Which peptide drugs are in FDA shortage?
Live from the FDA shortage database — and what each shortage means for legal compounding.
Short answer: As of September 21, 2026, 12 peptide and peptide-derived drugs appear on the FDA drug shortage list: 14 entries are an active (current) shortage and 25 are listed as to be discontinued. Shortage status matters legally because a drug in shortage may be compounded in ways it cannot be once the shortage resolves.
GLP-1 and metabolic peptides
Liraglutide 9 current 2 to be discontinued
Insulin 7 to be discontinued
Semaglutide 3 to be discontinued
Pramlintide 2 to be discontinued
Hormone and endocrine peptides
Desmopressin 4 current
Somatropin 1 to be discontinued
Other therapeutic peptides
Icatibant 2 to be discontinued
Peptide antibiotics and antifungals
Bacitracin 1 current
Caspofungin 3 to be discontinued
Daptomycin 2 to be discontinued
Micafungin 2 to be discontinued
Vancomycin 1 to be discontinued
Why shortage status decides whether compounding is legal
A drug shortage is not just a supply problem — it changes what compounding pharmacies may lawfully make. Normally a compounder may not produce a drug that is "essentially a copy" of a commercially available FDA-approved product. That restriction does not apply while the drug sits on the FDA shortage list, which is why compounded GLP-1s were legal during the semaglutide and tirzepatide shortages and became violations once FDA declared those shortages resolved.
What is permitted during a shortage
- 503A pharmacies may compound the drug against a valid prescription
- 503B outsourcing facilities may produce it for healthcare facilities
- The "essentially a copy" restriction is waived for the drug in shortage
What is still required
- Proper pharmacy or outsourcing-facility licensing
- Quality and safety standards, including appropriate ingredient sourcing
- Accurate labeling
What happens when the shortage ends
- FDA publishes notice that the shortage is resolved
- Compounders must stop producing copies of the drug
- A transition period may apply, after which patients move back to the commercial product
What to do during a shortage
For patients
- Contact your pharmacy about availability and check more than one
- Ask your prescriber about therapeutic alternatives
- Ask whether a legally compounded option applies to your drug
- Do not stop a prescribed medication without medical guidance
For healthcare providers
- Monitor FDA shortage notifications for status changes
- Identify therapeutic alternatives before supply runs out
- Confirm a drug is still listed in shortage before relying on compounded supply
Frequently asked questions
Which peptide drugs are currently in FDA shortage?
As of September 21, 2026, 12 peptide and peptide-derived drugs appear on the FDA drug shortage list: 14 entries are an active (current) shortage and 25 are listed as to be discontinued. Shortage status matters legally because a drug in shortage may be compounded in ways it cannot be once the shortage resolves.
Can a peptide be legally compounded during an FDA shortage?
Yes. While an FDA-approved drug is on the FDA shortage list, 503A pharmacies and 503B outsourcing facilities may compound versions of it because the "essentially a copy of a commercially available drug" restriction does not apply to a drug in shortage. Once FDA declares the shortage resolved, that permission ends and compounders must stop producing copies.
Why did compounded semaglutide and tirzepatide become illegal?
Compounded semaglutide and tirzepatide were lawful only because both drugs sat on the FDA shortage list. When FDA declared those shortages resolved, the shortage-based exception that permitted compounding disappeared, and compounding copies of them became an "essentially a copy" violation.
