If you compound a product in advance, how much are you allowed to make at a time?

• A. A 7 day supply
• B. A 30 day supply
• C. A 14 day supply
• D. A 90 day supply

Answer: (B)

When you compound a product in advance, you’re balancing convenience with keeping the product safe and effective. The amount you can prepare ahead of time is generally limited by how long the compounded formulation remains stable and uncontaminated under proper storage. The standard practice is to prepare a 30-day supply, assuming you have appropriate stability data and storage conditions. This timeframe allows you to dispense a patient’s prescription without frequent re-compounding while still safeguarding potency and quality. Shorter windows would mean more frequent compounding, and a much longer window like 90 days is typically not supported by stability data for most compounded products. If a specific formulation has proven longer stability and the prescriber approves, longer quantities could be possible, but 30 days is the common guideline.
