Class II U.S. Food and Drug Administration

Zydus Pharmaceuticals Inc Entecavir Tablets, USP, 0.5 mg, 30 Tablets recall: Failed Impurity/Degradation Specifications

Recall published 1+ years ago

Failed Impurity/Degradation Specifications

The hazard: Potency, impurity or stability failure

The recall concerns the strength or purity of the medicine rather than contamination of it, which changes what you should do about a dose you have already taken.

What the notice says: Failed Impurity/Degradation Specifications

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.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.

What to do about Potency

Zydus Pharmaceuticals Inc — The recall concerns the strength or purity of the medicine rather than contamination of it, which changes what you should do about a dose you have already taken.

  1. Check the lot number on your pack against the codes listed above before you do anything else.
  2. Call your prescriber or pharmacist and ask whether to swap the lot, re-test, or change nothing.
  3. Keep the carton and the leaflet — the lot number is usually printed only on the outer pack.
  4. Report any change in how the medicine is working to FDA MedWatch, which is where most of these signals originate.

Getting a replacement supply

Do not let a refund question interrupt your treatment. Deal with the supply first and the money second.

  • Call the pharmacy before you run low. They can see which lot they dispensed to you and will usually swap it the same day.
  • Insurers do not normally count a recall replacement against a refill limit. If one is refused, ask the pharmacist to call it through as a recall override.
  • Over-the-counter products are refunded at the till like any other purchase; the recall notice on your phone is enough to explain the return.
  • If the manufacturer runs a direct reimbursement form, it will be linked from the official notice on this page.
