⚠ Critical Legal Notice — This Is Educational Content, Not Legal Advice
This document provides high-level educational information about pharmaceutical compounding regulations, FDA enforcement trends, and compliance workflow considerations. It is NOT legal advice, regulatory counsel, or jurisdiction-specific compliance guidance.
Compounding regulations vary significantly by state, are subject to frequent legislative and regulatory changes, and are interpreted and enforced differently across jurisdictions. The information presented in this document reflects the regulatory landscape as of February 2026 and may be outdated by the time of reading.
HolistiCare.io does not provide legal services, regulatory consulting, or compliance certification. Nothing in this document should be construed as a representation that following the described practices will ensure regulatory compliance or prevent enforcement action.
Practices MUST consult with qualified legal counsel licensed in their jurisdiction, state board of pharmacy counsel, and regulatory compliance specialists before making any compounding, prescribing, or operational decisions. Failure to obtain jurisdiction-specific legal guidance creates significant regulatory and legal risk.
Abstract
Pharmaceutical compounding exists in one of the most complex and rapidly evolving regulatory environments in medicine. The 2013 Drug Quality and Security Act (DQSA) created a dual-track framework — Section 503A traditional compounding and Section 503B outsourcing facilities — that fundamentally changed how compounded drugs are regulated. Since then, FDA enforcement has intensified, state boards of pharmacy have expanded oversight, and the line between permissible compounding and illegal drug manufacturing has become both more clearly defined and more aggressively policed.
For functional medicine practices prescribing compounded peptides, hormones, or other non-FDA-approved therapeutics, understanding the regulatory framework is not optional. The gap between ‘what we have always done’ and ‘what is currently permissible’ has widened significantly in the past five years. Practices operating on outdated compliance assumptions face warning letters, consent decrees, and in extreme cases, criminal referrals.
This brief provides a high-level educational overview of the current compounding regulatory landscape, recent enforcement trends, and workflow considerations for maintaining compliance. This is not a compliance manual — it is a map of where the regulatory boundaries are and where enforcement pressure is concentrating. Specific compliance strategies must be developed with legal counsel.
I. The Dual-Track Regulatory Framework: 503A vs. 503B
The foundational question in compounding compliance is: which regulatory track applies to your practice’s compounding relationships? The answer determines what is permissible, what documentation is required, and what enforcement risk exists.
1.1 Section 503A: Traditional Compounding Pharmacies
Section 503A pharmacies are state-licensed compounding pharmacies that operate under an exemption from FDA drug approval requirements, provided they comply with specific conditions:
CRITICAL: 503A pharmacies are regulated primarily by state boards of pharmacy, not FDA. However, FDA retains enforcement authority and has increasingly used it when state oversight is deemed inadequate.
1.2 Section 503B: Outsourcing Facilities
Section 503B outsourcing facilities are entities that have elected to register with FDA and operate under more stringent federal oversight in exchange for greater flexibility:
Most functional medicine practices source peptides and compounded hormones from 503B facilities due to the interstate distribution flexibility. However, 503B status does NOT mean FDA-approved — it means FDA-registered and subject to federal oversight.
⚖ When to Consult Legal Counsel: Compounding Source Verification Consult legal counsel if: • Your practice is unsure whether your compounding pharmacy is 503A or 503B • You are sourcing compounded drugs from out-of-state pharmacies (interstate commerce triggers additional federal jurisdiction) • Your pharmacy cannot provide current state licensure or FDA 503B registration documentation • You are considering compounding in-house at your practice (physician office compounding has separate and more restrictive rules) • Your state board has issued guidance that conflicts with your understanding of federal compounding rules
II. Recent Enforcement Trends: Where FDA and State Boards Are Focusing
Regulatory risk is not evenly distributed. FDA and state boards of pharmacy concentrate enforcement efforts on specific high-risk categories and practice patterns. Understanding where enforcement pressure is highest allows practices to allocate compliance resources more effectively.
2.1 Trend 1: 'Essentially a Copy' Violations
One of the most frequently cited violations in recent FDA warning letters is compounding of drugs that are ‘essentially a copy’ of commercially available FDA-approved products. This prohibition exists in both 503A and 503B frameworks, but enforcement has intensified.
