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.
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.
Veterinary drug refund and professional consultation.
