Compounded vs. FDA-Approved Oxytocin: What’s the Difference?
FDA-approved oxytocin (such as Pitocin) is an injection approved only for obstetric uses like inducing labor. Oxytocin nasal sprays and dissolving tablets are compounded medications: prepared by a licensed pharmacy for an individual patient from a prescription, and not FDA-approved for the uses they’re prescribed for.
Key takeaways
- The only FDA-approved oxytocin products today are injections for obstetric use.
- 503A compounding pharmacies make patient-specific nasal sprays and tablets.
- Compounded drugs are legal but haven’t been through FDA approval for safety and effectiveness.
- Pharmacy licensing and quality testing are what you should check.
FDA-approved oxytocin
Injectable oxytocin is FDA-approved to start or strengthen labor and to help control bleeding after childbirth. It’s given in hospitals under close monitoring. It isn’t prescribed for home use or for mood or relationship goals.
Compounded oxytocin
Compounding is when a licensed pharmacist prepares a medication for a specific patient, for example in a dosage form that isn’t commercially available. Because no FDA-approved oxytocin nasal spray has been sold in the US since 1997, nasal sprays and under-the-tongue tablets come from compounding pharmacies.
What is a 503A pharmacy?
Section 503A of the federal Food, Drug, and Cosmetic Act covers traditional compounding pharmacies, which prepare medications for individual patients based on a prescription and are overseen mainly by state boards of pharmacy. Section 503B covers “outsourcing facilities” that make larger batches under closer FDA oversight, mostly for clinics and hospitals.
Is compounded oxytocin safe?
Compounded medications are legal, but the FDA has not evaluated them for safety, effectiveness or quality the way it evaluates approved drugs. Quality depends heavily on the pharmacy. Look for state licensing in your state, adherence to USP compounding standards, and, ideally, accreditation and third-party potency testing.
