Dermatology Prescriptions & Compounding Questions

Dermatology prescriptions often require more than the drug name alone. Topical products can differ by active ingredient, strength or concentration, and dosage form such as cream, ointment, lotion, gel, or solution. Those differences can affect the product a pharmacy must dispense, so the prescription and label should be matched carefully.

Dosage form is part of the product identity

A cream and an ointment containing the same active ingredient are not automatically the same prescription product. Likewise, gels, lotions, and solutions have different formulations and may have different labeling or package sizes. When researching a dermatology prescription, confirm the exact active ingredient, concentration or strength, dosage form, and package information.

Brand, generic, and commercially available products

FDA-approved generic drugs are required to meet FDA standards for the same active ingredient, strength, dosage form, route of administration, quality, and intended use as the reference brand product. However, different topical products can still have different inactive ingredients, packaging, or appearance. If a prescriber specifies a particular formulation or if the patient has a known ingredient sensitivity, that detail should be reviewed with the pharmacist.

Compounded preparations are a separate category

Compounding can occur under different federal frameworks. Under section 503A, compounding by a licensed pharmacist or physician is generally associated with valid prescriptions for identified individual patients, subject to the applicable statutory conditions, including limited anticipatory compounding. Section 503B outsourcing facilities operate under a separate federal framework and may compound drugs with or without patient-specific prescriptions, subject to that framework. FDA explains that a compounded drug may be considered when an FDA-approved product is not medically appropriate for a particular patient, such as when a needed dosage form or ingredient profile is not available in an approved product.

Compounded drugs are not FDA-approved. FDA does not review compounded drugs for safety, effectiveness, or quality before marketing in the same way it reviews approved drug products. A compounded preparation should therefore not be described as FDA-approved, safer, better, or automatically equivalent to an FDA-approved product.

Storage and labeling questions

Topical prescriptions may have product-specific storage instructions, package sizes, applicators, or warnings. Compounded preparations can also carry a beyond-use date and directions that differ from commercially manufactured products. Follow the exact dispensing label and ask the pharmacist about any storage or handling point that is unclear rather than applying instructions from a different cream, ointment, or solution.

Questions to confirm before a fill

• What is the exact active ingredient and concentration?
• Is the prescription for a cream, ointment, lotion, gel, solution, or another dosage form?
• Is there a commercially available FDA-approved product that matches the prescription?
• If a compounded preparation is being considered, what patient-specific need is the prescriber addressing?
• What storage, beyond-use, or package instructions apply to the exact dispensed product?

Compounding decisions belong with the prescriber and appropriately licensed pharmacy. This page does not state that Davidson currently compounds any particular dermatology medication or formulation. Availability of a specific product or strength should be confirmed with a licensed pharmacy.
