Schering Plough Animal Health Corporation: Phenylzone Oral Paste Recalled Due to Dosing Errors from Incorrect Plungers

Agency Publication Date: April 10, 2007

Sign in to monitor this recall

Summary

Schering Plough Animal Health Corporation is recalling 12,774 units of Phenylzone Oral Paste (phenylbutazone), a medication used for horses. Some syringes in lot #028051 were manufactured with incorrect plungers that are calibrated based on animal weight rather than the required grams of phenylbutazone delivered. This defect can lead to inaccurate dosing, potentially resulting in under-treatment or over-treatment of the animal. If you have this product, you should contact your veterinarian or pharmacist for guidance on how to return the unused medication for a refund.

Risk

The incorrect plunger markings mean the user may deliver an inappropriate dose of phenylbutazone because the scale does not match the actual amount of medication being dispensed. This could lead to toxic effects from an overdose or a lack of therapeutic effect from an underdose.

What You Should Do

  1. Check your Phenylzone Oral Paste (6 gram syringe) packaging for NDC number 0061-5045-01 and Lot Number 028051.
  2. Verify if the plunger markings are calibrated in 'animal weight' instead of 'grams of phenylzone' — if they are marked by weight, the product is affected.
  3. Immediately stop using the affected syringes to avoid incorrect dosing of your animal.
  4. Contact your veterinarian, veterinary college, or distributor where the product was purchased to arrange for a return and refund.
  5. Contact Schering Plough Animal Health Corporation at their Summit, New Jersey office for further instructions regarding this recall.
  6. For additional questions, contact the FDA Center for Veterinary Medicine at 1-240-402-7002.
