Class III U.S. Food and Drug Administration

Island Kinetics, Inc. d.b.a. CoValence Laboratories Skin Rehab recall: Subpotent Drug

Recall published 6 months ago

Subpotent Drug

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: Subpotent Drug

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

Island Kinetics, Inc. d.b.a. CoValence Laboratories — This is a specification failure: testing showed the product does not match what the label promises.

  1. Check the lot number on your pack against the codes listed above before you do anything else.
  2. Do not stop a prescription on your own. For most conditions an uncertain dose is safer than no dose while you get advice.
  3. Call your prescriber or pharmacist and ask whether to swap the lot, re-test, or change nothing.
  4. Keep the carton and the leaflet — the lot number is usually printed only on the outer pack.

Refunds and replacements

With medicines, a replacement supply matters more than cash, and that is what pharmacies are set up to provide.

  • 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 the recall voided a fill you had already paid for, your insurer will normally authorise a replacement ahead of schedule. Quote the recall number.
  • If you paid out of pocket, ask for a refund of the co-pay or purchase price and keep the receipt the pharmacy issues.
