What is a compounding pharmacy?

Compounding is per-prescription preparation, not commercial manufacturing of an approved drug. The FDA's compounding pages are the authority on that distinction.

What is compounded tirzepatide? How do you get compounded tirzepatide? PinwellRx is a telehealth service headquartered in Houston. If a licensed clinician prescribes, a licensed U.S. 503A pharmacy prepares the medication and ships it. PinwellRx is not itself the compounding pharmacy. Quality rests on the licensed pharmacy that prepares each dose, and on the clinician who decided the prescription was appropriate.

What is section 503A?

Section 503A is the federal compounding framework for state-licensed pharmacies preparing medications for identified patients pursuant to a prescription. The FDA publishes compounding laws and policies on that section.