Examples from recent enforcement actions:
- Compounding semaglutide for weight loss when commercially available Wegovy exists (multiple warning letters issued 2023-2025)
- Compounding testosterone preparations in standard strengths/formulations when FDA-approved products are available
- Compounding thyroid hormone combinations (T3/T4) that do not significantly differ from FDA-approved products
The defense against ‘essentially a copy’ allegations requires documented clinical rationale: Why is the commercially available product unsuitable for this patient? Common acceptable rationales include: documented allergy to inactive ingredients, required non-standard dosing, required alternate delivery route not commercially available.
CRITICAL: ‘Patient preference’ or ‘cost’ are NOT acceptable rationales under current FDA interpretation. The clinical necessity must be documented.
2.2 Trend 2: Bulk Drug Substances Not on FDA's List
503B facilities may only compound from bulk drug substances that appear on FDA’s list of bulk drug substances for compounding. This list is periodically updated and is publicly available. Compounding from non-listed substances is a violation.
Recent enforcement has targeted:
- Peptides marketed for ‘research purposes’ but compounded into patient prescriptions (BPC-157, TB-500, others)
- ‘Bioidentical’ hormone formulations from non-FDA-listed hormone precursors
- Novel nootropics and cognitive enhancers not on bulk substance list
For 503A pharmacies, the standard is different — they can compound from any USP-grade or equivalent substance. However, if FDA determines that large-scale compounding of a non-listed substance constitutes manufacturing rather than compounding, the 503A exemption may not protect the pharmacy.
⚖ When to Consult Legal Counsel: Bulk Substance Compliance Consult legal counsel if: • You are prescribing peptides or other compounds that do not appear on FDA's bulk drug substances list for 503B compounding • Your compounding pharmacy has received FDA communication questioning the source or status of bulk substances • You are uncertain whether a substance you prescribe is USP-listed or FDA-approved for compounding • Your practice has received patient inquiries or complaints about 'research peptides' or 'not FDA-approved' disclaimers
2.3 Trend 3: Sterile Compounding Insanitary Conditions
Sterile compounding violations — particularly contamination, inadequate environmental controls, and failure to follow USP <797> — remain the highest-priority enforcement target for both FDA and state boards. Recent enforcement actions have resulted in facility closures, product recalls, and in one case, criminal prosecution.
High-risk areas:
- Inadequate environmental monitoring (air quality, surface contamination)
- Personnel training and qualification deficiencies
- Lack of sterility testing or beyond-use-date validation
- Failure to investigate contamination events or customer complaints
For prescribing practices, the due diligence obligation is clear: verify that your compounding pharmacy can demonstrate USP <797> compliance through recent state board inspection reports, environmental monitoring data, and documented training programs.

III. Workflow Considerations for Compliance-Conscious Practices
Compliance is not a periodic audit activity. It is an operational workflow design problem. Practices that build compliance verification into standard workflows — rather than treating it as an external checklist — experience fewer violations and faster resolution when issues arise.
3.1 Prescription Documentation Standards
The single most common documentation deficiency in compounding compliance audits is inadequate prescription records. State boards and FDA expect to see:
- Valid prescriber-patient relationship documented (initial consultation note, ongoing treatment relationship)
- Prescription with patient name, medication, strength, quantity, directions, prescriber signature, date
- Clinical rationale for compounding documented in chart (why is compounded product necessary vs. FDA-approved alternative?)
- Informed consent documentation that patient was informed product is compounded and not FDA-approved
HolistiCare’s clinical intelligence platform automates several of these documentation requirements by generating structured clinical notes with embedded compliance fields, compounded prescription templates with required elements, and patient consent forms with regulatory language.

3.2 Vendor Compliance Monitoring
Prescribing practices have a legal and professional obligation to verify that their compounding pharmacy vendors remain compliant with applicable regulations. This is not a one-time verification — it is an ongoing surveillance obligation.
Minimum monitoring cadence:
- Quarterly: Review FDA warning letter database for your compounding pharmacies
- Quarterly: Request updated state pharmacy license and 503B registration (if applicable)
- Annually: Request copy of most recent state board inspection report
- Annually: Review pharmacy’s quality metrics (batch rejection rate, customer complaint rate, adverse event reports)
- Event-triggered: Immediate review if patient reports adverse event or product quality concern
AI-assisted vendor monitoring tools can automate FDA warning letter surveillance, certificate expiration tracking, and adverse event correlation — reducing manual review burden from ~2 hours/quarter to ~15 minutes/quarter per vendor.

