Class II U.S. Food and Drug Administration

Island Kinetics, Inc. d.b.a. CoValence Laboratories Blemish Spot Treatment 1% recall: Failed Stability Specifications

Recall published 6 months ago

Failed Stability Specifications

The hazard: Potency, impurity or stability failure

An out-of-specification result prompted this notice — potency, an impurity, or stability over the shelf life.

What the notice says: Failed Stability 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.

  1. Check the lot number on your pack against the codes listed above before you do anything else.
  2. Keep the carton and the leaflet — the lot number is usually printed only on the outer pack.

What the company owes you

A recalled medicine is the manufacturer’s cost to carry, not yours or your pharmacist’s.

  • The purchase price or co-pay is refundable, and so is the cost of returning the product if they ask you to ship it.
  • Ask the pharmacy to handle the claim where they can — they process recall returns in bulk and it saves you the correspondence.
  • Keep the carton, the leaflet and the pharmacy label together until the claim is closed.
  • Costs beyond the price of the medicine need to go to the company directly, in writing, with the recall number quoted.
