Questions
Straight answers.
No. On October 28, 2026, the U.S. Department of Health and Human Services issued an interim enforcement-discretion policy: it does not intend to act against licensed pharmacies that compound this substance from a patient-specific prescription, under set conditions, while the FDA finishes its rulemaking. That is not FDA approval. The substance has not been evaluated by the FDA for safety, effectiveness, or quality the way an approved drug is, and it has not been added to the FDA's 503A bulk drug list; an FDA advisory committee recommended adding it in July 2026 and the FDA has not decided. The policy is temporary and can change.