3.3 Adverse Event Reporting Obligations
This is an area of significant confusion and underreporting. Prescribing practices may have adverse event reporting obligations to FDA under the MedWatch program, depending on the circumstances of the event and the product involved.
General framework (NOT legal advice — verify with counsel):
- Healthcare practitioners are encouraged (not required) to report serious adverse events to FDA MedWatch for all drugs, including compounded drugs
- 503B facilities ARE required to report adverse events to FDA
- If a pattern of adverse events emerges from a specific compounded product or batch, prescribing practice may have heightened reporting obligation
Best practice: treat all adverse events involving compounded products as reportable and establish a structured adverse event documentation and reporting workflow.
⚖ When to Consult Legal Counsel: Adverse Event Reporting Consult legal counsel if: • A serious adverse event (hospitalization, permanent disability, death) occurs in association with compounded drug use • Multiple patients report similar adverse events from same compounded product or lot • State board or FDA contacts practice requesting information about adverse events • Practice is uncertain whether an event meets 'serious adverse event' threshold requiring reporting
IV. State-Level Variation: Why Federal Compliance Is Not Sufficient
A common and dangerous compliance assumption is that if a practice’s compounding relationships are compliant with federal (FDA) standards, state-level compliance is automatically satisfied. This is incorrect. State pharmacy laws and regulations often impose requirements that exceed federal minimums.
4.1 Areas of Common State-Federal Divergence
The operational implication: federal compliance is necessary but not sufficient. State-specific compliance review is mandatory and must be conducted by counsel licensed in that state.
⚖ When to Consult Legal Counsel: Multi-State Practice Compliance Consult legal counsel if: • Your practice operates in multiple states or prescribes across state lines via telehealth • You are sourcing compounded drugs from out-of-state pharmacies for in-state patients • State board of pharmacy has issued guidance or enforcement action that appears to conflict with federal rules • Your practice is considering physician office compounding or in-house preparation of any compounded products • You are prescribing compounded controlled substances (pain management, ADHD medications, etc.)
V. Emerging Issues: Areas of Regulatory Uncertainty and Evolving Enforcement
The compounding regulatory landscape is not static. Several areas of active legal and regulatory development will likely see clarification — and potentially new enforcement — in the next 12-24 months.
5.1 Telehealth and Interstate Prescribing of Compounded Drugs
The expansion of telehealth during COVID-19 created significant ambiguity around interstate prescribing of compounded drugs. The core tension: a physician licensed in State A prescribes a compounded drug via telehealth to a patient in State B, and the compound is shipped from a pharmacy in State C. Which state’s pharmacy and medical practice laws govern?
Current regulatory posture (subject to change):
- DEA rules: Prescriber must be licensed in state where patient is located at time of consultation
- Pharmacy rules: Pharmacy must be licensed in state where patient will receive the drug (State B)
- Medical practice rules: Prescriber must comply with State B’s prescriber-patient relationship requirements, even if licensed in State A
Several states have issued conflicting guidance on this issue. Federal legislation to create uniform interstate telehealth prescribing standards has been proposed but not enacted as of February 2026.
5.2 'Wellness' and 'Anti-Aging' Compounded Peptides
Peptides marketed for longevity, athletic performance, cognitive enhancement, and other non-FDA-approved indications present significant regulatory risk. FDA has stated that many peptides currently being compounded and prescribed do not have a recognized medical indication and may not be eligible for compounding under 503A or 503B frameworks.
Specific enforcement concerns:
- BPC-157, TB-500, and similar peptides: not on FDA’s bulk substances list for 503B; compounding may not be permissible
- Growth hormone secretagogues (ipamorelin, CJC-1295, etc.): FDA has questioned whether these constitute new drugs requiring approval
- Nootropic peptides (Selank, Semax): similar concerns about lack of recognized medical use
This is an area of active legal uncertainty. Practices prescribing these peptides should maintain close consultation with legal counsel and be prepared for potential enforcement action.
