How to Prepare Your Formulary List for a Compounding Pharmacy

Start with the list, not the sales call

When a clinic or telehealth program starts looking for a compounding pharmacy, the first conversation often stays general. The fastest way to find out whether a pharmacy fits your program is to send it your formulary: the preparations your prescribers actually write, laid out so the pharmacy can answer item by item. A clear list turns "can you help us?" into a specific yes for each line, or a specific next step.

What to put on each line

For every preparation your prescribers order, or plan to order, include:

• The active ingredient or ingredients. If two or more actives go into one preparation, list them together on one line.
• The dosage form. Cream, olive oil base topical, capsule, tablet, topical solution, vaginal preparation and so on. If the form can vary, say so.
• The strengths your protocol uses. List the range your prescribers write, not just the most common one.
• Any base or excipient requirement. Dye-free, a hypoallergenic base, or an ingredient a patient group cannot tolerate.
• Rough volume, if you know it. Even an estimate helps the pharmacy plan.

A spreadsheet works well. One row per preparation keeps it easy to read and easy to answer.

Flag what is commercially available

Mark any line where a commercially manufactured product already exists in the same strength and form. A 503A pharmacy compounds against patient-specific prescriptions and does not compound preparations that are essentially copies of a commercially available product. Where your prescriber orders a strength that is not manufactured, a combination that is not sold, or an excipient change a patient needs, compounding fits. Our post on documenting a significant difference covers what that note on the prescription should say.

Commercially manufactured medications can often still be dispensed on a patient-specific prescription and shipped alongside anything compounded. If your program pairs several products, say so on the list, because we can prepare them together and assemble a single prescription kit built to your protocol.

Tell the pharmacy how orders will arrive

Add a short note on how your prescribers send prescriptions today. Most larger programs connect by direct API, and e-prescribing and a provider portal work too. If you want orders to ship in your own branding, mention that as well. We offer full white-label fulfillment, with your packaging, labels and marketing inserts.

What happens after you send it

At ProCompounding, our team reviews the list and tells you item by item what we can prepare. Where a preparation is new to us, our formula development team can work through it with your medical team in scheduled planning meetings ahead of launch, then research, develop and test it before it is rolled out to your staff.

From there, you complete clinic onboarding. We set up your account, introduce your dedicated account manager, review your prescribing workflow and confirm the clinical and operational details. Our formulary catalog is shared once onboarding is complete.

Why this matters for your patients

A pharmacy that has seen your list before your first prescription arrives can tell you up front what fits, so your patients are not caught between a prescription and a pharmacy that cannot fill it. ProCompounding is a PCAB-accredited 503A compounding pharmacy in Johnson City, Tennessee, licensed in all 50 states and the District of Columbia, with a 48-hour compounding time on most preparations. Shipping time is additional.

If you would like to see how fulfillment works for a specific therapy area, our pages on BHRT fulfillment and men's health fulfillment are good places to start. When your list is ready, start clinic onboarding and tell us about your program.
