Can a doctor prescribe this?

Small pharmacy (503A)
Never put forward to FDA
Large outsourcing facility (503B)
Never put forward to FDA

Not approved and not on the compounding list. It was not part of the July 2026 review.

503A is a pharmacy making a single prescription for one patient. 503B is a facility making batches. They are governed by separate lists. Where a category is shown, it is a position on the FDA's list of substances that have been put forward and are still being worked through — not the final list, which is set by rulemaking. Category 1 means the FDA does not plan to act against a pharmacy that makes it while the review runs.
