When Might a Healthcare Provider Consider Compounding?

Compounding may be considered when a patient's medication needs cannot be met appropriately by a standard commercially available option. The decision begins with the treating provider, while the pharmacy evaluates the requested formulation for feasibility, prescription requirements, ingredient eligibility, and applicable law.

When an available strength does not fit the prescription

A provider may need a patient-specific strength that is not readily available as a manufactured product. In those situations, the pharmacist can review whether the prescribed strength can be prepared in an appropriate dosage form.

The pharmacy does not select the therapeutic dose. The prescriber determines the treatment plan and requested strength.

When a different dosage form may be appropriate

A patient may have difficulty using a particular manufactured dosage form, or the treatment plan may call for a different route or formulation. Depending on the prescription, a pharmacy may be able to prepare an oral liquid, capsule, topical preparation, or another suitable dosage form.

The requested dosage form must still be appropriate for the ingredient, patient, route of administration, and pharmacy's compounding capabilities.

When certain inactive ingredients need review

Some patient-specific prescriptions involve consideration of dyes, flavors, fillers, bases, or other inactive ingredients. When feasible, a formulation may sometimes be adjusted around a documented patient need.

A request to remove or change an ingredient requires pharmacy review because the formulation still has to be technically sound and suitable for the prescribed use.

When the pharmacy and provider need to coordinate

Compounding often involves direct pharmacist-provider communication. The pharmacist may need to clarify the intended strength, vehicle, dosage form, ingredient compatibility, directions, or other formulation details before preparation.

This collaboration is particularly important when a prescription is highly customized or when the requested formulation is unusual.

What the pharmacy evaluates before accepting the prescription

A compounded prescription has to be clinically appropriate for the requested use, technically feasible, legally eligible, and within the pharmacy's capabilities. Ingredient availability and regulatory limitations can affect whether a formulation can be prepared.

Not every requested drug or formulation can be compounded, and legal status can change. When there is uncertainty, the pharmacist may need additional information or may determine that the requested preparation cannot be filled.

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.
