, certain inactive ingredients may sometimes be adjusted when clinically appropriate and technically feasible.

An ingredient request is not automatically possible. The pharmacist must confirm that the requested preparation can be made appropriately and legally.

Ask about storage and handling

A compounded medication may have storage instructions that differ from another product with a similar active ingredient. Some preparations may need refrigeration, protection from light, special measuring devices, or other handling instructions.

Follow the label and pharmacy guidance for the specific prescription rather than assuming that instructions for another version of the medication are interchangeable.

Understand how and when to use the preparation

The prescriber's directions determine how the medication should be used. If the dosage form is unfamiliar, ask the pharmacist to explain the administration method and any preparation-specific considerations.

Do not change the amount, frequency, route, or method of use without speaking with the prescriber or pharmacist.

Ask what to do if you have a question after pickup

Patients should know how to reach the pharmacy if a question comes up after dispensing. Questions about appearance, measuring, storage, refills, or use are easier to address when the pharmacy can review the actual prescription and formulation.

For new symptoms, side effects, treatment changes, or medical concerns, contact the prescribing healthcare professional as appropriate.

Remember that compounded drugs are different from FDA-approved drugs

Compounded drugs can serve an important medical need for some patients, but they are not FDA-approved. That means FDA does not review them before marketing for safety, effectiveness, or quality in the same way it reviews approved medications.

A note about compounded medications

Compounded medications are prepared for individual patient needs when appropriate and are not FDA-approved. FDA does not review compounded drugs for safety, effectiveness, or quality before they are marketed. Availability depends on the prescription, clinical appropriateness, ingredient eligibility and availability, pharmacy capabilities, and applicable law.
