Chiesi USA, Inc. Revcovi Injection, 2.4mg/1.5mL , Single-Dose Vial recall: Failed Stability Specifications: Out of specification stability result
Failed Stability Specifications: Out of specification stability result for the protein concentration profile.
The hazard: Potency, impurity or stability failure
This is a specification failure: testing showed the product does not match what the label promises.
What the notice says: Failed Stability Specifications: Out of specification stability result for the protein concentration profile.
Why it matters: The product failed a specification test: it may contain more or less active ingredient than the label states, carry an impurity, or degrade before its expiry date. A sub-potent dose can leave a condition untreated; a super-potent one can cause an overdose.
Symptoms and when to call a doctor
The risk depends entirely on the drug. For a medicine where dose matters closely — a blood thinner, an anti-epileptic, a thyroid or heart medicine, insulin — talk to your prescriber before changing anything. Seek urgent care if you have symptoms that suggest too much drug, or if the condition the medicine controls starts breaking through.

Chiesi USA, Inc. — This is a specification failure: testing showed the product does not match what the label promises.
- Check the lot number on your pack against the codes listed above before you do anything else.
- Keep the carton and the leaflet — the lot number is usually printed only on the outer pack.
- Report any change in how the medicine is working to FDA MedWatch, which is where most of these signals originate.
- Do not stop a prescription on your own. For most conditions an uncertain dose is safer than no dose while you get advice.

- Ask the dispensing pharmacy for a like-for-like replacement from an unaffected lot. This is the fastest route and usually costs nothing.
- For a mail-order or online pharmacy, use the recall line listed on this page rather than the general support queue.

- If you paid out of pocket, ask for a refund of the co-pay or purchase price and keep the receipt the pharmacy issues.
