These rows are manufacturer reports to the FDA for Peginterferon Alfa-2A Injection — they do not necessarily cover every manufacturer that makes this drug. A company appears here only if it told the FDA it has a supply problem, so other makers may still have stock.

Why is Peginterferon Alfa-2A Injection in shortage?

The shortage of this specific product comes down to a regulatory delay — meaning there's some kind of hold-up in the approval or compliance process that has to be resolved before more product can be supplied. pharma& (pharmaand GmbH) reported this is affecting only one particular version of their Pegasys injection: the 180 mcg/1 mL package size. According to what they've shared with the FDA, they expect to have a clearer timeline for restocking sometime in Q1 2027 or earlier.

It's worth knowing that the other version — 180 mcg/0.5 mL — is still listed as available from this same manufacturer. So it's really just that one specific package size that's caught up in this regulatory hold-up right now, not the medication as a whole from this company.

Based on the manufacturer-reported reason(s) and notes on file with the FDA for Peginterferon Alfa-2A Injection, summarized in plain English by HelloPharmacist. A drug can be short for more than one reason, and the FDA updates these as manufacturers report changes.

What should I do if I take Peginterferon Alfa-2A Injection?

Peginterferon Alfa-2A injection (brand name Pegasys) is currently on the FDA shortage list. Since this involves an injectable medicine, I want to walk you through the details calmly so you can find the strength you use.

The two strengths are affected differently. The 180 ug/0.5 mL strength still has an available source. The 180 ug/1 mL strength currently has no available source. If you use the 0.5 mL prefilled syringe, supply is reported as available; if you use the 1 mL form, that is the one on hold right now.

The reported reason is a regulatory delay, and this situation has lasted over a year. For the affected 180 ug/1 mL strength, the manufacturer notes a replenishment timeline to be confirmed sometime in Q1 2027 or earlier. This report reflects one manufacturer, so this is not a comment on every possible source.

Here are your next steps:

  • Do not stop, skip, or change your dose on your own.
  • If you use the 0.5 mL strength, ask your pharmacy to order it — they can check wholesalers and manufacturers.
  • If your strength cannot be found, ask your prescriber or pharmacist about options, such as a clinician-chosen adjustment.
  • Manufacturer contact numbers are listed on this page for reference; pharmacies usually handle these calls.

This is general, national information and may not match your local pharmacy's stock.

If you are a patient:
  • Don’t stop or change the medication on your own — talk to your prescriber first.
  • If this is part of an ongoing or essential regimen (for example HIV treatment or prevention, seizure, heart, transplant, diabetes or mental-health medicines), do not skip or ration doses — contact your pharmacist or prescriber right away to arrange continued supply before you run out.
  • Ask your pharmacy to check other manufacturers, strengths, package sizes, and nearby stores.
  • Ask your prescriber whether a different strength, formulation, or the brand/generic version is appropriate.

Shortage records come from the FDA Drug Shortages Database API via openFDA (/drug/shortages) — drug, manufacturer & contact, NDC/product, status, availability, reason, therapeutic category and posting/update dates. Current / To Be Discontinued = active; Resolved is kept for history. The Supply-Risk rating is assessed per active ingredient and adds the FDA NDC Directory (still-marketed manufacturers by ingredient & form); same-medicine and equivalent products use First Databank classification + CMS NADAC pricing; Medicaid use + most-affected states come from CMS Medicaid State Drug Utilization Data. Reference only — confirm current status with the manufacturer or FDA before acting on it.
