The Food and Drug Administration's Center for Veterinary Medicine is alerting veterinarians of revised directions for use of Eqvalan (ivermectin) Liquid for horses.
The CVM has received a small number of reports of precipitate forming in opened or leaky bottles. As a result of these reports, the directions for use will now instruct that the contents of the bottles be used within four hours of opening and that any unused product or unused diluted product be discarded.
Merial Limited, the manufacturer of Eqvalan, is also adding the following instructions regarding the proper disposal: "Disposal: DO NOT FLUSH or pour unused medication in toilet, sink, or drain. Mix unused medication with cat litter, sawdust (or other material that absorbs the medication), then place in a sealed container (e.g., plastic bag) BEFORE tossing in trash for disposal in a landfill or by incineration."
Veterinarians should examine the product before use. If a precipitate is found, veterinarians should contact Merial Customer Care at (888) 637-4251.
Products generic to Eqvalan should also be examined for precipitate before use. If a precipitate is found in a generic product, the manufacturer of that product should be contacted.