⚖ When to Consult Legal Counsel: Emerging Regulatory Issues Consult legal counsel if: • Your practice prescribes peptides or other compounds that do not have FDA-approved indications • Your compounding pharmacy has been contacted by FDA or state board regarding products your practice prescribes • You operate a telehealth practice prescribing compounded drugs across state lines • Marketing materials or patient communications reference 'anti-aging,' 'performance enhancement,' or other non-medical claims • Your practice has received media inquiries or patient complaints about 'unapproved drugs' or 'research chemicals'
VI. Building a Compliance-Oriented Workflow: Operational Recommendations
Compliance cannot be retrofitted. It must be designed into clinical workflow from the outset. What follows are operational recommendations — not legal requirements, but structural practices that reduce compliance risk.
6.1 Establish a Compounding Compliance Committee
For practices that prescribe significant volumes of compounded medications (>100 prescriptions/month), formal governance structure is advisable. A Compounding Compliance Committee should include:
- Medical director or prescribing physician
- Practice administrator or operations manager
- External legal counsel (advisory role)
- Pharmacist consultant (if available)
Committee responsibilities:
- Quarterly review of compounding vendor compliance status
- Annual review of practice’s compounding policies and documentation standards
- Review and approval of new compounding vendors before use
- Investigation of adverse events involving compounded products
- Liaison with state board and FDA if enforcement inquiry occurs
6.2 Implement Structured Consent and Documentation Protocols
Every compounded prescription should trigger a structured documentation workflow:
- Clinical rationale documentation: Chart note specifying why compounded product is medically necessary vs. FDA-approved alternative
- Patient informed consent: Documented conversation that patient understands product is compounded, not FDA-approved, and may carry different risks
- Prescription documentation: Complete prescription with all required elements (patient name, strength, quantity, directions, prescriber signature, date)
- Vendor verification: Confirmation that pharmacy is state-licensed and (if 503B) FDA-registered
- Adverse event monitoring: Follow-up documentation at defined intervals to assess tolerability and efficacy
HolistiCare’s clinical platform automates this workflow with templated clinical notes, embedded consent forms, and automatic vendor verification checks.

6.3 Maintain an Audit-Ready Documentation System
If your practice receives a state board inquiry, FDA inspection, or subpoena, the ability to produce complete, organized documentation quickly is operationally and legally critical. Best practices:
- Maintain centralized electronic records for all compounded prescriptions (not scattered across paper charts)
- Tag records with ‘compounded medication’ flag for easy retrieval
- Generate periodic audit reports showing: total compounded prescriptions by drug, by pharmacy, adverse event correlation
- Retain vendor compliance documentation (licenses, inspection reports, certificates) in searchable database
- Document all communications with compounding pharmacies regarding quality concerns, adverse events, or regulatory inquiries
The standard is: if asked to produce all documentation related to a specific compounded product or vendor, your practice should be able to do so within 48 hours. If that is not currently achievable, your documentation system needs redesign.

VII. Conclusion: Compliance as Operational Discipline, Not Aspiration
The compounding regulatory environment is not forgiving of well-intentioned non-compliance. FDA and state boards do not substantially differentiate between ‘we didn’t know’ and ‘we knew and chose not to comply’ when issuing enforcement actions. The standard is constructive knowledge — what a reasonable, diligent practitioner should know about applicable regulations.
This brief has outlined the major regulatory frameworks, recent enforcement trends, workflow considerations, and areas of legal uncertainty. What it has not done — and cannot do — is provide jurisdiction-specific compliance advice. That requires legal counsel licensed in your state, familiar with your practice’s specific operations, and current on evolving state and federal guidance.
The operational imperative is clear: build compliance into workflow design, not as an external audit function. Automate documentation where possible. Maintain continuous vendor surveillance. Document clinical rationale rigorously. Establish governance structures for oversight and response.
Practices that operate on the assumption that ‘everyone else is doing it’ or ‘we’ve never had a problem’ are operating on borrowed time. Enforcement trends are tightening. Regulatory scrutiny is increasing. The practices that survive and thrive in this environment are those that treated compliance as operational discipline from the outset — not as a response to enforcement.
HolistiCare exists to provide the operational infrastructure — structured documentation, automated compliance checks, vendor surveillance, audit-ready reporting — that makes compliance systematically achievable rather than heroically dependent on individual vigilance.
Consult counsel. Build systems. Document everything. The regulatory landscape is navigable, but it requires navigational instruments.
