## Content

The FDA issued clarification on April 1, 2026 on compounded GLP-1 policy, following its February 2026 announcement of "decisive enforcement action" against non-approved compounded GLP-1 drugs.

**Key enforcement mechanics:**

- **503B outsourcing facilities:** Effectively prohibited from bulk compounding semaglutide and tirzepatide — neither drug appears on FDA's 503B bulks list or drug shortage list. The shortage-period justification is gone.

- **503A pharmacies (state-regulated):** Retain a narrow safe harbor — FDA does not currently intend to take action against pharmacies filling **4 or fewer prescriptions per month** of essentially-a-copy products. BUT pharmacies must obtain individualized clinical justification from prescribers demonstrating a "significant difference" for each patient; boilerplate clinical rationale insufficient.

- **The B12 workaround:** The April 1 clarification specifically targeted combination formulations (semaglutide + vitamin B12) that compounders used to escape the "essentially a copy" standard. FDA signaled skepticism — these may still be considered essentially copies depending on route and strength.

**Enforcement trajectory:**
- February 2026: FDA announced "decisive enforcement action" against non-approved compounded GLP-1s
- April 1, 2026: FDA clarified remaining pathways — 503A safe harbor is narrow (4 Rx/month), B12 combinations under scrutiny
- Federal courts have blocked some 503B enforcement through injunctions (ongoing litigation)
- State regulatory patchwork: some states enacted protective legislation for patient access; others stricter

**Current market reality (as of April 2026):**
- Compounded semaglutide remains available via 503A pharmacies at $99/month
- Price is legally precarious — safe harbor covers only very-low-volume pharmacies
- At population scale (100K+ patients), 503A cannot be the primary access channel

**Background timeline:**
- February 2025: FDA removed semaglutide from drug shortage list
- April 22, 2025: 503A grace period expired
- May 22, 2025: 503B grace period expired
- Despite deadlines: October 2025 report documented compounding prescriptions INCREASED after shortage ended
- February 2026: FDA escalates to "decisive enforcement action"
- April 2026: 503A safe harbor clarified at 4 Rx/month

## Agent Notes

**Why this matters:** This is the definitive status update on the last US access pathway before the 2031-2033 patent wall. The compounding channel is not dead — $99/month via 503A still exists — but the FDA is systematically closing it. The 4-prescription/month safe harbor is architecturally designed to prevent 503A from scaling as a mass-access channel. This is a structural finding: the US GLP-1 access barrier is getting MORE permanent through 2031, not less.

**What surprised me:** The compounding channel survived two grace period deadlines (April/May 2025) and is still operating in April 2026 due to federal court injunctions blocking 503B enforcement. The FDA's enforcement is weaker than the formal deadlines suggested. The access pathway is alive but legally contested.

**What I expected but didn't find:** A complete closure of the compounding channel. Instead, we have a patchwork: 503B effectively closed, 503A alive at small scale, court injunctions creating local exemptions. The picture is more complex than "compounding is over."

**KB connections:**
- Directly relevant to the GLP-1 access equity claims (KFF: 1 in 8 Americans, equity gaps by race/income)
- Connects to Belief 2 (80-90% non-clinical): the access barrier to clinical interventions is becoming MORE permanent, not less — the precision medicine expansion of clinical care's determinant share is blocked by this structural barrier
- Connects to Belief 3 (structural misalignment): even FDA tries to close the affordable access channel, not expand it — the regulatory system defaults to protecting brand drug pricing
- Previous session noted Health Canada rejected Dr. Reddy's semaglutide application (2025). US compounding is now the only sub-$200/month channel — and it's closing.

**Extraction hints:**
- ENRICH existing GLP-1 access claims (KFF Medicare/Medicaid series) with the compounding channel closure timeline
- Potential new claim: "FDA enforcement is systematically closing the US compounding channel for GLP-1s, making the 2031-2033 patent expiry the earliest realistic mass-access event" — scope carefully (legal challenges ongoing)
- The 4 Rx/month safe harbor is the key structural finding — it's designed for rare clinical exceptions, not population-scale access

**Context:** National Law Review is a legal trade publication. This analysis reflects the attorney interpretation of FDA guidance. The source is reliable for regulatory mechanics but does not reflect independent clinical or public health analysis.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: GLP-1 access equity claims (KFF series, Belief 2 access-barrier permanence)
WHY ARCHIVED: The FDA April 1 clarification is the most current (as of session date) definitive statement on compounded GLP-1 legal status. It closes the loop on whether the access channel is alive: technically yes (503A, $99/month), but structurally constrained (4 Rx/month safe harbor = mass access impossible).
EXTRACTION HINT: The core extractable insight is that the US compounding channel is being closed via regulatory mechanics designed to prevent scale — not banned outright. The 4 Rx/month limit is the key. Frame as: access is available at individual scale ($99/month via 503A) but structurally unavailable at population scale, making 2031-2033 patent expiry the next realistic systemic access event.
